As a user/admin, when I am in the Geoengine Demo module and I go to + the ZIP menu. When I click on an item in the list view, I get to the + form view showing me the different information about the ZIP. We can + see its ZIP, city, priority, total sales and his spatial + representation. +2. As a user, I can't modify the information in the form view. +3. As an admin, I can modify the information in the form view. I can + click on the bin button to clear the map and I can draw a new shape. +4. As a user, when I go the "Retail machines" tab and there are no + items to display, it does not show me anything. +5. As an admin, when I go the "Retail machines" tab and there are no + items to display, the list view of the retail machines suggests to + me to add a new line. +6. As a user/admin, if there are items to be displayed in the "Retail + machines" tab then I can click on an item and the retail machines + form view will be displayed. We can see its spatial representation + by going to "The point" tab and its attributes in "Attributes" tab. +7. As a user/admin, when I go to the geoengine zip view by clicking on + the map button at the top right of the screen. The geoengine view + appears with the first 80 results displayed on the map. The vector + layers selected are those defined as "active on startup" by the + admin. The selected raster layer is the first one that is not an + overlay layer. +8. As a user/admin, when I hover over an area on the map, the area + changes its style. +9. As a user/admin, when I click on an area, a popup appears an I can + see the different information about the area. If I click on the + cross, the popup will disappear. If I click somewhere else on the + map, the popup will also disappear. If I click on the about button, + then the form view will be displayed. +10. As a user/admin, when I use the paging system, then the results + displayed on the map are different (corresponding to the request). +11. As a user/admin, if we use the search bar, we can search results by + his zip or his city. +12. As an admin, if I change the sequence of layers with the handle + button then the change are persisted in database. +13. As a user, if I change the sequence of layers with the handle button + then the change are not persisted in database. There are just the + changes in the display. +14. As an admin, if I change the domain of a layer with the filter + button then the change are persisted in database. +15. As a user, if I change the domain of a layer with the filter button + then the change are not persisted in database. There are just the + changes in the display. +16. As an admin, I have the possibility to edit the layer with its + corresponding button. +17. As a user/admin, I can open/close LayerPanel with its button. +18. As a user/admin, I can open/close RecordsPanel with its button. +19. As a user/admin, when I click on a record in RecordsPanel, a move is + made on the map to the selected record. +20. As a user/admin, when I click on a record in RecordsPanel, I can + also click on the left magnifying glass to zoom on the record. +21. As a user/admin, when I click on a record in RecordsPanel, I can + also click on the right magnifying glass to get the original zoom. +22. As a user/admin, I can use the search bar to search in the + RecordsPanel. +23. As an admin,If the geoengine view is in edit mode, I can create new + records by drawing them in the view. +24. As an admin, If the geoengine view is in edit mode, I can modify its + spatial representation. + +Geoengine Backend +----------------- + +1. As an admin, if I go into the configuration of the raster layers and + it has elements, I can click on one and see its information. +2. As an admin, if I want to create a new raster layer, I can click on + "NEW" and fill out the form. The required fields for OpenStreetMap + type are "Layer Name" and "Related View". If we want to have a WMTS + (Web Map Tile Service) raster type. The required fields in addition + to the precedents are "Service URL", "Matrix set","Format", + "Projection" and "Resolutions". If we take WMS (Web Map Service) + raster type, then the required fields are "Layer Name", "Related + View", "Service URL", "Params", "Server Type". +3. As an admin,if I go into the configuration of the vector layers and + it has elements, I can click on one and see its information. +4. As an admin, if I want to create a new vector layer, I can click on + "NEW" and fill out the form. The required fields are "Layer Name", + "Related View", "Geo field" and "Representation mode". + +Known issues / Roadmap +====================== + + + +Changelog +========= + +16.0.1.0.0 (2023-03-20) +----------------------- + +- LayerSwitcher has been removed as it was not really practical. A + LayerPanel is now active. +- The geo_search method is now deprecated and replaced by the standard + odoo search method. +- The widget "geo_edit_map" attribute is no longer necessary as the + field is automatically detected by his type. We can also provide an + option attribute that allows us to pass an opacity and a color as + parameters. + +.. code:: xml + +
+ + + + + +
+ +- The method geo_search is now deprecated. We now need to use the + standard odoo search method. + +.. code:: python + + obj.search([("the_point","geo_intersect",{"dummy.zip.the_geom": [("id", "=", rec.id)]})]) + +- We can now pass to the geoengine view a template to display the + information we want to see when clicking on a feature. + +.. code:: xml + + + + + + + + + +

+ + + + +- We can now pass a model to use to a layer to display other information + on the map. + +.. code:: xml + + + + [('state', '=', 'hs')] + + HS retail machines + + basic + + #FF0000 + + 0.8 + + +- There is some new features in the LayerPanel. + +1. If you are logged in as an admin, you have the possibility to edit + the layer by clicking on the edit button. This will open a dialog + box. Changes will appear in real time on the view. +2. If you are logged in as an admin, you can also change the domain of + the layer. If you are logged in as a user, changes will not be + persisted in the database. Changes will appear in real time on the + view. +3. If you are logged in as an admin, you can also change the sequence of + the layers by sliding them over each other. If you are logged in as a + user, changes will not be persisted in the database. + +- Widget domain is now implemented for geo field This means that the + geo-operators are also implemented and that there is the possibility + to add a sub-domain. If we want to add a domain that includes all the + records that are displayed in the geoengine view (active_ids). We can + use the two new operators : "in active_ids" and "not in active_ids". + These will automatically replace the marker with ids. Note that the + widget will indicate that the domain is invalid because of the marker. +- Creation of the RecordsPanel. This panel allows you to retrieve all + active records. You can click on record to get the movement to the + selected record. Two magnifying glass are also available. You can + click on the left one to zoom on the record. You can click on the + right one to get the original zoom. +- A search bar is also available. It allows you to perform a search into + the RecordsPanel. +- A button to open/close the panels is also available. +- The module has been translated in French. +- Now you can now make the geoengine view editable. Simply add editable + attribute in the geoengine view. + +.. code:: xml + + + + + + + + + + +

GeoEngine is an Odoo module that adds spatial/GIS capabilites to Odoo. +It will allow you to :

+
    +
  • Visualize and query your business information on map
    • +
  • Perform GeoBI and spatial query
    • +
  • Configure your spatial layers and spatial datasources
    • +
  • Extend Odoo models with spatial columns
    • +
+

GeoEngine relies on OpenLayers and +PostgGIS technologies.

+

Postgis is used to store spatial information in databases. OpenLayer is +used to represent spatial data in other words to show maps and the +different spatial layers. The GeoEngine module acts as a data provider +and as an OpenLayers configurator. It also provides a complete extension +to Odoo ORM.

Changelog

+
+

16.0.1.0.0 (2023-03-20)

+
    +
  • LayerSwitcher has been removed as it was not really practical. A +LayerPanel is now active.
    • +
  • The geo_search method is now deprecated and replaced by the standard +odoo search method.
    • +
  • The widget “geo_edit_map” attribute is no longer necessary as the +field is automatically detected by his type. We can also provide an +option attribute that allows us to pass an opacity and a color as +parameters.
    • +
+
+<form>
+    <notebook colspan="4">
+        <page string="Geometry">

+
+
    +
  • The method geo_search is now deprecated. We now need to use the +standard odoo search method.
    • +
+
+obj.search([("the_point","geo_intersect",{"dummy.zip.the_geom": [("id", "=", rec.id)]})])
+
+
    +
  • We can now pass to the geoengine view a template to display the +information we want to see when clicking on a feature.
    • +
+

  • There is some new features in the LayerPanel.
    • +
+
    +
  1. If you are logged in as an admin, you have the possibility to edit +the layer by clicking on the edit button. This will open a dialog +box. Changes will appear in real time on the view.
    2. +
  2. If you are logged in as an admin, you can also change the domain of +the layer. If you are logged in as a user, changes will not be +persisted in the database. Changes will appear in real time on the +view.
    3. +
  3. If you are logged in as an admin, you can also change the sequence of +the layers by sliding them over each other. If you are logged in as a +user, changes will not be persisted in the database.
    4. +
+
    +
  • Widget domain is now implemented for geo field This means that the +geo-operators are also implemented and that there is the possibility +to add a sub-domain. If we want to add a domain that includes all the +records that are displayed in the geoengine view (active_ids). We can +use the two new operators : “in active_ids” and “not in active_ids”. +These will automatically replace the marker with ids. Note that the +widget will indicate that the domain is invalid because of the marker.
    • +
  • Creation of the RecordsPanel. This panel allows you to retrieve all +active records. You can click on record to get the movement to the +selected record. Two magnifying glass are also available. You can +click on the left one to zoom on the record. You can click on the +right one to get the original zoom.
    • +
  • A search bar is also available. It allows you to perform a search into +the RecordsPanel.
    • +
  • A button to open/close the panels is also available.
    • +
  • The module has been translated in French.
    • +
  • Now you can now make the geoengine view editable. Simply add editable +attribute in the geoengine view.

You can get a list of all\n * properties with {@link module:ol/Object~BaseObject#getProperties}.\n *\n * Note that the observable properties are separate from standard JS properties.\n * You can, for example, give your map object a title with\n * `map.title='New title'` and with `map.set('title', 'Another title')`. The\n * first will be a `hasOwnProperty`; the second will appear in\n * `getProperties()`. Only the second is observable.\n *\n * Properties can be deleted by using the unset method.

The projection determines the\n * coordinate system of the center, and its units determine the units of the\n * resolution (projection units per pixel). The default projection is\n * Web Mercator (EPSG:3857).\n *\n * ### The view states\n *\n * A View is determined by three states: `center`, `resolution`,\n * and `rotation`. Each state has a corresponding getter and setter, e.g.\n * `getCenter` and `setCenter` for the `center` state.\n *\n * The `zoom` state is actually not saved on the view: all computations\n * internally use the `resolution` state. Still, the `setZoom` and `getZoom`\n * methods are available, as well as `getResolutionForZoom` and\n * `getZoomForResolution` to switch from one system to the other.\n *\n * ### The constraints\n *\n * `setCenter`, `setResolution` and `setRotation` can be used to change the\n * states of the view, but any constraint defined in the constructor will\n * be applied along the way.\n *\n * A View object can have a *resolution constraint*, a *rotation constraint*\n * and a *center constraint*.\n *\n * The *resolution constraint* typically restricts min/max values and\n * snaps to specific resolutions. It is determined by the following\n * options: `resolutions`, `maxResolution`, `maxZoom` and `zoomFactor`.\n * If `resolutions` is set, the other three options are ignored. See\n * documentation for each option for more information. By default, the view\n * only has a min/max restriction and allow intermediary zoom levels when\n * pinch-zooming for example.\n *\n * The *rotation constraint* snaps to specific angles. It is determined\n * by the following options: `enableRotation` and `constrainRotation`.\n * By default rotation is allowed and its value is snapped to zero when approaching the\n * horizontal.\n *\n * The *center constraint* is determined by the `extent` option. By\n * default the view center is not constrained at all.\n *\n * ### Changing the view state\n *\n * It is important to note that `setZoom`, `setResolution`, `setCenter` and\n * `setRotation` are subject to the above mentioned constraints. As such, it\n * may sometimes not be possible to know in advance the resulting state of the\n * View. For example, calling `setResolution(10)` does not guarantee that\n * `getResolution()` will return `10`.\n *\n * A consequence of this is that, when applying a delta on the view state, one\n * should use `adjustCenter`, `adjustRotation`, `adjustZoom` and `adjustResolution`\n * rather than the corresponding setters. This will let view do its internal\n * computations. Besides, the `adjust*` methods also take an `anchor`\n * argument which allows specifying an origin for the transformation.\n *\n * ### Interacting with the view\n *\n * View constraints are usually only applied when the view is *at rest*, meaning that\n * no interaction or animation is ongoing. As such, if the user puts the view in a\n * state that is not equivalent to a constrained one (e.g. rotating the view when\n * the snap angle is 0), an animation will be triggered at the interaction end to\n * put back the view to a stable state;\n *\n * @api\n * @extends {BaseObject}\n */\nclass View extends BaseObject {\n /**\n * @param {ViewOptions} [options] View options.\n */\n constructor(options) {\n super();\n\n /***\n * @type {ViewOnSignature}\n */\n this.on;\n\n /***\n * @type {ViewOnSignature}\n */\n this.once;\n\n /***\n * @type {ViewOnSignature}\n */\n this.un;\n\n options = Object.assign({}, options);\n\n /**\n * @private\n * @type {Array}\n */\n this.hints_ = [0, 0];\n\n /**\n * @private\n * @type {Array>}\n */\n this.animations_ = [];\n\n /**\n * @private\n * @type {number|undefined}\n */\n this.updateAnimationKey_;\n\n /**\n * @private\n * @const\n * @type {import(\"./proj/Projection.js\").default}\n */\n this.projection_ = createProjection(options.projection, 'EPSG:3857');\n\n /**\n * @private\n * @type {import(\"./size.js\").Size}\n */\n this.viewportSize_ = [100, 100];\n\n /**\n * @private\n * @type {import(\"./coordinate.js\").Coordinate|undefined}\n */\n this.targetCenter_ = null;\n\n /**\n * @private\n * @type {number|undefined}\n */\n this.targetResolution_;\n\n /**\n * @private\n * @type {number|undefined}\n */\n this.targetRotation_;\n\n /**\n * @private\n * @type {import(\"./coordinate.js\").Coordinate}\n */\n this.nextCenter_ = null;\n\n /**\n * @private\n * @type {number}\n */\n this.nextResolution_;\n\n /**\n * @private\n * @type {number}\n */\n this.nextRotation_;\n\n /**\n * @private\n * @type {import(\"./coordinate.js\").Coordinate|undefined}\n */\n this.cancelAnchor_ = undefined;\n\n if (options.projection) {\n disableCoordinateWarning();\n }\n if (options.center) {\n options.center = fromUserCoordinate(options.center, this.projection_);\n }\n if (options.extent) {\n options.extent = fromUserExtent(options.extent, this.projection_);\n }\n\n this.applyOptions_(options);\n }\n\n /**\n * Set up the view with the given options.\n * @param {ViewOptions} options View options.\n */\n applyOptions_(options) {\n const properties = Object.assign({}, options);\n for (const key in ViewProperty) {\n delete properties[key];\n }\n this.setProperties(properties, true);\n\n const resolutionConstraintInfo = createResolutionConstraint(options);\n\n /**\n * @private\n * @type {number}\n */\n this.maxResolution_ = resolutionConstraintInfo.maxResolution;\n\n /**\n * @private\n * @type {number}\n */\n this.minResolution_ = resolutionConstraintInfo.minResolution;\n\n /**\n * @private\n * @type {number}\n */\n this.zoomFactor_ = resolutionConstraintInfo.zoomFactor;\n\n /**\n * @private\n * @type {Array|undefined}\n */\n this.resolutions_ = options.resolutions;\n\n /**\n * @type {Array|undefined}\n * @private\n */\n this.padding_ = options.padding;\n\n /**\n * @private\n * @type {number}\n */\n this.minZoom_ = resolutionConstraintInfo.minZoom;\n\n const centerConstraint = createCenterConstraint(options);\n const resolutionConstraint = resolutionConstraintInfo.constraint;\n const rotationConstraint = createRotationConstraint(options);\n\n /**\n * @private\n * @type {Constraints}\n */\n this.constraints_ = {\n center: centerConstraint,\n resolution: resolutionConstraint,\n rotation: rotationConstraint,\n };\n\n this.setRotation(options.rotation !== undefined ? options.rotation : 0);\n this.setCenterInternal(\n options.center !== undefined ? options.center : null,\n );\n if (options.resolution !== undefined) {\n this.setResolution(options.resolution);\n } else if (options.zoom !== undefined) {\n this.setZoom(options.zoom);\n }\n }\n\n /**\n * Padding (in css pixels).\n * If the map viewport is partially covered with other content (overlays) along\n * its edges, this setting allows to shift the center of the viewport away from that\n * content.

If `haystack` is an array of strings, use the `literal` operator to disambiguate from an expression:\n * `['literal', ['abc', 'def', 'ghi']]`\n *\n * * Conversion operators:\n * * `['array', value1, ...valueN]` creates a numerical array from `number` values; please note that the amount of\n * values can currently only be 2, 3 or 4 (WebGL only).\n * * `['color', red, green, blue, alpha]` or `['color', shade, alpha]` creates a `color` value from `number` values;\n * the `alpha` parameter is optional; if not specified, it will be set to 1 (WebGL only).\n * Note: `red`, `green` and `blue` or `shade` components must be values between 0 and 255; `alpha` between 0 and 1.\n * * `['palette', index, colors]` picks a `color` value from an array of colors using the given index; the `index`\n * expression must evaluate to a number; the items in the `colors` array must be strings with hex colors\n * (e.g. `'#86A136'`), colors using the rgba[a] functional notation (e.g. `'rgb(134, 161, 54)'` or `'rgba(134, 161, 54, 1)'`),\n * named colors (e.g. `'red'`), or array literals with 3 ([r, g, b]) or 4 ([r, g, b, a]) values (with r, g, and b\n * in the 0-255 range and a in the 0-1 range) (WebGL only).\n * * `['to-string', value]` converts the input value to a string. If the input is a boolean, the result is \"true\" or \"false\".\n * If the input is a number, it is converted to a string as specified by the \"NumberToString\" algorithm of the ECMAScript\n * Language Specification. If the input is a color, it is converted to a string of the form \"rgba(r,g,b,a)\". (Canvas only)\n *\n * Values can either be literals or another operator, as they will be evaluated recursively.\n * Literal values can be of the following types:\n * * `boolean`\n * * `number`\n * * `number[]` (number arrays can only have a length of 2, 3 or 4)\n * * `string`\n * * {@link module:ol/color~Color}\n *\n * @typedef {Array<*>|import(\"../color.js\").Color|string|number|boolean} ExpressionValue\n * @api\n */\n\nlet numTypes = 0;\nexport const NoneType = 0;\nexport const BooleanType = 1 << numTypes++;\nexport const NumberType = 1 << numTypes++;\nexport const StringType = 1 << numTypes++;\nexport const ColorType = 1 << numTypes++;\nexport const NumberArrayType = 1 << numTypes++;\nexport const SizeType = 1 << numTypes++;\nexport const AnyType = Math.pow(2, numTypes) - 1;\n\nconst typeNames = {\n [BooleanType]: 'boolean',\n [NumberType]: 'number',\n [StringType]: 'string',\n [ColorType]: 'color',\n [NumberArrayType]: 'number[]',\n [SizeType]: 'size',\n};\n\nconst namedTypes = Object.keys(typeNames).map(Number).sort(ascending);\n\n/**\n * @param {number} type The type.\n * @return {boolean} The type is one of the specific types (not any or a union type).\n */\nfunction isSpecific(type) {\n return type in typeNames;\n}\n\n/**\n * Get a string representation for a type.\n * @param {number} type The type.\n * @return {string} The type name.\n */\nexport function typeName(type) {\n const names = [];\n for (const namedType of namedTypes) {\n if (includesType(type, namedType)) {\n names.push(typeNames[namedType]);\n }\n }\n if (names.length === 0) {\n return 'untyped';\n }\n if (names.length < 3) {\n return names.join(' or ');\n }\n return names.slice(0, -1).join(', ') + ', or ' + names[names.length - 1];\n}\n\n/**\n * @param {number} broad The broad type.\n * @param {number} specific The specific type.\n * @return {boolean} The broad type includes the specific type.\n */\nexport function includesType(broad, specific) {\n return (broad & specific) === specific;\n}\n\n/**\n * @param {number} oneType One type.\n * @param {number} otherType Another type.\n * @return {boolean} The set of types overlap (share a common specific type)\n */\nexport function overlapsType(oneType, otherType) {\n return !!(oneType & otherType);\n}\n\n/**\n * @param {number} type The type.\n * @param {number} expected The expected type.\n * @return {boolean} The given type is exactly the expected type.\n */\nexport function isType(type, expected) {\n return type === expected;\n}\n\n/**\n * @typedef {boolean|number|string|Array} LiteralValue\n */\n\nexport class LiteralExpression {\n /**\n * @param {number} type The value type.\n * @param {LiteralValue} value The literal value.\n */\n constructor(type, value) {\n if (!isSpecific(type)) {\n throw new Error(\n `literal expressions must have a specific type, got ${typeName(type)}`,\n );\n }\n this.type = type;\n this.value = value;\n }\n}\n\nexport class CallExpression {\n /**\n * @param {number} type The return type.\n * @param {string} operator The operator.\n * @param {...Expression} args The arguments.\n */\n constructor(type, operator, ...args) {\n this.type = type;\n this.operator = operator;\n this.args = args;\n }\n}\n\n/**\n * @typedef {LiteralExpression|CallExpression} Expression\n */\n\n/**\n * @typedef {Object} ParsingContext\n * @property {Set} variables Variables referenced with the 'var' operator.\n * @property {Set} properties Properties referenced with the 'get' operator.\n * @property {boolean} featureId The style uses the feature id.\n * @property {boolean} geometryType The style uses the feature geometry type.\n * @property {boolean} mapState The style uses the map state (view state or time elapsed).\n */\n\n/**\n * @return {ParsingContext} A new parsing context.\n */\nexport function newParsingContext() {\n return {\n variables: new Set(),\n properties: new Set(),\n featureId: false,\n geometryType: false,\n mapState: false,\n };\n}\n\n/**\n * @typedef {LiteralValue|Array} EncodedExpression\n */\n\n/**\n * @param {EncodedExpression} encoded The encoded expression.\n * @param {number} expectedType The expected type.\n * @param {ParsingContext} context The parsing context.\n * @return {Expression} The parsed expression result.\n */\nexport function parse(encoded, expectedType, context) {\n switch (typeof encoded) {\n case 'boolean': {\n if (isType(expectedType, StringType)) {\n return new LiteralExpression(StringType, encoded ?
