This is happening for me too - any movement on this?

Hello @manishsharma28 !

What does the output of

cat aoi.geojson | supermercado burn 19

look like? Also could you provide be with a sample of aoi.geojson?

[JmeCS]

After some additional troubleshooting, it looks like it was unhappy due to a MULTIPOLYGON geometry type in my geojson. @manishsharma28 - if your geojson contains multipolygons, try exploding them into polygons and see if that fixes the problem.

Hi, any activity on this? I am facing the same issue.

Hi, I have the geojson file which can reproduce the issue. Shall I share?

After some additional troubleshooting, it looks like it was unhappy due to a MULTIPOLYGON geometry type in my geojson. @manishsharma28 - if your geojson contains multipolygons, try exploding them into polygons and see if that fixes the problem.

I tried exploding. But it does not seem to work.

@INF800 thanks for posting your data file. In it I see the following

"crs": { "type": "name", "properties": { "name": "urn:ogc:def:crs:EPSG::32643" } }

Your data is not strict GeoJSON. Supermercado requires your coordinates to use the standard OGC:CRS84 system (longitude and latitude using WGS84). You must reproject your data from EPSG:32643 to OGC:CRS84.

[rozeappletree]

@sgillies It is NOT working (or am I making some mistake?). Thankyou for responding.

Detailed description:

I used these options to export the polygon using QGIS

And the file after exporting looks like this:
aoi_ogc_crs_84.geojson

{
"type": "FeatureCollection",
"name": "aoi_ogc_crs_84",
"features": [
{ "type": "Feature", "properties": { "id": 0 }, "geometry": { "type": "MultiPolygon", "coordinates": [ [ [ [ 286093.184368180751335, 2122448.917276436462998 ], [ 285839.117529983399436, 2123632.333864882122725 ], [ 286340.56523695186479, 2123665.763712013605982 ], [ 286474.284625476808287, 2122512.433985985815525 ], [ 286093.184368180751335, 2122448.917276436462998 ] ] ] ] } },
{ "type": "Feature", "properties": { "id": 1 }, "geometry": { "type": "MultiPolygon", "coordinates": [ [ [ [ 286514.400442034238949, 2122529.148909551557153 ], [ 286360.623145230580121, 2123662.420727300457656 ], [ 286731.694448387250304, 2123672.449681439902633 ], [ 286915.558607609069441, 2122689.612175781745464 ], [ 286514.400442034238949, 2122529.148909551557153 ] ] ] ] } }
]
}

Now, I want to burn the polygon with id==0 - which is saved in trn_aoi.geojson. So I use:

aoi_df = gpd.read_file('/src/data/thane/aoi_ogc_crs_84.geojson').explode()
aoi_df[aoi_df['id']==0].to_crs("OGC:CRS84").to_file('trn_aoi.geojson', driver='GeoJSON')

trn_aoi.geojson:

{
"type": "FeatureCollection",
"features": [
{ "type": "Feature", "properties": { "level_0": 0, "level_1": 0, "id": 0 }, "geometry": { "type": "Polygon", "coordinates": [ [ [ 286093.184368180751335, 2122448.917276436462998 ], [ 285839.117529983399436, 2123632.333864882122725 ], [ 286340.56523695186479, 2123665.763712013605982 ], [ 286474.284625476808287, 2122512.433985985815525 ], [ 286093.184368180751335, 2122448.917276436462998 ] ] ] } }
]
}

Finally I run the burn command which results in error

$ cat trn_aoi.geojson | supermercado burn 19 | mercantile shapes | fio collect

Please note that ERROR 1: PROJ: proj_create_from_database: Open of /opt/conda/envs/solaris/share/proj failed has nothing to do with the issue because in another case (with another geojson file), the same appoach gave expected results even with the above ERROR 1
