Archive NZ Wireless Map

Spectrum Search Lite, the database on which this is based, stopped updating on Dec 2022.

However, it's important to note that the database within Spectrum Search Lite is no longer being updated; the last update was performed in December 2022.

The replacement, an online system "Register of Radio Frequencies (RRF)", https://rrf.rsm.govt.nz/ui/search/licence, doesn't seem to export a bulk.

data.govt.nz finds nothing for radio spectrum: https://catalogue.data.govt.nz/dataset?q=radio+spectrum&sort=score+desc%2C+metadata_modified+desc&ext_bbox=

I suppose we could ask for an export. But without updates, we should label the data on nz wireless map as being a snapshot on the website. And turn down the fetch jobs. And probably archive this repository.

• turn down fetch jobs
• archive https://github.com/mhansen/nzwirelessmap-fetch/
• email them https://www.rsm.govt.nz/about/contact-us
• add an archive label to https://wirelessmap.markhansen.co.nz/
• archive this repository

I made an enquiry to Radio Spectrum Management:

Hi Radio Spectrum Managers,

Is there a bulk data API or .zip/.csv file available with the licenses available?

I'm a software engineer who had a hobby project mapping the radio spectrum licenses in New Zealand: https://wirelessmap.markhansen.co.nz/. It was very interesting to make the invisible telecommunication system visible on the map. This website pulled data from the old Spectrum Search Lite .zip file (which was updated weekly, but stopped updating in December 2022).

I see there's an online search, https://rrf.rsm.govt.nz/ui, which is great – congratulations on modernising the system. But it doesn't enable batch use cases like visualising all the links on a map. This is a shame!

Is there any bulk data replacement available? If not, please consider this a 'feature request' to make it available. I imagine your data is stored in a few tables in a database; a .zip file containing a .csv per-table would be a great export format.

Thanks for the consideration
Mark Hansen
