hplans is a geojson representation of the LoRaWAN regional parameter channel plans. It is based off of RP2-1.0.3 LoRaWAN Regional Parameters from the LoRaWAN Alliance as well as Helium Networks country definitions. https://lora-alliance.org/resource_hub/rp2-1-0-3-lorawan-regional-parameters/ https://github.com/helium/miner/blob/master/priv/countries_reg_domains.csv
The geojson does not contain the channel plan and spectrum definitions but only the geographic regions they apply to.
These regions are used to determine what channel plan hotspots should be using. When a hotspot's location is asserted the LoRaWAN region is looked up and set depending on its location.
These geojson regions are used by lorawan-h3 to generate binary lists of Uber h3 hex https://github.com/helium/lorawan-h3
h3idx files are created which contain a binary list of user h3 hexes for each region. These files are used by the miner to determine which plan to use.
The dataset was originally download from https://osm-boundaries.com/ based off the regions.csv file using getgeojson.py(this code is no longer used but moved to archive). Each LoRaWAN region is captured in its own file by country.
regions.geojson contains all regions. It is created by running plans.py which takes each region file and runs unary_union function to merge all neighbouring polygons with the same region and combines them all into a single file.
