Kerala-Panchayath-Maps

Python project to generate Kerala's distrcit level panchayath map.

As of now, geojson files of Kollam and Kozhikode are added to the folder geojson_files. So other districts won't work.

Usage

  1. Install requirements using

    pip install -r requirements.txt

  2. Run the below command:

    python map_generator.py -d Kollam -f png -c True

    Here -f and -c are optional arguements.

    For details on arguements, run:

    python map_generator.py -h

    output:

      	optional arguments:
       		-h, --help            show this help message and exit

       -d DISTRICT, --district DISTRICT
                   District name
                   
       -f FORMAT, --format FORMAT
                   Output image format (default: png)
                   
       -c CMAP, --cmap CMAP  
               If coloured map is required, use True. else use False.(default : True)

  3. Map file is generated in maps folder.

Generate GeoJson from OpenstreetMap

    [out:xml][timeout:500];
    {{geocodeArea:Kozhikode district}}->.searchArea;
    (
        nwr["boundary"="local_authority"]["admin_level"="8"](area.searchArea);
    );
    // print results
    out meta;
    >;
    out meta qt;

change district name to desired one.

  • If you know the OSM area code of the district, use the following code in Overpass
    [out:xml][timeout:500];
    area(3602018247)->.searchArea;
    (
    nwr["boundary"="local_authority"]["admin_level"="8"](area.searchArea);
    );
    // print results
    out meta;
    >;
    out meta qt;
