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

• goto Overpass and use the code below:

    [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;
