Inspired by Carolina Bigonha's br-atlas, this repository is for generating TopoJSON and GeoJSON files for Brazilian maps.
All maps are downloaded from IBGE (Instituto Brasileiro de Geografia e Estatística), the agency responsible for statistical, geographic, cartographic, geodetic and environmental information in Brazil and were published on 2021.
Firstly, this repository depends on Python 3. You may install Python using the source code or a pre-built installer for your platform, all available at Python download page.
You also need GDAL to be installed on you OS and available in your PATH.
The other dependencies are listed in the requirements.txt file and can be installed with pip install -r requirements.txt.
Clone this repository, install the dependencies and run ./pySHPtoJSON.py -h to read the instructions. Make sure that pySHPtoJSON.py file has execution permission.
TopoJSON files will be generated inside topo/ directory.
GeoJSON files will be generated inside geo/ directory.
Running ./pySHPtoJSON.py Brasil will generate TopoJSON and GeoJSON files for
Brazil and ./pySHPtoJSON.py UFs for each of its states, municipalities, macro and microregions. They are located in BR/ and UFs/ subdirectories.
Also, several original compacted shapefiles files are stored: zip directory contains these files downloaded from IBGE. If you wish you may delete this extra directory after conversion.
Binary executables may be generated for each platform by running python3 setup.py build. It will work only on the operational system that generated it.
This command will create a subdirectory called bin with the executable and its needed libraries at a lib directory.
