Can my AI agent convert MapInfo TAB Dataset to TOPOJSON?
Yes. Install the Filestar CLI with npm install -g filestar and your agent can run filestarcli -i file.tab -c "convert to topojson" on your computer, so your files stay on it.
A MapInfo TAB dataset describes geographic features and their attributes. Its text .tab header refers to companion .dat, .map and .id files, which must be kept together. It is not tab-separated text (TSV).
TopoJSON is a file format for encoding geographic data structures, based on the GeoJSON format. It encodes geometries more efficiently and supports topology, which enables more accurate representations of geographic objects. TopoJSON eliminates redundancy and simplifies data, making it smaller and easier to work with.
