About ODS

ODS (OpenDocument Spreadsheet) is an open standard spreadsheet format. Like XLSX, it can serve as a geographic data source when it contains coordinate columns.

Extensions: .ods

Software: LibreOffice Calc, Google Sheets, QGIS, GDAL/OGR, Python

Limitations: No built-in geometry type — requires coordinate columns. No CRS metadata. Limited to tabular point data.

About TopoJSON

TopoJSON is an extension of GeoJSON that encodes topology, eliminating redundancy and reducing file size. Shared boundaries between features are stored only once.

Extensions: .topojson, .json

Software: D3.js, Mapbox, QGIS, GDAL/OGR, Leaflet

Limitations: Read-only in most GIS software. Requires conversion for editing. Less widely supported than GeoJSON.
