About KML

Keyhole Markup Language (KML) is an XML-based format for displaying geographic data in Earth browsers like Google Earth. It supports styling, icons, and 3D features.

Extensions: .kml
Software: Google Earth, Google Maps, QGIS, ArcGIS, Cesium
Limitations: Requires WGS 84 (EPSG:4326). Can become very large for complex datasets. Limited attribute handling.

About CSV

Comma-Separated Values (CSV) files store tabular data with coordinate columns (latitude/longitude or WKT geometry). A simple, universal format supported by virtually all data tools.

Extensions: .csv
Software: Excel, Google Sheets, QGIS, Python/Pandas, R
Limitations: No built-in geometry type — requires coordinate columns. No CRS metadata. No support for complex geometries without WKT.
