GeoCSV is a recent extension of the CSV file format with an optional extension of geometry. It takes little space and is easy to share.
As the shapefile, it can be accompanied by auxiliary files: .prj (Spatial Reference System), .csvt (field type information), csvz (compression format).
- The WKT option: stores the constructor in a single column of type String, for example "POINT (-4.5454 45.2211)", which means -4.5454 west and 45.2211 north (longitude / latitude). This option supports the geometry types Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon and even GeometryCollection and ARCs.
- The option "Point (X / Y)": can only store points. This type of point geometry is stored in two columns: longitude, latitude (x / y). Example for two columns of coordinates lon and lat is "8.8249; 47.2274"
