What is a WKT file?
WKT (well-known text) writes a shape as text, such as POINT (13.4 52.5). Databases like PostGIS, SQL Server and Oracle use it; EWKT adds an SRID in front.
Each geometry sketched, with a table of them, and the map on request when the numbers are longitude and latitude. Text shows the file.
