SAS.Planet

Complete desktop GIS application written in Delphi: download, cache and view maps and satellite imagery from many providers offline, with GPS tracks, waypoints, layers, geotagging and export to common map formats. A substantial reference for how a large Object Pascal application separates its data layer, business logic, user interface and error handling (GPL-3.0 - strong copyleft).
