Two things, from the same hands
A surveyor who measures land in El Salvador, and the programs he wrote to do it. What brings you here?
Surveying software
For surveyors, in any country
TopoMan CAD — which reads and writes DWG without AutoCAD — and the add-in for the AutoCAD you already use. Both download and run without paying.
See the softwareSurveying services
In El Salvador only
Land measurement, surveys, segregations, partitions and the drawing ready to file. With GNSS and total station.

The programs did not come out of a software office: they came out of measuring land here and needing tools that did not exist.
