> As I'm working with CAD for a long time, I would recommend to install next three FLOSS apps (keep them all side-by-side on your PC): Do any of these easily let you build a map from only the distances between two landmarks? I've been wanting to make an accurate map of the trees in my yard. That should be pretty easy to turn into a map using basic trig, but I don't want to do it by hand.

FreeCAD has a 2D constraints-based solver (the sketch workbench) which could be used for this.

> Do any of these easily let you build a map from only the distances between two landmarks? I've been wanting to make an accurate map of the trees in my yard. Use QGIS[0] or OpenOrienteering Mapper[1] (simpler than QGIS) app for any GIS/cartography/mapping tasks. JFTR, GIS apps are "CAD for cartography"; FreeCAD/QCAD/SolveSpace are "CAD for civil engineering", but could be used for some GIS tasks. Anyway, OpenOrienteering Mapper & QGIS are CAD apps You are looking for!

  They're not really the same thing. I haven't found GIS apps to have the _parametric_ abilities that would allow the GP to perform the sort of constraint-based modelling they desire.

Could use Geogebra. https://www.geogebra.org/ https://www.geogebra.org/

Get an older Garmin Etrex with a digital compass. These models have a sight line on the housing. You use this to project waypoints along a heading. If you traverse a base line and make two projections beyond the tree you will have four waypoints. The target will be at the intersection.
