comment How to use qgis coordinate transformation in user code
For some strange reasons, +proj=latlong behaves the same way as +proj=longlat. Try +axis=neu, see trac.osgeo.org/proj/wiki/GenParms#Axisorientation

No, you requested +proj=longlat, that means longitude first. The name of your variable pj_latlong is misleading.

comment Need advice for localized survey base point
Those four corner points seem to fit to each other, so you might take the lower left as new base. I still wonder how the old base got wrong, and how yo ended up in Colorado. The Z coordinate of 1000 feet for the base also does not make sense, if all other points are above 2000 ft.

comment Why are my calls to SAGA routines in QGIS not working cross platform?
I got a reply from the processing developer: lists.osgeo.org/pipermail/qgis-developer/2014-October/…. It seems that current Windows and Linux versions of SAGA are a bit apart, and rapidly changing from version to version.

I remember that openlayers will look up online under spatialreference.org. But that source did not get any maintenance recently.
