Forester, not a geospatial or IT professional, currently using QGIS and SAGA for generally county level geoprocessing of multipspectral imagery and DEM's (cluster analysis, zonal statistics, stream channel modeling).
Currently exceeding practical processing limits for laptop/windows configuration using HP EliteBook w/4GB Ram, Intel Core i5, 32 bit Win7 OS. Need advice on logical next step in hardware/OS/software.
Future ambitions include deployment of PostGIS and derivation of canopy height models from stereo matched imagery. Thinking low end workstation and Ubuntu OS.
I'm a one man shop trying to operate a bit beyond my capabilities. I do not speak fluent IT or GIS, need a balance of horsepower, idiot proof, moderate learning curve and intermediate support. Cost is important but functionality, flexibility and capability are primary.
