"The technical geography topic presents a range of subjects that provide essential tools to geographical research, teaching, and practice. On one hand it includes geomatics, one of geography’s classical subject matters; on the other it introduces modeling of geographical systems, a field that has gained an important place in modern geography. It contains two articles related to the most traditional geographical techniques: geodesy, topography, mapping, and atlas production. The other three articles present modern techniques now very widely used by geographers: remote sensing, geographical information systems, and modeling."
