GeoCounsel provides consulting and training services in geomatics, with emphasis in civil engineering
and geomatics (photogrammetry and geodesy).
To illustrate this, we have:
Geodesy provides the physics and math that are used to write the equations and define the variables needed to define positioning on earth in support of any GIS or map-managed project. It is the umbrella science that covers all physics and math related to the shape of the earth, ellipsoids, geoids, datums, projections, etc., and therefore impacts aerial and satellite mapping, GPS/GNSS, GIS, UAVs, and navigation. The word "geodesy" comes from the two Greek words "earth" and "dividing".
The word "Photogrammetry" also comes from the Greek, meaning "measuring what was drawn with light". It is part of geodesy, and covers aerial and satellite mapping using photography or imagery. It is the physical and mathematical basis for Google Earth, GIS images, and engineeirng and regional mapping. Photogrammetry provides the spatial geometries and math to calculate precise quantities from images, whether they are aerial or terrestrial photographs or satellite images of earth or other celestial bodies. Photogrammetry is uniquely capable of allowing the 3D reconstruction of spatial relationships and is the technology that was used by the USGS during the preparation of the quad sheets, and by NASA to map Mars, Jupiter, etc.
