About Us


Developing reasonably priced, highly functional software for the GIS professionals is the prime objective of ET SpatialTechniques. ET GeoWizards for ArcGIS was first released in 2002 followed by ET GeoTools (2004) and ET Surface (2008). All 3 products were extensions for ArcGIS and became the most popular third party data processing extensions for ArcGIS.

ET GeoWizards 12.x and ET Surface 7.x are the future of our products. They can be used by all GIS professionals - no matter what their main GIS platform is, but at the same time they are seamlesly integrated in ArcGIS Desktop and ArcGIS Pro.
