WIGeoATP was developed by WIGeoGIS as an additional feature for WIGeo QGIS. QGIS is an open source GIS software, meaning you can use it without any license fees. It is a desktop-based software that runs on Windows, Linux and other operating systems. So you first have to install WIGeo QGIS to use WIGeoATP. This provides you with a whole portfolio of other useful geomarketing features. We are happy to advise you.
