For true photogrammetrists, no other software offers the same smooth 3D stereo cursor experience for digitizing features directly from overlapping aerial photos.
If you need survey-grade accuracy for engineering or legal mapping, ERDAS’s sensor models (RPC, Rational Polynomial Coefficients) are mathematically superior to generic GIS warping tools. For true photogrammetrists, no other software offers the
But what exactly makes ERDAS the go-to solution for GIS professionals, and how does it differ from standard GIS tools like ArcGIS or QGIS? At its core, ERDAS IMAGINE is a remote sensing image processing software . While traditional GIS software focuses on vector data (points, lines, polygons) and basic raster display, ERDAS focuses on the pixel . For true photogrammetrists
