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.

In the world of remote sensing and geospatial analysis, few software suites command the respect and longevity of ERDAS IMAGINE . Developed by Hexagon Geospatial, ERDAS (which originally stood for Earth Resources Data Analysis System ) has been a cornerstone for photogrammetry, LiDAR analysis, and advanced image processing for over 40 years. If you need survey-grade accuracy for engineering or

For true photogrammetrists, no other software offers the same smooth 3D stereo cursor experience for digitizing features directly from overlapping aerial photos. ERDAS’s sensor models (RPC
