Introduction to LPS

LPSIn this intermediate, application-oriented course, students will learn the tools and functionality necessary to complete a desktop mapping project, using ERDAS'  LPS. Instructors will explain how to triangulate a block of images, extract elevation data, and create orthorectified imagery. Data sources used include conventional aerial photographic frames and QuickBird imagery from DigitalGlobe. (3 day class)



Learn To:

  • Understand basic digital photogrammetric theory needed to use LPS
  • Input all necessary data, create and triangulate blocks of imagery
  • Use the Automatic Point Measurement tool to improve triangulation results
  • Extract elevation data to produce a Digital Terrain Model using tools in LPS
  • Display, edit, and enhance Digital Elevation Models using standard ERDAS IMAGINEĀ® tools
  • Orthorectify multiple images from a block using elevation data from multiple sources
  • Mosaic several orthorectified images
  • Visualize orthorectified imagery in a standard ERDAS IMAGINE Viewer and use the Image Drape tool to create perspective three-dimensional scenes
