DEM CuePac

The Digital Elevation Modeling (DEM) CuePac provides a range of functions for managing and processing elevation data within GeoCue. DEM CuePac is useful for a wide variety of tasks that require visualizing elevation coverages, merging and extracting elevation data and exporting those data in a variety of formats for downstream processing. A prime use for DEM CuePac is the visualization and preparation of elevation surfaces for orthorectification. When combined with GeoCue’s LIDAR 1 CuePac, LIDAR data can be directly converted into elevation sources suitable for orthorectification.

• LAS as a standard format
  The DEM CuePac uses the American Society for Photogrammetry and Remote Sensing (ASPRS) LAS point cloud format as a common manipulation standard within the DEM CuePac. Elevation sources of various formats can be imported into GeoCue, converted to LAS, processed and then converted to export format.
  
• Merge/Extract
  DEM CuePac provides features for merging multiple elevation models and for extracting from models.
  
• Advanced Geometric Constructions
  DEM CuePac provides functions for very rapidly creating specialized elevation models for orthorectification workflows, even when the rectification process is not GeoCue encapsulated.
  
• Full Horizontal and Vertical Transformation Support
  DEM CuePac provides complete support for both horizontal and vertical coordinate transformations.
  
• Quality Check/Quality Assurance
  DEM CuePac provides a number of tools for performing QA/QC tasks. Project-wide rendering of elevation “orthos” allows quick synoptic checking of data. In addition, DEM CuePac allows probing of elevation surfaces with control points for testing absolute accuracy.
  
• Special Image Rendering Tools
  DEM CuePac extends the GeoCue “LIDARgrammetry” concept to all elevation data. Simply import a source into DEM CuePac, create LAS Working Segments and generate synthetic stereo models. Use hybrid merged models to fill in detail. Currently supported stereo systems include BAE Socet Set®, DAT/EM and Intergraph SSK.
