Analyze Menu

Until a DEM is loaded, only a few choices will be available on  this sub menu of the MICRODEM menu.

• Convert coordinates: convert between different datums, with lat/long, UTM, and MGRS coordinates.
• Computations
• Geocode, address to lat/long
• Sunrise-sunset tables or graphs, with algorithm from Naval Observatory.
• Moonrise/moonset: calculate moonrise and moonset (plus sunrise/sunset)
• Algorithms
• DEM Properties
• Header view header record for the DEM or image. You can verify that the datum is set correctly.
• File Metadata. Opens popup menu, select data type, pick file, and see metadata.
• Create
  • New global grid, Greenwich
  • New global grid, IDL
  • Landsat browse index
  • Landsat full scene index

• Geomorphometry analysis  (requires geomorphometry menu option set)
• Cluster grids (unsupervised classification): done with all open DEMs
• Trim deviations: remove points from the original DEM that are outside a specified deviation from the trend surface
• Correlation Matrix
• Distance matrix 
• Satellite predictions
• Spectral library

These options may not be available, and may not work even if they are available.  They were developed for specific research projects, and some of the project flow may have been hard wired in the code.

• Batch processing--some of these can use multiple processors/cores, and operate on global data sets
  • Geomorph atlas
    • Block statistics for series from the map library.  Landform wavelength/height can be done as part of this computation.  Uses threads for multiple processors.  Pick the DEM series to use, and the output directory for the DBF files.  Because of the threading, each DEM will have its results put into a separate DBF file which can be combined in another step.
    • Merge block statistics DBFs.  For SRTM-3", this will combine the dBase tables created by the block statistics options into global grids. 
  • Lidar and global DEMs
  • Create DEMs from lidar
  • Categories from all open DEMs
  • Categories from data base
  • Subsample compare thin/average
  • ACOLITE
  • DEMIX
  • Time cores
