Download DEM and Build Terrain Mesh

Download the DEM data and build the terrain mesh (Allow administrator access for Rhino; Wait until the download to be completed in the background and re-enable this component to see the changes)

Inputs

  • Left []
    Left Bound (Longitude, x-axis) of the site
  • Right Bound (Longitude, x-axis) of the site
  • Top []
    Top Bound (Latitude, y-axis) of the site
  • Bottom []
    Bottom Bound (Latitude, y-axis) of the site
  • UTM []
    UTM Zone of the given region (can be used along with translation vector) to transform data from different sources to a common origin)
  • Vec []
    Translation vector to move from actual UTM window to working origin (can be used to transform data from different sources to a common origin)
  • X Count []
    Count of mesh vertices on X axis
  • Y Count []
    Count of mesh vertices on Y axis

Outputs

  • mesh
    Terrain mesh constructed based on the DEM data (data resource: https://dds.cr.usgs.gov/srtm/version2_1/SRTM3/)
  • UTM
    UTM Zone of the given region (can be used along with translation vector) to transform data from different sources to a common origin)
  • Vec
    Translation vector to move from actual UTM window to working origin (can be used to transform data from different sources to a common origin)
