To interpolate elevation data to a geometry using multiple elevation sources, do the following:

1. Import elevation sources.
1. Import rasters.
Raster data is imported into the GIS module in SMS.
  1. Use the Open command to import raster data files such as DEMs, KMZ files, and gridded elevation formats.
  2. Files can also be imported with the "drag and drop" option.
2. Import other GIS data.
  1. Use the File | Open... command to import GIS data files such as Shapefiles, MIF/MID files, Lidar files, or raster files.
  2. Alternatively, drag and drop the file into the Graphics Window in SMS.
3. Import Scatter Data.
  1. Use File | Open... to open files with scatter data such as scatter point files, ASCII dataset files, binary dataset files, tabular data files, or XYZ files.
  2. Alternatively, drag and drop the file into the Graphics Window in SMS.
  3. Use the File Import Wizard to specify how to import the data.
4. Import Online Data.
1. Import static images.
  1. Use the File | Import from Web command.
  2. Select a location in the Virtual Map Locator.
  3. Set a projection for the project using the Display Projections dialog.
  4. Use the Data Service Options dialog to select a web service or catalog.
    • Use the Advanced options if needing to access a unique or unavailable data source.
  5. Save the data file and import the data into SMS.
2. Import dynamic images.
  1. Use the File | Add Online Maps command.
  2. Select a location in the Virtual Map Locator.
  3. Set a projection for the project using the Display Projections dialog.
  4. Use the Data Service Options dialog to select a web service or catalog.
  5. Save the data file and import the data into SMS.
2. Clean up rasters using the tools for rasters in the toolbox.
Possibly useful tools include Blend Raster to Edges and Clip Raster from Elevation.
3. Interpolate raster elevation to geometry to create new elevation dataset.
The Interpolate Priority Rasters tool allows for multiple rasters to be used when interpolating onto a geometry. To do so, follow these steps:
1. Use the Interpolate Priority Rasters tool to interpolate raster data onto the desired geometry.
  1. From the Toolbox, select Interpolate Priority Rasters
  2. Select the geometry to interpolate onto.
  3. Select the order of priority for the rasters that will be used for interpolation. The order determines which raster the program will look at first to interpolate data onto the geometry.
  4. Run the Interpolate Priority Rasters tool.
2. Review the data on the geometry.
  1. Turn off all rasters.
  2. Turn on the desired geometry.
  3. Adjust the Display Options Display Options Macro.svg.
4. Set the map elevation dataset to the newly created dataset.
  1. While in the appropriate module for the geometry, use the Data|Map elevation... command.
  2. Select the newly created dataset.
  3. Adjust the display as desired to review the change in mapped dataset.
