Sol Open Topography Walk Through

Sol Open Topography Walk Through

To test out the Opal2 Web Service I did a simple walk through from the OpenTopography steps:

  • Log into the MyOpenTopo tab on the top left if you have a Username set up:
  • Navigate using the Data tab to the area you want to sample.
  • Select a bounding box and the types of outputs you want to generate (e.g. TauDEM hydrologically corrected DEMs)

  • These data will remain available for about 7 days - after which you can re-process the job at any time using the metadata tag.

http://ot-data1.sdsc.edu/appRasterSelectService1457023481613-1049895410/rasters_srtm.tar.gz
  • Next, I insert the URL into the Opal2 service provided box for Input DEM URL:
  • The Web browser is designed to unpack the *.tar.gz file and begin running the Sol program.
  • After you submit the process you should see something like this:
