Lookup Table

What is it?

This window provides a lookup table to link landuse/landcover or soil classes to parameter values. By default landuse land cover values are pulled from the USGS landuse land cover dataset (2006) , and soil parameters are pulled from the USDA Soil Classification Guide .

Additional templates are available in the drop-down menu at the bottom-right of the interface:
1 - USGS 2006 (default template, used with DataCenter raster option)
2 - NLCD (National Land Cover Database) - US only
3 - GLC (Global Land Cover) dataset
Note: If the 'HSA Geoserver' option is used, template 2 or 3 should be used accordingly.

How to use it:

The user has full control over parameter values related to relevant soil and land classes in the model.
1) Parameter values can be edited by changing table values and clicking "Save Edits".
2) Unused classes can be removed by selecting a row and clicking "Delete Selected".
3) New classes can be added by clicking "Add Row" and entering column values (note, names must match the raster used).
4) The table can be saved, "Save File", for later use, or a previously created table can be loaded by clicking "Load File".
5) Changes won't be applied to the model unless "Save Edits" is clicked. Alternatively, edits can be discarded by clicking "Cancel Edits".
