To compute the rainfall depth on the sub-basins of your MODRAT model, you must read in a rainfall depth data layer. The isohyetal maps for LA County have been digitized and stored in ARC/INFO® Grid format by the LACDPW; these files can be found in the /MODRAT/Rain/ folder installed with WMS. Import this data by choosing Open from the File menu, then choose Rainfall Depth Grid (*.*) as the file type.
Alternatively, if you have other rainfall data in vector format (ArcView® Shapefiles, DXF, etc.) you can import these into WMS. Make sure that you create a Rainfall Coverage (see the Coverages dialog) and map the appropriate database fields when importing this data.
Once the rainfall depth data is present in WMS, you can compute and assign depths using the Compute GIS Attributes command from the Calculators menu.
