WMS:GSSHA Continuous Maps

From XMS Wiki - http://wikis.aquaveo.com/xms/

Some GSSHA input parameters change from cell to cell and cannot be characterized using index maps. Continuous maps, which are stored as data sets of a 2D grid in WMS, are used where index maps are not appropriate. Examples of GSSHA input parameters that use continuous maps include soil properties for the groundwater processes and ground surface, bedrock, and water table elevations. Contours for each of the continuous maps are displayed on the 2D grid according to the contour options selected for the data set. Continuous maps are specified as GSSHA input in either the Sub-surface Parameters (Groundwater) dialog or in the Continuous Maps tab of the GSSHA Map Table Editor dialog.

The Continuous - Grid tab of the GSSHA Maps dialog has three options for generating continuous maps:

• Using GIS Data: Select an input coverage and attribute. Enter a name for the continuous map in the data set name field. Click the GIS Data -> Data Set button to create the data set.
• Using the Data Calculator: This option is useful for mathematically manipulating existing continuous maps.
• Reclassification: Reclassify index map values to create a continuous map, if appropriate.
