The Export WAsP MAP File command allows the user to export loaded line and area features to a WAsP MAP format file for use with the WAsP (Wind Analysis and Application Program) application.
Only those line features with an elevation and/or valid roughness attributes will be exported. Only those area features with valid roughness attributes will be exported. Valid roughness attributes consist of a ROUGH_L and a ROUGH_R attribute containing numeric values for the left and right roughness for the feature. If neither of those attributes exist but a RV, ROUGHNESS, or ROUGH attribute is available, that value will be used for both the left and right roughness for that feature.
When selected, the command displays the WAsP MAP Export Options dialog which allows the user to setup the export. The dialog consists of an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.
