WAsP – the Wind Atlas Analysis and Application Program |
WAsP uses digital maps to get information on terrain features: elevation and surface roughness (water / farm land / forests / built-up areas).
A number of vector map formats may be used:
|
Map-type |
Description |
Access |
| WAsP map format | Native WAsP map format; ASCII and Binary variants | Direct |
| DXF format | Autocad graphical exchange format | Direct |
| BNA map format | Boundary Atlas format of Didger and Surfer (Golden Software) | Direct |
| NTF maps | Maps in the NTF-format of UK and Irish Ordnance survey | Convertible by Map Editor |
| USGS Coastline maps | Coastline maps distributed by the US Geological Survey | Convertible by Map Editor |
The WAsP Map Editor is a special utility program, included in the WAsP package, with which one may create, read, edit and type-convert digital maps. Through a configurable import facility the Map Editor is also able to import a number of other vector map types and to convert them to the standard WAsP map format.
Maps in raster or grid format are presently not supported by WAsP, but may be converted to contour/vector format, e.g. by the Surfer program (by Golden Software).
Vector map format: Map consisting of height contour curves and boundary curves indicating a change in terrain roughnesses from one area to another.
Raster or grid map: A map consisting of a list of elevation values,one value foreach point in a regular grid; and correspondingly the terrain roughness.
