ASTER Data and WindFarmer Import

[ichadtanguilig]

Hi,

I would just like to ask how do you convert ASTER GDEM maps into WAsP map? Also, I've been trying to import .map files to Windfarmer but it is not working. Already used the ASCii .map option. Thank you.

Hi, "ichadtanguilig" (what ever that means?) - unfortunately the WAsP suite does not support all digital map formats, in this case the Aster GDEM. But - as an alternative - the Map Editor may import SRTM maps (version2, 3-arc-sec resolution; up to 60 deg. North).
For Aster GDEM We could suggest to use a) Global Mapper to convert to WAsP .map, or b) Surfer: here should google for "Aster GDEM to Surfer" to find a solution to make Surfer read Aster GDEM, since Surfer cannot do it directly; afterwards have Surfer export the map-contours as a DXF-file, which the Map Editor may then read - and then save as .map. Both Global Mapper and Surfer are commercial products. Finally we could suggest to try the free-wares c) SAGA GIS and d) QGIS: they may be able to read GDEM and convert directly to .map or another vector format which may be imported by the Map Editor, and then saved as .map.
Regarding .map and Wind Farmer: you will have to contact the Wind Farmer people directly. The .map format is well described in the WAsP Map Editor - so it should be straight-forward to check whether Windfarmer can accept that.

Thank you very much, Ole. I just used the SRTM map avaialble for download via the Map Editor. :)

However, I have a more detailed map (1m contour) of the wind farm area and would like to extend it using the SRTM or ASTER data. Would it be possible for Map Editor to do that?
