Roughness map

[Pedro Quiroga]

Hi support team
I´m working on a site validation and I'm having problems with the roughness map, so far I've read that there is some options to obtain the land use map, the first one is the GWA database, the second one is digitizing the lines in google earth or WAsP map editor.
I tried downloading the NASA LPDAAC > MODIS Land Cover dataset then I saved this file as Surfer Grid (.grd) and load in WAsP map editor but I'm having values greater than 100.
I'm using the wrong database? Isn't it the right procedure?
There is another alternative to obtain this map?
Thanks in advance

Hi Pedro,

Please have a look in the WAsP Map Editor's help file regarding "Digital Map Databases" and "Database-Map-Importer".

Best regards,

Brian
