Ruggedness of a site

[dcarvalho]

Hello to all,

I really need to obtain the ruggedness value (m) of a site. But, when I click on the site in WAsP project, I can only get the RIX and delta-RIX. I also get the ruggedness but by sector.

Can someone help me, in order for me to get the ruggedness value of that site?

Thank you

I guess you are thinking about the "roughness value" or "roughness length / height" around a site. This is changing around the site, depending on the land cover. You may be able to specify a single, typical value for sites in very uniform terrain. In the 'Site effects' window, you can see a reference roughness for each sector, but WAsP will not give you an overall (omni-directional) roughness length for any site.
