Hi! I've been trying to create a roughness map using the WAsP scripting plug-in for QGIS (it used to work perfectly) and I keep getting this error message when getting the CORINE landcover polygons: Querying the URL 'https://api.globalwindatlas.info/qgis-data/v1/corine_2018?points_str=-4.915092816615868,42.65048975312536;-4.914362396203785,42.64997445201428;-4.901231231263719,42.21718162357918;-4.90192475126123,42.21664257303623;-5.48401315512234,42.20550918092915;-5.4847427626322895,42.206020900137226;-5.501895032585442,42.638644324206716;-5.50120232641207,42.63918695661474;-4.915092816615868,42.65048975312536' did not return a valid GeoJSON object! I think it's related to the API but I've no idea how to fix it. Any suggestions, please? Thank you in advance, Lidia:)

The standard way to generate an observed mean wind climate file is to use the WAsP Climate Analyst tool. By default, this program will export to the OMWC file format, but you can also select the old TAB file format. To write a TAB file without the Climate Analyst, you will need to check the format in the WAsP help file section Technical reference>WAsP file formats>Observed wind climate>Observed wind climate (*.tab)

Hi, The GWA and NEWA servers are currently down due to a file system issue. Our team is working diligently to resolve this and restore service as soon as possible. Unfortunately, we don’t have any updates at the moment. Please refer to our webpage for the latest information, as we are currently handling a high volume of inquiries. Alternatively, you can download GIS data from the following sources: https://globalwindatlas.info/en/download/gis-files https://data.dtu.dk/articles/dataset/Global_Wind_Atlas_v3/9420803 Thank you for your patience. Best regards, Joan

I have been trying to download micro and meso data from the API, but it hasn't been working since Thursday. Do you know what the issue might be?

that's helpful, however, i would like to know how to properally format data from vortex to match the .tab observed wind data on WaSP as it keeps showing error when i insert the file

hi this is my firs time working with WaSp, I am trying to insert data from vortex which i chnaged from .txt to .tab but there might a problem with the formatting file that I am not aware of as the doftware keeps showing error in line #3 which is the line for the number of sector rose. i put it as 12 Location: 5000 11400 Height: 80.0 12 6 0 2 4 6 8 10 15 regards

Dear Yasir, Could you please provide us with more details about your project and share the project file? This will help us assist you more effectively. Looking forward to your response. Best regards, Joan

Here’s your question, rewritten in a clear and professional manner for posting in the WAsP forum: Hello, I am new to WAsP and currently following the step-by-step Serra Santa Luzia tutorial provided in the help section. While I have been able to follow the instructions successfully so far, I am encountering an issue when reaching the step for "adding a site description." The software does not automatically read the location as described in the tutorial. Additionally, the symbol for my Generalized Wind Climate (GWC) in the hierarchy list is represented in red instead of yellow (as shown in the tutorial). I suspect this might be related to either the GWC or the map file, but I am not sure how to resolve it. I would greatly appreciate any guidance on what might be causing this issue and how to fix it. Thank you in advance for your help!

Dear Petar, Could you kindly submit your inquiry through DTU Learn? Thank you. Best regards, Joan

Hello, Is it possible to get some assistance with WASP case study? Thanks! Petar

Sure, everything is possible. I have reached out to via DM to see if this is something we could collaborate on.

Let's say you have 100TB of data. You split it into 1000 geographical tiles and then compress it and put it into a torrent. Downloading 10GB is manageable on todays broadband connections.

You could split the timeseries data into geographical tiles. Torrenting is a very good way to share big files too.

Thank you for your suggestion, we have not seen academic torrents before. However, I am not sure that it would be a good set for the New European Wind Atlas dataset. Our dataset would almost double the amount of data available via that platform. It is also unclear to me how users would be able to subset the data so they could get what they are interested in and not the full dataset. We are almost finished repackaging the data into a format that should allow users to download around 10 years of data for a single point. We are doing performance testing to determine the new limits for this repackaged data. It should launch early next year.

Are you still having this issue? I am not able to replicate it. If I select say downloading 2005-01-01 for Wind Speed at a point near Copenhagen, I get the NetCDF file for that point.

Support is telling me that i shouldn't request data longer than 6 months. This is obviously useless. Everybody wants long term data. Pls put the whole archive online through torrents. https://academictorrents.com/ Like so.

Yes, in Brazil we sometimes need to. It's an unusual situation, but in some projects we have very large areas available for projects. I've even tried joining two shapefiles downloaded via wordcover, but they don't fit together perfectly

Yes, there was recently another case that had this problem. The solution there was like this:

Hello and thank you for this great plugin. I am using the plugin and for the CORINE dataset, I don't have any problems. However, when I use WorldCover, I receive the following error.

There is ways to do that, but I guess the first question is whether you really need a map this big? Usually a distance of about 20 km from yours turbines/mast is more than enough and anything more will not have a significant effect on the flow modelling results, but will make the computations significantly slower.

I see a mail address in your profile and will use that for continued discussion.

Hi Morten, Thanks for picking this up. I have engaged with our IT team, and they arrived at the same conclusion as yourself. They have identified several IP's that have been blocked when making the access request, and have asked if you can confirm which of them relates to WAsP so that they can whitelist them. Are you able to pick this up in a private channel so that I'm not broadcasting IP addresses? Thanks

Hello, I am currently trying to use the 'DTU Wind' tool for QGIS to create a roughness map for an area larger than 60 x 60 km, which is the area limit for the "Get WorldCover landcover polygons" tool. Is there a way to divide a larger area into sub-areas and merge the .map files?
