Other weather data sources #6

Hi Mostapha, This is very nice. As a wish: Maybe sometime in the future different weather data sources can be implemented? I know different applications (Autodesk's) use such sources. Maybe they are sintetically created or otherwise. But can be nice to have other sources, specially for places where official epws are scarce. Thanks, -A.

Hi Abraham, Thanks. It is possible and technically pretty easy. If you add related data to the weather file to this csv file (https://github.com/mostaphaRoudsari/epwmap/blob/gh-pages/data/epw_weather_data.csv) they will be automatically added to the map!

All you need is id, station-name, lat, lon, download_link. Pretty easy, right?

The main question is about licencing for sharing the data. If anyone (including Autodesk) owns some weather data which they want to share and be downloaded from epwmap it will take less than 15 minutes to add them all! ;)

Yes. Looks pretty easy to implement ... after you get the license or link. Do you happen to know what are the sources of Autodesk (Vasari/Revit)? I assume they didn't developed or collected the data, so where the hell they get it from? From all the times i asked and others i didn't succeed in understanding their answer :-( -A.

I don't know the answer to your question but I hope @tatlin know the answer to your life-time question. :)

tatlin commented 9 years ago

Autodesk has a web service called climate server that can give you weather files on an 11 km grid for most parts of the world. All you have to do is give a lat long.

Thanks @tatlin for the quick response.l I think @ayezioro is mainly concerned about the source of the weather data. Does Autodesk has their own stations? Is it generated based on algorithms similar to Meteonorm or is it something between the two? Am I right @ayezioro?

Thanks@tatlin for the answer. Yes, i meant what Mostapha said. I'm curious about the source of the data and its reliability. Giving that the data is good, now the question is if it can be used in Mostapha's project and/or downloaded. Another question is if this data can be accessed only by using Autodesk software or there are other ways to see and check the data? Thanks, -A.

We get this data from government and private sources around the world and use a computational model to create the more dense grid. More info is available here:

Thanks @tatlin!

Abraham, I'm closing the issue for now. Feel free to re-open if needed.
