私はArcGIS Onlineでリアルタイムの天気マップを作成しています。NOAAから気象観測所のデータを取得しており、観測所での気温を得ています。私の目標は、ポイント間のデータを補間し、ユーザーが自分の家をクリックすると、その場所での推定（補間された）気温を表示するポップアップダイアログが表示されるようにすることです。何かアイデアはありますか？<\/P><\/BODY><\/HTML>
Thank you, but unfortunately I do not have access to my organization's web server to do the file conversion. I found a custom widget that should work out fine. Thank you again for your suggestions.
The link to the data is here: NCEP Data Products RTMA/URMA, you'll also need to convert from grib2 -> raster format such as NetCDF.
I have something similar that I wish I could use, but it is a map image layer. Therefore, it does not allow for a pop-up box when the map is clicked, which is what I want. I looked at the link you provided and did not see a way to access the data other than on their webpage.
Why not just use the Real Time Mesoscale analysis gridded dataset from NOAA and not worry about the issues you typically encounter with different interpolation schemes and deficiencies that might be present due to the sparsity or uneven distribution of observations?
