We have an internal PostGIS/Geoserver for rendering map tiles for the world based on OpenStreetMaps. We would like to overlay weather, but would like to do so without referencing external URLs. The weather data at this URL (http://radar.weather.gov/ridge/RadarImg/NCR/) uses a gif/gfw format, but I am so new to GIS that I am not familiar with how I can take advantage of these for our use.

Does anyone know of any documentation on how to get weather layers in PostGIS/Geoserver, or even better, using the gif/gfw format from above?

  • for historical data yes, for up-to-the-minute no, with MaryBeth a webservice would be a better way to do this. – Mapperz Nov 13 '15 at 15:37
  • do you have your own weather station? – Mapperz Nov 13 '15 at 15:38
  • There is lots computations for Weather see the Weather Research and Forecasting Model WRF www2.mmm.ucar.edu/wrf/users/model.html for an understanding – Mapperz Nov 13 '15 at 15:43
  • No, we do not have our own weather station. – Matt Nov 13 '15 at 18:48

If you want to avoid external urls in your map application you could use geoserver to cascade the external weather maps to your app, then you can use your cache etc.

  • I did not know about this, I will look in to it, thanks! – Matt Nov 13 '15 at 19:07

I would avoid using a gif for weather data--as that would be a static file and you would have to update your gif constantly. A webservice would be a much better choice to dynamically display data.

NOAA and NWS both have data sets for this.
