Hello community, Is it possible to use a (python) program as data source.
I will explain a bit: I do sensor measurements (temperature) at several locations in a country. These are displayed on the web with OpenLayers by sending them as points (with a list of all measurements done in a time interval (x, y)). It would be nice if these can also be displayed as a raster with (interpolated if needed) measurements for timestamp X. I considered the following approaches for this: 1. Create an OpenLayers vector 'grid' (a layer with a lot of vector rectangles), and give them appropriate colors. This however may be a very time consuming job for the browser, and the result can not be stored. 2. Generate a GeoTiff with python and gdal, and add it as a new data source to the map However, since the region is quite large, and there are a lot of zoomlevels involved, it would take a long time (generate the GTiff at a high resolution, processing with Geoserver, sending it to the browser). 3. So my next idea was: give (pass) the python gtiff generator the WMS request parameters, so it does not have to calculate a complete gtiff, but only the 'needed' part. For example calling: "python gtifprep.py --width=... --height=... --bbox=...." I hope #3 can be done by GeoServer (currently some DEM maps are also displayed with it). If it's not possible, what would we be the best approach then? Is there a WMS server/script which can call the gtiff creation by parameters sent by OpenLayers? Hope there can provide me with an answer? Thanks in advance.
