I have tiled maps generated by gdal2tile.py which load into OpenLayers very nicely using units:'pixel'. I would like to change the layout to lat/lon and am having trouble, and request assistance (I've flailed around with various options settings, but really don't know what I'm doing).
Q1) The reason for doing this is to (hopefully) be able to overlay nexrad weather by referencing a layer from http://columbo.nrlssc.navy.mil/ogcwms/servlet/WMSServlet/AccuWeather_Maps.wms Is this timely data? How often is this data refreshed? Is there a better source for nexrad data? Q2) I assume that I need to change from pixel-units to lat/lon-units in order to layer the AccuWeather_Maps on the display, correct? Q3) Is gdal2tile.py still used in OL 2.6 (it seemed to be based on 2.4), or is there a better way to have OpenLayers generate the tiles? Does it pre-generate them, or do it on-the-fly? Q4) Do I need to fully understand all of the extents vs. resoultion vs. maxResolution etc, or is there an easy way to capture the gdalinfo data from a GeoTiff file and import that into the options array needed by OpenLayers? I think OpenLayers is a terrific tool, I'm just not a cartographer (yet).
