Thank you Pierre It happens I have climbed Marble Mountain, an beautiful peak on the boundary, so it's nice to see it on your map.
Looking at the differences in approach, I see two things: 1) I use a variable tile size: US: topos: 400, NRCan raster: 600. NRCan vextor: 256. This may affect the efficiency of downloading, I would need to test to understand this better. 2) The choice of putting several parameters such as "Layer" as part of the original baseURL, or to put it in the function return WMSGetTileUrl)(). It doesn't matter in the end, but I would probably like to keep parameters which differ in the originally specified baseURL, so that the WMSGetTileUrl() is generic. For example at the moment, every service is set "VERSION=1.1.1", which is probably wrong (although it may not matter), in tyhe case 'f "LAYER=xxx" it's an extra function argument which could just as well be put as part of the original baseUrl. Incidentally, I expect to leave the NRCan Raster type on my maps, since they give a good rendition at wide zoom levels (small value of Google Maps zoom), whereas the vector data is much better at closer zoom but does not have any tiles at wide zooms. So I will use both. It would be nice to switch dynamically between the two, but I don't know how to do that. For the USGS maps, the Terraserver will choose which original map tiles to use (1:24,000, 1:100,000, and 1:250,000) and returns the appropriate tile automatically. I will do some more testing and tweaking and post another version. On Sep 9, 4:39 pm, PierreB <[email protected]> wrote: > My test was wrong since I pointed to my own WMSGetTileUrl function.
