I've just spent the last 4 days getting a handle on using OpenLayers (and
learning a LOT about GIS in general) - so to all the Developers out there a
hearty - Well done - your ROCK!
I am stuck on my final step of implementing this for several web sites and
would appreciate any advice those in "the know" can offer:
1) I need to find the best way to add a JPEG map (produced elsewhere) that
is NOT georeferenced yet to be an overlay layer for OpenLayers - hopefully
via TMS as the map is street level of a region. I expect that I need to:
a) Georeference it (best way to do that? I have many known LatLon points on
the map)
b) Save it in a friendly format (gtiff ?)
c) Tile it (tried gdal2tiles - but not sure how to control the output
resolutions to match my base layer VMAP0)
d) Upload it to the web server as a TMS (I want to be able to serve it
WITHOUT Mapserver)
I have gone ahead and installed MapServer 5 on my dev server in the hopes I
could add it that way (via a WMS layer and then pull off the tiles) but I
still need to georeference it and Find the extents (no idea how to do this
for a raster gdalinfo doesn't seem to give them the way orginfo does and
everything online seems to be about the later)
I have access to QGIS, ArcView, MapServer, FWTools, and extensive PHP
programming knowledge
I tried for about half a day to get TileCache to work (having read that is a
good way to do the tiling) but my web server really doesn't seem to like
Python so I'm hoping there is some other way.
Any advice much appreciated - I can make several people very happy if I can
get this working.
