Hi guys, Thanks for the great discussion. I am a bit confused regarding the address for the wms service.
You mention that The Toporama server is accessed at "http://wms.sst- sw.rncan.gc.ca/wms/toporama_en". However on the Geogratis Toporama site (http://www.geogratis.gc.ca/ geogratis/en/service/toporama.html), the address is "http://wms.ess- ws.nrcan.gc.ca/wms/toporama_en". I couldn't find the server address you mentioned in any Toporama info. One french site mentions it: (http://lac-conakry.blogspot.com/ 2009/05/besoin-de-donnees-geospatiales-pour-le.html) Your maps load pretty smoothly. Is there a preference which address to use? Is yours more up-to-date? Cheers yasha On Sep 7, 4:35 am, PierreB <[email protected]> wrote: > Papa Bear mentionned last week that canadian topo maps (NRCAN) are of > poor quality. This is true.
