Hi,

  Is there any way to save georeferenced TIF raster images from a WMS server? I'm in British Columbia, Canada. I use Manifold for most of my GIS work and also use qGIS. I'm looking for a way to add contour lines as a background. The government of BC offers a WMS server with the contours in a selection of projections. The problem is Manifold can't retrieve WMS layers. It connects but lacks the ability to select among the projections offered and just defaults to the first projection offered on the provincial servers which is geographic (lats & longs). I wrote to manifold and the ability to select a projection is a "feature". I submitted a feature request years ago. Also for some reason contours render as one giant purple square so I can't even use the lat/long projection. I have map layouts in Manifold and I'm also using Manifold thematic shading in legends. I'm reluctant to re-set them up in print composer in qGIS. 

 

 On the other hand qGIS connects nicely to the provincial WMS layers. But I can't export a georeferenced image for import to Manifold. I've spent several days searching or a way to save a contour line basemap from the url http://openmaps.gov....s&version=1.1.1  from the geodata site http://www.data.gov....nect/index.page  The WMS layer ID I'm after is #179 TCTR_Lines Evelation - Contours (1:20K)  and the contour labels which is ID #55 TCTR_ANNO (Elevation - Text (1:20K).

 

  I have a relate question and I'll post separate a message asking how ERSI users have contour lines as their basemap. That's the effect I need to duplicate. The best I can do now is use hillshades but I need contours with elevations. I can buy the data from the province but they are $5,000 per unit and out of the question.

 

thanks

-Tony

Hi

An update to using BC provincial WMS layers in Manifold 8 when Manifold can only bring tiles in using the first projection offered by the WMS which on the provincial servers is lats and long. Folks on Manifold's forum guided me to set up GeoServer as an intermediary map server. GeoServer can bring in WMS tiles using any of the projections offered by the WMS. See the description here http://www.georefere...orum/t122516.18    GeoServer acts as an intermediary bringing in a WMS tile in one coordinate system and serving it up to Manifold in another. In my case in by UTM9, out reprojected to BC Albers. Brilliant. I run GeoServer on my workstation all the time with no noticeable impact on CPU or memory.
