Thanks Dane and Rob, I worked around the issue of loading cascadenik files from
windows by hosting them on a webserver. I am still having a bit of an issue
where the datasource I define in the mml file:
<Layer class="points" srs="+proj=latlong +ellps=WGS84 +datum=WGS84 +no_defs" >
<Datasource>
<CSSParameter name="type">SHAPE</CSSParameter>
<CSSParameter name="file">C:\Shapefiles\POINTS</CSSParameter>
</Datasource>
</Layer>
<Layer class="paths" srs="+proj=latlong +ellps=WGS84 +datum=WGS84 +no_defs"
>
<Datasource>
<CSSParameter name="type">SHAPE</CSSParameter>
<CSSParameter name="file">C:\Shapefiles\PATHS</CSSParameter>
</Datasource>
</Layer>
Is getting lost in the compilation and the created xml is:
<Layer name="layer 9" srs="+proj=latlong +ellps=WGS84 +datum=WGS84 +no_defs">
<StyleName>text style 7 (PT)</StyleName>
<StyleName>point style 8</StyleName>
</Layer>
<Layer name="layer 18" srs="+proj=latlong +ellps=WGS84 +datum=WGS84
+no_defs">
<StyleName>line style 13</StyleName>
</Layer>
It's not a big deal, but if someone knows why it'd save me a few minutes.
Well, I solved my original issue while writing this so I'll just write it up in
case someone else searches for something similar. I'm using google maps to
display the tiles created by TileCache against a map created by Mapnik from a
shapefile. Inspecting the shapefile and the end result map the lines all
looked
correct, but were shifted down in google maps a little bit. This was because
the srs in the mapnik xml was:
+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0
+units=m +nadgri...@null
but in the tilecache.cfg file it was:
+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0
+units=m +nadgri...@null +wktext +no_defs
updating the config file makes it all look nice.
Thanks again
Jeff
