Re: [udig-devel] Setting a CRS for a layer or for the whole map

[George Schole <georgeschole@xxxxxxxxx>]

"Hi, the error you get seems to refer to the fact that within the same layer you have objects with different crs" - But i get this same error message even  if i add only the Mapnik wmt layer. And i am sure that there are no other resources/layers added . I have also now tested this scenario  in udigGIS: added postgis layer-> added wmt layer-> clicked on the "zoom to are of interest" tool's icon. Everything works fine... Quite weird. I will further investigate this problem. Meanwhile any ideas/suggestions that may help solve this problem are welcome.
Cheers

Hi, the error you get seems to refer to the fact that within the same layer you have objects with different crs, which uDig can't handle. 

Layers are reprojected, if the objects contained are all of the CRS.

I think there is something going on in the feature creation of your.

Hi,

How can I set the projection of a layer at creation? How ca I set the projection for the whole map? Is there any better solution?

Judging by the error I get,it seems that when a layer is added to a map it is not automatically converted to a common crs.

In my particular case I have modified preferredzoomlevels tutorial so that I may see a postgis layer and a wmt layer (openstreetmaps) instead of a shp .

The error I get when I try to “zoom to area of interest” :
