Description

Load a layer (e.g. alaska.shp from the sample data set). Turn on OTF transformation and choose NAD27 as the target coordinate system. Once set, click on Zoom full or zoom to layer extent. It doesn't work. Using the zoom to point plugin and putting -150, 60 and zooming shows the data is there and reprojected to NAD27 geographic.

This problem has been confirmed in HEAD on Windows, Mac, and Ubuntu.

Are you sure that worked with 1.6? landice works, alaska or airports does not. Looks like it's a problem with extents crossing the dateline. I think we don't have a way to express that a bounding box for a latlong crs is including the dateline instead of excluding it.

Yes, I'm sure. It works on both 1.5 and 1.6 on OS X. It also works on 1.6 on Windows with the standalone installer. I don't have earlier versions for other platforms to test.

This problem was introduced by which fixed issue #3471.

#4 Updated by Gary Sherman over 13 years ago

The change in may not be the root cause. Projection is not getting set when loading a layer (e.g. from the alaska sample set). If you load the layer, set the projection to Alaska Albers NAD27 then reproject to geographic the zoom full works.

Ignore my last comment about projection not getting set. Must have been an anomaly--- is the cause and there must be away to deal with projections that span 180 degrees while still fixing issue #3471.
