Here's the setup: QGIS 1.9.0-master, running on Ubuntu 13.04 I have a two layers and with two different Custom CRS defined The basemap image and project use this one: +proj=eqc +lat_ts=0 +lat_0=0 +lon_0=0 +x_0=0 +y_0=0 +a=2440000 +b=2440000 +units=m +no_defs The other layer (a netCDF grid with data for -180/180/-90/90 uses this one: +proj=longlat +a=2440000 +b=2440000 +no_defs
Enable "on-the-fly" CRS is enabled.
Here's the problem: The second layer is incorrectly and unpredictably cropped at the edges. The features are positioned correctly, so it appears that the reprojection is correct, but the display of the layer is not. The attached image shows the problem.
Also: When I zoom in, the cropping changes. When I pan the map, the cropping again changes each time the map is redrawn. I was hoping that this would be resolved in the latest versions of QGIS, but as far as I can tell, this has been unresolved since version 1.7. This only seems to happen when using the +proj=longlat Custom CRS for a source layer.
Is there a solution or workaround?
