Description

QGIS SVN 6248:

1. added few shapefiles of unknown projection

2. set the projection to EPSG:4179, enabled on the fly

3. added a raster of a different projection, namely:

Driver: GTiff/GeoTIFF
Size is 3800, 2500
Coordinate System is:
PROJCS["TNTmips Georeference",
    GEOGCS["WGS 84",
        DATUM["WGS_1984",
            SPHEROID["WGS 84",6378137,298.2572235629972,
                AUTHORITY[[EPSG""7030]],
            AUTHORITY[[EPSG""6326]],
        PRIMEM[[Greenwich]],
        UNIT[[degree]],
        AUTHORITY[[EPSG""4326]],
    PROJECTION[[Transverse_Mercator]],
    PARAMETER[[latitude_of_origin]],
    PARAMETER[[central_meridian]],
    PARAMETER[[scale_factor]],
    PARAMETER[[false_easting]],
    PARAMETER[[false_northing]],
    UNIT["metre",1,
        AUTHORITY[[EPSG""9001]]

4. zoom to raster -> crash; the bt:

I know the projection I declared and raster's projection don't match, but this I learned in the process and QGIS shouldn't crash in the first place.

#1 Updated by Magnus Homann almost 18 years ago

Is it possible to attach raster and/or the dataset?

#2 Updated by Redmine Admin almost 18 years ago

Replying to [comment:1 homann]:

Is it possible to attach raster and/or the dataset?

Sorry I don't have it anymore. And I can't reproduce with other dataset at will. The procedure in general should be:

1. add a shapfile without *.prj

2. set some projection, enable on the fly

3. add a GeoTIFF with a projection different than set in step 2.

4. zoom to raster -> crash

#3 Updated by Gary Sherman almost 18 years ago

this can be duplicated by loading any shapefile with a projection different from the raster, setting the projection to a third projection, then adding the raster.

Zoom to raster causes crash.

#4 Updated by anonymous - almost 18 years ago

Partial fix in svn 546b8e21 (SVN r6342). Qgis shouldn't crash now, but it doesn't quite yet zoom to layer extent correctly for all combinations. Note that the zoom to layer extent button in the toolbar does work correctly - the zoom to layer in the legend is the problem

#5 Updated by Gavin Macaulay - almost 18 years ago

  • Status changed from Open to Closed
  • Resolution set to fixed

Fixed in svn c226ee18 (SVN r6346). No longer crashes. Better behaviour when projecting between incompatible coordinate systems could be an enhancement for later versions of qgis.
