#608: GIS.m: Lat/Lon support broken in Map Display zooms -----------------------+---------------------------------------------------- Reporter: hamish | Owner: [email protected] Type: defect | Status: new Priority: blocker | Milestone: 6.4.0 Component: Tcl | Version: 6.4.0 RCs Keywords: gis.m, LL | Platform: All Cpu: All | -----------------------+---------------------------------------------------- Hi,
when in a lat/lon location the gis.m Map Display zooming is quite broken. Previously you'd get many "Error setting region: child process exited abnormally [ok]" popping up*, and if you zoom out to the global scale everything pretty much goes haywire. [*] because `g.region n=$mapcanvas_value>90` there's a partial fix in SVN now (r37285) -- it will switch into constrained mode if you try to zoom out beyond 90 degrees N,S. But it's not quite right, you still get white borders and the canvas coords get all messed up after that. I expect that besides switching to constrained mode it needs to either recalc the resolution after resetting N,S to 90, or just break out of the routine it's in because the premise for being there becomes invalid. I've taken it about as far as I can go. ??? Hamish -- Ticket URL: <https://trac.osgeo.org/grass/ticket/608> GRASS GIS <http://grass.osgeo.org>
