HI there QGIS 2.14.1 Ubuntu 15.10 - 64 bits In designer, when I try to change the width of one map through properties, QGIS freezes. It happens if i select the current value in the "width" box of "position and size" and try to overwrite it with another value, typing it. If I change the size by

Hi Nicolas, That is not exactly true. QGIS can very well cope with grid-shift based transformations. This requires an adequate grid shift file (a gsb file), which should be placed in the folder share/proj National mapping agencies typically provide these grid-shift files. As an example, our S

Hi, It is my understanding that the parameters used in QGIS for that transformation are not sufficient  and will simply lead to a change in EPGS code number with no actual changes to the coordinates. If you are dealing with data in the 20k to 250k (like topo maps, SRTM), you can go ahead with

[Qgis-user] SpatiaLite - sqlite database delete

2016-03-31 Thread Lester Anderson
Hi all, Very quick one. How do I delete a Spatialite sqlite database? Cannot see an obvious way in DB manager. If I delete the .sqlite file in Windows explorer, it still shows up in the list. Did read that these databases could be deleted via the QGIS browser, but did not see any way there either
