Re: [Qgis-user] Copy field definitions from one vector layer to another?

ok, you are right. You can import your shapfiles into spatialite using dbmanager, then copy the definitions of the first layer, add column to the other layer and then export to shapefile. Luca 2015-10-22 5:17 GMT+02:00 Richard Males : > The join works without a common field of any kind, which

Update: Fixed it. Manually placed the following file in path ( /usr/share/qgis/resources/ ): https://github.com/qgis/QGIS/blob/master/resources/srs.db But it is not a good solution. Need to be fixed in relevant packages itself. Thank you. 2015-10-22 10:49 GMT+05:30 Jaisen Nedumpala : > Hai,

[Qgis-user] SUMMIT elevation map from a DEM ( SRTM)

I need to create a SUMMIT elevation map from a DEM ( SRTM). At every square km I need to extract : Lat, Long and MAXIMUM elevation ( within that square km) and so on for all the grid. Someone suggested topology-algebra but that is too much for me !. I will appreciate a "receipt" or any other practi

[Qgis-user] Debian jessie - QGIS 2.10.1 'Pisa' - can't find srs.db - reg.

Hai, Debian jessie - QGIS 2.10.1 'Pisa' - Can't find /usr/share/qgis/resources/qgis.db. It is a matter of urgent. Need help. After an upgrade, when tried to change CRS of a shapefile, it is found that no coordinate reference systems are listed there in the Coordinate Reference System selector dial

Re: [Qgis-user] Copy field definitions from one vector layer to another?

You can change the prefix of the column names in 2.10 there is a tick box in the join dialog. not sure if you can set it to blank, but might work? From: Qgis-user [mailto:qgis-user-boun...@lists.osgeo.org] On Behalf Of Richard Males Sent: Thursday, 22 October 2015 11:17 AM To: Luca Lanteri Cc:

Re: [Qgis-user] Copy field definitions from one vector layer to another?

The join works without a common field of any kind, which is what I wanted, but unfortunately the field names get prefixed with the join layer. When I export as shape file from the joined layer, I get field names like 'exported', 'exported_1', etc. So I don't think the join will work, since what

Re: [Qgis-user] qGIS and Avenza pdfMap

Hi Laurence, I have in the past, imported my QGIS data into Global Mapper and used that to create GeoPDFs for use with Avenza's wonderful PDFMaps program. I'll be very happy if I can skip that step and do it all in QGIS, but I don't understand your step 2 ("Upload the tiff file in QGIS") - upload

Hi, Thanks for your answer, Tim. The framadrop link is working on my side. You may try again. So to directly answer to your question without the framadrop issue. In fact, I do not declare any layer here in the code but I only reference a different "qgs" file. One is with only a shapefile (Natura

Re: [Qgis-user] Fwd: QGIS hardware recommendations?

Hi, The general answer is as much and as fast as you can get - cpu, memory & disk. Depends as much on your expectations, patience & workload as anything :-) If you are working with lots of data, memory & disk, anything analytical, cpu - and note that reprojecting on the fly counts as analytical

Hello Wangyal, There are OR and AND operator in the raster calculator. Try putting a curved brackets around the expression. In the following expression the cell will receive the value 100 if incomras >= 2 or disclasras >= 3 or sanitatras != 0 (("incomras@1" >= 2) OR ("disclasras@1" >= 3) OR ("sa

Re: [Qgis-user] Adding postgis views to qgis

You can add views from the add postgis layer but your view must have a few tweaks. First, add an Id, even if a fake id with rownumber () over (). Then, you need to explicitly cast your geometry and CRS. Therefore use this instead ST_DumpPoints(geom).geom::geometry('point',your_EPSG_code) A 17h
