Hi Stefan, Thanks a lot for your recomendations, it helped a lot! I think the best way is to test each possibility in the field, before decide what to use I looked GeoODK documentation and it looks very suitable for what i need (justt need few modifications). As you said QField looks very pro

Hi Marco, Some of my colleagues made quite good experience with “full” QGIS on a Win8 Tablet (8’’) for a tree database. Since we needed a Desktop solution for the database anyway, we just copied the QGIS project (where we defined forms and so on) to the tablet (as you intended). Done. The Intr

Re: [Qgis-user] How to convert raster routes into vector format?

With QGIS 2.10, the following should work (probably also OK for earlier versions). Check the band values of your colour using the info button, and use the values in the expression below (assuming the name of your raster layer is yourraster) instead of 116, 20 and 31: ("yourraster@1" = 116 AND "

Hi Tonino You can force the data type of columns using a .csvt file that that you install alongside the .csv file. This file is a text file with one line defining the types of each field. You can read about this in the help for the delimited text provider (though it is quite brief). I've cop

Hi Håvard, I found the raster calculator and read the online manual for it, however am still a bit lost. I was also playing with the Style properties and color bands last night to try to accomplish this. I was unable to get a single binary image with the single color (red in this case). I th

Hi Firman and Nathan, thanks for your answer! Nathan, your project is fastastic. However I must work with offline maps, thus I need to use android. Does your company plan to build an android application to IntraMaps? Firman, how do you integrate ona and GeoODK? Cheers! 2015-07-29 9:26 GMT-03:00

Re: [Qgis-user] How to convert raster routes into vector format?

If you are going to use GRASS r.to.vect (for instance through QGIS Processing), you will need a binary skeleton image. You could get one by using the raster calculator to extract your single colour as a binary image, and then GRASS r.thin (available in QGIS Processing) to get the skeleton. Håvard

Re: [Qgis-user] how to avoid the automatic conversion of a session string in a csv file to a number

Ciao Tonino, if you are comfortable using python, you can circumvent the automatic trimming of leading and trailing zeros by adding your CSV layer from python. From the API documentation http://qgis.org/api/classQgsVectorLayer.html in the "*Delimited text file data provider*" Section, you'll see t

Dear all, Can anyone tell me how to prevent qgis automatically convert a csv file from text field to numeric format (double). I have a csv file where a field contains texts starting with zero (example: "04200509", with the quotes). When I add to my project file as "layer delimited text,"
