Re: [QGIS-Developer] Compatibility between 2.99 project files and 2.18

Older versions can read enough of the project files to be functional, however. At some point someone will need to use an older version to resolve a bug in a newer version. On 24/11/17 17:14, Nyall Dawson wrote: On 24 November 2017 at 14:10, Patrick Dunford wrote:

[QGIS-Developer] Compatibility between 2.99 project files and 2.18

As of the moment I'm finding that 2.18 has difficulty correctly detecting the CRS from a project file saved from the latest master. Generally EPSG:3857 is detected as EPSG:4326 Given the master is still a development version is this considered a bug in 2.18 or is there still a process of

Re: [QGIS-Developer] GRASS r.walk

Is it normal for an r.walk over an area of 10,500 acres to use up 12GB of HD space and want more? That's using up every bit of space I have left, so it's crashing out. I tried setting the maximum cost to 10 and I think 1 also, but the algorithm keeps running for a long time making these really

Re: [QGIS-Developer] QGIS Server request extra parameters as variables for expressions

@Patrick : Yes, I know that it is possible to use FILTER in request, but I'm not sure all layers will have the same field name for "floor". So I would prefer to define a filter in each layer definition in the project file using a common variable name. And I would like to have the same

You could do that using the filter parameter with something like that: FILTER=layer_name:"floor" = 3 On Thu, Nov 23, 2017 at 2:38 PM, Matthias Kuhn wrote: > Like WMS dimension? > > http://mapserver.org/ogc/wms_dimension.html > > Matthias > > > On 11/23/17 2:11 PM, Arnaud

Re: [QGIS-Developer] QGIS Server request extra parameters as variables for expressions

Hello, I would like GetMap and GetFeature request extra parameters to be accessible as variables in server. So we could define, in QGIS project, a variable "floor", used to filter layers. On desktop side, we could have a desktop plugin named FloorSlider to change the "floor" value. And

Re: [QGIS-Developer] Refactor Fields: save and load mapping configuration

Hi, this is awesome and something I have been trying to push towards at a lot of meetings over the last year. It reminds me a lot of this proposal by Arnaud Morvan, with the technical details that are required to get all your wishes working:

Re: [QGIS-Developer] Refactor Fields: save and load mapping configuration

Hi Régis, I agree - it would be good to brainstorm what's missing to have an FME-like ETL environment. I see that you are coming to the Madeira dev meeting. Would be a good opportunity for such discussions and then open the QEP in parallel (or open it before and work on it). BTW: refactor

Re: [QGIS-Developer] Refactor Fields: save and load mapping configuration

You could potentially use a model to save refactor fields settings. That said, there's currently a problem (see issue https://issues.qgis.org/issues/17421) preventing this algorithm from being used in a model. M On Thu, Nov 23, 2017 at 3:01 PM, Andreas Neumann wrote: > Hi,

Hi Andreas, I don't have any answer to that particular question, but in many project we are working for, it becomes clear that we need to push processing to become an ETL, and the field mapping component is clearly a key feature. What do you think about opening a QEP and store in there all what's

[QGIS-Developer] Refactor Fields: save and load mapping configuration

Hi, The refactor fields algorithm is potentially very powerful. However, I do miss a way to save and load the configuration (or maybe I just haven't found it). I have layers with many fields and I am adding additional fields with expressions. Every time I run it, I have to do the
