Subject of the issue

The extent srs doesn't works very fine with other srid (like 4674).

Tested other situations, just is fine with config QGS project with srid 4326. I dont know with have some relation with this commit on g3wadmin: Add generic srs extent, instead of CRS bbox.

When use other srid (that is not 4326), have problem with zoom (zoom in, zoom out and zoom to box) and the check box on "User QGIS project map start extent as webgis init extent" have error.

I have two version of G3WSuite (diferents servers), both with docker compose:

• Ubuntu Server 18.04 with G3W-SUITE Version 3.5.dev-20230120114529 (all right)

• Ubuntu Server 22.04 with G3W-SUITE Version v3.6.6: administration GIS application (error)

Steps to reproduce

1. Config QGIS project to SRID 4674
2. Create a Cartographic Group with GEODATA (EPSG 4674)
3. Import QGS project to Cartographic Group. (if Advertised Extend on QGS project is checked, have a error on "User QGIS project map start extent as webgis init extent". Unchecked this box to save and open map view.
4. Open Map View, had a error with zoom (zoom in, zoom out, zoom to box).

Environment

• g3w-admin: 3.6.6
• g3w-client: version
• browser: Google Chrome
• operating system client: Tested Ubuntu Studio and Windows 11.

Hi @gustavoeugenio

Open Map View, had a error with zoom (zoom in, zoom out, zoom to box).

Please also attach a gif (or video) showing the problem, otherwise, it may be difficult to understand which is the "error" you are referring to..

g3w-client: version

through the browser console, you can find out the currently installed g3w-client version 👉 g3wsdk.info()

Import QGS project to Cartographic Group. (if Advertised Extend on QGS project is checked, have a error on "User QGIS project map start extent as webgis init extent". Unchecked this box to save and open map view.

In this regard, please consider:

• opening a separate bug report (if not closely related to this bug)
• attaching a minimal reproducible example qgis project and/or other self-explanatory images

I'm moving this to g3w-admin due to the following statement

I dont know with have some relation with this commit on g3wadmin: Add generic srs extent, instead of CRS bbox.

@gustavoeugenio please add the requested information in here: #584 (comment)

In the absence of a response, we will close this soon as we can't reproduce statements like the following:

Open Map View, had a error

Advertised Extend on QGS project is checked, have a error

Hi @gustavoeugenio, I made a test on v3.6.9 with EPSG:4674 , but I don't have any issues with it.

Advertised Extend: false (unchecked):

Advertised Extend: true (checked):

@wlorenzetti, thank you for your response, and I apologize for the delay in posting here.
We are currently using G3W-Suite Docker version v3.6.6, and we are still experiencing issues with SRID 4674 when the scale is below 1:83630, causing the zoom to be locked.
We have attached the data source, QGS project, and a GIF demonstrating the issue.
Currently, we are working on our projects with SRID 4326, which has no issues.
We also tested the UTM projection (SRID 31982) and did not encounter any problems. (atthahed too).

@volterra79 when you have time can you test EPSG 4674 with data linked above?

@gustavoeugenio it is a issue linked to the definition of the ESPG 4674, OL doesn't work fine with proj4 definition coming from QGIS api, so is necessary override the ESPG definition, inside your g3w-suite settings add the following lines:

G3W_PROJ4_EPSG = {
    4674: {
        "proj4": "+proj=longlat +ellps=GRS80 +no_defs +type=crs",
        "extent": [-122.19,-59.87,-25.28,32.72]
    }
}
