Re: Projection and Default Extent details
by
Camptocamp SA, Yannick Payot
Hello Magnus,
Welcome, this mailing list is indeed the right place.
1/ The default projection is EPSG:3857 (EPSG:900913 is the same but the name is deprecated)
2/ The extent is the Openlayers extent format. https://openlayers.org/en/v3.20.1/apidoc/ol.extent.html (which is not much more helpful)
As map is automatically centered on the features you created.
As map is automatically centered on the features you created.
The simplest way to get an idea of the extent you want might be to
- add a centered geometry where you want your extent
- open a js console launch Odoo with debug=assets add a breakpoint in there: https://github.com/OCA/geospatial/blob/77abc5e351e7b588ad5575b44cb6eb5a7230b8a3/base_geoengine/static/src/js/widgets/geoengine_widgets.js#L135
- reload the page
- get the result from this.source.getExtent()
3/ You would have to transform your decimal degree to the projection.
4/ vector layer (geometries aka features) can have a different projection than the raster layer (map background like osm)
The projection must be defined on the field in Python file.
Additionally, you might also want to configure the zoom level.

Hi all,
I searched the web for answers but could'n find any help. Hope this is the right place.
I'm trying to develop an app for our customer using the base_geoengine module.When opening a map view, the default view is Europe somewhere. I can see the default extent is set to ('-123164.85222423, 5574694.9538936, 1578017.6490538, 6186191.1800898'). This must form 2 corners of a rectangle I presume so I tried many things to get New Zealand to show up but didn't succeed.
Can someone explain:1 - what coordinate system is that?2 - what each element is (bottom x,bottom y, top x, top y)?Attention: This email may contain information intended for the sole use of the original recipient.

The content of this email does not necessarily reflect the views of Solnet Solutions Ltd.3 - How can I use normal decimal degrees?4 - If the map view uses a projection of EPSG:900913 must the vector layers also use EPSG:900913?
I have tried an extent of India using this but also failed:
