A QGIS plugin
Plugin "NIB-ortofoto-prosjekt"
NB! Th eplugin will ONLY work for those with access to "Norge i bilder ortofoto-prosjekt WMS".
NB! The project must be in EPSG 25832, 25833 or 25835.
Get one, several or all orthophoto-projects in map canvas from "Norge i bilder prosjekt (WMS)" for one, several or all years available.
The bounding box may be
- the visible map canvas (default)
- a bouding box given by the user in integer km (width x height)
- a layer in Layers panel
- an uploaded file
- the visible map canvas
- an uploaded vector og raster file
The orthopohoto projectnames may be written to sorted/unsorted text file(s).
The maximum size of the bounding box is set to 500 km x 500 km.
Resources used:
- Plugin Builder to achieve correct configuration and neccessary files:

A QGIS plugin
Plugin "NIB-ortofoto-prosjekt"
Hent alle of-prosjekt i et utsnitt fra Norge i bilder (WMS)
Utsnittet kan være bounding boksen til
- et kartlag i Layers panel
- en fil man laster opp
- aktuelt map canvas
Ressures brukt:
- Plugin Builder for å få riktig oppsett og nødvendige filer
- https://www.qgistutorials.com/en/docs/3/building_a_python_plugin.html
NB! husk å lage og å kopiere over compile.bat (trengs for å kompilere resources.py slik at f.eks. eget icon skal bli synlig)
