Nature in Norway / Natur i Norge (NiN) QGIS plugin

This plugin is designed to create a QGIS project for mapping nature using the NiN system in the field.

Description

The user is presented with several options for customizing the QGIS project.

  • option to sub-set the NiN system by choosing the relevant Type system and Major Type Group/s for the current mapping project.
  • mapping scale
  • filepath to save the project to
  • select background maps

This creates a QGIS project file and a geopackage file with the selected Type system and the underlying selected Major Type Groups. Mapping units are adjusted based on the selected mapping scale.

Getting Started

  1. open QGIS
  2. download and install 'nin-qgis-plugin' in QGIS > Plugins > Manage and Install Plugins > searching for "Natur i Norge"
  3. pick the relevant NiN Type system, mapping scale, file location and background maps for the QGIS project
  4. click "Load Geopackage and adapt project"

this creates all the necessary files for mapping in QGIS and adapts the QGIS environment with the following:

  • all layers from the geopackage are loaded containing necessary tables with the NiN type-system
  • hierarchical relations are set (major types dependencies on major type groups)
  • CRS is set to ETRS89 UTM33 ("EPSG:25833")
  • topological editing is turned on
  • avoid overlap on the nin_polygons layer is enabled
  • snapping is set to 5px on vertex and segment
  • nin_polygons layer is set up with unique random color symbology and labeled by the minor type- depending on the selected Major type groups

in case further adaptation of the project is neccessary:

  • users can add additional raster/vector layers using standart procedures in QGIS

Exporting the project to Qfield

  1. After project and geopackage were generated, users can transfer the project to Qfield and hereby to a mobile device / tablet or a field computer

The mapping procedure

  1. select layer 'nin_polygons'
  2. toggle layer editing
  3. add poygon feature
  4. fill out the NiN information and attributes in the Attribute Form
  5. relevant variables for the chosen NiN type are displayed for mappers convenience
  6. mapper can select up to 3 NiN types within one polygon by selecting "Andel av naturtype" to less than 100 and selecting "sammensatt or mosaic"
  7. take a picture of the NiN type (available on devices with integrated camera)
  8. approve the polygon registration with "OK"

Mapping guidelines can be found on Norwegian Biodiversity Information Centres (Artsdatabankens) website
