Presentation form

Digital map

Purpose

This dataset provides a non-overlapping polygon layer of the NVC survey coverage. This is derived from the NVCCONV_EUNIS_COVERAGE_MV dataset in geo.Store. It covers the NVC habitat surveys currently in the Habitat Map of Scotland as of October 2023.

Statement

This dataset provides a non-overlapping polygon layer of the NVC survey coverage. This is derived from the NVCCONV_EUNIS_COVERAGE_MV dataset in geo.Store. It covers the NVC habitat surveys currently in the Habitat Map of Scotland as of October 2023. This dataset does not include the Saltmarsh survey 2013, Sand Dune Vegetation survey 2012 or Coastal Vegetated Shingle survey.

Processing survey coverage overlaps:

1. Data was extracted from NVCCONV_EUNIS_COVERAGE_MV dataset in geo.Store then a process was done to identify which surveys overlapped with others.

2. Groups of overlapping surveys were identified, work was done one group at a time.

3. Prioritising overlapping surveys was assessed with the help of an habitat expert. Factors that influenced decision were: age of the survey, quality of the survey, quality of surveyors, expert knowledge, existing survey metadata.

4. Parts of lower priority surveys were removed where they were overlapped by a higher priority survey.

5. Final coverages without overlaps were used to clip their corresponding habitat polygons.

Notes and caveats:

• Processing survey coverages created slivers.

• Some of the original NVC polygons had an empty description field. This is the reason why sometimes we have the coverage of a survey not covered completely with habitat polygons.
