Display Name: Priority Habitats Overview (Highest Score by Area)
Description: Priority Habitat Overview
Summary map (vector) showing areas ranked as Very High or High Priority, and based on the highest score shown on "Scoring by Layer". See that map for individual scoring.
Methods:
1. Priority Scores were calculated for 20 base maps -- 9 that focus on Habitat and 11 that focus on Species. These were all based on shapefiles (vector-based maps).
2. Priority Scores for the 20 base maps were collated in the "Scoring by Layer" raster layer. A raster map can only store integers within a given area (pixel). The pixel size used was 5m x 5m.
3. The highest Priority Score within each 5m x 5m pixel are presented in “Scoring by Layer”. This map also shows individual scoring for each map (shown as individual bands of data), i.e., it shows results from rasterizing the original base maps.
4. The summary data from Scoring by Layer was then transformed back into a vector layer (Priority Habitats Overview) to allow better presentation and easier analysis of the data.
5. Note that some of the 20 contributing layers include a third Priority Score (Moderately High) which is not include in the Scoring by Layer or Priority Habitat Overview. This decision was made to highlight only the highest priority areas.
