Welcome to the GHIA Extract Tool

Use the map to get a report of the type and amount of green and blue cover for an area of Greater Manchester. You can click a single point, draw your own area or select an administrative area (lower-level Census zone or Ward).

A report will be generated with details about the green and blue cover for:

  • a square of 1km size (point option)
  • inside your drawn area (area option)
  • inside a selected administrative zone (zone option).

To find out more about the maps, read our paper . By green and blue spaces we mean things like parks, gardens, canals and rivers, woodlands, street trees and any other areas of water or vegetation. For more information, see about the project and our other tools.
