i-Trees Canopy Ward Data

Ward boundaries for all London boroughs suitable for use in i-Trees Canopy tool.

Based on Ordnance Survey Boundary-Line data available from the OpenData website. Data has been converted to latitude/longitude values (WGS84 geographic coordinate system) and saved in shapefile format, suitable for use on the i-Trees website.

The i-Trees tool offers a quick and easy way to produce a statistically valid estimate of land cover types e.g. tree cover, using aerial images available in Google Maps. All that is required is an internet connection and a shapefile which defines your study area.

We recommend using the boundary of your ward as a study area and this can be obtained by downloading the zip file for your Borough below. Each zip file contains individual shapefiles for every ward in that area. Each shapefile requires four different files in order to work correctly so please ensure these are all extracted from the zip file before trying to upload on the i-Trees website. For example the shapefile for Brockley ward in Lewisham consists of the following files:

-Lewisham_Brockley.dbf



-Lewisham_Brockley.prj



-Lewisham_Brockley.shp



-Lewisham_Brockley.shx
