Local Climate Zone (LCZ) mapping
Motivation: Land cover types and spatial structure of built-up area well correlate with air
temperature.
Task: Use Google Earth map of Your city, PPT presentation explaining concept of LCZ and study
material (link below) and find a typical representative of individual LCZs in Your city.
Draw 1-3 polygons that well represent individual LCZs in Your city. See Figure below as an example. In
Google Earth You can add the legend (LCZ types with selected color) as follows:
Right click on
My places -> Add -> Folder
Create name of the of the folder – e.g. LCZ3
Then right click on LCZ3 folder
LCZ3 -> Add -> Polygon
Create name of the polygon (e.g. Site_3_1) and select color of the polygon, do not close
window and place mouse over the map.
Find suitable place - left click defines polygon outer points, right click close the polygon
Repeat for 2–3 polygons for each LCZ
Now create folder for another LCZ – e.g. LCZ4 and repeat as above
Alternatively, You can create only the polygons (without folders). In this case You mast add proper
names to individual polygons (see example – figure below)
Finally save Your map as follows:
File –> Save -> Save folder My places
This creates file My places.KMZ on Your computer.
When finished, please send me KMZ file and text shortly discussing: 1) which LCZs can be easily found
in Your city according Your opinion; 2) which LCZs do not exist in Your area.

Notes:
 It is not necessary to cover the whole area; find just typical spots as a “training sites”
 Not all LCZ categories must occur in Brno area
