#OSM Tracing Guide for Khayelitsha, South Africa
Khayelitsha is a slum in Cape Town, South Africa, where the American Red Cross and its partners will be piloting a solar-powered fire sensor system. Fires regularly occur in urban slums like Khayelitsha, often resulting from indoor stove use, trash burning, faulty wires and residents trying to keep warm. Evacuation can be very difficult, making fires a very dangerous event.
The results of this mapping will guide fire sensor program decisions/planning and will be used by firefighters during their response operations.
This tracing guide focuses on the most important features in the area: buildings and roads.
##Getting started
There are a few types of aerial imagery available and iD editor should default to using Bing. If your imagery looks blurry or hard to see, use the menu on the right side of the screen and double-check that imagery is set to Bing aerial imagery. You can also brighten the imagery here, if it's difficult to see.
The area is very dense, so zoom in as much as possible to do the mapping.
##Buildings and walls
###Understanding what's what.
We're interested in the following types of area:
- Buildings. These will look like "normal" structures, with roofs, walls, etc. These vary a lot - they may be constructed from metal, wood, or primitive materials.
- Buildings under construction. These will look like walls, but about the size of a building and with partitions for rooms. These could be dark (indicating that a foundation has been dug), lighter (indicating a filled-in foundation, maybe with short walls), or white with shadows (the walls are getting taller)
