#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
This is my default career advice for people starting out in geo/GIS, especially remote sensing, adapted from a response to a letter in 2013.
I'm currently about to start a Geography degree at the University of [Redacted] at [Redacted] with a focus in GIS, and I've been finding that I have an interest in working with imagery. Obviously I should take Remote Sensing and other similar classes, but I'm the type of person who likes to self learn as well. So my question is this: What recommendations would you give to a student who is interested in working with imagery? Are there any self study paths that you could recommend?
I learned on my own and on the job, and there are a lot of important topics in GIS that I don’t know anything about, so I can’t give comprehensive advice. I haven’t arrived anywhere; I’m just ten minutes ahead in the convoy we’re both in. Take these recommendations critically.
Find interesting people. You’ll learn a lot more from a great professor (or mentor, or friend, or conference) o
