Final Map
This map shows the analysis of the Pierce County Transit system in a flood event. My goal was to create a map that was easy to understand and simple. I didn’t want the map user to get bogged down with unneeded information. There were a few versions of the map that I originally created, but for one reason or another decided to change. This is the final map that I came up with. I feel that it conveys what I want the map user to learn without a lot of unnecessary information. The maps that follow are the steps that I took to get to this map.
All Raw Data
Once all my raw data was added to the map this was the outcome. I wanted to just concentrate on Pierce County. The Pierce County Transit doses extend in to King and Thurston Counties. I eventually clipped the Pierce County Transit to just the base map.
Getting the right data
By this step in the proses I was getting my data sorted out. I had clipped the Transit layer, dissolved all the small segments that make up a transit route into one route and had performed an intersecting analysis to see exactly what segments of each transit route are affected during a flood. The only thing left to do was the figure out what percentage of the route was affected during a flood.
Analysis is Done
All of the analysis is done by this point. The Pierce County Transit layer has been symbolized by what percent of the route will be affected by a flood. Now the only thing left to do is to make the map presentable.
Close, but not quite right
This was the second to the final map. There were a few minor changes from this map to the final map. The biggest change was that I decided to leave out the flood layer. I played around with it, using different transparency levels. The map shown has the flood layer at a 60% transparency. Ultimately though I decided the map could stand without the layer. I wanted to show what percentage of the Pierce County Transit could be affected by a flood event, not how much of Pierce County would be flooded.
