Maps

UC Roads and parking
This map shows the roads and parking available on campus along with campus buildings. Fault lines are also depicted so that drivers know which areas to avoid in the case of an earthquake. In addition, by mapping the "parcel_b" layer, we can see (in white) the roads outside of campus. The parking areas are drawn with a transparency level of 30%, allowing us to see underground lots without covering over the buildings that they are located under. I'm not sure why but intially I had a lot of trouble with this. However, once I figured out how to set the transparency correctly, everything was OK.

UC landslides map
This map shows the landslides that have taken place on the campus, along with buildings, roads, streams, and fault lines. Contour lines are also present to give an idea of elevation. We can see from this that landslides often take place in stream valleys. We can also see that a number of buildings on the far eastern side of campus appear to be very vulnerable to another landslide in the future.

UC vegatation map
This map, as can be seen from the legend, shows the different vegetation types prevalent on campus along with campus buildings, roads, and streams. Unlike the other two maps, this map was exported from layout view so that a legend could be added so that we could tell which colors represent which vegetation types. One strangeness, in my opinion, of the layout view is that the "zoom" button actually zooms the map on the page, instead of the page itself. It is also more complicated than it should be to get your current map view to simply be fit to the entire page.

UC soils map
This map shows the different soil types on campus, along with contour lines to show elevation. I decided not to display buildings so that the map does not become too busy.

Components of ArcGIS

ArcMap is used to put together spatial data and render it on a map. It also allows you export these maps and lay them out on a page for printing. ArcCatalog allows you to browse your data and edit the metadata associated with it. It also allows you to see quick previews of the data so that you can get a quick idea of what the data represents. ArcToolbox provides a number of tools for manipulating and analyzing your data.
