Assignment 2

Discussion

The purpose of this assignment was to familiarize ourseleves with some more of the functionality of ArcMap^TM .

We were to use the data given to us that consisted of 2 shapefiles – one of Pan Evaporation sites around New

Mexico and the other of the State of New Mexico, including county information.

Through manipulating the display symbology and by examining the attribute table of each respective shapefile,

we were to “tell a story” of pan evaporation in New Mexico. By symbolizing the pan evaporation sites by range,

I aimed to show the geographic distribution of pan evaporation rates across the state. With more information

(i.e. other data layers like average annual temperature) correlations could perhaps be shown.

This assignment went smoothly, except that I could not copy the legen of my graph into the display window. I

wanted to include the graph on the layout to show the actual amount of annual evaporation for each station.

Without the legend, the graph is more or less irrelevant. A separate output of the entire graph is shown below.

(A great feature of the graph, when displayed in ArcMap^TM, is that when you click on any of the graph elements

(i.e a line, bar, pie slice, etc.) a full table of its associated attributes is displayed).
