Assignment 2

New Mexico annual evaporation

To create the New Mexico Pan Evaporation project I first uploaded the files provided for the state of New Mexico and the NM EVAp data. I changed the symbols to better be visually pleasing. To focus in and simplify the data I divided the pan evaporation data into 3 classes instead of 5. I also removed the decimal places from the end. To create a location map I added a second layer and included the New Mexico shape file as well as a United states shape file.

Using the directions given I created the graph. To simplify the graph I used only the stations near the river. To this I selected the stations I wanted and in the second menu under the graph options I selected use selected data. My biggest problems in doing this assignment were figuring out how to add the location map, scale bar and index. These problems were simply solved. After a bit of trial and error and a few minutes in the help menu I discovered to add the index and scale bar I had to be in layout view. Once I had the scale bar on my layout, I played around with the scale. I tried a few things but kept getting values hundreds of times less than what I believed to be actual. By making the scale on the layer be in decimal degrees and the scale bar in miles, I eventually produced a scale I believed to be accurate. To create the location map I again used trial and error and eventually found that adding a second layer was an easy way to accomplish this task.
