Week 7: Data Editing

This map was cool to do. I am enjoying learning how to insert data because I will likely be doing a lot of it within the next year. I really didn't have any problems but it was bugging me that the shapes were not always square but I guess that is my fault. Human error :-(

Week 6: Geotransformations

Geotransformed Map

I am glad to have learned this as I can see how it will be a very handy skill!! One thing I did have a problem with was the first time I did it, the scale was for some reason not linked to the map scale. In fact I couldn't type in the scale like normal so I had to start over. I think it may have either been due to me adding all three layers at the same time but am not sure. Anyway, here are my total RMS error values:

*North Map - 1st order = 8.00246
South Map - 1st order = 31.99860
South Map - 2nd order = 11.95450
*South Map - 3rd order = 8.86964

* indicates order displayed in final map product

Week 5: Bradford County, FL

Land Cover Map

This map focuses primarily on land cover. It also shows main roads and rivers. One issue I had with making this was that the land cover raster file had too many different bins/classes to fit in the ledgend. For this reason I went through and deleted some that were aquatic and wetland oriented since those are seen by vector files present in the map. Still, it may have produced some areas that are not coverd by either. With the land cover data, I am worried that it may appear too busy but I think for all of the data that is on there it is displayed rather clear and simplistic. Also, the shape of the county caused my map to have alot of empty space which isn't exactly great.

Quadrats Map

In this map I used the quads to display the DOQQ, DEM, and DRG files. After having issues finding the DEM (for quads) and the DRG files, I finally found some that worked. One thing I would like to learn how to do is how to clip a raster file using a vector file. Not sure if this is possible, but it would be nice to just have the maps in the county rather than across its border. I also threw in the rivers and roads along with some other layers to add to the map and help in determining position.

Week 4

Coordinate Projections

I am not sure if you wanted us to post this so I figured I would just in case. I really did not have much trouble with this one and it was very interesting. I learned I had been misusing the word datum with previous GPS related activities. Other than that, it is a good and useful thing to know that will take some more familiarization but will pay off by saving time.
