LAB 2 Data Quality - Standards

In order to the begin the process for the accuracy statement first I had to create reference points based off the satellite images. Then I created IDs for each of the sets of points from the intersections of the lines and for the reference points that were created from the visuals. After that I created columns in the attribute tables of each set of points for their XY coordinates then I inserted the coordinates into the worksheets that calculated the data and from that I determined the accuracy.

ABQ CITY DATA
Using the National Standard for Spatial Data Accuracy, the data set tested 13 feet horizontal accuracy at 95% confidence level
STREETMAP DATA
Using the National Standard for Spatial Data Accuracy, the data set tested 180 feet horizontal accuracy at 95% confidence level

LAB 4 Surfaces: TINs and DEMs

During this lab I worked with DEMs and TINs in ArcGIS Pro. I learned about the difference between DEM and TIN where I learned that TINs are created from elevation points and they create face of triangles on the surface. While the DEMs represent a continous surface and the cell sizes are all the same unlike a TIN. Each though can make contour lines with some differeneces for example the TIN contour lines have an index lines and the lines are more jagged. The DEM contour line are much smoother though surprsingly their accuracy is similar.
