GPS Observations Comparing
Choosing Point 4 and Point 5 to compare its coordinates.
Point 4 shows a small difference in x and y but it’s high in the elevation.
Point 5 shows a very bad deference especially in the X value (expected because it is located nearby the building of College of Engineering).
Points Observations
Measuring coordinates (x, y, z) of all the features (tress, streetlights, etc)
Total number of observations is 356.
Processing Data
Using LISCAD 2018 S.E.E. to Process the points (linking the points with lines and curves and applying the counter model).
Using AutoCAD to make some enhancement (changing colours and fonts, etc) and to add some map features (a legend and a north arrow, etc).
