3-D Analysis

Using ESRI's 3-D analyst, I collected LIDAR points (one foot elevation points obtained by flying a plane equipped with a laser). This data was tranformed into countours, then a digital elevation model was created with the pixels colored to
represent different elevations. This model was then drapped by a 2009 aerial photography. As you can see, the program stretches the aerial photo to fit the shape of the digital elevation model. Making the aerial partially transparent, allows the elevation colors of the model come through.
This analysis shows that the area to the east of the St. Mary's River, assumed to be higher than the river, is actually lower than the bottom of the St. Mary's River.
The consequences of which are obvious.
