Special Topics in GIS (GIS5935): Lab 15

In this week's lab, we learned about the dasymetric mapping. Dasymetric mapping is improving on the results of standard population density in areal weighting by using additional data. We applied this mapping technique to high school zone in Seminole County, FL. We were trying to predicted the number of students between the ages 5 through 14 will be placed in which school zone depending on the location.The imperviousness method seemed to increase the percentage of allocated incorrectly students. This may have to do with the increase area of the school zone not missing the area without the water features.In the areal weighting, the percentage was 44.88%: however, the imperviousness method's percentage was 45.62%.
