Lab 15: Dasymetric Mapping

In this lab we explored dasymetric mapping. Dasymetric mapping is a process used to break down one set of data using ancillary data in order to use it in another set of data. A common example for a use of dasymetric mapping is taking census block data and properly applying and dividing it amongst other data that has mismatched boundaries. We did that in this lab with census blocks and high school districts in Seminole county, Florida. We were required to divide the prospective students up into the proper high school districts using areal weighting and dasymetric mapping. Dasymetric mapping has a track record of being more accurate. In this lab unfortunately I couldnt seem to get that to happen. My dasymetric map was twice as inaccurate as the a real weighted one.
