GIS Model

The Planning model for GIS has been completed. We can now select parcels and automatically generage aggregate acreages fo upland and wetland areas of the parcel selection group as a whole. This model will work with any of the county parcel datasets in the SWFWMD area, as it is their data set that we use primarily for wetland lines.

Working on this has proved what a valuable tool ESRI's ModelBuilder tool can be especially when coupled with the built-in Python gepreocessing API.

Our next step will be to calculate unit densities based on the upland vs. wetland ratios and the adopted future land use coverages. Because the various Florida counties use different density calc. rules, we will either have to make a new model for each county, or create a rule-library and have the end-user select the county for which they are seeking a density calc. Now that I come to think of it, the model should determine the county based on the parcel location and select the correct county and alert you if the parcel selection group crosses county lines. Incorporated area need to be entered into the mix too as they sometimes place more restrictive density rules than their respective counties. Hhmmm....

Okay, Gecko, here's your first legitimate comment. Sounds like you're into the problems of building the new digital SWFWMD. Best of luck. Hang in there. The rest of the world is just behind you.

By the way, you might be interested in typing in "SWFWMD" in Technorati's blog search engine. You can find it at http://technorati.com. ... or you can just visit http://swiftmud.blogspot.com.

Again, best of luck and keep up your postings.
