Faithway Drive, Seffner, Florida Sinkhole Area Map - Click on Map for a Larger Map that you can Download

I have created this map of the Karst sinkholes in Florida using ESRI ArcGIS 9.3. The sinkhole GIS data (depicted as yellow double-circles) is somewhat dated, and was downloaded from the Florida Department of Environmental Protection webpage about the Florida Geological Survey, Subsidence Incident Reports. The webpage a that link will prompt your for a valid email address, before you can download any GIS data about Karst Sinkholes, which they refer to as subsidence incidents.

The subject sinkhole of this webpage, the Bush property, in Seffner, was geographically created from a variety of sources, the local news for the description of the incident and Google Earth, to obtain the latitude and longitude of the sinkhole location. This data was then entered into a new ESRI shapefile that I specifically created to match the State's sinkhole shapefile, and brought into this map.

How Sinkholes Form is a very informative webpage about sinkholes in Florida, it is hosted by the St. Johns River Water Management District.

Some local and state-wide GIS data can be found on the St. Johns River Water Management District's GIS Development Program.

I enjoy working with GIS data and try to find new things to keep my skills honed with.

Within these pages, I am performing some GIS tasks about the Karst Sinkholes in Florida. After seeing the news about the 100 foot-side sinkhole that had opened up behind a house in Windermere, Florida, I decided to see what was available for historic sinkhole data and started developing this webpage, complete with a time-lapse video of the historic locations of the sinkholes.
