Florida Geological Survey - Data and Maps
Sinkholes Database
|
Below you will find two different
types of files. One is an Excel Spreadsheet and the other is
an ESRI ArcGIS compatible shapefile. Both types of files have been provided
as self extracting .exe and zipped files. Each file provides information on possible sinkholes as reported to the Florida Geological Survey.
After clicking on any of the sinkhole databases links you will be taken to a page where you must
submit your e-mail address, your e-mail address is used only
to keep track of who is using the sinkhole database and will
not be used in any other way. After submitting your e-mail
address and before you can download the database you will be
asked to read and agree to a disclaimer.
A Word Document titled
"The FGS the FSRI, and Karst Data in Florida"
has been provided here for anyone interest in the history of
the Database and other Sinkhole publications.

Sinkhole Database in a Microsoft Excel Spreadsheet
In some cases
an executable (EXE) file cannot be downloaded. In this case, try to open the file that is indicated with the yellow star.
The excel
file has been made into a
self extracting file
and will self extract on download if you
select the OPEN option when the download begins. If
it does not extract on download
- Find the file on your computer
(the name will be sinkhole_database.exe)
- Double click on the file. You will be asked
where you would like to extract the files to.
The default folder is C:\FGS_SinkholeDatabase
- Once the
file has been extracted open the excel file named
README.TXT for
information contained in the compressed archive.
- Use this
word document
to help with identifying the fields in the
sinkhole database files.
The excel file is also available as a
zipped file (sinkhole_database.zip)
.
You will need to have software on your machine that will unzip the file. If you do not
have the software you can download a free evaluation copy of winzip at http://www.winzip.com/downwzeval.htm
 If you cannot download the self extracting
.exe file we have provided the excel file without compression. It is a 3.4
MB file and can take over 15 minutes to open when
using a dial up connection and a 28.8k modem.
Sinkhole Database in a
Arcview shapefile
This file is to be used with
any geographic information system software that can use
ESRI ArcGIS shapefiles. A FREE reader for shapefiles is
available at
http://www.esri.com/software/arcexplorer/index.html This file would be most beneficial to
anyone familiar with ESRI Arcview Software since only
the shape file and database for the sinkhole locations
have been provided. Follow instructions given above
for downloading the self extracting file with the
filename being sinkholeshapefiles.exe or
sinkholeshapefiles.zip.
The Florida Geological Survey shapefile formats are projected using a DEP modified ALBERS projection.
The ArcView and ArcMap projection data is available at: http://www.dep.state.fl.us/gis/projdata.htm.
