GENERAL DESCRIPTION:
This dataset contains Subsidence Incident Reports for the State of Florida. What is a Subsidence Incident? Sinkholes are closed depressions in areas underlain by soluble rock such as limestone, dolostone, gypsum, or salt. Sinkholes form when surface sediments subside into underground voids created by the dissolving action of groundwater in the underlying bedrock. Other subterranean events can cause holes, depressions or subsidence of the land surface that may mimic sinkhole activity. These include subsurface expansive clay or organic layers which compress as water is removed, collapsed or broken sewer and drain pipes or broken septic tanks, improperly compacted soil after excavation work, and even buried trash, logs and other debris. Commonly, a reported depression is not verified by a licensed professional geologist to be a true sinkhole, and the cause of subsidence is not known. Such an event is called a subsidence incident. The Florida Geological Survey maintains and provides a downloadable database of reported subsidence incidents statewide. While this data may include some true sinkholes, the majority of the incidents have not been field-checked and the cause of subsidence is not verified.

Generalized FGS Disclaimer
Geographic Information Systems (GIS) data and maps produced by the Florida 
Geological Survey (FGS), an office of the Florida Department of Environmental 
Protection (FDEP), are provided solely as a general reference for state geologic 
features, are not warranted for any other use or purpose, and are not intended to 
replace site-specific or use-specific investigations Use of FGS data and maps by 
an end-user for any purpose other than general reference shall free the FDEP and 
the FGS from any and all liability for outcomes resulting from unintended or 
inappropriate applications of FGS spatial data. Examples of such applications 
include but are not limited to the mapping of point data with respect to cadastral 
boundaries, the use of geologic data for engineering purposes, and the 
interpolation of results of broad-scale GIS modeled surfaces to local areas that 
may or may not be deemed geologically analogous.

As with all spatial data, the attributes and exact coordinates of features depicted 
in FGS maps, coverages and datasets are subject to inherent errors due to 
limitations in the resources and technology available to record data. Please keep 
in mind that older maps, projects, and data were developed using the best tools 
and knowledge available at the time, and that spatial data standards and the tools 
used to develop these data have improved significantly over the last several 
years. Existing maps and projects are sometimes updated and enhanced with new 
data of higher precision, and thus are subject to change. The FGS makes every 
effort to provide the most up-to-date and accurate geographic information 
possible, but cannot be held liable for the use of outdated data regardless of 
whether more current data have been obtained, analyzed, or made available by 
the FGS or FDEP.

Any modifications of FGS spatial data or maps by end-users must be 
acknowledged and noted appropriately in all subsequent products and analysis, 
and any FDEP/FGS logos or author information must be removed from altered 
FGS products prior to distribution to any other individual or entity. All FGS spatial 
data and maps are distributed on an "as is" basis and end-users shall assume all 
risks concerning data quality, performance, and analytic results. The same shall 
also be true concerning the use of unpublished drafts of FGS products, which may 
not be distributed to other individuals or entities without prior FGS approval.

Comments and inquiries regarding FDEP/FGS spatial data, maps, projects, and 
other analysis are encouraged and the FGS asks to be notified of any 
documented errors or inaccuracies. As a professional courtesy, the FDEP/FGS 
asks that due credit be given when our data sets are utilized by other individuals 
or entities. Further, since some or all of the data yielded from each FGS project 
were developed using public funds, no proprietary rights may be attached to FGS 
products wholly or in part, nor may FGS products be sold to the U.S. Government 
or the Florida State Government as part of any procurement of products or 
services. By using FGS spatial data or maps for any purpose other than general 
reference, the end-user acknowledges all the aforementioned stipulations and 
absolves the FDEP/FGS completely of any responsibility for unintended or 
inappropriate usage. For questions, comments, or observations regarding FGS 
spatial datasets or maps, including questions concerning appropriate uses for 
specific datasets, please contact the FGS GIS analyst listed below.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability

to any implied warranties of merchantability, fitness for a particular
purpose, or non-infringement. The University of Florida GeoPlan Center
shall not be liable for any damages suffered as a result of using,

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding

DATA LINEAGE SUMMARY:
SIRs_081011_WGS84.shp Dataset Updated
Process Date: 20110811 11023900

The GeoPlan Center downloaded the original dataset from the following Florida Department of Environmental Protection's (FDEP) - Florida Geological Survey (FGS) website on October 14th, 2011. http://www.dep.state.fl.us/geology/gisdatamaps/SIRs_database.htm http://www.dep.state.fl.us/geology/geologictopics/sinkhole/email_sink_arc_zip.htm SIRs_shapefile_081111.zip The dataset was originally called SIRs_081011_WGS84.shp. The dataset was originally in the GCS_WGS_1984 projection. Upon review the GeoPlan Center noted the features did not align with the previous version of the layer (snkhle.shp) already in FGDL. Using the SIRs_081011_WGS84 attribute table's LAT_DEC and LONG_DEC as well as the DATE_ADD and COMMENTS field, GeoPlan was able to determine that the existing spatial location of each feature has shifted 33 meters from the previous correct location. In order to fix this GeoPlan exported the SIRs_081011_WGS84 Attribute table to a separate .DBF and using the ARCGIS Add XY tool with the LAT_DEC and LONG_DEC fields recreated the layer in the GCS_WGS_1984 projection. Next the new dataset was reprojected from it's original projection GCS_WGS_1984 to the FGDL Albers projection. The dataset was renamed to SIR_AUG11.shp The dataset Attribute table was upper cased. The field DESCRIPT was added based on ONAME, features with no DESCRIPT value were calculated to NA. The field FGDLAQDATE was added and populated. Process Date: 20111014
