FLORIDA GEOGRAPHIC DATA LIBRARY DOCUMENTATION

TITLE: ST. JOHNS WATER MANAGEMENT DISTRICT SPRINGS AND SEEPS - 2010

Geodataset Name:       SPRINGS_SJRWMD_2010
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Point
Feature Count:         180
GENERAL DESCRIPTION:
This data layer also includes surficial aquifer springs, which are now called seeps, under nomenclature recently agreed upon by the Florida Geological Survey. A spring is defined as a place where groundwater flows naturally onto the land surface or into a body of surface water. Springs will be derived from lat/longs stored in the Station Header table within the Oracle database; they are the subset of stations that represent springs. Individual representatives of a spring's group (for example, the many springs that make up the Silver Springs group) are each represented by a point, rather than a single point per group. This is an update to the springs_sjrwmd_2007 layer.

FEATURE ATTRIBUTE TABLES CODES AND VALUES:

Item
Item Description
OBJECTID Internal feature number.

SHAPE Feature geometry.

STN_ID A unique feature identifier (numeric) in the SJRWMD's Oracle table, Station Header.

STN_NM Unique official name (text) of the spring.

LAT_NO Decimal Degree Location of Latitude.

LONG_NO Decimal Degree Location of Longitude.

SRCE_OFFCL Source Official Name of the Aquifer that is the source of the spring.

CNTY_ID County ID code.

PNT_LOC_DS Point Location Description. Not unique, not the official name of the spring, this is additional information on the spring/seep entity's location.

STN_CTGRY Whether it is a Spring or Seep.

HISTORICAL Historical Spring Magnitude- Pre-2003 median spring magnitude of all discharge measurements.

SPRING_MAG Magnitude of the spring - it's a value from 1-8, representing median of all discharge measurements for spring.

SPRING_M_1 Spring Magnitude Date- MM/DD/YYYY of last measurement used for the Magnitude median calculation.

COUNTY The county in which the spring/seep is located.

USNG_FL_1K Facility's 1-kilometer United States National Grid (USNG) address. The USNG is an alpha-numeric reference system based on the UTM coordinate system and is similar to the Military Grid Reference System. Use of the USNG ensures a uniform grid mapping and positional reporting system for search and rescue, emergency planning, response, and recovery.

DESCRIPT Based on STN_NM

FGDLAQDATE The date FGDL acquired the data from the source.

AUTOID Unique ID added by GeoPlan

Florida is divided into five water management districts to preserve and manage 
Florida's precious water resources. The St. Johns River Water Management 
Florida is divided into five water management districts to preserve and manage 
Florida's precious water resources. The St. Johns River Water Management 
District is responsible for managing groundwater and surface water resources 
in all or part of 18 counties in northeast and east-central Florida. District staff 
work from service centers in Palatka, Jacksonville, Altamonte 
Springs and Palm Bay

Internal SJRWMD NOTE:

Process involves setting up views and materialized views of the three data models 
on PROD, followed by creating attribute and a final SDE feature view on the SDE 
database (GISLIB account) pointing to these PROD views and the SDE feature 
class GISLIB.STN_ET_GEOM. Any specific questions about the data in this view 
should be directed to the person who originally created the station in Station Header, 
listed with the "Created By:" field when doing a station search in the Station Header 
web app: http://dasprod/station/

Created from SDE feature view of Spring & Seep stations from Station Header on PROD. Request from SJRWMD's 
Groundwater Programs Division (Jill Stokes) to create this GIS view of current spring/seep stations. The 
District uses this information for general mapping and cartographic purposes, and for small and medium 
scale hydrologic and assessment applications.

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
of the materials, either expressly or implied, including but not limited
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,
modifying, contributing or distributing the materials.

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
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
GeoPlan Center Process Steps:
Geoplan downloaded the data from the SJRWMD's GIS data website
(http://www.sjrwmd.com/gisdevelopment/docs/themes.html) on 
January 28, 2011. 

The data downloaded was in shapefile and feature class format packaged 
together in a zip file called springseep.zip.
The shapefile was extracted and originally named: GISLIB_STN_ET_SPRINGSEEP
The data was in the following projection:
NAD_1983_HARN_UTM_Zone_17N

The following tasks were undertaken:
- Reprojected to the FGDL Albers NAD83 HARN projection.
- All records were uppercased.
- Changed original layer name from GISLIB_STN_ET_SPRINGSEEP to 
  SPRINGS_SJRWMD_2010.
- Added and calculated the COUNTY and USNG_FL_1K fields by 
  performing spatial joins. 
- Added the DESCRIPT field based on STN_NM
- Added the FGDLAQDATE based on the date GeoPlan acquired the 
  data from the source.
Process Date: 20110202

Data imported to ArcSDE and exported as a shapefile. Process Date: 20110214
