Description:

Abstract:

Land cover and land use in the St. Johns River Water Management District based on 2004 Natural color

and color infrared aerial photography.

Purpose:

This data layer was developed to support many of the District's critical projects or programs, including

Pollution Load Reduction Goal Development, Land Acquisition, Land Management, Water Supply

Planning, Floodplain Management, and Surface and Groundwater Quality Monitoring.

Wetlands identified in this layer should only be used for general reference, not for legal purposes or

detailed analysis. Local determinations always require field inspection.

Supplemental_Information:

The source imagery was obtained from December 2003 to March 2004 and used to produce

orthophotos with a one meter ground resolution. Imagery was acquired at 0.62 meter ground sample

distance (GSD) resolution. Flight height maintained during mission was 20,000 feet AGL. The imagery

was captured at 12-bit radiometric resolution and converted to 8-bit radiometric resolution during post

processing. The imagery was captured with 20% sidelap between all adjacent flight lines. The

SJRWMD project area was divided into 5 flight blocks due to necessary base station and flight line

length requirements. The imagery was obtained and processed by all digital means beginning with data

acquisition using a Leica ADS40 Digital Airborne Sensor. The orthophotos are available in GeoTIFF

form. The projected coordinate system is UTM zone 17 N, NAD 83 HARN, GRS 80, Units Meters.

Horizontal_Positional_Accuracy_Report:

This layer is based upon 2004 digital orthophoto quarterquads. Digital orthophoto quadrangles

and quarter-quadrangles must meet horizontal National Map Accuracy Standards (NMAS) at

1:24,000 scale and 1:12,000 scale, respectively. The NMAS specify that 90 percent of the

well-defined points tested must fall within 40 feet (1/50 inch) at 1:24,000 scale and 33.3 feet

(1/30 inch) at 1:12,000 scale.

To create the data, the orthorectified images were displayed on a computer screen at varying

scales of about 1:12,000 or less.

Source_Information:

Source_Citation_Abbreviation: SJRWMD 2000 Land Use / Land Cover

Source_Contribution:

The 2004 layer is based on the 2000 land use / land cover layer, with revisions made to

accomodate: a) thematic changes dictated by updates to the PI Key and classification system,

and b) thematic and boundary changes indicated by the 2004 DOQQs.

Process_Step:

Process_Description:

The following steps were conducted onsite by staff of Kyra InfoTech, Inc, to create the 2004

layer. See Statement of work and purchase order specifications (District Purchase order #

PO038177) for further details. 1. For each DOQQ, the photointerpreters will create a 2004 layer

by modifying a copy of the 2000 layer according to thematic and boundary changes indicated by

the 2004 DOQQs. 2. All mapping shall be from screen digitizing color-infrared (CIR) 3.75' Digital

Orthophoto Quarter Quadrangles (DOQQ), in ArcGIS 9, with an adjacent digital stereo capable

imagery and software for inspecting the digital imagery. 3. All mapping shall be conducted while

consulting the ancillary data. 4. All classification will be in keeping with specifications listed in

the PI Key. If the PI Key is unclear or incorrect, or if the photointerpreters have questions

regarding appropriate classification, the internal District photointerpreter will make the decision.

5. The 2004 layer will have two land use classification items: LCCODE and LUCODE. LCCODE

will be used for land cover, while LUCODE will be used for land use; item values will differ only

when land use and land cover for any given polygon differ. Detailed guidelines for application of

this dual coding scheme are discussed in the PI Key.

The contract was initiated Sept. 2004, work began November 2004, and work Sept 2006.

Adapting the use of Geodatabase for update and editing of data as well as technical issues with

software and hardware slowed the project down in its early phases.

Process_Date: September 30, 2006

Process_Step:

Process_Description:

All phases were QA'ed by the SJRWMD photointerpretation specialist. Comments were sent to

the photointerpreter(s) who then revised the data accordingly.

Process_Date: September 30, 2006

Process_Step:

Process_Description:

Spatial data was checked for topology errors against the following rules:

No gaps between polygons No overlapping polygons

A cluster tolerance of 0.05 meters was used.

Where substantial overlaps or gaps existed, an SJRWMD photointerpretation specialist was

consulted and the errors corrected.

Process_Date: October 2006

Process_Step:

Process_Description:

The Land Use/Land Cover code combinations were checked for all features against the modified

FLUCCS code. Illegal code combinations were corrected.

Process_Date: October 2006

Process_Step:

Process_Description:

The landuse/land cover data in quarter quad areas around the periphery of the SJRWMD

boundary were checked for completeness. If changes to the LULC data for the quarter quad

were a result of changes to features shared by complete, neighboring quarter quad data, the

features for the quarter quad in question were clipped and deleted.

Overview_Description:

Entity_and_Attribute_Overview:

The coding scheme is a modified Florida Land Use/Land Cover and Forms Classification System

(FLUCCS). A detailed discussion of the coding scheme can be found in the SJRWMD 2000

Photointerpretation Key. The PI Key lists each class used in the 2004 land use / land cover layer, along

with a detailed description, keys to photointerpretation, a list of similar classes, special mapping

conventions if they exist, a sample DOQ image, and a field picture. SJRWMD staff may access the PI

Key through GISDOC (Data, Data Users Guides).

See below for a discussion of the use of LUCODE vs. LCCODE.

Following is a list of valid LCCODE and LUCODE values. * Codes marked with an asterisk are not

used for classification and are listed only for clarification.

*** LUCODE VS. LCCODE *** Each feature is required to have two attributes, one emphasizing land

cover (LCCODE) and the second land use (LUCODE). In most cases, these two values are the same.

They differ in a minority of cases where separate cover and use values are required in order to

adequately describe the mapping unit. The result is a map with dual codes. The LCCODE attribute can

be used (mapped, queried, etc.) alone for a land cover emphasis; LUCODE can be used alone for a land

use emphasis; or both can be used together.

Any polygon described by the following LUCODE values must be assigned a different LCCODE value:

1180 - Rural residential (2-5 acres per dwelling unit) 1650 - Reclaimed mining lands 1670 - Abandoned

mining lands 1900 - Open land (urban) 1920 - Inactive land with street pattern but no structures (urban)

2600 - Other open lands (rural)

Any polygon described by the following LCCODE values must be assigned a different LUCODE value:

8340 - Wastewater treatment 8360 - Other treatment ponds (non-sewage). In this case, the LUCODE

must be populated with the associated land use or purpose of the ponds, e.g. dairy (2520) or cattle

feeding operation (2310).

Polygons described by the following LUCODEs may at the discretion of the photointerpreter have

differing values for LUCODE and LCCODE: 1700 - Institutional 1730 - Military 1750 - Governmental

(Kennedy Space Center only) 1800 - Recreational 1850 - Parks and zoos 2240 - Abandoned tree crops

2310 - Cattle feeding operations 2320 - Poultry feeding operations 2500 - Specialty farms 2510 - Horse

farms 2520 - Dairies 8350 - Solid waste disposal
