Abstract:
***2004 Florida Cropland Data Layer specific information*** The processing for the Florida CDL differed from the other 2004 CDLs. Firstly, the Florida CDL used additional citrus training/validation data provided by the Florida NASS Field Office. The Citrus Grove Data Layer is confidential and for internal NASS use only. The second major difference in processing is that special processing was required to properly identify sugarcane. This included photo intrepretation to identify additional sugarcane training data and to limit the spatial extent of the sugarcane area.
The USDA-NASS 2004 Florida Cropland Data Layer (CDL) is a raster, geo-referenced, categorized land cover data layer produced using satellite imagery from the Thematic Mapper (TM) instrument on Landsat 5 and Enhanced Thematic Mapper Plus (ETM+) on Landsat 7 (GAP Filled) with the emphasis being agricultural land cover. The imagery was collected between the dates of 04/03/2004 and 11/29/2004. The approximate scale is 1:100,000 with a ground resolution of 30 meters by 30 meters. The Florida Program represents a cooperative venture between three USDA Agencies (headquarters units of NASS, the Foreign Agriculture Service, and the Farm Service Agency) plus an in-state agreement with the Florida Agricultural Statistics Service.
Some CDL states used additional satellite imagery and ancillary inputs to supplement and improve the classification. These additional sources can include the United States Geological Survey (USGS) National Elevation Dataset (NED), the USGS National Land Cover Database 2001 (NLCD 2001), and the National Aeronautics and Space Administration (NASA) Moderate Resolution Imaging Spectroradiometer (MODIS) 250 meter 16 day Normalized Difference Vegetation Index (NDVI) composites.
Agricultural training and validation data were derived from the extensive field observations collected during the annual NASS June Agricultural Survey and from the Farm Service Agency (FSA) Common Land Unit (CLU) Program. The NLCD 2001 is used as non-agricultural training and validation data.
Please refer to the 'Supplemental_Information' Section of this metadata file for a complete list of all imagery, ancillary data, and training/validation data used to generate this state's CDL.
The strength and emphasis of the CDL is agricultural land cover. Please note that no farmer reported data are derivable from the Cropland Data Layer.
Purpose:
The purpose of the Cropland Data Layer Program is to use satellite imagery to (1) provide acreage estimates to the Agricultural Statistics Board for the state's major commodities and (2) produce digital, crop-specific, categorized geo-referenced output products.

Native_Data_Set_Environment:
The hardware requirements for processing this data set are as follows: for digitizing/ground truth editing, any of the 32 bit Microsoft OS's will work. For computationally intensive jobs including; scene processing, clustering, classification, estimation and mosaicking a batch type system is utilized where jobs can be queued on different devices, and the minimum requirements are NT/2000/XP.Image processing is typically performed using PEDITOR, where PEDITOR utilizes the Windows console along with environmental variables, and neither are available with 95/98. PEDITOR as it is now constituted, will only run under the Microsoft Windows operating systems.The 2004 Florida Cropland Data Layer was created using Rulequest's See5.0 software rather than NASS' Peditor in-house software. All available raw Landsat imagery for the region was used as input along with the non-agricultural portion of the United States Geological Survey's 2001 National Land Cover Data. More information on Rulequest's See5.0 software can be found at <http://www.rulequest.com/>.A Microsoft Visual FoxPro application called the Remote Sensing Project or RSP is used to manage the ground truth collection process, and track each segment to its completion.Commercial off the shelf software XLNT from Advanced Systems Concepts, allows for batch job processing on the NT/2000/XP operating systems. SARS utilizes XLNT to run computationally intensive jobs that are shared across network resources to expedite processing. Additional information about XLNT can be found at <http://www.advsyscon.com/>.In 2005, NASS began testing the use of Rulequest's See5.0 software rather than PEDITOR. Check the "Process_Description" section of this metadata file for more details on which methodology was used for this specific state and year. Additional information on Rulequest's See5.0 software can be found at <http://www.rulequest.com/>.Leica Geosystems ERDAS Imagine and ESRI's ArcGIS are often used in the pre- and post-processing of data. Additional information about Leica Geosystems ERDAS Imagine software can be found at <http://gi.leica-geosystems.com/>. Additional information about ESRI's ArcGIS software can be found at <https://www.esri.com/>.

NOTE: Accuracy statistics are reported for agricultural areas within the entire state rather than by individual Analysis District. Accuracy statistics for the NLCD categories are not included.
The producer's accuracy relates to the probability that a reference sample will be correctly mapped and measures the errors of omission. In contrast, the user's accuracy indicates the probability
that a sample from a land cover map actually matches what it is from the reference data and measures the error of commission.

Quantitative_Attribute_Accuracy_Assessment:
Attribute_Accuracy_Value:
Classification accuracy is generally 85% to 95% correct for the major crop-specific land cover categories. See the 'Attribute Accuracy Report' section of this metadata file for the detailed accuracy report.
Attribute_Accuracy_Explanation:
The accuracy of the land cover classifications are evaluated using the extensive training data collected in the annual NASS June Area Survey (JAS) and/or the annual Farm Service Agency's (FSA) Common Land Unit (CLU) data. More information about FSA CLUs can be found at <https://www.fsa.usda.gov/> and <https://datagateway.nrcs.usda.gov/>.The June Agricultural Survey is a national survey based on a stratified random sample of land areas selected from each state's area frame. An area frame is a land use stratification based on percent cultivation. Additional information about NASS' June Area Survey can be found at <https://www.nass.usda.gov/Surveys/June_Area/>.Please note that no farmer reported data is derivable from the Cropland Data Layer.
The strength and emphasis of the CDL is crop-specific land cover categories. The accuracy of the CDL non-agricultural land cover classes is entirely dependent upon the USGS, National Land Cover Database (NLCD 2001). Thus, the USDA, NASS recommends that users consider the NLCD for studies involving non-agricultural land cover.
These definitions of accuracy statistics were derived from the following book: Congalton, Russell G. and Kass Green. Assessing the Accuracy of Remotely Sensed Data: Principles and Practices. Boca Raton, Florida: CRC Press, Inc. 1999. The 'Producer's Accuracy' is calculated for each cover type in the ground truth and indicates the probability that a ground truth pixel will be correctly mapped (across all cover types) and measures 'errors of omission'. An 'Omission Error' occurs when a pixel is excluded from the category to which it belongs in the validation dataset. The 'User's Accuracy' indicates the probability that a pixel from the CDL classification actually matches the ground truth data and measures 'errors of commission'. The 'Commission Error' represent when a pixel is included in an incorrect category according to the validation data. It is important to take into consideration errors of omission and commission. For example, if you classify every pixel in a scene to 'wheat', then you have 100% Producer's Accuracy for the wheat category and 0% Omission Error. However, you would also have a very high error of commission as all other crop types would be included in the incorrect category. The 'Kappa' is a measure of agreement based on the difference between the actual agreement in the error matrix (i.e., the agreement between the remotely sensed classification and the reference data as indicated by the major diagonal) and the chance agreement which is indicated by the row and column totals. The 'Conditional Kappa Coefficient' is the agreement for an individual category within the entire error matrix.

Horizontal_Positional_Accuracy_Report:
The categorized images are co-registered to MDA Federal Inc's ortho-rectified GeoCover Stock Mosaic images using automated block correlation techniques. The block correlation is run against band two of each original raw satellite image and band two of the GeoCover Stock Mosaic. The resulting correlations are applied to each categorized image, and then added to a master image or mosaic using PEDITOR. The MDA Federal Inc images were chosen as they provide the best available large area ortho-rectified images as a basis to register large volume Landsat images with.

Process_Step:
Process_Description:
***2004 Florida Cropland Data Layer specific information*** The processing for the Florida CDL differed from the other 2004 CDLs. Firstly, the Florida CDL used additional citrus training/validation data provided by the Florida NASS Field Office. The Citrus Grove Data Layer is confidential and for internal NASS use only. The second major difference in processing is that special processing was required to properly identify sugarcane. This included photo intrepretation to identify additional sugarcane training data and to limit the spatial extent of the sugarcane area.
The Cropland Data Layer (CDL) Program provides the National Agricultural Statistics Service (NASS) with internal proprietary county and state level acreage indications of major crop commodities, and secondarily provides the public with "statewide" (where available) raster, geo-referenced, categorized land cover data products after the public release of county estimates. This project builds upon NASS' traditional crop acreage estimation program, and integrates enumerator collected ground survey data and/or Farm Service Agency field data with satellite imagery to create an unbiased statistical estimator of crop area at the state and county level for internal use. Please note that in no case is farmer reported data revealed or derivable from the public use Cropland Data Layer. The 2004 Florida Cropland Data Layer was developed using Leica Geosystems ERDAS Imagine in tandem with Rulequest See5.0. Both are commercial software packages. ERDAS Imagine, being a comprehensive image processing suite, handled the bulk of the processing steps including preprocessing and managing of the raw imagery and training data, building of the scene classifications, and creation of the final statewide mosaics. See5.0 was solely used to derive the classification rules, based on training data, for which ERDAS Imagine then applies back to the input imagery. Broadly defined, See5.0 is a niche data mining tool that derives decision trees, or a set of if-then rules, to assemble data into categories. It is not a GIS application in itself.Decision trees offer several advantages over the more traditional maximum likelihood classification method. The advantages include being: 1) non-parametric by nature and thus not reliant on the assumption of the input data being normally distributed, 2) efficient to construct and thus capable handling large and complex data sets, 3) able to incorporate missing and non-continuous data, and 4) able to sort out non-linear relationships. These reasons combined usually lead to improved classifications over the maximum likelihood method. Additionally, there are several varieties of decision tree classifiers but See5.0 stands out because it further employs a statistical technique known as "boosting" which has been shown to improve results even further. More information on Rulequest's See5.0 software can be found at <http://www.rulequest.com/>.As with the maximum likelihood method, decision tree analysis is a supervised classification technique. Thus, it relies on having a sample of known ground truth areas in which to "train" the classifier. In turn, the classifier can then "learn" how to most reasonably place into a category the rest of the unknown pixels. The best ground truth comes from a statistically representative probability sample that is dense enough to account for the variability of the land cover types that are being mapped. Traditionally, NASS CDLs have utilized ground truth data from the annual June Agricultural Survey (JAS). More information about the JAS can be found at <https://www.nass.usda.gov/Surveys/June_Area/>. To make this survey data available for use within a classification takes a fair amount of labor because the field boundaries and attributes have to be manually digitized into a GIS since natively they are recorded only on paper. More recently, very comprehensive ground truth data has been provided from the Farm Service Agency (FSA) which NASS has begun utilizing as a replacement for the JAS information. The FSA data has the advantage of natively being in a GIS and containing magnitudes more of field level information. Disadvantages include it is not truly a probability sample of land cover and has bias toward subsidized "program" crops. Additional information about the FSA data can be found at <https://www.fsa.usda.gov/> and <https://datagateway.nrcs.usda.gov/>.All available raw satellite imagery for the region was used as input along with the non-agricultural portion of the United States Geological Survey's (USGS) 2001 National Land Cover Data (NLCD). Additional information on the USGS NLCD can be found at <https://www.mrlc.gov/>.Scene selection begins in early summer, and could run into the late fall depending on image availability. The Cropland Data Layer program primarily uses the Landsat TM or IRS AWIFS platform for acreage estimation. However, other platforms such as Spot or gap-filled Landsat ETM+ are used to fill "data acquisition" holes within a state. A spring and summer date of observation is preferred for maximum crop cover separation for multi-temporal analysis of summer crops. If only one date of observation is available (unitemporal), a mid summer date is preferred. If only an early spring date March-May or a fall date September-October is available (unitemporal) during the growing season, then it is best to not use that scene or analysis district for estimation, as bare soil in the spring and fully senesced crops in the fall will provide erroneous results.For estimation purposes, clouds can be minimized by defining Analysis Districts (AD) along adjacent scene edges, by cutting the Analysis Districts by county boundary, or cutting the clouds out by primary sampling units. Analysis Districts can be individual or multiple scenes footprints that have to be observed on the same date, and analyzed as one. An AD can be comprised of one or more scenes. An AD can be defined by either a scene edge or a county boundary. Multi-temporal AD's are possible as long as both dates in all scenes are the same. A single or multi-scene AD will use all potential training fields for clustering/classification/estimation. Several factors can lead to problems in a classification, some get corrected in early edits and some do not.Several factors can lead to problems in a classification, some get corrected in early edits and some do not: poor imagery dates, with respect to the major crops of interest, incomplete or incorrect the ground truth, irrigation ditches, wooded areas, low spots filled with water, and/or bare soil areas in an otherwise vegetated field. Crops that look alike to the clustering algorithm(s) due to planting/growing cycle: spring wheat and barley at almost any time, crops in senescence, and grassy waste fields and idle cropland. Cover types that are essentially the same but used differently: wooded pasture versus woods or waste fields (only difference may be the presence of livestock), corn for grain versus corn silage, and cover crops such as rye and oats. Cover types that change signatures back and forth during the growing season: alfalfa and other hays before and after cutting, with multiple cuttings per year.Each categorized scene is co-registered to MDA Federal Inc's GeoCover LC imagery (50 meters RMS), and then stitched together using Peditor's Batch program. A block correlation is run between band two from each raw scene, and band two of the ortho-base image. The registration of the GeoCover mosaicked scene and the individual raw input scenes are used to get an approximate correspondence. A correlation procedure is used on the raw scenes and the mosaicked scene to get an exact mapping of each pixel from the input scenes to the mosaicked scene. The results of the correlation are used to remap the pixels from the individual input scenes into the coordinate system of the mosaicked scene. The mosaic process now performs: 1) Precision registration of images automatically, 2) Converts each categorized image and associated statistics file to a set standard automatically (recode), 3) Specify overlap priority by scene or county, 4) Filters out clouds when possible. The scenes are stitched together using the priorities previously assigned from the scene observation dates/analysis districts map. Scenes/analysis districts with better quality observation dates are assigned a higher priority when stitching the images together. Clouds are assigned a null value on all scenes, and scenes of lower priority that are cloud free, take precedence over clouded higher priority images. Once cloud cover is established throughout the mosaic the clouds are assigned a digital value.The Cropland Data Layer products contain imagery in GEOTIFF image file format.All CDL distribution for the previous crop year is held until the release of the official NASS county estimates for the major commodities grown within a given state. Corn and Soybeans are released in March for the previous crop year - Midwestern States. Rice and Cotton are released in June for the previous crop year - Delta States. Small grains are released in March for the Great Plains States.NASS publishes all available accuracy statistics for end-user viewing. The Percent Correct is calculated for each cover type in the ground truth, it shows how many of the total pixels were correctly classified (i.e. across all cover types). 'Commission Error' is the calculated percentage of all pixels categorized to a specific cover type that were not of that cover type in the ground truth (i.e. incorrectly categorized). CAUTION: a quoted Percent Correct for a specific cover type is worthless unless accompanied by its respective Commission Error. Example: if you classify every pixel in a scene to 'wheat', then you have a 100% correct wheat classifier (however its Commission Error is also almost 100%). The 'Kappa Statistic' is an attempt to adjust the Percent Correct using information gained from the confusion matrix for that cover type.The NASS CDL Program is continuing efforts to reduce end-user burden, increase functionality, and take advantage of enhancements in computer technology.

Overview_Description:
Entity_and_Attribute_Overview:
The Cropland Data Layer (CDL) is produced using agricultural training data from the annual NASS June Area Survey (JAS) and/or the annual Farm Service Agency's (FSA) Common Land Unit (CLU) data and non-agricultural training data from the United States Geological Survey (USGS) National Land Cover Database 2001 (NLCD 2001). The strength and emphasis of the CDL is crop-specific land cover categories. The accuracy of the CDL non-agricultural land cover classes are entirely dependent upon the NLCD. Thus, the USDA, NASS recommends that users consider the NLCD for studies involving non-agricultural land cover.

 ***NOTE: The 1997-2013 CDLs were recoded and re-released in January 2014 to better represent pasture and grass-related categories. A new
 category named Grass/Pasture (code 176) collapses the following historical CDL categories: Pasture/Grass (code 62), Grassland Herbaceous
 (code 171), and Pasture/Hay (code 181). This was done to eliminate confusion among these similar land cover types which were not always
 classified definitionally consistent from state to state or year to year and frequently had poor classification accuracies. This follows
 the recoding of the entire CDL archive in January 2012 to better align the historical CDLs with the current product. For a detailed list
 of the category name and code changes, please visit the Frequently Asked Questions (FAQ's) section at <https://www.nass.usda.gov/Research_and_Science/Cropland/sarsfaqs2.php>.
