Description:

Abstract:

The GAP National Terrestrial Ecosystems – Ver 3.0 is a 2011 update of the National
Gap Analysis Program Land Cover Data – Version 2.2 for the conterminous U.S. The GAP
National Terrestrial Ecosystems – Version 3.0 represents a highly thematically detailed land
cover map of the U.S. The map legend includes types described by NatureServe’s Ecological
Systems Classification (Comer et al. 2002) as well as land use classes described in the
National Land Cover Dataset 2011 (Homer et al. 2015). These data cover the entire
continental U.S. and are a continuous data layer. These raster data have a 30 m x 30 m cell
resolution. GAP used the best information available to create the land cover data; however
GAP seeks to improve and update these data as new information becomes available.

Purpose:

The mission of the USGS Gap Analysis Program (GAP) is to provide state, regional and
national biodiversity assessments of the conservation status of native vertebrate species
and natural land cover types and to facilitate the application of this information to land
management activities. The goal of GAP is to keep common species common by identifying
species and plant communities not adequately represented in existing conservation lands.
Common species are those not currently threatened with extinction. By providing these data,
land managers and policy makers can make better-informed decisions when identifying priority
areas for conservation. The U.S. Geological Survey National Gap Analysis Program Land Cover
Data is complete for the conterminous United States. The national coverage has been clipped
to each of the 50 states, the 21 Landscape Conservation Cooperatives and 6 regions.This data
may represent one of these subsets.

Inappropriate Uses: It is far easier to identify appropriate uses than inappropriate
ones, however, there is a "fuzzy line" that is eventually crossed when the differences in
resolution of the data, size of geographic area being analyzed, and precision of the answer
required for the question are no longer compatible. Examples include:
– Using the 2001 and 2011 land cover data sets to quantify change (see Data Use Constraints).
-Using the data to map small areas (less than thousands of hectares), typically requiring mapping
resolution at 1:24,000 scale and using aerial photographs or ground surveys.
-Combining these data with other data finer than 1:100,000 scale to produce new hybrid maps or answer
queries.
-Generating specific areal measurements from the data finer than the nearest
thousand hectares
-Establishing exact boundaries for regulation or acquisition.
-Establishing definite occurrence or non-occurrence of any feature for an exact geographic
area
-Determining abundance, health, or condition of any feature.
-Establishing a measure of accuracy of any other data by comparison with GAP data.
-Altering the data in any way and redistributing them as a GAP data product.
-Using the data without acquiring and reviewing the metadata.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:

Throughout the land cover update process a series of reviews were conducted by the
National Gap Analysis Program analysts. Visual checks were done against high resolution
imagery accessed through Google Earth and ArcGIS base maps to assess the ground condition
for the 2011 time period. Areas of focus were those where the National Land Cover Dataset
class did not match the generalized GAP Land Cover (e.g. a forested ecological system
dominated by evergreen species where NLCD had mapped deciduous forest) and those areas where
the LANDFIRE disturbance layer indicated a moderate to severe disturbance had occurred. For
each geoarea one analyst was responsible for the update and a second reviewed each of the
land cover classes in the final updated dataset for the area. Once the updates were complete
the 2011 land cover dataset was created by mosaicing the individual files into a single
image. A class by class review of was then conducted to look for consistency in extent and
pattern for each of the 584 mapped classes. Where anomalies were identified a second review
was conducted to determine the potential source of the errors. Each class flagged in that
review was checked by a second analyst to determine the source of the errors and to rerun
the decision rules when needed. The initial land cover being updated, the mosaic for the
2001 National Gap Analysis Land Cover Ver 2 had undergone expert review in addition to
formal accuracy assessments for the Northwestern United States and the Southwestern portions
of the dataset. The full 2001 land cover had undergone similar class by class review both
during the creation of the regional maps, as well as after the full mosaic had been
created.

Logical_Consistency_Report:

The dataset has been extensively reviewed for logical accuracy by creating combinations
of the updated land cover datasets with initial dataset (the 2001 National Gap Analysis Land
Cover Dataset) and at each major step in the process to track which classes were being
impacted by each decision rule. If map classes that were not logically changed by the decision
rule changed, that information was used to track flaws in the scripts used to apply the
rules.

Completeness_Report:

A series of comparisons with regional or local datasets have been conducted throughout
the development of the initial 2001 Land Cover map and throughout the updating process. Given
the fact that the Ecological Systems Classification, the basis for the map legend in the
vegetated areas, was under development while some of the areas were being mapped, the concepts
represented in the map are specific to the concept at the time the mapping was conducted.
Combinations of the Ecological Systems mapped distribution and range maps for those systems
have been created to identify map units in which further review and refinement would be useful
for refining future detailed land cover maps.

Horizontal_Positional_Accuracy_Report:

Checking of the location of pixels relative to the National Land Cover Dataset and
LANDFIRE Existing Vegetation Dataset was done for multiple locations throughout the
conterminous U.S. in each case the pixels were within 15 meters of the placement of the
pixels in the NLCD. The final dataset was snapped so that it aligns with the other
national datasets.

Inappropriate Uses: It is far easier to identify appropriate uses than inappropriate
ones, however, there is a "fuzzy line" that is eventually crossed when the differences in
resolution of the data, size of geographic area being analyzed, and precision of the answer
required for the question are no longer compatible. Examples include:
– Using the 2001 and 2011 data to quantify change (see Data Use Constraints).
-Using the data to map small areas (less than thousands of hectares), typically requiring mapping resolution at 1:24,000 scale and using aerial photographs or ground surveys.
-Combining these data with other data finer than 1:100,000 scale to produce new hybrid maps or answer queries.
-Generating specific areal measurements from the data finer than the nearest thousand hectares
-Establishing exact boundaries for regulation or acquisition.
-Establishing definite occurrence or non-occurrence of any feature for an exact geographic area
-Determining abundance, health, or condition of any feature.
-Establishing a measure of accuracy of any other data by comparison with GAP data.
-Altering the data in any way and redistributing them as a GAP data product.
-Using the data without acquiring and reviewing the metadata.
