Item Identification

Title: C-CAP Land Cover, New Orleans Area Parishes, Louisiana, 2017
Status: Completed
Publication Date: 2021-12-08
Abstract:

The NOAA Coastal Change Analysis Program (C-CAP) produces national standardized land cover and change products for the coastal regions of the U.S. C-CAP products inventory coastal intertidal areas, wetlands, and adjacent uplands with the goal of monitoring changes in these habitats through time. The timeframe for this metadata is summer 2016. These maps are developed utilizing high resolution aerial imagery, along with lidar and various available ancillary information, and can be used to track changes in the landscape through time. This trend information gives important feedback to managers on the success or failure of management policies and programs and aid in developing a scientific understanding of the Earth system and its response to natural and human-induced changes. This understanding allows for the prediction of impacts due to these changes and the assessment of their cumulative effects, helping coastal resource managers make more informed regional decisions.

Purpose:

C-CAP is dedicated to the development, distribution, and application of land cover and change data for the coastal regions of the U.S.

Open Space Developed (93.4%, 95.0%)

Cultivated (92.3%, 100%)

Pasture/Hay (100%, 97.6%)

Grassland (72.3%, 94.4%)

Upland Forest (95.2%, 95.2%)

Shrub/Scrub (89.2%, 71.7%)

Palustrine Forested Wetland (97.5%, 96.3%)

Palustrine Shrub/Scrub Wetland (94.1%, 87.3%)

Palustrine Emergent Wetland (95.1%, 95.1%)

Ice/Snow (NA, NA)

Overall accuracy (93.5%)

Points were sampled using a stratified random sampling scheme, with a minimum target sample of 20 points per class. A few of the rarer categories did not meet this minimum threshold or were not sampled at all due to the relatively low total area of those classes. There were no pixels sampled for the Estuarine Forested Wetland class. The correct land cover classification was determined through analyst interpretation of the imagery used in creating the map, as well as possible references to GoogleEarth in order to reference additional dates/seasons of imagery for that location. All points were interpreted by two analysts, plus a third who made a final determination when there was not agreement on the call. This analysis allowed for the use of fuzzy designations, or alternate calls he truth category where that truth call may not have been completely obvious, or where point locations are located so they could possibly be more than one category. 37 of the total 842 points were counted correct based on the use of that fuzzy call.

Completeness Report:

Data does not exist for all classes.

There are no pixels representing: class 1 (unclassified), class 9 (Deciduous Forest), 101 (Evergreen Forest), , 24 (Tundra), 25 (Perennial Ice/Snow), 26 (Dwarf Scrub - Alaska specific class), 27 (Sedge/Herbaceous), and 28 (Moss - Alaska specific). Developed classes have been altered to exclude the percentage breakdown of impervious surfaces as the breakdown is not appropriate for high resolution mapping (Developed High Intensity (2), Developed Medium Intensity (3), and Developed Low Intensity (4) are reduced to Impervious (Class 2)).

Conceptual Consistency:

Tests for logical consistency indicate that all row and column positions in the selected latitude/longitude window contain data. Conversion and integration with vector files indicates that all positions are consistent with earth coordinates covering the same area. Attribute files are logically consistent.

Process Steps

Process Step 1

CC ID: 1096159
Description:

This dataset was created by NOAA's Ocean Service, Office for Coastal Management (OCM).

Classification: The initial 1m spatial resolution 6 class high resolution land cover product was developed by Ecopia using a proprietary feature recognition technology. This involves taking each image and classifying the pixels based on spectral and spatial properties, based on training examples and analyst refinement.

Water Refinement: Commission and omission errors associated with the Water class were addressed through manual interpretation and clean up in ERDAS Imagine. Once the review and edits were complete, the refined Water class was incorporated back into the land cover data set.

Agriculture and Open Space Developed: Cultivated land, and Pasture/Hay, and Open Space Developed features were incorporated into the grassland category of the initial land cover product through a the use of a second CNN classification, subsequent modeling (based on the presence of impervious cover and ancillary information such as the USDA 2008 Common Land Unit data), and manual refinement.

Wetlands: Wetlands were derived through a modeling process which used ancillary data such as Soils (SSURGO), the National Wetlands Inventory (NWI) and topographic derivatives. Forest, shrub and grassland objects within the initial land cover that exhibited hydric characteristics based on the input ancillary layers were designated to their appropriate wetland category. The process relied mainly on the NWI to determine palustrine and estuarine distinctions.
