Item Identification

Title: C-CAP Land Cover, Lower Columbia River Estuary, Oregon, Washington, 2009
Short Name: 2009_or_wa_lcre_ccap_hr_lc
Status: Completed
Publication Date: 2011-07-29
Abstract:

This data set consists of land cover derived from high resolution imagery and was analyzed according to the Coastal Change Analysis Program (C-CAP) protocol. The project area extends from the river's mouth to RM 145 below the Bonneville Dam and from the Columbia River to the historic floodplain boundary. This dataset was developed through a collaboration between the Lower Columbia River Estuary Partnership and the NOAA Office for Coastal Management.

Purpose:

To create a baseline inventory of land cover features which can be utilized by state and local resource managers.

Data Quality

Accuracy:

None.

Horizontal Positional Accuracy:

Horizontal accuracy is 12m at 95% confidence level.

Vertical Positional Accuracy:

There was no terrain correction in the geo-referencing procedure.

Completeness Report:

Data does not exist for all classes. There are no pixels representing class 11 (Mixed Forest), class 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 Developed, High Intensity (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: 628165
Description:

This dataset was created by Sanborn (www.sanborn.com)and NOAA OCM. This version of the classification is the High Resolution Land Cover (2009-era) for the Lower Columbia River. Summary: This section outlines the classification procedure for the Lower Columbia River High Resolution C-CAP. This product was developed through a partnership between the Lower Columbia River Estuary Partnership (LCREP) and the NOAA Office for Coastal Management. The development process occurred in 2 phases. During Phase 1, Sanborn Solutions created a land cover dataset for the lower Columbia River estuary with an emphasis on estuarine and freshwater vegetation and habitats using classification scheme developed specifically for the needs of LCREP. NOAA OCM provided technical assistance and quality assurance services to LCREP and Sanborn. During Phase 2, NOAA OCM took LCREP's final product and retrofitted for addition to the high resolution C-CAP product line. The product was derived from high resolution 4 band digital imagery in combination with LiDAR elevation data. In addition to the primary data sources, many supporting datasets such as archived Landsat imagery, the NWI and a Hydrologic Influence Layer, were used to enhance the classification. The mapping methodology employed an object oriented (image segmentation) approach. Phase 1: The land cover data was generated via object oriented classification. Field data collection was performed by SWCA Environmental Consultants. Image objects (segments) formed the base unit for field data collection and analysis. Sanborn performed an initial automated classification using Classification and Regression Tree (CART) analysis. Additional modeling was performed at the segment level using eCognition. Features that could not be captured successfully through CART or Spatial Models were addressed through manual editing. The final MMU was 0.25 acres. Attributes for the LCREP product are as follows: 10 Coniferous Upland Forest; 11 Deciduous Upland Forest; 21 Coniferous Wetland Forest; 22 Deciduous wetland forest; 40 Upland Shrub-Scrub; 41 Wetland Shrub-Scrub; 50 Upland Herbaceous; 51 Wetland herbaceous; 60 Aquatic Bed; 70 Agriculture; 71 Tree farms; 80 Bare; 81 Mud; 82 Sand; 84 Rock; 90 Urban Impervious; 91 Open Space Developed; 93 Water Phase 2: NOAA OCM utilized the source imagery and the LCREP product to create a High Resolution C-CAP dataset. This involved several steps. 1)Impervious surfaces and Open Spaced Developed were remapped to finer minimum mapping unit (MMU). This involved resegmenting to a finer scale and applying threshold models. The impervious MMU was refined to 0.05 acres. 2)LCREP classes were crosswalked and/or consolidated to C-CAP classes. 3) Modeling in eCognition and Manual edits were applied to LCREP categories that did not exhibit a direct crosswalk. The map maintains a 0.25 acre MMU for non-impervious classes. Attributes for the final C-CAP product are as follows:

0 Background; 1 Unclassified; 2 Impervious; 3; 4; 5 Developed, Open Space; 6 Cultivated Crops; 7 Pasture/Hay; 8 Grassland/Herbaceous; 9 Deciduous Forest; 10 Evergreen Forest; 11 Mixed Forest; 12 Scrub/Shrub; 13 Palustrine Forested Wetland; 14 Palustrine Scrub/Shrub Wetland; 15 Palustrine Emergent Wetland; 16 Estuarine Forested Wetland; 17 Estuarine Scrub/Shrub Wetland; 18 Estuarine Emergent Wetland; 19 Unconsolidated Shore; 20 Bare Land; 21 Open Water; 22 Palustrine Aquatic Bed
