The primary data sources include the following: a) 2009 4 band, 1 meter resolution airborne imagery acquired by the USDA National Agriculture Inventory Program (NAIP); b) archived 30m LandSAT TM5 imagery from various dates ranging from 2007-2009; c) 2009-2010 LiDAR elevation data aquired by the US Army Corps of Engineers. The minimum mapping unit, defined as the smallest specified area for mapping an individual landform, is 0.25 acres. Purpose: To create a baseline inventory of land cover features which can be utilized by state and local resource managers.

This version of the classification is the High Resolution Land Cover (2007-era) for the Lower Columbia River Estuary of Oregon and Washington, United States. This section outlines the classification procedure for the Lower Columbia River Estuary high resolution data set. 2009 4-band NAIP aerial imagery (scenes acquired June-August 2009) were used in producing this land cover product. In conjunction with the NAIP mosaic, Sanborn used archived LandSAT TM 5 from 2007-2009, and LiDAR collected by the US Army Corps of Engineers from Dec 2009 - Feb 2010. ((((((((((((((((((((((( Steve to review process description outlined here: The mapping approach utilized an image segmentation and CART statistical approach developed by Sanborn for the NOAA -CCAP high resolution mapping products. A calibration visit was conducted and training data was collected for classification. Non impervious features were mapped using a 0.25 acre minimum mapping unit (MMU). Pre-processing steps: All NAIP and LandSAT scenes used in the classification were selected based on image acquisition times relative to tidal fluctuations in the estuary. In order to map the maximum amount of landforms, images were selected that coincided with low tidal intervals, wherever possible. The NAIP Imagery was provided to Sanborn as a geo-referenced product. Sanborn perfomed a quality control on the imagery to check for pixel dropouts and other image issues. Individual image tiles were combined to create a single mosaic for the entire island. An atmospheric and radiometric correction procedure was applied to selected LandSAT imagery. LiDAR data was provided to Sanborn as pre-processed bare earth and first return models. These were used to generate a raster of estimated canopy heights. Field-Collected Data: Training data was collected in the field between March 15th and Septmeber 30, 2010. Land cover observations were recorded by analysts. Additional training samples were acquired from pre-existing land cover observations. All training samples went through a QA/QC procedure to ensure it met accuracy standards. Classification: Segmentation - Image segmentation was completed at multiple scales using the multispectral NAIP imagery, in conjunction with LIDAR, in order to group like spectral and textural objects within the imagery. For consistency, the associated impervious data set was incorporated into the segmentation layer as a boundary delimiter. Segments can share boundaries of an impervious surface, but can never overlap an impervious surface. Automated Classification - Logical rulesets and thresholding based on the spectral properties of the imagery, and ancillary data, were used to generate an initial draft classification. Automated Classification Refinement - Models were built to refine or reclassify land cover areas by utilizing the wealth of attribute information linked to each segment within Definiens. Classification Edits - As with any automated or semi-automated land cover classification there are often inconsistencies in the land cover map. The final step before map finalization was to remove inaccuracies through manual segment labeling as interpreted by an analyst. Map Finalization - Sanborn used independent reviewer's comments to further refine the land cover map. end classification process )))))))))))))))))))))))))))))))))))) Attributes for this product are as follows: 10 coniferous upland forest 11 deciduous upland forest 23 coniferous wetland forest - non-tidal 24 coniferous wetland forest - tidally influenced 25 coniferous wetland forest - tidally impaired 26 deciduous wetland forest - non-tidal 27 deciduous wetland forest - tidally influenced 28 deciduous wetland forest - tidally impaired 40 upland shrub-scrub 42 wetland shrub-scrub - non-tidal 43 wetland shrub-scrub - tidally influenced 44 wetland shrub-scrub - tidally impaired 50 upland herbaceous 52 wetland herbaceous - non-tidal 53 wetland herbaceous - tidally influenced 54 wetland herbaceous - tidally impaired 60 aquatic bed 70 agriculture 71 tree farms 80 bare 81 mud 82 sand 84 rock 90 urban, impervious surface 91 urban, open space developed 93 water Process_Date: 20110505 Process_Contact: Contact_Information: Contact_Person_Primary: Contact_Person: Keith Marcoe Contact_Organization: Lower Columbia River Estuary Partnership (LCREP) Contact_Position: Data/GIS Manager Contact_Address: Address_Type: mailing and physical Address: 811 SW Naito Parkway, suite 410 City: Portland State_or_Province: OR Postal_Code: 97204 Country: USA Contact_Voice_Telephone: 503-226-1565 x230 Contact_Facsimile_Telephone: 503-226-1580 Contact_Electronic_Mail_Address: kmarcoe@lcrep.org Hours_of_Service: 8:00 am to 5:00 p.m. PST.
