Extending Alaska Region National Hydrography Dataset Editing Protocols and Data Production to Accommodate Wetlands and other Value Added Attributes

The objectives of Phase 1 are to develop extended NHD data collection protocols to include: • Identifying suitable test areas within the Boreal (WRST) and Polar (NOAT) ecoregions of Alaska for applying NHD data collection protocols and testing update methods. At a minimum, these test locations must have complete coverage of Statewide Digital Mapping Initiative (SDMI) processed SPOT5 satellite imagery and SDMI IfSAR derived elevation data. • Developing a hybrid mapping process for delineation and classification of wetlands using a combination of software based tools for feature recognition and automated classification supported by traditional manual interpretation techniques. • Conducting a large area test of hydrography updates using extended feature mapping protocols within WRST. • Incorporation of resulting wetland features into both the AKHydro (i.e., the Alaska model for stewardship of hydrography data that complements NHD) and NHD data models as 2D area features. • Describing the US Geological Survey (USGS) NHD compliant development or edit workflow, starting with project identification, data checkout, data editing, conflation, NPS and USGS quality control (QC) processes, and final data check in to the USGS master database. • A description of the minimum data requirements to support NHD data development incorporating wetlands and other related hydrographic features. • A description of the project management process to data development, coordination,...
