This web mapping application contains a vegetation type map (1:100,000) was prepared for the Tongass National Forest to provide up-to-date and more complete information about vegetative communities across the Ketchikan Misty Fjords Project Area. Approximately 4.6 million acres, 3.5 million acres of which are terrestrial lands including the area of inland waterbodies and rivers, were mapped through a partnership between the Geospatial Technology and Applications Center (GTAC), Tongass National Forest, and the Alaska Regional Office. The Tongass National Forest and their partners prepared the regional classification system, identified the desired map units (map classes) and provided general project management. GTAC provided project support and expertise in vegetation mapping. A combination of field and photo interpreted reference data was used to inform the models that output the final map products. Federal and GTAC personnel collected plot data on the ground.Vegetation type was assigned to modeling units (mapping polygons) using predictive classification models. The minimum map feature depicted on the map is 0.25 acres. All map products were designed according to the Forest Service mid-level vegetation mapping standards in order to be stored in the Forest GIS and National databases. This map product was generated using imagery primarily acquired in 2019 - 2022 and reference information was collected in the summers of 2019 - 2022. Therefore, the final map can be considered indicative of the existing vegetation conditions found within the project boundary in 2022.For more detailed information on mapping methodology please see the Ketchikan Misty Fjords Existing Vegetation Project Report.

This is the parcel dataset for the City of Ketchikan, City of Saxman and outlying areas within the Ketchikan Gateway Borough.

This service combines parcel data from various local government bodies in Alaska and describes a subset of input fields using consistent field names. This service was designed for use in statewide applications that only require specific types of land parcel information, and benefit from having this information in a single service with a consistent schema. Any changes to input parcel data will trigger this service to update. Note that many input services do not include a truly unique identifier, or sometimes any identifier at all. The 'parcel_id' field contains a record identifier carried over from the input service, or is null if there is none. The 'local_gov' value of any record can be used to reference an input parcel web service in the table below.During processing, a *mostly unique identifier is created, called 'feature_id'. Duplicate values will occur for records that have identical 'local_gov' and 'parcel_id' values and also identical geometries. These cases are extremely rare (< 0.003%), and for the vast majority of records 'feature_id' is unique. Any duplicate values will be attached to parcels in the exact same place.Please reference original parcel web services if your use case requires official, authoritative, or comprehensive land parcel information.

This stand density map (1:100,000) was prepared for the Tongass National Forest to provide up-to-date and more complete information about forest structure and patterns across the Ketchikan Misty Fjords Project Area. Over 3 million acres were mapped through a partnership between the Geospatial Technology and Applications Center (GTAC), Tongass National Forest, and the Alaska Regional Office. The Tongass National Forest and their partners prepared the regional classification system, identified the desired map units (map classes) and provided general project management.This layer was developed for areas classified as forest on the final vegetation type map layer. Stand density was assigned to modeling units (mapping polygons) using LiDAR data and predictive classification models. The minimum map feature depicted on the map is 0.25 acres. All map products were designed according to the Forest Service mid-level vegetation mapping standards in order to be stored in the Forest GIS and National databases. This map product was generated using imagery primarily acquired in 2019 - 2022 and LiDAR data acquired in 2018. Therefore, the final map can be considered indicative of the existing vegetation conditions found within the project boundary in 2022.Note that the forest structure metrics will be more reliable within the LiDAR extent versus outside. Outside the LiDAR extent these metrics were extrapolated using coarser spectral and topographic data. Therefore, it is important for a product user to understand whether they are within the LiDAR acquisition area as indicated by the "Source_Extent" field in the geodatabase to ascertain the ultimate reliability of a particular structure metric.For more detailed information on mapping methodology please see the Ketchikan Misty Fjords Existing Vegetation Project Report.

These data provide an accurate high-resolution shoreline compiled from imagery of Port of Ketchikan, AK . This vector shoreline data is based on an office interpretation of imagery that may be suitable as a geographic information system (GIS) data layer. This metadata describes information for both the line and point shapefiles. The NGS attribution scheme 'Coastal Cartographic Object Attribute Source Table (C-COAST)' was developed to conform the attribution of various sources of shoreline data into one attribution catalog. C-COAST is not a recognized standard, but was influenced by the International Hydrographic Organization's S-57 Object-Attribute standard so the data would be more accurately translated into S-57.

This web map contains reference data points with specific site information on vegetation dominance type and tree size for the Tongass National Forest, Ketchikan Misty Fjords Project Area to provide up-to-date and more complete information about vegetative communities, structure, and patterns across the project area.Reference data for this project came from numerous sources including: 1) Forest Service field crews collecting vegetation information specific to this project in 2019-2021 (582 total); 2) Young Growth Inventory data (1,444 total); 3) legacy data from previous Forest Service survey plots (556 total) and the Forest Inventory and Analysis (FIA) program; and 4) field data from Annette Islands supplied by the Bureau of Indian Affairs (94 total). These data posted here do not contain the FIA data nor the Bureau of Indian Affairs field data.Tongass National Forest personnel collected most of the ground data for this mapping effort using a variety of access means—such as, by helicopter, floatplane, boat, or by foot from existing trail and road infrastructure. The Young Growth Inventory information was leveraged for forests that are currently, or have been, actively managed in the past. The legacy, FIA, and Annette Islands data were all cross-referenced with the classification key to label each plot with a vegetation type class. Reference data was consolidated into a single database and reviewed within the context of their corresponding mapping segment using high-resolution imagery.For more detailed information on mapping methodology please see the Ketchikan Misty Fjords Existing Vegetation Project Report.
