Lot lines delineate the boundary of a lot or lots within a tax parcel. Most lot lines were digitized from record information using bearing and distance (recorded subdivision plats and recorded deeds). Some were scanned from recorded plat mylars. Lot polygons delineate the boundary of a lot or lots within a tax parcel. Currently, these exist only for the City of Seward.

The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk Information And supporting data used to develop the risk data. The primary risk; classificatons used are the 1-percent-annual-chance flood event, the 0.2-percent- annual-chance flood event, and areas of minimal flood risk. The DFIRM Database is derived from Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA). The file is georeferenced to earth's surface using the UTM projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:12,000.

This application was created to support the Mapping Existing Vegetation on Kenai Peninsula story map.Dominance type, canopy cover, and tree size maps were developed for the the Kenai Peninsula, including the Chugach National Forest, Kenai Wildlife Refuge, and Alaska Fish and Game. Over 5.7 million acres (including other federal, state, native, and private land inholdings) were mapped through a partnership between the Geospatial Technology and Applications Center (GTAC), Chugach National Forest, Alaska Regional Office, State of Alaska, Kenai National Wildlife Refuge, Kenai Burough, and National Park Service. The Chugach 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 ground and helicopter reference data was used to inform the classification models that output the final maps. Federal and State field personnel collected plot data on the ground, while Ducks Unlimited and GTAC personnel collected the helicopter data.Classification models were used to characterize modeling units (mapping polygons) with the following vegetation attributes: 1) dominance type; 2) tree canopy cover; 3) tree size; and 4) tall shrub canopy cover. 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 2016 and 2017. The field data used as reference information for this mapping project was collected in the summer of 2017. Therefore, the final map can be considered indicative of the existing vegetation conditions found on the Kenai Peninsula in 2017.

PDF Map of FCC Form 477 provider reported maximum download speeds by census block for January - June 2020. This map seeks to highlight areas that are undeserved by terrestrial broadband (fiber/cable/dsl on the ground), with "underserved" defined as down/up speeds less than 25/3 Mbps.These data represent a static snapshot of provider reported coverage between January 2020 and June 2020. Maps also depict the locations of federally recognized tribes, Alaskan communities, ANCSA and borough boundaries.Broadband coverage is represented using provider reported speeds under the FCC Form 477 the amalgamated broadband speed measurement category based on Form 477 "All Terrestrial Broadband" as a proxy for coverage. This field is unique to the NBAM platform. These maps do not include satellite internet coverage (and may not include microwave coverage through the TERRA network for all connected areas).This map was produced by DCRA using data provided by NTIA through the NBAM platform as part of a joint data sharing agreement undertaken in the year 2021. Maps were produced using the feature layer "NBAM Data by Census Geography v4": https://maps.ntia.gov/arcgis/home/item.html?id=8068e420210542ba8d2b02c1c971fb20Coverage is symbolized using the following legend:No data avalible or no terrestrial coverage: Grey or transparent< 10 Mbps Maximum Reported Download: Red10-25 Mbps Maximum Reported Download: Orange25-50 Mbps Maximum Reported Download: Yellow50-100 Mbps Maximum Reported Download: Light Blue100-1000 Mbps Maximum Reported Download: Dark Blue_Description from layer "NBAM Data by Census Geography v4":This layer is a composite of seven sublayers with adjacent scale ranges: States, Counties, Census Tracts, Census Block Groups, Census Blocks, 100m Hexbins and 500m Hexbins.

FEMA Framework Basemap datasets comprise six of the seven FGDC themes of geospatial data that are used by most GIS applications (Note: the seventh framework theme, orthographic imagery, is packaged in a separate NFIP Metadata Profile): cadastral, geodetic control, governmental unit, transportation, general structures, hydrography (water areas & lines. These data include an encoding of the geographic extent of the features and a minimal number of attributes needed to identify and describe the features. (Source: Circular A16, p. 13)

Terrain-related imagery are primarily derived from Lidar, stereoscopic aerial imagery, or Interferometric Synthetic Aperture Radar datasets. Consequently, these derivatives inherit the limitations and uncertainties of the parent sensor and platform and the processing techniques used to produce the imagery. The terrain images are orthographic; they have been georeferenced and displacement due to sensor orientation and topography have been removed, producing data that combines the characteristics of an image with the geometric qualities of a map. The orthographic images show ground features such as roads, buildings, and streams in their proper positions, without the distortion characteristic of unrectified aerial or satellite imagery. Digital orthoimages produced and used within the Forest Service are developed from imagery acquired through various national and regional image acquisition programs. The resulting orthoimages can be directly applied in remote sensing, GIS and mapping applications. They serve a variety of purposes, from interim maps to references for earth science investigations and analysis. Because of the orthographic property, an orthoimage can be used like a map for measurement of distances, angles, and areas with scale being constant everywhere. Also, they can be used as map layers in GIS or other computer-based manipulation, overlaying, and analysis. An orthoimage differs from a map in a manner of depiction of detail; on a map only selected detail is shown by conventional symbols, whereas on an orthoimage all details appear just as in original aerial or satellite imagery.This record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

KPB Redacted Parcels depicts the boundaries of tax parcels within the Kenai Peninsula Borough. The tax parcel information has been combined with assessing and tax information from CAMA and tax systems. Some ownership information has been removed at the request of the landowners.

The Kenai Peninsula Borough utilizes a uniform street addressing system, as described within Kenai Peninsula Borough Code of Ordinances Chapter 14.20. The Borough assigns physical addresses within borough boundaries, except for within the cities of Kenai, Soldotna, Seward and Homer (these cities utilize their own systems but provide the data to the Borough). Physical address locations are used by Borough Public Service Answering Points (dispatch centers) and emergency response personnel.

Physical address locations may be placed in the centroid of a tax parcel, or top of building; locations are dependent upon the best information available at the time of assignment.

This report provides details for the Kenai Peninsula Project Area of the Alaska Region Existing Vegetation Mapping Effort. An existing vegetation map was prepared in a collaborative effort between the Forest Service and multiple agency partners. This map was designed to be consistent with the standards established in the Existing Vegetation Classification and Technical Guide (Nelson et al. 2015), and to provide baseline information to support project planning and inform land management of the Kenai Peninsula. The final map comprises four distinct, integrated feature layers: 1) dominance type; 2) tree canopy cover; 3) tree size; and 4) tall shrub canopy cover. The dominance type map consists of 33 classes, including 28 vegetation classes and 5 other land cover types. Continuous canopy cover products were developed for areas classified as forest and tall shrub. Additionally, a thematic layer depicting tree diameter class categories was generated for areas classified as forest. Geospatial data, including remotely sensed imagery, topographic data, and climate information, were assembled to classify vegetation and produce the map. A semi-automated image segmentation process was used to develop the modeling units (mapping polygons), which delineate homogeneous areas of land cover. Land cover class determinations were made for field sites, collected on the ground or from above in a helicopter, in order to characterize associated mapping polygons. Subsequently, this reference data was used to develop the predictive random forest models that ultimately produced the final map products. Important model drivers included Sentinel 2 and Landsat 8 satellite imagery for dominance type prediction, while vegetation structure models relied heavily on Light Detection and Ranging (LiDAR) and Interferometric Synthetic Aperture Radar (IfSAR) data sources. The mapping process utilized various Forest Service Enterprise software, adopting the most contemporary methods and technology. Most of the reference information and geospatial data were collected in the summer of 2017, and therefore, the final map can be considered indicative of the existing vegetation conditions found on the Kenai Peninsula at that time. Once the final map was produced, an accuracy assessment was conducted to reveal individual class confusion and provide additional insight into the reliability of the final map for resource applications.

Vegetation information collected via air survey in 2017 over the Chugach National Forest and the Kenai Peninsula. Data collected includes vegetation group, dominance type,community type, community sub-type and plant community along with description notes and photos. Data was gathered using ArcGIS Collector application.
