8/2/2021 INC:Explore Location resources <br /> The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information <br /> on the location,type and size of these resources.The maps are prepared from the analysis of high altitude imagery. <br /> Wetlands are identified based on vegetation,visible hydrology and geography.A margin of error is inherent in the use <br /> of imagery;thus, detailed on-the-ground inspection of any particular site may result in revision of the wetland <br /> boundaries or classification established through image analysis. <br /> The accuracy of image interpretation depends on the quality of the imagery,the experience of the image analysts,the <br /> amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata <br /> should be consulted to determine the date of the source imagery used and any mapping problems. <br /> Wetlands or other mapped features may have changed since the date of the imagery or field work.There may be <br /> occasional differences in polygon boundaries or classifications between the information depicted on the map and the <br /> actual conditions on site. <br /> Data exclusions <br /> Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial <br /> imagery as the primary data source used to detect wetlands.These habitats include seagrasses or submerged aquatic <br /> vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some <br /> deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory.These <br /> habitats, because of their depth, go undetected by aerial imagery. <br /> Data precautions <br /> Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a <br /> different manner than that used in this inventory.There is no attempt, in either the design or products of this <br /> inventory,to define the limits of proprietary jurisdiction of any Federal, state, or local government or to establish the <br /> geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities <br /> involving modifications within or adjacent to wetland areas should seek the advice of appropriate federal, state, or <br /> local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such <br /> activities. <br /> 0 <br /> \%N <br /> https://ecos.fws.gov/ipac/location/WJEITLSHWNBTHOBGB6QIENDANI/resources 12/12 <br />
