The maps are prepared from the analysis of <br />high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A <br />margin of error is inherent in the use of imagery; thus, detailed on -the -ground inspection of any particular <br />site may result in revision of the wetland 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 <br />analysts, the amount and quality of the collateral data and the amount of ground truth verification work <br />conducted. Metadata should be consulted to determine the date of the source imagery used and any <br />mapping problems. <br />Wetlands or other mapped features may have changed since the date of the imagery or field work. There <br />may be occasional differences in polygon boundaries or classifications between the information depicted on <br />the map and the actual conditions on site. <br />Data exclusions <br />Certain wetland habitats are excluded from the National mapping program because of the limitations of <br />aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or <br />submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore <br />coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded <br />from the inventory. These 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 <br />wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or <br />products of this inventory, to define the limits of proprietary jurisdiction of any Federal, state, or local <br />government or to establish the geographical scope of the regulatory programs of government agencies. <br />Persons intending to engage in activities involving modifications within or adjacent to wetland areas should <br />seek the advice of appropriate federal, state, or local agencies concerning specified agency regulatory <br />programs and proprietary jurisdictions that may affect such activities. <br />9 of 9 8/29/2018, 9:48 AM <br />
