You may request a list of species known or likely to occur near some location that you can identify as coordinates such as available from a Global Positioning Satellite receiver. If you know part of a name that can be found published on a U.S.G.S topographic map, then you may want to use Geographic Search By Place Name. If you do not have a coordinate or name then may want to use Geographic Search By Map.
A species list resulting from a Geographic Search is based on references for distribution of species in Virginia by City and County, by United States Geologic Survey 7.5 minute quadrangle, by United States Geologic Survey Hydrologic Unit (watersheds), and by United States Department of Agriculture Natural Resources Conservation Service Hydrologic Unit (watersheds). The point of interest and search radius you provide determine which will be used.
|* Example coordinate formats all representing the same point:|
Latitude and longitude
Note: both negative and
are West hemisphere.
|37,05,09 77,38,11||Degrees, Minutes, and Seconds|
|37,05,09 -77,38,11||Degrees, Minutes, and Seconds|
|370509 773811||Degrees, Minutes, and Seconds|
|37,05.1500 77,38.1833||Degrees, Decimal Minutes|
|37.085833 77.636333||Decimal Degrees|
UTM East, North, Zone
|265661 4107443 18||meters zone 18|
|799004 4109487 17||meters zone 17|
|799004 4109487||meters (default zone 17)|
Note: a "complete" coordinate is made up of all parts needed to identify a point on a map. Latitude may be one decimal value or contain parts for degree, minute, and second. When Latitude is made up of parts then the parts need to be combined by comma (,) and presented using no spaces. Longitude is presented in the same manner as Latitude. When Latitude is provided then Longitude follows after a space on the same line. When UTM East is provided then UTM North and optionally Zone follow on the same line separated by space. A Tab character may be used in place of a space character.
Because typical VaFWIS reports represent landscape searches over thousands of meters, while using VaFWIS the DGIF staff are not concerned about UTM coordinate precision within plus or minus 10 meters.
Coordinates are represented as Latitude / Longitude within VaFWIS program modules. When a client chooses to display coordinates as UTM (Universal Transverse Mercator), values entered by the client will be converted to Latitude / Longitude within a precision of about 1 meter. Internal Latitude / Longitude values may be converted back to UTM for display with a precision of about 1 meter. Coordinate values may change slightly with each conversion. Converting UTM to Latitude / Longitude, and then converting that result back to UTM will likely result in a value within 2 meters of the original. The accumulated change in value is called "Coordiante Creep".
