What does this data set describe?
The Ambient Water Quality Monitoring Network is managed by the Illinois Environmental Protection Agency. This data set shows locations of all fixed monitoring sites in the Fox Watershed. This data is a sub-set of a state-wide data set. Data set was generated from location data created by the IEPA (in latitude/longitude, decimal degree format).
-
How should this data set be cited?
Data set developed by Illinois EPA and GIS data set created by Chris Jennings, Illinois State Water Survey, 5/21/03, fox-AWQMNsites.
-
What geographic area does the data set cover?
Bounding coordinates:West: -88.825005East: -88.178337North: 42.484366South: 41.350442
-
What does it look like?
-
Does the data set describe conditions during a particular time period?
Calendar date: REQUIRED: The year (and optionally month, or month and day) for which the data set corresponds to the ground.Currentness reference:REQUIRED: The basis on which the time period of content information is determined.
-
What is the general form of this data set?
Geospatial data presentation form: vector digital data
-
How does the data set represent geographic features?
-
How are geographic features stored in the data set?
This is a Vector data set. It contains the following vector data types (SDTS terminology):- Entity point (11)
-
What coordinate system is used to represent geographic features?
The map projection used is Lambert Conformal Conic.
Projection parameters:Standard parallel: 33.000000Standard parallel: 45.000000Longitude of central meridian: -89.500000Latitude of projection origin: 33.000000False easting: 2999994.000000False northing: 0.000000
Planar coordinates are encoded using coordinate pair.Abscissae (x-coordinates) are specified to the nearest 0.001024.Ordinates (y-coordinates) are specified to the nearest 0.001024.Planar coordinates are specified in survey feet.
The horizontal datum used is D_Clarke_1866.The ellipsoid used is Clarke 1866.The semi-major axis of the ellipsoid used is 6378206.400000.The flattening of the ellipsoid used is 1/294.978698.
