    Dataset provided by
    Lake County Illinois GIS
    Description

    This dataset has been deprecated. Please use our 2017 Countywide Contours instead.These data comprise of one foot contours showing the elevation of Lake County, IL corresponding to the orthometric heights of the bare surface of the county (no buildings or vegetation cover). These data were developed from LIDAR data obtained between April 16, 2007 and May 07, 2007, and further supplemented by break lines collected from aerial photography taken at the same time. The contours and the aerial photography meet National Map Accuracy Standards for a 1 inch = 100 foot product. The contours have been created to be cartographically pleasing, as such some generalization has been introduced as expected. The contours have been tested against the original LIDAR points and conforms to the American Society for Photogrammetry and Remote Sensing (ASPRS) Specifications and Standards Committee, 1990, ASPRS Accuracy Standards for Large-Scale Maps, CLASS 1 map accuracy. The vertical datum is the North American Vertical Datum of 1988. The U.S. Army Corps of Engineers Engineering and Design Manual for Photogrammetric Production recommends that data intended for this usage scale be used for any of the following purposes: route _location, preliminary alignment and design, preliminary project planning, hydraulic sections, rough earthwork estimates, or high-gradient terrain / low unit cost earthwork excavation estimates. The manual does not recommend that these data be used for final design, excavation and grading plans, earthwork computations for bid estimates or contract measurement and payment. Contour data is used by county agencies to study drainage issues such as flooding and erosion. Customers interested in the actual LiDAR data may download it at no cost from the USGS Center for LiDAR Information Coordination and Knowledge. These files are tiled by PLSS section and grouped by township and format for easier download. Please note that this dataset is available in for GIS in Esri shapefile format as well as for CAD in AutoCAD DWG and MicroStation DGN. We are unable to provide any support for CAD users beyond providing the data.

    Description

    This shapefile is a collection of lines converted from Autocad representing the symbols which indicate locations of Monarch Butterfly habitat as well as locations of various sensitive plant species, as part of the Environmentally Sensitive Habitat (ESH) Overlay officially adopted by the County Board of Supervisors. These symbols were taken from the ESH maps of the Goleta, Montecito, and Summerland Community Plans.Note that this layer was edited April 2, 2014 to add ESH plant symbols within the newly adopted Mission Canyon Community Plan, as well as to add the ESH-Steelhead Critical Habitat Stream that runs through the Mission Canyon Plan area.This shapefile does NOT depict the actual extent of any of these habitats or species, as these extents were not depicted on the ESH maps themselves either. However, in Montecito, the extent of the Monarch Butterfly Habitat was mapped as part of the ESH overlay itself. This extent is included in the polygon shapefile 'ESH_RC_ovrly.shp'

    Description

    This shapefile reflects linework from Annette Hoyt Flanders' drawn plans for the Cutting Garden. Features were traced in AutoCAD at the scale noted on the drawing and georeferenced to existing features. As such, it may serve as a record of the design intent for these spaces but should not be interpreted as a reliable survey of existing or historic features.

    Description

    Alaska Railroad centerline data compiled from a GPS survey by Mullikin Surveys in 2005. Data was delivered to MSB GIS by ARR as a series of AutoCAD dwg files that were merged into a single GDB format and then published as shapefile. MSB GIS added a couple of older abandoned centerlines in the Palmer area that are sometimes needed for maps.

The vertical datum is the North American Vertical Datum of 1988.

    The U.S. Army Corps of Engineers Engineering and Design Manual for Photogrammetric Production recommends that data intended for this usage scale be used for any of the following purposes: route location, preliminary alignment and design, preliminary project planning, hydraulic sections, rough earthwork estimates, or high-gradient terrain / low unit cost earthwork excavation estimates. The manual does not recommend that these data be used for final design, excavation and grading plans, earthwork computations for bid estimates or contract measurement and payment.

    Contour data is used by county agencies to study drainage issues such as flooding and erosion. Customers interested in the actual LiDAR data may download it at no cost from the USGS Center for LiDAR Information Coordination and Knowledge.

    These files are tiled by PLSS section and grouped by township and format for easier download. Please note that this dataset is available in for GIS in Esri shapefile format as well as for CAD in AutoCAD DWG and MicroStation DGN. We are unable to provide any support for CAD users beyond providing the data.

    Description

    This shapefile reflects linework from Annette Hoyt Flanders' drawn plans for the Cutting Garden. Features were traced in AutoCAD at the scale noted on the drawing and georeferenced to existing features. As such, it may serve as a record of the design intent for these spaces but should not be interpreted as a reliable survey of existing or historic features. Original drawing from Morven Stone House Archives.

    Description

    This shapefile reflects linework from Annette Hoyt Flanders' drawn plan for the Lower Terrace. Features were traced in AutoCAD at the scale noted on the drawing and georeferenced to existing features with some approximation. As such, it may serve as a record of the design intent for these spaces but should not be interpreted as a reliable survey of existing or historic features. In this case, we suspect that portions of this design were never built as drawn or were significantly revised. Original drawing from Morven Stone House Archives.

    Description

    This dataset has been deprecated. Please use our 2017 Countywide Contours instead.These data comprise of one foot contours showing the elevation of Lake County, IL corresponding to the orthometric heights of the bare surface of the county (no buildings or vegetation cover). These data were developed from LIDAR data obtained between April 16, 2007 and May 07, 2007, and further supplemented by break lines collected from aerial photography taken at the same time. The contours and the aerial photography meet National Map Accuracy Standards for a 1 inch = 100 foot product. The contours have been created to be cartographically pleasing, as such some generalization has been introduced as expected. The contours have been tested against the original LIDAR points and conforms to the American Society for Photogrammetry and Remote Sensing (ASPRS) Specifications and Standards Committee, 1990, ASPRS Accuracy Standards for Large-Scale Maps, CLASS 1 map accuracy. The vertical datum is the North American Vertical Datum of 1988.
