Geospatial Data Requirements

Computer Aided Design and Drafting (CADD) Drawings

  1. All delivered CADD data must be provided in AutoCAD® 2015 or exchange format convertible to AutoCAD® 2015.
  2. CADD drawings should follow The American Institute of Architects (AIA) layer naming conventions.
  3. CADD drawings must be delivered in a local coordinate system such as State Plane, datum NAD 83, or the appropriate County Coordinate System (see Wisconsin Coordinate Reference Systems, Second Edition).
  4. Each feature type, such as control points, property pins, contours, individual utilities, existing structures, text labels, etc. must be on a separate layer in CADD. Some examples are:
  • Unpaved parking in one layer and paved parking in another.
  • Utility poles in one layer and electrical lines in another layer.
  • Contour lines in one layer, and elevation text in another layer.
  • Property boundaries and property corners in separate layers.
  • Each survey point attribute in a separate layer. The data ID number, elevation, and description should all be in a separate layer.

Geographical Information Systems (GIS)

  1. All delivered datasets must be provided in an ESRI file geodatabase ArcGIS® 10.1 or 10.2. Map documents should be in ArcGIS® 10.1 or 10.2 and have ‘relative path’ mode turned on.
  2. All delivered datasets must be Federal Geographic Data Committee (FGDC) metadata compliant. Metadata contact information for most cases will be:

    Paul Boehnlein, GIS Specialist
    University of Wisconsin System Administration
    780 Regent Street – Suite 239
    Madison, WI 53715
    pboehnlein@uwsa.edu
    (608) 263-4410

  3. All delivered GIS datasets must be delivered in a local coordinate system such as State Plane, datum NAD 83, or the appropriate County Coordinate System (see Wisconsin Coordinate Reference Systems, Second Edition).
  4. All delivered GIS data must have proper topology and be ready to use in a GIS environment. Basic topology rules should be applied when converting data from CADD or creating features in a GIS environment. For example, unnecessary vertices should be eliminated, line nodes should snap to other applicable node and point features, polygon features should not have gaps or overlaps, and any unwanted artifacts should be deleted.

Survey Requirements

  1. The survey shall be conducted by a licensed surveyor and shall be documented on a 1″ = 40′-0′ minimum scale drawing that includes the following:
    1. Legal description of the property tied to a recognized and recorded landmark.
    2. Property lines, including interior angles (at changes of course), bearings, and distances. Include all known easements, right-of-ways, restrictions, obstructions or impediments.
    3. Area in acres of each parcel of land.
    4. True and magnetic north arrow.
    5. Name of engineer or surveyor, date survey was conducted, surveyor’s certification (signed and sealed), and name of project.
  2. All transit points shall be monument with a 1″ diameter x 24″ long iron pipe or a ¾” diameter x 24″ long iron rod.

Certified Survey Map (CSM) Deliverables to Project Manager

  1. Completed applications for submittal to the designated County and Municipality.
  2. Stamped hard copy CSM drawing on bond containing requirements in Survey Requirements A (above).
  3. Digital copy of CSM in Adobe PDF with surveyor’s stamp.
  4. Digital copy of survey in AutoCAD® 2015, or exchange format convertible to AutoCAD® 2015. CADD drawings should follow The American Institute of Architects (AIA) layer naming conventions and be tied to a local coordinate system such as State Plane or the appropriate County Coordinate System (see Wisconsin Coordinate Reference Systems, Second Edition).

Property Boundary Deliverables to Owner

  1. Stamped hard copy drawing on bond containing requirements in Survey Requirements A (above).
  2. Digital copy of survey in Adobe PDF with surveyor’s stamp.
  3. Digital copy of survey in AutoCAD® 2015, or exchange format convertible to AutoCAD® 2015. CADD drawings should follow The American Institute of Architects (AIA) layer naming conventions and be tied to a local coordinate system such as State Plane or the appropriate County Coordinate System (see Wisconsin Coordinate Reference Systems, Second Edition).
