Version 6 - Date: 06/30/2017


The City of Lincoln/Lancaster County has adopted geographic information system (GIS) technologies to store, manage and maintain geospatial –related data. The majority of the private engineering community utilizes computer aided design/drafting (CAD) tools for the creation of data such as subdivisions, water systems, storm drains, rights-of-way, pavement edges, etc. It is the goal of the City/County to expedite the review process by applying standards to the submittal of CAD and GIS data.

This document shall be considered the Standard for which contractors submitting data shall abide by. Data that does not adhere to these standards may be rejected by the City of Lincoln as inappropriate for use.

CAD\GIS Data Standards - Coordinate System

All geospatial data shall be submitted in the following Lancaster County Low-Distortion coordinate system, more defined as follows;

Transverse (UTM)
U.S. Survey Feet
Scale Factor:
Central Meridian:
-96 41 17
Projection Origin:
40 15 00
False Northing – meters:
False Easting – meters:
Vertical Datum:

CAD\GIS Data Standards - Format

Geospatial data shall be submitted in a format compatible with the City of Lincoln/Lancaster County’s GIS system. Acceptable formats are as follows;

  1. ESRI Geodatabases (file or personal)
  2. MicroStation .DGN (v8 and above)
  3. AutoCAD .DWG (Up to Version 2017)

CAD File Submittal - Accuracy

All references to accuracy of the subdivision plat shall refer to the Lincoln Municipal Code, Chapter 26.19 PDF, as well as the County Zoning Regulations PDF.

CAD File Submittal - Supplemental Information

Line work Details;

All line work shall be represented by single part line segments consisting of a starting point, and an ending point only. Multiple vertex polylines are not allowed.

Point Details;

Included within the associated dataset will include a point representing the True Point of Beginning for the associated boundary. Said point shall include a minimum of X and Y values located in Lancaster County Grid coordinates as Feet, or as Latitude\Longitude. Z values can be added as an option.

Annotation Details;

Each segment included in the submittal shall be dimensioned to the 1/100th of a foot (X.XX’), and shall be denoted as either a Platted Distance or a Measured Distance. This shall be defined as placing a (M) for ‘measured’, or a (P) ‘platted’ behind the corresponding distance.

For example - 131.49’(P) 131.58’(M) or 131.50 (M&P)

Note: All Curve Data shall consist of information regarding any curve on a property, boundary, or centerline. Curve data shall include all of the following;

  1. Radius
  2. Angle
  3. Tangent
  4. Length
  5. Chord Distance
  6. Chord Bearing

All points must be stored as a “POINT” feature, or a “Block Reference” or a “Cell” with the insert point of the feature being the centroid.
