MnCon is a coordinate conversion program that performs conversions within or across the North American Datums of 1927 and 1983.  It works on keyboard input or ASCII (text) files of specific formats.  It converts between any two of 232 different map projections including: NAD27 and NAD83 latitude/longitude, NAD27 and NAD83 universal transverse mercator zone 15 extended, the three Minnesota state plane zones in both NAD27 and NAD83, 68 NAD83 Minnesota county coordinate system zones (including one covering all of St Louis County) and 159 NAD27 project zones.  Essentially MnCon replaces CONAD27, CONAD83 and the National Geodetic Survey's NADCON. Other individuals or agencies may use the MnCon at their own risk, with no expectation of user support.

MnCogo32 is a coordinate geometry program developed by the Minnesota Department of Transportation for making survey calculations in field and office settings for horizontal and vertical curves, grading widths, and proportions.  It also calculates Public Land Survey section breakdowns.

It accepts four input file types: Comma-delimited, GEOPAK Print Points, GEOPAK XY, and SDMS.

The Section Subdivision function will write an input file that can be read by Bentley GEOPAK Cogo. PlotPLS.mvba is a Bentley MicroStation V8 macro written by MnDOT that can also use the same input file. A copy of that macro will be placed in the local MnCogo32 installation directory by the installer (Macro version 1.0.3, 10/7/2015).  Other individuals or agencies may use MnCogo32 at their own risk, with no expectation of user support.
