Survey Control Web Map

The Muscatine County Survey Control Web Map displays coordinate information with related tie sheets for survey control monuments and tie sheets for the Public Land Survey System (PLSS) section corners recorded in the County.  This map was recently updated to include the Electronic County Section Corner Fieldbook, a compilation of PLSS section corners and property corners surveyed by the Engineering Department (since 2003) and Engineering Projects, a compilation of road and bridge project plans including fieldbooks, completed throughout the County.  They can be accessed by clicking on the green "Layer List" button at the bottom of the screen and selecting the layers that you would like to view.  This Web Map is jointly maintained by the Muscatine County Engineering Department and the Muscatine Area Geographic Information Consortium (MAGIC).

The Web map is intended to provide “one-stop shopping” for surveyors who perform property surveys in the County and must therefore submit their surveys digitally in accordance with Muscatine County’s Digital Submittal Ordinance.  The Web map is viewable by any desktop browser software and can also be viewed with any tablet or smartphone mobile device using either iOS or Android mobile operating systems.

Muscatine County’s survey control monuments were re-occupied in 2014 to update their coordinates to the National Geodetic Survey’s 2011 national adjustment of the NAD83 horizontal datum.  This datum adjustment is the same as that currently used by the Iowa Department of Transportation’s Real-Time Network (RTN).
