ControlFinder Notes

Below is a timeline of updates and additions we've made to ControlFinder since version 2.0 went live in April, 2011.  We add and update data continually, and use this page to provide users with timely information pertaining to enhancements or issues related to the application.

WI-NGS Datasheets Available

October 09, 2013

WI NGS datasheets are available for download as a zipped 15MB text file. The unzipped file is 72MB and users should avoid using Notepad to view this file since it doesn't format them correctly. To search for a datasheet's PID, use the keyboard keys Ctrl F.

These datasheets are current as of September 4, 2013 and are also available from our office. Contact This e-mail address is being protected from spambots. You need JavaScript enabled to view it at 608/263-4371.

GPX Export Option Now Available

July 17, 2012

In an effort to continue to meet the needs of the surveying user community, the State Cartographer’s Office recently expanded the menu of export options available from our application with the addition of the GPX format.

Essentially, GPX (the GPS eXchange Format) is a light-weight XML data format used for the vast majority of GPS data sharing (i.e., waypoints, routes, and tracks) between applications and Web services on the Internet.

In addition to the recent addition of GPX to the export options menu, ControlFinder includes Shapefile, GPX file, KML file, SDMS CTL file, NGS Data Sheets, and Text file formats.

Version 2.0 Released

April 20, 2010

The State Cartographer's Office recently launched the new version (Version 2.0) of its popular ControlFinder application, providing users with new functions and enhanced cartography. The new ControlFinder application is built on open source software, including the GeoMoose web application framework, the OpenLayers Javascript Library, JQuery Javascript functions, the MapServer mapping engine, and a PostGIS/Postgresql database system for storing spatial data. The new app also makes use of the Google Maps API for base map display. With this new software configuration, we are able to make use of modern software tools and methods that will provide the flexibility needed to add or modify functions and features over time.
