U.S. National Grid Location Mobile Marking System
As described in detail at the MnGeo U.S. National Grid Location Marker Proposal website, an effort is underway to develop a standardized method for marking locations with U.S. National Grid (USNG) coordinates. In tandem with this marker concept, through a grant provided by the University of Minnesota, Center for Transportation Studies, Local Operational Research Assistance (OPERA) Program, SharedGeo personnel have developed a mobile printing system that will produce these USNG markers at the point of install. As a trial of these nationally ground breaking concepts, SharedGeo is currently working with the Northern Minnesota emergency response community toward installation of these USNG markers along a section of a major recreational trail during Spring 2011.
With regard to components of the mobile printing system, this developmental effort uses integration of off-the-shelf Linux based phone handsets, blue tooth networked portable printing equipment and custom programming and configuration of open source software. The system allows the user to print a USNG marker in the field using the phone based GPS. The phone also incorporates a mapping visualization user interface.
An additional outcome of this effort has been development of a USNG Quick Response (QR) code marker capability. This type of output produces a marker in the form of a 2D matrix barcode that contains USNG location information; effectively creating a high-tech location message can be read by almost all camera ready cell phones. The potential applications of this technology for disaster response and combat scenarios are thought to be significant. Technical details of this effort are available at the project’s OPERA website. A poster that shows the inter-relationships of these components, as well as developments related to low cost Automatic Vehicle Location (AVL) capability is also available. Click here to download.
