Minnesota Elevation Mapping Project (LiDAR)
This project will create a high accuracy elevation dataset - critical for effectively planning and implementing water quality projects - for the state of Minnesota using LiDAR (Light Detection and Ranging) and geospatial mapping technologies. Although some areas of the state have been mapped previously, many counties remain unmapped or have insufficient or inadequate data. This multi-year project, to be completed in 2012, is a collaborative effort of Minnesota's Digital Elevation Committee and partners with county surveyors to ensure accuracy with ground-truthing. The first year (FY 2010) focuses on Southwest Minnesota. The arrowhead, Twin Cities metro, and central lakes regions will be completed in 2011 and 2012.
Accurate topographic information will greatly enhance the ability of decision makers and resource managers to understand how water interacts with the landscape and will provide the foundation for developing innovative, effective, and defendable resource management strategies. Completion of a statewide elevation dataset will reduce cost and increase effectiveness of clean water projects. The data have myriad additional uses; for example, collecting elevation data over the life of a mining project will allow the state to more accurately document mineral extraction, potentially increasing royalty income from mineral leases.
$1350000 the first year and $1350000 the second year are to acquire and distribute high-resolution digital elevation data using light detection and ranging to aid with impaired waters modeling and TMDL implementation under Minnesota Statutes chapter 114D. The money shall be used to collect data for areas of the state that have not acquired such data prior to January 1 2007 or to complete acquisition and distribution of the data for those areas of the state that have not previously received state funds for acquiring and distributing the data. The distribution of data acquired under this paragraph must be conducted under the auspices of the Minnesota Geospatial Information Office which shall receive up to 2.5 percent of the appropriation in this paragraph to support coordination of data acquisition and distribution. Mapping and data set distribution under this paragraph must be completed within three years of funds availability. The commissioner shall utilize department staff whenever possible. The commissioner may contract for services only if the services cannot otherwise be provided by the department.
In FY14 the DNR will publish and promote MnTOPO a web-based application that will provide access to LiDAR data to a wide audience including the general public and water management professionals. MnTOPO has data viewing and printing capabilities as well as data access and download. Data access and download volumes will be readily available as measures of the value of this information.
The DNR will develop and publish an Elevation Data Governance Plan and coordinate elevation data standards maintenance and development of products based on LiDAR data. This will ensure long term management of elevation data and the MnTOPO portal. It will also ensure that the needs of the water management officials who rely on this data to formulate their management strategies are met.
MnTOPO a web site built to make the LiDAR data collected as part of this project easily accessible was completed on time and under budget. Upon its release MnTOPO proved to be an instant success with users viewing and downloading elevation data for a wide variety of water resource management purposes. The two foot contours have been the most popular product of the MnTOPO web application. The total volume of data users downloaded using MnTOPO in its first six months of operation is more than that of the total collection. Due to changes in staff’s managerial responsibilities associated with Minnesota’s LiDAR data an Elevation Data Governance Plan was not completed. The DNR did coordinate the development of elevation data standards with the MN LiDAR Research and Education Committee as these two interests work collaboratively to guide long-term management of Minnesota’s elevation data and the MnTOPO application.

In FY13 DNR will complete publishing and distribution of 21 326 square miles of data from the Arrowhead and Metro project areas plus Blue Earth County. Data for the Red River basin (19 counties covering 22 700 square miles) will be reformatted published and distributed.
DNR will acquire publish and distribute new LiDAR data over 3 078 square miles in St. Louis and Carlton Counties to update data following a major flood event that resulted in landscape changes making current data invalid.
DNR will also develop a web-based map application that presents elevation data that can be viewed on standard computers or mobile devices (without the need for Geographic Information System software).
In FY13 DNR achieved complete coverage of high accuracy elevation for the state of Minnesota. DNR completed the acquisition quality assurance publication and distribution of LiDAR data and associated products for the Arrowhead region Metro region Central Lakes region Blue Earth County and the Duluth area update. Data for counties in the Red River Basin were reformatted to meet state standards incorporated into data holdings. In total more than 52 000 square miles of data was made published and made available to be used for a variety of clean water projects.
Significant progress was made on the design and application development for the LiDAR Web Viewer during FY13; however the application was deemed by the project team to be not ready for general release.
