  1. Title: Supplementary data for "Trajectories of long duration balloons launched from McMurdo Station in Antarctica"

    Contributors:

    Summary: These files contain trajectory information for long-duration balloons launched from McMurdo Station in Antarctica. These balloons carry payloads addressing a wide range of scientific questions. We have analyzed these trajectories in order to estimate the expected range of trajectories to aid in mission planning for future balloon experiments from McMurdo. The data.csv.zip folder consists of 40 trajectory files for long-duration balloon flights launched from McMurdo Station in Antarctica, each containing latitude, longitude, altitude and time since launch. The files in analysis.csv.zip contain data products derived from analysis of the raw data.

  2. Title: Solar Insolation, Minnesota] (2006-2012)

    Contributors:

    Summary: The Minnesota Solar Suitability Analysis attempts to provide solar insolation analysis for the entire State of Minnesota. As far as we are aware, it is the only project of its scale in existence; similar studies have been limited to metro areas or focus on rooftop insolation. The project's existence is feasible because of statewide, freely available aerial lidar coverage. And the commitment of the team to work long hours on this unfunded project. The project finds itself at the intersection of renewable energy, big data analysis, geospatial technology, and open data availability. This data provides a measure of incedent solar radiation as it is intercepted by the earth surface, or features (such as vegetation and buildings) standing above the earth surface. The data is intended to be used to assess the suitability of a site for solar panel (photovoltaic cell) installations. The analysis used to produce this dataset looks at geographic location, surface slope, surface aspect, and the effects of shading based on local topography and adjacent structures. A digital surface model was generated from raw LiDAR data. Then, using this DSM, an individual locations on a grid surface were assessed for the amount of direct and indirect radiation that reaches the surface. This analysis was conducted at a 1m resolution for the entire state of Minnesota.

  3. Title: Digital Surface Model [Minnesota] (2006-2012)

    Contributors:

    Summary: A 1m resolution digital surface model that was generated from raw lidar data. This dataset was an intermediate product of a process to model potential solar insolation for the state of Minnesota. The Digital Surface Model (DSM) was created to represent the terrain and all object present on that terrain. This included buildings, tree cover, roads, and other natural and human-altered landscapes. In effect, the DSM is a three dimensional representation of Minnesota. It was generated using a Streaming Delauney Triangulation process through rapidlasso's LAStools software package. In this process, triangles are iteratively generated using nearby lidar returns and values for each point are determined by extracting interpolated elevation from the surface of the triangle. The result is a 1 meter resolution raster covering the state. Lidar is a form of active remote sensing technology that uses light pulses, most commonly in the near-infrared wavelengths, to collected surface elevation data. A laser scanner, mounted in an aircraft and combined with high-accuracy GPS, collects light returns that are interpolated into a point cloud. Each point represents one return from a laser pulse. The laser pulse has the ability to penetrate vegetation, multiple laser returns can be gathered for each pulse including the returns from below the vegetation.The accuracy of lidar returns allow for a unique, multi-faceted analytical dataset. The first point returns can be used to interpolate a topology of Minnesota that models the objects (i.e. building, trees, etc) and geography resting upon the terrain. The lidar point files for the state of Minnesota used in the study were collected between 2006 and 2012 through an intergovernmental initiative with the primary object of providing improved elevation data for flood mapping. In some regions, existing lidar data was acquired and transformed to new state standards. Areas where data did not exist or could not be transformed, were collected by contracted vendors. The composite data forms a seamless coverage of the state with a resolutions of at least 1.5 meters. Refer to metadata.html for full details.

  4. Title: Digitization of Minnesota and Wisconsin bathymetric maps resulting in hypsographic data

    Contributors:

    Summary: The data set includes hypsographic data (area-at-depth) for over 750 Minnesota and Wisconsin lakes throughout the states. The majority of these lakes (650+) did not have publicly available hypsography. The hypsography was derived by digitizing bathymetric DNR maps using ImageJ. One hundred Minnesota lakes were selected that had DNR hypsographic data (in the form of a DEM) available and a comparison between the hypsographic data derived from DEMs and ImageJ was completed. These results, as well as code and hypsographic data is all available. The purpose of this work was to release broad scale lake area-at-depth data for limnological and aquatic biology studies. Minnesota_Hypsography is a folder containing csv files of hypsographic data from Minnesota lakes. Validation_Hypsography is a folder containing csv files of hypsographic data used for validation. Wisconsin_Hypsography is a folder containing csv files of hypsographic data from Wisconsin lakes. MN_bathy.rds is an R file with interpolated depth for a subset of lakes in Minnesota. Hypso_QC.r is an R file used for quality control purposes with hypsographic data that has been digitzed. Validation_report is an R file that has the comparisons between DNR derived hypsography and ImageJ derived hypsography.

  5. Title: White-tailed deer density estimates across the eastern United States (2008)

    Contributors:

    Summary: In 2008, the Quality Deer Management Association (QDMA) developed a map of white-tailed deer density with information obtained from state wildlife agencies. The map contains information from 2001 to 2005, with noticeable changes since the development of the first deer density map made by QDMA in 2001. The University of Minnesota, Forest Ecosystem Health Lab and the US Department of Agriculture, Forest Service-Northern Research Station have digitized the deer density map to provide information on the status and trends of forest health across the eastern United States. The QDMA spatial map depicting deer density (deer per square mile) was digitized across the eastern United States. Estimates of deer density were: White = rare, absent, or urban area with unknown population, Green = less than 15 deer per square mile, Yellow = 15 to 30 deer per square mile, Orange = 30 to 40 deer per square mile, or Red = greater than 45 deer per square mile. These categories represent coarse deer density levels as identified in the QDMA report in 2009 and should not be used to represent current or future deer densities across the study region.

    Contributors:

    Summary: Imprint derived from the atlas in which this state of the map was first issued. From Camden's topographical and historical survey, Britannia, originally published with a set of county maps in the Latin edition of 1607. The principal sources of the maps of the 1607 edition were the maps of Saxton, Norden and Mercator, with the bulk of the engraving undertaken by William Kip (fl. 1598-1635) and William Hole (fl. 1600-1646). The first English edition (translated by Philamon Holland) was printed in 1610 with maps printed from the same plates. Two successive alterations were made to the plates before 1622 (including the addition of plate nos. to all but 14 of the maps), possibly in preparation for the second edition (not actually published until 1637, but entered at Stationers' Hall in 1625).
