Alexander, Walter E. Wall, Surveyor. Andrew B. Graham Co., Lithographers, Washington, D.C. (1906) (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced image of a map of Hawaii published in 1906. The map shows public lands; homestead settlement tracts; grazing, pineapple and sugar lands; forest reserves; forest lands not in reserves; wet lands (rice and taro); schools, post offices, etc. The original map appears in "Report of the Governor of the Territory of Hawaii to the Secretary of the Interior. 1906." The historic map layers in the Google Earth Rumsey Map Collection have been selected by David Rumsey from his large collection of historical maps, as well as some from other collections with which he collaborates. All the maps contain rich information about the past and represent a sampling of time periods, scales, and cartographic art, resulting in visual history stories that only old maps can tell. Each map has been georeferenced by Rumsey, thus creating unique digital map images that allow the old maps to appear in their correct places on the modern globe. Some of the maps fit perfectly in their modern spaces, while othersgenerally earlier period mapsreveal interesting geographical misconceptions of their time. Cultural features on the maps can be compared to the modern satellite views using the slider bars to adjust transparency. The result is an exploration of time as well as space, a marriage of historic cartographic masterpieces with innovative contemporary software tools.

  16. Title: Cover Types of the UMN Cloquet Forestry Center, 2021 {Cloquet, Minnesota}

    Contributors:

    Summary: Cover Types of the UMN Cloquet Forestry Center, 2021 is a polygon representation of forest stands and other vegetation types across the 3400-acre research forest. Polygon attributes represent the current status of forest inventory records for the CFC at the end of 2021 based on episodic updates to an original 2005 cover type mapping product. The University of Minnesota (UMN) Cloquet Forestry Center is a field research and instructional station associated with the College of Food, Agricultural, and Natural Resources Sciences (CFANS). The original dataset (shapefile) inventorying forest cover types at the University of Minnesota Cloquet Forestry Center was an outcome of a 2005 Covertype Mapping Project produced by Brian C. Loeffelholz and Guthrie Zimmerman on behalf of the UMN Department of Forest Resources (https://hdl.handle.net/11299/120191). The data provided here represents episodic updates to the 2005 covertype shapefile since that time. Forest stand boundaries, stand attributes, and attribute fields have been modified by Cloquet Forestry Center staff through 2021 to reflect spatial and temporal changes to cover types over time and from various management actions, predominately timber harvests.

  17. Title: Climate-biome envelope model for the Western Great Lakes Region

    Contributors:

    Summary: Research Highlights: We modeled climate-biome envelopes at high resolution in the Western Great Lakes Region for recent and future time-periods. The projected biome shifts, in conjunction with heterogeneous distribution of protected land, may create both great challenges for conservation of particular ecosystems and novel conservation opportunities. Background and Objectives: Climate change this century will affect the distribution and relative abundance of ecological communities against a mostly static background of protected land. We developed a climate-biome envelope model using a priori climate-vegetation relationships for the Western Great Lakes Region (Minnesota, Wisconsin and Michigan USA and adjacent Ontario, Canada) to predict potential biomes and ecotones—boreal forest, mixed forest, temperate forest, prairie–forest border, and prairie—for a recent climate normal period (1979–2013) and future conditions (2061–2080). Materials and Methods: We analyzed six scenarios, two representative concentration pathways (RCP)—4.5 and 8.5, and three global climate models to represent cool, average, and warm scenarios to predict climate-biome envelopes for 2061–2080. To assess implications of the changes for conservation, we analyzed the amount of land with climate suited for each of the biomes and ecotones both region-wide and within protected areas, under current and future conditions. Results: Recent biome boundaries were accurately represented by the climate-biome envelope model. The modeled future conditions show at least a 96% loss in areas suitable for the boreal and mixed forest from the region, but likely gains in areas suitable for temperate forest, prairie–forest border, and prairie. The analysis also showed that protected areas in the region will most likely lose most or all of the area, 18,692 km2, currently climatically suitable for boreal forest. This would represent an enormous conservation loss. However, conversely, the area climatically suitable for prairie and prairie–forest border within protected areas would increase up to 12.5 times the currently suitable 1775 km2. Conclusions: These results suggest that retaining boreal forest in potential refugia where it currently exists and facilitating transition of some forests to prairie, oak savanna, and temperate forest should both be conservation priorities in the northern part of the region. Data included here are the R code used to process the publicly available CHELSA data (see publications for citation) into the biome-climate envelope product (as .R files and .txt files) and the climate-biome envelope product itself (as .tif files).

  18. Title: Springer Lab UAV Maize Phenotyping Project at UMN Saint Paul: 2018 and 2019 {Minnesota}

    Contributors:

    Summary: This dataset provides a valuable resource for evaluating the utility of unmanned aerial vehicles to collect phenotypic data in agricultural fields. Many flights throughout the growing season of a maize experiment were conducted and this dataset includes digital elevation models generated from images within these flights, the plot boundary shapefiles for plot identification, plant height values extracted following Tirado et al., 2019 procedure, hand measurement height values conducted following flights, and yield data for each plot. This maize experiment consisted of twelve hybrids planted at three different planting densities (low, medium and high) and two planting dates (early and late) across two years and therefore provides a valuable resource for evaluating how temporal data collected from UAVs can aid in assessing plant productivity. It can also be utilized to develop and test different protocols for plant height extraction from DEMs at different growth stages as the hand measurements can be used to test the accuracy. Files include digital elevation models for all flights of our maize field in the summer of 2018 and 2019, the plot boundary shapefiles, information on each plot including planting date and density and stand counts, yield data for all plots, and weather station data for both summers. More detailed info can be found in the readme file.

  19. Title: Distribution Maps and Models for 13 Invasive Plants in Minnesota

    Contributors:

    Summary: This dataset consists of raster (.tif) and map (.png) files for 13 invasive plants in Minnesota. Species included consist of: common buckthorn, glossy buckthorn, multiflora rose, garlic mustard, Canada thistle, common tansy, leafy spurge, spotted knapweed, wild parsnip, purple loosestrife, Japanese knotweed, narrowleaf bittercress, and plumeless thistle. The rasters (.tif files) included here consist of the output of species distribution modeling (SDM) conducted for each species; these files depict the mean cross-model and cross-assumption distribution estimates for each species, on a scale of 0 to 1. Values near 0 indicate low likelihood of finding the species there, or low habitat suitability, and values near 1 represent a high likelihood of finding the species. The maps (.png files) included here depict the same information, but in a static non-GIS compatible format.

  20. Title: (Composite Map) (Facsimile) Rocque's Map of London. 1746 (Raster Image)

    Contributors:

    Summary: This raster layer is a georeferenced image of a map titled "Composite Map: (Facsimile) Rocque's Map of London. 1746." Published in 1919, this composite map is considered one of the best facsimiles of the original Rocque Map ("A plan of the cities of London and Westminster, and borough of Southwark"), created by John Rocque and first published in 1746. A scanned version of this map available from The David Rumsey Map Collection was georeferenced by the Kindred London mapping project. The broad goal of the Kindred London project is to create four digitized road networks from four historic maps of London that will be used for an online, interactive web platform that will allow users to experience what it would have been like to travel the streets of London.
