Title: Springer Lab UAV Maize Phenotyping Project at UMN Saint Paul: 2018 and 2019 {Minnesota}
Contributors:- Raster data ; Table data ; Vector data ; Polygon data
- 2020
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.

Summary: This layer is a georeferenced raster image of the historic paper map entitled: A map of the New England states : Maine, New Hampshire, Vermont, Massachusetts, Rhode Island & Connecticut, with the adjacent parts of New York & lower Canada, compiled and published by Nathan Hale ; engraved by J.V.N. Throop. It was published by in 1826. Scale [ca. 1:506,880]. Covers also a portion of the state of New York and the province of Quebec, Canada. The image inside the map neatline is georeferenced to the surface of the earth and fit to the USA Contiguous Albers Equal Area Conic projection (Meters). All map collar and inset information is also available as part of the raster image, including any inset maps, profiles, statistical tables, directories, text, illustrations, or other information associated with the principal map. This map shows features such as roads, churches, drainage, state, county, and town boundaries, and more. Relief shown by hachures. Includes inset: Northern & eastern part of Maine and part of lower Canada and New Brunswick. Scale [ca. 1:1,267,200]. This layer is part of a selection of digitally scanned and georeferenced historic maps of New England from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.
