Summary: This layer is a georeferenced raster image of the historic paper map entitled: Railroad map of New England & eastern New York : compiled from the most authentic sources, by J.H. Goldthwait. It was published in 1849 by Redding & Co. and Clark, Austin, & Co. Scale [ca. 1:700,000]. Covers Massachusetts, Rhode Island, Connecticut, and portions of New York, Vermont, New Hampshire, and Maine. 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 railroads completed and in progress, drainage, state, county, and town boundaries, and more. Includes inset: Boston & vicinity showing the Grand Junction R.R. Scale [ca. 1:170,000]. This layer is part of a selection of digitally scanned and georeferenced historic maps of New England from the Harvard Map Collection.

Title: Climate-biome envelope model for the Western Great Lakes Region
Contributors:- Vector data ; Raster data
- 2021
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).

Summary: This layer is a georeferenced raster image of the historic paper manuscript map: Battery Wagner, Morris Isld., Francis D. Lee, Capt. Engrs. ; Langdon Cheves, Asst. Engr. in charge of work ; drawn by F.W. Bornemann, C.S. Engr. Office. It was drawn Nov 26, 1863. Scale [1:480]. The image inside the map neatline is georeferenced to the surface of the earth and fit to the South Carolina State Plane Coordinate System (in Meters) (Fipszone 3900). 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 Fort dimensions and structures, landscape of area surrounding Fort, drainage, and more. This layer is part of a selection of digitally scanned and georeferenced historic maps of the Civil War from the Harvard Map Collection. Many items from this selection are from a collection of maps deposited by the Military Order of the Loyal Legion of the United States Commandery of the State of Massachusetts (MOLLUS) in the Harvard Map Collection in 1938. These maps typically portray both natural and manmade features, in particular showing places of military importance. The selection represents a range of regions, originators, ground condition dates, scales, and purposes.
