Forest Type Maps for New England from Historical Studies 1912-1956
This data package contains 3 GIS layers showing generalized forest types across New England as delineated in older forestry publications. These were digitized so that they can be used to illustrate broad vegetation patterns across the region in modern publications. These GIS layers include maps drawn by Hawley and Hawes (1912), RT Fisher (1933), and Westveld and the Committee on Silviculture, New England Section, Society of American Foresters (1956).
Historical Plat Maps of Dane County Digitized and Converted to GIS (1962-2005)
We constructed a time-series spatial dataset of parcel boundaries for the period 1962-2005, in roughly 4-year intervals, by digitizing historical plat maps for Dane County and combining them with the 2005 GIS digital parcel dataset. The resulting datasets enable the consistent tracking of subdivision and development for all parcels over a given time frame. The process involved 1) dissolving and merging the 2005 digital Dane County parcel dataset based on contiguity and name, 2) further merging 2005 parcels based on the hard copy 2005 Plat book, and then 3) the reverse chronological merging of parcels to reconstruct previous years, at 4-year intervals, based on historical plat books. Additional land use information such as 1) whether a structure was actually constructed (using the companion digitized aerial photo dataset), 2) cover crop, and 3) permeable surface area, can be added to these datasets at a later date.

Historical Local Climate Zones (LCZ) maps for Hong Kong (1845-2000)
<p>This dataset contains GIS maps of the historical urbanization of Hong Kong at 12 timeslices from 1845-2000 (1845, 1888, 1895, 1913, 1938, 1945, 1952, 1961, 1975, 1984, 1995, and 2000). These maps were compiled through classification of historical map material, photographs, paintings, and contemporary textual accounts. The maps describe the land cover of the historical urban core of the territory of Hong Kong: Victoria City on Hong Kong Island, and the Kowloon Peninsula on the mainland. Urban form is described in terms of the Local Climate Zones (LCZ) scheme presented by Stewart & Oke (2012).</p> <p>The dataset is currently in the format of a QGIS archive, but other file formats will be made available in the future and can be requested from the authors at any time.</p> <p>For further details on the process of generating the maps and their application, please see Yee and Kaplan (2022).</p> <p> </p> <p>Yee, M., & Kaplan, J.
