  8. Title: The 1st Hampshire representative district within the Pioneer Valley, Massachusetts, 1996 (Raster Image)

    Contributors:

    Summary: This layer is a georeferenced raster image of the historic paper map entitled: The 1st Hampshire representative district within the Pioneer Valley : produced by Pioneer Valley Planning Commission. It was published by Pioneer Valley Planning Commission in 1996. Scale ca. 1:210,000. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Massachusetts State Plane Coordinate System, Mainland Zone (in Feet) (Fipszone 2001). 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, index maps, legends, or other information associated with the principal map. This map shows features such as roads, railroads, drainage, cities and other human settlements, territorial boundaries, shoreline features, and more. Includes also developed land, outdoor recreation/open space, and open water. This layer is part of a selection of digitally scanned and georeferenced historic maps from the Harvard Map Collection. These maps typically portray both natural and manmade features. The selection represents a range of originators, ground condition dates, scales, and map purposes.

  12. Title: Digital Aerial Imagery: Ozaukee County, WI 2020

    Contributors:

    Summary: The Southeastern Wisconsin Regional Planning Commission (SEWRPC) obtained digital, 4-band orthoimagery services in 2020 in conjunction with Wisconsin Regional Orthoimagery Consortium (WROC) in 2020 (by Ayres Associates) for Ozaukee, Racine, Walworth, Washington, and Waukesha counties. The aerial imagery was collected on: 4/5, 4/7, 4/11, 4/16, 4/18, 4/19, 4/20, and 4/21 using an UltraCam Eagle M2 and M3 mounted in a fixed-wing aircraft. Aerial imagery was collected to support 0.25 foot ground sample distance (GSD) orthoimagery to meet ASPRS Class II horizontal accuracy specifications at 1' = 50' map scale. The 3-inch pixel orthoimagery was produced to meet or exceed a horizontal accuracy of 0.7 feet RMSE according to ASPRS Positional Accuracy Standards for Digital Geospatial Data. Resultant orthoimagery was rectified to a DEM created from LiDAR collected in 2015 and 2017. Orthoimagery was delivered in GeoTiff tiles according to SEWRPC tiling and naming scheme. The project area covers approximately 2,258 square miles. Kenosha and Milwaukee counties were flown in a separate project by EagleView (formerly Pictometry). The Wisconsin Regional Orthoimagery Consortium (WROC) is a multi-entity group of county members and partners led by regional planning commissions (RPCs) and WROC representatives from Ayres Associates. The goal of the consortium is to build and sustain a multi-participant program to acquire digital orthoimagery and elevation data throughout Wisconsin. Orthoimagery was collected for SEWRPC 2020 to provide consistent deliverable products and accuracy standards for each of the participating entities.
