Title: Zoning District Map, Wilmington, Massachusetts, 1983 (Raster Image)
Contributors:- Raster data
- 2014
Summary: This layer is a georeferenced raster image of the historic paper map entitled: Zoning district map, town of Wilmington, January 1983, Robert L. Higgins, Acting Town Engineer. It was published by the Town Engineer in 1983. Scale [ca. 1:14,400]. 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, and more. Includes also street names, zoning districts, and hand-drawn annotations. 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.

Title: Minnesota Land Cover Classification and Impervious Surface Area by Landsat and Lidar (2013 Update)
Contributors:- Vector data ; Raster data ; LiDAR
- 2016
Summary: This is a 15-meter raster dataset of a land cover and impervious surface classification for 2013, level two classification. The classification was created using a combination of multitemporal Landsat 8 data and LiDAR data with Object-based image analysis. By using objects instead of pixels we were able to utilize multispectral data along with spatial and contextual information of objects such as shape, size, texture and LiDAR-derived metrics to distinguish different land cover types. While OBIA has become the standard procedure for classification of high resolution imagery we found that it works equally well with Landsat imagery. For the objects classified as urban or developed, a regression model relating the Landsat greenness variable to percent impervious was developed to estimate and map the percent impervious surface area at the pixel level.
