Title: Soil Expansive
Contributors:- Polygon data
- 2011
Summary: Expansive Soils are defined as Maximum Measured Shrink-Swell Potential and were grouped by consultant Sean Wilson, geologist. Data originates from the NRCS Soils data known within the County of Marin GIS database as Soils. NRCS soils were downloaded from ftp://ftp.tfw.nrcs.usda.gov/pub/ssurgo/online98/data/ca041/ . This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.

Contributors:- Raster data
- 2013
Summary: This layer is a georeferenced raster image of the historic paper map entitled: Map of City of Medford, Massachusetts, Paul O. Hadsel, Chief Engineer. It was published by Chief Engineer in 1980. Scale [ca. 1:12,250]. 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, city, ward, and precinct boundaries, selected buildings, parks, cemeteries, and more.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.
