  1. 2. Describing and Mapping Land • In this module, we will discuss: • Three means of describing real estate • Types of maps available to land-use professionals and how to read them

  2. Metes and Bounds • Oldest means of describing real estate in the U.S. • Used in original 13 colony states • Presented in running prose style • Landmarks and features mentioned in the description may relocate or no longer exist • Least accurate method of describing real estate

  3. Lot and Block • Used to describe parcels, usually city lots, within a large tract • Based on a plat map • Municipalities usually base real estate taxes on the lot and block system and assign tax identification numbers (TINs) or tax parcel numbers based on it

  4. Rectangular Survey • Used in states that lie west of original colonies • Symmetrical and orderly • Principal meridian is a true north-south line • Adjustments must be made for earth’s curvature

  5. Topographic Map • Shows the contours and elevation of the land • Contour lines and symbols are drawn to show natural features

  6. Aerial Maps • Bird’s eye view of the land • Provide a “stop action” viewpoint, when looking at land-use progression environmental and wildlife habitat preservation or degradation

  7. Location Maps • Street and highway maps

  8. Plat Maps • Plan for a tract of land, such as a township or a subdivision • Plat maps are drawn to: • Designate roads • Assure access to property • Create easements • Establish/assure compliance with zoning, regulations, and lot size • Plan access to public utilities, water, and sewer hookups

  9. Soil Surveys • Not a type of map, but include detailed soil maps • Show the presence and distribution of types of soils

  10. Soil Capability Classes

  11. Soil Texture Triangle

  12. Flood Maps • Developed by FEMA for flood plain management and insurance purposes • Risk areas are rated high risk A, moderate to low B or C, coastal V, or undetermined D. • Can be obtained through the FEMA Map Service Center at http://msc.fema.gov

  13. Geographic Information Systems (GIS) • Computer-based tools for mapping and geographically analyzing objects and demographic patterns
