  • 2. What is a GIS?
    Geographic Information System
    Computerized Mapping
    Data that has “Place”
  • 3. What is GIS Drafting?
    Mapping a Legal Description in a GIS environment
    Commonly:
    Individual Properties
    Political Boundaries
    Areas of Interest
  • 4. What is a Legal Description?
    The official written words which delineate a specific piece of real property.
  • 5. Metes & Bounds
    A legal description where the boundaries are described by working around the parcel of the land in sequence, starting with a point of beginning, then describing individual calls, and finally returning back to the point of beginning.

  • 6. Example Description 1
    Sec. 24, T16S, R24W: 3.33 acres, more or less, described as beginning at the SW/c of the NW/4 of the SE/4 of said Section 3, thence East along the Subdivision line 14 chains and 65 links, thence South 50 Yards, thence West 14 chains and 65 links; thence North 50 yards to the point of beginning, AND 10.00 acres, more or less, described as commencing at the NW/c of SE/4 of said Section 3, thence South 7 chains and 89 links to the point of beginning, thence South 12 chains and 11 links, thence East 14 chains and 65 links, thence North 1 chain and 66 links, thence North 54 degrees 30 minutes West 18 chains to the point of beginning, all located in Lamar County, Alabama.

    THENCE, with said south line, S 89°07'17" W 1317.19 feet to a point;
     
    THENCE, leaving said south line, N 00°52'43" W 5413.85 feet to the POINT OF BEGINNING;
     
    THENCE, with the perimeter of this 160.0 acre tract,
     
    West 2350.89 feet to a point,
    North 3486.28 feet to a point,
    East 1133.40 feet to a point on the west bank of the Aransas River;
    THENCE, with the meanders of said bank,
     
    S 23°18'29" E 773.37 feet to a point,
    S 32°11'08" E 295.36 feet to a point,
