The Cleveland County Office of the Assessor’s Geographic Information System (GIS) has been in use since the early 1990s, and the ESRI (Environmental Systems Research Institute) software has been used since the beginning of today.
Currently, the GIS department maintains only one level of lots and plans to add new levels to more accurately locate and classify lots in Cleveland County Assessor.
Geographic Information Systems (GIS)
The location of the property is essential for the tax mapping process. Once the country is located, it must also be given its “name.” This is called packet identification. A good property description consistently and unambiguously locates one and only one property. In Oklahoma, the land is described by legally registered written descriptions or plans.
Township and Range Systems (also known as Township and Range Systems), Meter and Boundary Descriptions, or Coordinates Description Systems are all options for written land descriptions. Parallels and meridians follow the globe in this system. The equator and all horizontal north and s lines
Outside of these are known as parallels. The vertical lines that converge at the North and South poles are called meridians.
The rectangular topographic system also has meridians and parallels unique to the United States. The meridians are known as the “primary meridians.” A parallel accompanies each prime meridian, called a baseline. The points where these two meet are called starting points.
In Oklahoma, the land described with this system refers to the Indian or brown meridians.
The graphical descriptions of the country are based on the cadastre or map file. These are called “registered map descriptions” or “legally registered plans.” Record map descriptions are parcel descriptions referencing lot numbers (or letters) and/or block numbers (or letters) and names or numerical designations assigned to a record map or file.
