Abstract: A method of spatially indexing land by selecting a parcel (100) of land and extending its boundaries (110) to include a portion of adjacent streets (125) and alleys (122) to define a cell (150). A unique identifier is assigned to the cell as well as a reference point (170) within the cell (150). The reference point has a known location in a global referencing system. An internet address is assigned to the cell which identifies its location, such as the location of the reference point within the cell. This information and other data associated with the cell is then stored in an OX Spatial Index database and includes the street address for the cell and other relevant information such as owner, what type building if any is on the property, location of utility lines, etc. A Spatial Internet Address which includes the geographic location of the cell is assigned for each cell and this information is also stored in the index.
