The G.L.I.S Landbase Information Systems Section is where the County of Orange Landbase is generated and updated. This unit prepares and maintains an information system consisting of a very accurate, parcel-level digital basemap containing over 665,000 parcels.
The Landbase contains street centerlines, right-of-way lines, and parcel boundaries, linked to text information, such as owner name, street address, and assessor parcel number. The foundation of this system is the County Control Network consisting of over 2400 control points on an approximate half-mile grid. This strong foundation makes the County Landbase very accurate and allows new map information to be added without losing any accuracy.
