This data layer portrays the tax parcel boundaries in San Mateo County. Lynx
Technologies, Inc. compiled this data layer in 2000-2001. Lynx compiled the parcel layer
from County AutoCAD drawings and Fire Run maps as well as electronic data supplied by Cities
within the County. The final parcel layer was adjusted to best fit the County’s
200-scale orthophotography base. APN attribution is derived from data within the
Assessor’s database. Farallon Geographics converted all data from ARC/Info coverages
into Oracle Spatial. San Mateo County Assessor Department currently maintains the Parcel
layer.
