Working in SW Riverside County using public domain county and/or city gis data and non-attributed county parcel dataset (public records act) to establish city, park, retail, commercial and industrial boundaries on a city-by-city basis (no bulk importing). Correcting road alignments via Yahoo as needed, adding missing roads as needed, will follow up with field surveying for streetnames and poi's as time permits. Adding/revising known road and poi names as appropriate based on local knowledge. Please feel free to contact or provide sugestions.
