  2. INSPIRATION (BLAME) • Shasta County Assessor’s CAD/GIS, 2004 • Pre-conference seminar, 2005 ESRI User Conference: “Cartography: Modeling GIS Data for Mapmaking” • Santa Cruz County Assessor’s GIS, 2005 • Los Angeles County Assessor’s GIS, 2007 • ESRI Coverage format • Sidwell Parcel Builder

  3. STAFF & STUFF WE STARTED WITH • ArcGIS (1 ArcInfo, 4 ArcEditors). • Server, ArcSDE, SQL Server in GIS dept. • Ambitious staff • One who is fairly proficient in ArcGIS and VB • One who is a logical, big-picture thinker • Three to cover our backs and take up the slack • All 5 well-versed in AutoCAD

  4. DATA WE STARTED WITH • 3300 CAD drawings (16900 maps total) • Polygon shapefile of land parcels • Converted polygons to lines • Generated parcel points (centroids) with APN • Section corners (Engineering Dept.)

  5. COST OF CONCOCTING • After a year-and-a-half, we estimate: • Thanks to slow economy!!! • 1920 man-hours of development time • About $55,000 in county wages • Compared to $288,000 in consultant fees
