Bridging the digital divide in WVGIS GIS used in WV (Wood County Assessor, 2009)

Bridging the digital divide in WVGIS Introduction (cont.) Mixed GIS application standards: ▫ESRI ▫Mapinfo ▫OpenGIS, QGIS, uDig, GRASS, etc Mixed data type: ▫.shp ▫Cad ▫Geo-tif

Bridging the digital divide in WVGIS Problems With the current technologies and applications, WV GIS agencies had some difficulties in: ▫Sharing information ▫Reusing information across the system.

Bridging the digital divide in WVGIS Project Purpose Develop an efficient and cost effective solution to help: ▫Share data ▫Save time and storage space ▫Provide public access at convenient locations ▫Provide references to other research

Bridging the digital divide in WVGIS Solution Using a combination of commercial and openGIS standard ▫Set up a multi-tier GIS server system ▫GIS Map Server for Web map application services Beckley City’s Metro GIS system at Raleigh county is an example of successfully applying this system

Bridging the digital divide in WVGIS Results Public user can have access through the Web site (Cabell Assessor, 2009)

Bridging the digital divide in WVGIS Results (cont.) Save millions of dollars by reusing data and resources. Example: ▫$3 * parcels = $180,000 ▫$180,000 * 55 counties = $9,900,000

Bridging the digital divide in WVGIS Results (cont.) The multi-layer GIS system can support different GIS projects Save from 7 to 10 days until receiving the mail data or save several months or years by not building again Save lots of spaces: ▫( )Mb * 55 conties = 54 Gb ▫54Gb * 2 = 108 Gb
