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

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

Solution
•Using a combination of commercial and openGIS standard▫Set up a multi-tier GIS server system▫GIS Map Server for Web map application
servicesBeckley City’s Metro GIS system at Raleigh
county is an example of successfully applying this system

Results (cont.)
•Save millions of dollars by reusing data and resources.
•Example:▫$3 * 60000 parcels = $180,000▫$180,000 * 55 counties = $9,900,000

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:▫(210+772)Mb * 55 conties = 54 Gb▫54Gb * 2 = 108 Gb
