Introduction (cont.)

• Mixed GIS application standards
• ESRI
• Mapinfo
• OpenGIS, QGIS, uDig, GRASS, etc
• Mixed data type
• .shp
• Cad
• Geo-tif

4
Problems

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

5
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

6
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 Citys 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

11
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
• (210772)Mb 55 conties 54 Gb
• 54Gb 2 108 Gb

Conclusion

• Support and carry on other WV GIS projects.
• Provide a faster means to organize, to maintain,
  and to manage the GIS system
• Furnish the ability to access, edit, and share
  information with a click of a button.

Future project

• Huntington Crime analysis using PostGIS and dojo
  framework
• Real time speed synchronizing app (Android,
  iPhone, Window Mobile, google)
• GIS robotic controlling by Mobile Apps and VNC
  software
