GIS used in WV

(Wood County Assessor, 2009)


Introduction (cont.)

•Mixed GIS application standards:▫ESRI

▫Mapinfo

▫OpenGIS, QGIS, uDig, GRASS, etc

•Mixed data type:▫.shp

▫Cad

▫Geo-tif


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


GIS System

Discussion


Discussion (cont.)•Data center


Results•Public user can have access through the

Web site

(Cabell Assessor, 2009)


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


Scenario 1: Cadastral layer with Geomajas, PostGIS and Tomcat 6 •http://172.16.6.23:8080/majas-tutorial/

Scenario 2: GIS and 3G network•Crime mapping:

Scenario 2 discussion

•OpenSource : Ubuntu server 9.10, PostgreSQL 8.3, PostGIS 1.4, ...

•Functionalities: Add, Edit, analysis• iPhone SDK•3G or 4G services•GPS accuracy


iPhone GPS accu.

•Cell tower: <500m•internet: <30m•GPS: <10m

(iGPSd, 2010)


And also save life


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
