Geospatial Technologies …
How They Relate to the West Virginia Forum on Statewide Water Sampling Programs
Topics to be explored
• Pertinent history
• Recent policy changes
• Geospatial technology advancements
In the beginning .......
• Before WVDEP’s Environmental Quality Information System (=EQuIS)– Individual PC-based sampling databases– All were one hard drive failure from
extinction– No serious database design
Environmental Quality Information System (EQuIS)
• After EQuIS– Enterprise, server-based sample results
database– Proper backup of mission critical data– Serious database design
WCMS hooks to EQuIS
• See http://www.nrac.wvu.edu/projects/nrac244/index.html for an explanation of WCMS and …
• http://www.nrac.wvu.edu/projects/nrac244/files/NRAC244_tech_manual_v9.pdf for a User’s Manual
Example of overland flow analysis conducted using WCMS showing potential runoff from surface mine
sites
Things happen
Moving forward …
Late 2008 - Now
• Division of Mining & Reclamation’s eMaps– Submittal of active mining permitting data
electronically mandated January 1 of 2009• Surface water sampling points• Groundwater sampling points
– Revised WVDEP’s Geospatial Policy end of ‘08

• Distributed computing geoservices
Geoservices that can be engineered Geoservice Example Description
Map Services Serves cached maps and dynamic maps from ArcGIS.
Geocode Services Finds address locations.
Geodata Services Provides geodatabase access, query, updates, and management services.
Geoprocessing Services
Provides spatial analysis and data processing services.
Globe Services Serves digital globes authored in ArcGIS.
Image Services Provides access to image services.

What is the West Virginia Geospatial
B-ORG?
B-ORG = Broadband-Orchestrated Regional
Group
Your ArcGIS/SDE Server’s technological distinctiveness will be added to our own
DEP SDE
DoT SDE
• The hive provides the ability to remote access geospatial data using broadband access to ArcGIS Servers outside your Agency
• The potential exists to add to the collective.

WV Backbone
RTI SDE
GeoServices Model is the Future
Mining data from WVDEP’s server
• Data from three servers comingled with real time spatial analysis now possible!

So join the West Virginia GIS Broadband-Orchestrated Regional Group (B-ORG)
... a collective of ArcGIS Server-based geoservices empowering West Virginia with the ability to access remote geospatial data more efficiently. To become part of the hive you will need a collective user id and logon.
Resistance IS futile
