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/nrac2 44/index.html

WCMS and … for an explanation of • http://www.nrac.wvu.edu/projects/nrac2 44/files/NRAC244_tech_manual_v9.pdf

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

Your ArcGIS/SDE Server’s technological distinctiveness will be added to our own

• • How Does the B-ORG Work?

The hive provides the ability to remote

access geospatial
