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

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.

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.
