Newest Spatial Data Set Being Developed by WVDEP EQuIS is an

Oracle database system containing environmental sampling locations & results

Surface water samplesGroundwater samplesGeology samples

Groundwater concentration of Benzene displayed in ArcGIS as colored contours

Statewide Users Benefited from 2003 Improvements in the Interactive MapperIn 1995 WVDEP pioneered WWW-based mappingWe continue that tradition today

Search via GNIS databaseSearch by County (new)Search by watershed (new)

Open Dump Project Results in Multimedia Benefits for Users

Accomplishment 1: Number of ArcGIS Users Expanded Significantly in 2003

Estimated power and frequent users at the beginning of 2003 was ~ 65.During the year we added about 65 occasional and new users.Projected increase in users in 2004 is expected to be ~ 50.

Accomplishment 2: ArcObjects Customized Applications Development

Fielded WVDEP’s first, custom built, enterprise spatial application for the Division of Mining & Reclamation (DMR) in 2003.

Majority of new 2003 GIS users were DMR permitting staffTrained ~ 60 people to use DMR’s new application

Currently developing custom apps for Offices of Abandoned Mine Lands & Reclamation and Special Reclamation.Increased TAGIS’ Spatial Applications Development Group from 1 to 2 people doing full time spatial development work in early ‘04.

Accomplishment 3: IFSAR High Resolution Elevation Data Acquisition

1.25 meter resolution Orthorectified Radar Imagery (ORI) produced

from X-band radar data collected in September 2003 by InterMAP

30 meter resolution DEM produced from data collected in the 1970s (part of Williams Mountain Quad)

Goal 1: Migrating GIS Data Archive from RAID to a Storage Area Network (SAN)

SAN greatly improves both quantity of data we can store and the speed at which we can serve data to end users.
