  1. The Future of GISinWest Virginia Think Geospatial Collective

  2. The problem How can West Virginia entities implementing GIS utilize their existing geospatial investments more effectively? To understand where we want to go we must first look at where we came from 

  3. The beginning ofWest Virginia GIS • There was a single desktop • Then… there were more • Next came the file server & the LAN • But we outgrew that! DEP file server DEP LAN

  4. Remote LAN n Remote LAN 2 • So several years ago DEP created the first SDE/RDBMS deployment in West Virginia. Remote LAN 1 Remote LAN 3 • But field office access to ALL data for 50 to 100 people was still a huge bandwidth issue. • Sharing licenses was desirable but also not easy. DEP SDE DEP LAN

  5. Working in a collective … DEP’s 1st. step was over a decade ago. • Office of Surface Mining Technical Information Process System (TIPS) • Multi million dollar pool of technical computing licenses (including Arc/INFO) shared by: • two OSM Regional Offices (Pittsburgh & Denver) • twenty-three coal producing states • five native American tribes I need to run Arc … can I have a license? You got it Thanks!!! DEP LAN OSM LAN Denver, CO License server

  6. So … Citrix (terminal services) Citrix DEMO B • How does it work? • Applications install and run 100% on server (A) • Only screens, mouse clicks and keystrokes travel the network (B) • Applications accessed from desktop PC or thin clients (C) C Can be combined with Virtual Private Network (VPN) and used anywhere A

  7. Recently several State agencies have successfully deployed additional SDE/RDBMSs RTI SDE RTI LAN • SDE servers provide enterprise level performance encapsulating spatial data into a RDBMS. DEP SDE DEP LAN

  8. Back to the present and … how can West Virginia entities implementing GIS utilize their existing geospatial investments more effectively? One possible answer is 

  9. The West Virginia GISB-ORG =Broadband-Orchestrated Regional Group Your SDE server’s technological distinctiveness will be added to our own.

  10. How Does the B-ORG Work? • The hive provides the ability to access geospatial data using broadband access to SDE servers outside your Agency • SDE end users could be federal partners (OSM already accesses WVDEP’s SDE server), state, county, higher education (NRAC also accesses WVDEP), etc. RTI SDE RTI LAN WV Backbone DEP SDE • The potential exists to add to the collective. DEP LAN

  11. Network design planning factors • DC client = standard ArcGIS desktop client, data from SDE, using ArcSDE direct connect to DBMS • AS client = standard ArcGIS desktop client, data from ArcSDE installed on the server • Terminal client = access to ArcSDE running on Windows Terminal Server. Data required to support display = 100 KB per query. • Browser client = access to a standard ArcIMS image map service. • Web GIS client = ArcGIS desktop client access to a standard ArcIMS image map server.

  13. Network design planning factors Option using smallest bandwidth and providing most technical capabilities

  15. How well does it work? First test of B-ORG concept SDE connection testing DEP to RTI – Jan 17, 2006

  16. B-ORG DEMO

  17. So join the West Virginia GIS Broadband-Orchestrated Regional Group (B-ORG) ... a collective of SDE servers empowering State government agencies with the ability to access each other's remote geospatial data more efficiently.  To become part of the hive you will need a collective user id and logon. Resistance IS futile
