1 The Future of GIS in West 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 There was a single desktop DEP LAN Then … there were more The beginning of West Virginia GIS Next came the file server & the LAN DEP file server But we outgrew that!

4 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 So several years ago DEP created the first SDE/RDBMS deployment in West Virginia. DEP LAN Remote LAN 1 Remote LAN 2 Remote LAN 3 Remote LAN n

5 Working in a collective … DEP’s 1 st. 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 DEP LAN OSM LAN Denver, CO License server I need to run Arc … can I have a license? You got it Thanks!! !

6 So … Citrix (terminal services) 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 A B Can be combined with Virtual Private Network (VPN) and used anywhere Citrix DEMO

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

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 GIS B-ORG = B roadband- O rchestrated R egional G roup Your SDE server’s technological distinctiveness will be added to our own.

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

11 Tomlinson, Roger., Thinking About GIS: geographic information system planning for managers, CA: ESRI., 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.

15 How well does it work? First test of B-ORG concept SDE connection testing DEP to RTI – Jan 17, 2006 TestTime in seconds Load/display County layer 20 Load/display Roads (TIGER) 96 Pan & redraw (~ 10 mile extent) Select Roads in Kanawha County 24 Export selected Roads to local shapefile 27

16 B-ORG DEMO

17 So join the West Virginia GIS B roadband- O rchestrated R egional G roup ( 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
