The GIS side of GPS… NWS Grand Junction, CO John Kyle DAPM/GIS Focal Point WFO Grand Junction
GIS ► Overview What we’re doing ► Internal – map displays ► External – web posting What we want to do ► Interface GIS with Google Earth ► Integrate (more) maps into ops. workstations ► Storm surveys/storm warning verification
GIS – Geographical Information System ► What is GIS? An integrated collection of computer software and data used to view and manage information about geographic places, analyze spatial relationships, and model spatial processes
Database (.dbf)
Plotting software - ArcView

Event mapping (curt. Becky Griffis WFO Omaha) ► Collect storm damage data points with GPS/PDA unit ► Input data via entry form interface input info on site ► Create a storm damage database ► Map it… post it Timeliness important - process will meet the demand for wx/damage graphics from local and national users
What is needed? ► Hardware GPS – to gathering data points PDA – for hosting data entry ► Software ArcPad – Mobile GIS

Hardware ► Trimble Recon ultra rugged handheld with GPS Pathfinder XC Kit 5-10 meter accuracy, add on for more $$ 400 MHz processor Integrated Bluetooth 256MB data storage with two compact flash slots avail. $2100 per unit ► Other misc. costs… Antenna, ArcPad extension, etc.
Storm warning verification curt. Brent M., OCWWS
Storm warning verification issues ► 88D displays accurately located, geographically? ► WX Spotter at Moab 5NW may actually be 4.5WNW Some don’t know exactly where they are ► Datum differences = spatial differences NAD27 vs. NAD83 ► ??
Where from here? “… will take the lead on designating a subcommittee to work on a draft for GIS proposal to blend/interface GIS with Google Earth” “… will take the lead on designating a subcommittee to work on a draft for GIS proposal to blend/interface GIS with Google Earth” ► Field offices need support to implement region, WSH, NOAAs GIS mission/vision Hardware Software Training Coordination ► Time… dedicated, not spare ► NOAA/NWS must stay relevant through GIS
Thanks!
