What is GIS
Mobile GIS and Wireless Communications Tom Patterson ESRI Wildland Fire Specialist Deputy Chief (Ret) CA Desert District Overview •What is GIS? (Tactical Mapping) •Past •How it all started •What was “state of the art” then? •Present Where are we now? •Future •Where are we going? What is GIS (Tactical Mapping)? Habitat Resources Population Developments Vegetation Elevations A way to visualize, manipulate, analyze and display spatial data “Smart Maps” linking a database to the map Database – Not Easy to Interpret Geographic Information System GIS Creates “Spatial Relationships” Between Otherwise Unrelated Data Citizens Demographics Incident Types Visualizing information Together What is GIS? The capability to “layer” graphical information The ability to link other data and information to locations on the map What is GIS?

In the mid-90’s we discovered that if you connect a GPS receiver to a laptop computer, you could track yourself in a vehicle using some mapping software. We’ll never get lost again! A moving icon displays your position once a second and a “snail trail” follows showing where you’ve been. This GPS track log could then be converted into a shapefile as a polyline or polygon. Wow… wouldn’t it be cool to use this tool to map wildfires? Digital Mapping from the Air - City Creek Fire 1997 Trimble ScoutMaster 3 Channel GPS Pentium 120 MHz processor 1.26 GB HDD 32 MB RAM Present During the summer of 2005, CDD obtained waivers to purchase Panasonic Toughbook CF-29 ruggedized laptops. This model has a swappable HDD which complies with the intent of the DOI IT security policy. Authorization was also obtained to use wireless modem pc cards to transmit and receive critical information about on-going wildfire status while on the fireline. Engines and command vehicles were equipped with the notebooks which are removable and a secure, BLM-approved HDD can be inserted to connect to DOI net in the office. Handheld GPS receivers and GPS enabled digital cameras were also purchased. Do You Have All the Tools You Need? Required Equipment • LAPTOP COMPUTER • WIRELESS PC CARD MODEM • GPS/GPS CF CARD • SPATIAL DATA/ArcGIS • NG TOPO/STREET MAPS • SKILL (TALK WITH YOUR GIS PEOPLE) Additional Equipment • • • • DIGITAL CAMERA PORTABLE PRINTER POWER INVERTER CABLES Vehicle Mounting Systems • • • • COMMAND VEHICLES PREVENTION RIGS FIRE ENGINES USES PORT REPLICATOR AND MOUNTING BRACKET What It Does • REAL TIME LOCATION WHEN CONNECTED TO THE GPS RECIEVER • SHOWS LAND STATUS • SHOWS PROTECTION AREAS SUCH AS DPA/SRA/LRA • OVERLAY GPS TRACK LOGS ONTO LAND OWNERSHIP/DIRECT PROTECTION AREAS • HAS TOPO MAPS OF THE ENTIRE STATE OF CALIFORNIA • ALSO HAS MAP OF THE USA FOR FREEWAYS, HIGHWAYS AND LOCAL ROADS • LETS YOU SEE THE DISPATCH RUN CARDS What Else? • WIRELESS INTERNET ALLOWS YOU TO OBTAIN REAL TIME CURRENT WEATHER AND SITUATION REPORTS • LETS YOU UPLOAD MAPS TO FIRE MAPPING WEB SITES • YOU CAN COMPLETE AN IAP IN THE FIELD • IT WILL LEAD YOU TO THE FIRE AND THEN ALLOWS YOU TO GIVE ACCURATE DIRECTIONS TO OTHERS • PRINT TOPOGRAPHIC AND ROAD MAPS ON SCENE What Else? • THE CAMERA ALLOWS GPS PHOTO DOCUMENTATION • LETS YOU CHECK EQUIPMENT STATUS IN THE FIELD THROUGH GACC’S • ALLOWS YOU TO SUBMIT 209 FORMS WIRELESSLY • IT’S PORTABLE SO YOU CAN TAKE IT WITH YOU ! Present Training sessions were conducted at the CA Desert District Office and the Barstow College computer lab covering the Department IT security policy, Introduction to GIS (tactical mapping), digital photography, hyperlinking georeferenced images on a map, wireless communications and GPS for Emergency Management. Informal, hands-on training was also given at the Firehouse World Exposition in San Diego and the Heart ICP during the 2006 Sawtooth Complex.

A GPS-equipped PDA collects fire perimeter data and displays the tracklog in ArcPad. A digital radio connects to the PDA serial port and transmits locational information (NEMA GGA sentence) and unique identifier every 3 seconds. A simple GPS receiver connected to the radio will also transmit your location. A receive radio, connected to a PC, displays incoming data in ArcMap A GPS-equipped Tablet PC can use ArcMap to display and transmit data through a digital radio Long distance transmissions may be relayed through a digital repeater Digital radio repeater with external battery power supply Tablet PC, GPS card and SatPhone Paradise Fire Blaisedell Fire Look Ma, no GPS Technical Specialist!
