  1. Introduction to GIS/GPSforPublic Safety ApplicationsNorthern Buttes District Oroville, CAOctober 10, 2012

  2. Presentation Outline • Enterprise GIS (eGIS) Highlights :10 • GPS Demo/Exercise 1:00 • Questions & Discussion :30

  3. California State ParksEnterprise Geographic Information System

  4. Background Image : California -- Looking Northeast Spanning 1200 kilometers (750 miles) from the Humboldt Redwoods to Anza-Borrego, the state is outlined over earth imagery, undersea features, and points representing over 270 State Park Units and 1.5 million acres of land. Lake Tahoe Anza-Borrego Desert Humboldt Redwoods N Monterey

  5. California State Parks GIS professionals synthesize visualizations like this one using diverse geospatial data in a service-oriented, information technology architecture. Building upon this infrastructure, an enterprise geographic information system (eGIS) team supports Parks and their partners in managing nearly one-third of California's coastline and the state's finest examples of natural and cultural resources.  Each year, the state’s economy depends on the benefits from these recreational and educational opportunities, enjoyed by millions of Californians and visitors from around the world. 

  6. To address population and climate changes, California State Parks emphasize the common ground of geography and visualization to facilitate decisions in a complex network of government and private concerns. In such diversity of values, often the element of location is the most widely shared. Thus, in offering maps and imagery, State Parks leads by example and contributes to timely and effective solutions for the life-safety, resource protection, recreation, and educational needs of present and future generations.

  7. Definition: An enterprise Geographic Information System (eGIS) consists of • Specially-trained teams of people • Mobile-, workstation-, & wide-area computing • Global Positioning Systems (GPS) • Data, and • Procedures to • Collect • Analyze, and • Report geospatial information with • Shared databases and • Web services

  8. The California State Parks eGIS eGIS GIO

  9. The California State Parks eGIS: • Serves multi-disciplinary, department-wide functions • Maps the location of department assets in all databases • Enhances visual learning by integrating maps & images with: • COM Center Geographic File – Public safety dispatch • Unit Data File – Parks’ internal, corporate knowledge base • CAMP – Computerized Asset Management Program • Supports Field-owned, HQ-managed, GPS data acquisition • Informs emergency management by Parks & partners in • Life Safety • Resource Protection (Cultural & Natural) • Public Education • Delivers interagency support through our Information Technology Office & Geographic Information Officer (GIO)

  10. Example eGIS Applications • Planning • Land Acquisition • Facilities Management • Emergency Management

  11. Introduction to GPS • Concepts • Latitude / Longitude – Various Formats • Universal Transverse Mercator (UTM)

  12. Concepts • LENGTH – Trails fundamentals; position; map; location; proximity to hazards or sensitive sites • MASS – How “heavy” are your data: Trail type, use, complexity of networks, junctions, signage • TIME – Date of photos and positions; seasonal use; project schedules, and • SCALE – The closer you are, the more detail you “see” and the “less” of the whole is visible

  13. Terminology Latitude / Longitude Formats (This is critical knowledge that could save a life) • H DDD° MM' SS.S“ Hemisphere, Degrees, Minutes, Seconds N 32° 18' 23.1" W122° 36' 52.5" (USGS quads) • H DDD° MM.MMM‘ Hemisphere, Degrees and Decimal Minutes N 32° 18.385' W122° 36.875' (GARMIN default) • H DDD.DDDDD° Hemisphere, Decimal Degrees (GIS Users) N 32.30642° , W 122.61458° For all of California - Think “10 by 10”

  14. LAT / LON : Decimal Degrees : The California domain 124 120 114 For all of California - Think “10 by 10” “32 to 42 Degrees North by 114 to 124 Degrees West” 114 – 124.4 Degrees WestLongitude 32.5 – 42 Degrees North Latitude

  15. Now go UTM statewide -- Zone 10 or 11 ; S or T ?? West 120 Degrees Longitude

  16. UTM statewide -- Zone 10 or 11 ; S or T 10 T 11 T 11 S 10 S

  17. X Anatomy of UTM Zone - MGRS Easting Northing 10 S 0559741     4282182 4281000m N Easting or “over” 560000m E Northing or “up”

  18. GPS Demo Trimble GeoXH Ricoh 500SE GPS PhotoLink 4.3 Trimble Juno SC Ricoh 500SE Garmin Nuvi 255W Use with Confidence: Accuracy & Attributes Meet or Exceed Department Standards Garmin 76 S Cost & Complexity Use with Caution As Backup Only

  19. Software: GPS PhotoLink v4.3 • “AutoMatic Lat/Lon” • via built-in GPS • or… • “Manual Lat/Lon” • Google Earth • Your GPS • Your ArcGIS • Your Map…

  20. Products : Image Content, Location, Time

  21. Photo & Map integration….

  22. Outdoor Exercise • Four Groups • Four Baselines (Feature-to-Feature) • Mark A & B Waypoints for Each Baseline • GPS – Photo Link Demo

  23. Instrument Cross-Check • Establish baseline with measuring Tape • Mark Waypoints at both ends, A & B • Compare Tape measure to difference in UTM Easting or Northing (A minus B) B A

  24. Discussion: GPS “Quick Survey” • Likes (Strengths) • Concerns (Weaknesses) • Suggestions (Opportunities)
