Hawaii Pacific GIS Conference 2012: LiDAR for Intrastructure and Terrian Mapping - Maximizing the Benefits of LiDAR Data in GIS

  1. 1. Maximizing the Benefits of LiDAR with GIS Presented by Steve Snow Esri Industry Specialist
  2. 2. Agenda• What is LiDAR• Different types of LiDAR systems• Challenges to working with LiDAR data• How GIS organizations work with LiDAR• Example GIS-LiDAR applications• A New Vision Is Emerging• Summary/Questions
  3. 3. LiDAR – Light Detection And Ranging Optical remote sensing technology that measures the distance from the sensor to a targetLAS: Binary file format for LiDAR data storagedeveloped by the ASPRS in conjunction with private andgovernment stakeholders
  4. 4. Types of LiDAR• Airborne - Captured from aircraft• Terrestrial and Mobile - Captured from the surface
  5. 5. LiDAR Technology
  6. 6. LiDAR DataVery rich, but contains a lot of data not required for many applications First Return SecondReturn ThirdReturn Last Return
  7. 7. LiDAR DataVery rich, but contains a lot of data not required for many applications First Return DSM SecondReturn ThirdReturn Last Return
  8. 8. LiDAR DataVery rich, but contains a lot of data not required for many applications First Return DSM SecondReturn ThirdReturn DTM Last Return
  9. 9. Challenges of Working with LiDAR Data• Huge data volumes• Storing & serving• Integration with other spatial data• How to manage?• How to access?• How to analyze?
  10. 10. Traditional Workflows • Project based: - Collection – Project based - Analysis – For specific project
  11. 11. Traditional Workflows • Project based: - Collection – Project based - Analysis – For specific project - Archive data
  12. 12. Traditional Workflows • Project based: - Collection – Project based - Analysis – For specific project - Archive data - Move on to next project
  13. 13. Traditional Workflows • Project based: - Collection – Project based - Analysis – For specific project - Archive data - Move on to next project • Data not accessible to - Multiple applications ? - Multiple users • Value is lost
