Airborne LIDAR mapping
tools, technology, trends, outlook
ASPRS Annual Conference – PDAD Airborne LIDAR Mapping Technology Panel
April 30, 2008
ALS50-II Airborne LIDAR Scanner
continued innovation, expanded performance
Breakthrough system design allows 150
kHz pulse rate with no loss in accuracy
Multiple Pulse in Air (MPiA) technology
 carries 150 kHz performance to 1569
m AGL
 2x pulse rate improvement over
conventional systems altitudes above
1400 m AGL
Improved 90 Hz maximum scan rate
Fully integrated FCMS flight navigation
with airborne-certified displays
Compact electronics
Simple 3rd-party sensor integration using
embedded IPAS10 GNSS/IMU subsystem
2
ALS Corridor Mapper
responding to emerging markets
Uses key ALS technologies
1000 m AGL maximum flying height
High accuracy and high point
density, even at maximum flying
height
Corridor or “large-map-scale”
applications
Lower price point
3
RCD105 Digital Frame Camera introduction
39 MP: fast, flexible, plug-and-play with ALS50-II
Purpose-designed airborne camera
Fast 2.02 second frame interval
RGB or CIR operation
User-replaceable 1/4000-sec shutter
35, 60 and 100 mm lenses
4
Significant milestones
technology put to work

MPiA is now a mainstream
technology
Huge projects being undertaken w/
MPiA systems (Example – NWG has
collected 315,000 km², 835 aircraft
hours, 1 point / m², 750,000 km²
collection)
Number of new system
deliveries/demos for high altitude
use @ 4500 m – 6000 m AGL
4500 m AGL, MPiA, 66º FOV, 1.5 m avg. post spcng

Rate at which LIDAR systems are
entering the market is doubling
every 3-4 years
Units sold
~249 LIDAR systems sold (total
market) since mid 1990s
LIDAR trends
what are the application market trends?
Increased interest in infrastructure
measurements
 Railways
 Roads
 Power lines
 Pipelines
National forest inventory
 Biomass
 Carbon uptake
8
LIDAR trends
what are the technology trends?
Point density  laser pulse rates
doubling every ~2 years
Point accuracy  customers
pushing the limits of technology,
but limited by GNSS accuracy
 Availability of high-accuracy
position data increasing with
introduction of GPS + GLONASS
 Increasing use of “fitting”
software (e.g., TerraMatch)
Regulatory issues  import/export
getting easier to deal with due to
wider IMU availability
9
Use of auxiliary sensors  over
50% of LIDAR systems have
integrated imaging sensors
 Medium format
 Large format
 Multispectral
 Thermal
Processing speed  increasing
number of 3rd-party workflow
suppliers
Outlook and summary
Demand for data is still increasing
LIDAR and medium format camera systems continue to show rapid
increases in performance
Point density and point acquisition speed (i.e., pulse rate) continue
to dominate in the field of new features the market is demanding
New processing architectures are making inroads, but no obvious
replacements for current processing methodologies
