Geography
Derek Peddle’s primary research
interests are in the fields
of remote sensing, GIS, and Earth System Science modeling
in studies of global environmental change.
Using an integrated
research approach, key environmental indicators are being investigated in different parts
of the world at dynamic spatial and temporal scales.
Current attention is focused on forested
ecosystems, agriculture,
water, and mountainous terrain.
Airborne and satellite image processing linked with spatial
and multi-temporal GIS data analysis are used to extract
environmental information at spatial scales ranging from
centimetres to regional, continental and global areas. This
research also includes development of new algorithms and
software towards maximising the contribution of remote
sensing
and geographical information extraction in regional and
global change studies.
Opportunities exist for undergraduate and
advanced graduate
level training and research in these fields. Together with
new research initiatives, collaborative ties have also been
established with national and international scientists and
agencies.
This research program
has received support from the following
agencies / programs:
- Remote
estimation of forest
biophysical parameters (biomass, LAI, NPP) in studies of
biospheric-atmospheric exchange within the global carbon
cycle.
- Spectral mixture analysis and
canopy reflectance modeling of airborne and
satellite imagery
- Field studies:
analysis of
understorey reflectance in boreal forests
Collaborating scientist with
NASA Goddard Space Flight Center.
- Alpine and
montane land classification
and biophysical analysis using remote sensing
-
Digital terrain modelling and
image texture analysis
- Modeling
permafrost distribution
and active layer depth
- Deriving new
hydrological and
climatological variables using GIS
Study Areas:
Colorado Rocky
Mountains, USA.
Appalachian
Mountains, Eastern
Canada.
- Spectral mixture analysis of
agricultural crops
- Multiscale field and airborne
remote sensing of biophysical properties
- Use of GIS, GPS in Precision
Agriculture and Water/Irrigation Studies
- P.I. on 2 Alberta Ingenuity Centre for Water Research (AICWR) projects.
To facilitate
advanced research
applications, I design and implement new algorithms in
software
which are not available in commercial remote sensing image
analysis and GIS packages. This has
involved software development
for:
-
Geomorphometric processing
of digital elevation models
- Analysis and classification
of multisource data (e.g. GIS, optical/radar
imagery, DTM)
- Data processing
and analysis:
radar noise detection, sampling, reflectance
processing,
- Spectral Mixture Analysis and Canopy Reflectance Modeling of Biophysical Structural Information

There are potential graduate school and other opportunities for qualified and motivated individuals including Masters, Doctoral, Post-Doctoral and other staff posts.
Environment for Graduate Student and Post Doc
Training:
D.Peddle’s research lab is well
equipped with graphic workstation
computers, PCs, and a variety of GIS and remote sensing
software and peripherals (e.g. PCI, ENVI,
ARC-GIS, ARC-INFO
/ View, Map-Info, large roll plotter for posters, etc.).
Highly detailed spectral measurement of ground samples is
achieved in a Spectroradiometry Laboratory for dedicated
studies and field/model validation of remote sensing image
products. Field and laboratory equipment includes ASD-FR
Spectroradiometers, a Trimble ProXRS Global Positioning System
(GPS), a hemispherical digital photography system, a TRAC
system and LAI-2000 units for obtaining LAI information, access to a field portable and laboratory goniometer for BRDF studies, as well as a variety
of other field measurement instruments.
In 2010, the University of Lethbridge was awarded a 6 year NSERC CREATE Grant. The NSERC Collaborative Research and Training Experience (CREATE) Program on Advanced Methods, Education and Training in Hyperspectral Science and Technology (AMETHYST) provides a variety of opportunities for undergraduate, M.Sc., Ph.D. and PDF trainees, including internships with our international partners.
I am currently National Past-Chair/Président on the Executive of
the Canadian Remote Sensing Society
(CRSS) / Société canadienne de télédétection (SCT), having previously
served as National Chair, Vice-Chair, Secretary-Treasurer and Prairie Provinces Regional Chair (Alberta, Saskatchewan, Manitoba).
My main personal
interest is
my family: my wife and 2 children, and our dogs (Labrador
Retrievers), cats (~2) and various other creatures. I also enjoy league sports
(especially ice hockey and soccer) and outdoor recreation
such as mountain biking, skiing, scuba diving, hiking, and
exploring the large river valleys and parks in and around
Lethbridge as well as the diverse landforms and nearby Rocky
Mountains of southern Alberta and south-eastern BC.
