Active Microwave & LiDAR
(Ch7: 204-243)
- What
are two unique capabilities of active radar sensors?
- What are
two unique capabilities of SLAR?
- A synthetic aperture radar operates on the principal
that objects within a scene are illuminated by the radar over an interval
of time. True/False?
- Why is
the notion of "spectral signatures" difficult to apply in the context
of radar imagery?
- Lidar can accurately record what three components that allow creation of an image-like array representing
variation of elevation?
- Radar
imagery is a distinctive form of remote sensing. What are some advantages
of acquiring imagery using active microwave sensors and how have these
advantages been applied to improve other interpretations?
- Define:
depression angle, far-range & near-range side of the image,
slant-range distance, ground-range format, and the concepts of
ground-range domain & Slant-range domain.
- Discuss
wavelength as it relates to the nature of the radar image; explain further
resolution and antenna length in a real aperture system and the implied
design limitations.
- Relate
the advantages and disadvantages of using a Synthetic Aperture System.
Briefly explain the defining characteristic of the SAR system.
- What
advancements have recently made it possible to develop remote sensing
LIDAR for the collection of surface imagery? Briefly explain. How has
LIDAR data been applied and what unique property can it reveal regarding
vegetation? Briefly explain.
Land Use & Land Cover (Ch19: 554-586)
- What
is land use? What is land cover?
- What
are mapping unit descriptions? How are mapping units defined?
- Name two
LULC datasets that are based on MRLC data.
- What
are the ways of doing land-use/cover change detection?
- What
are change magnitude and direction in spectral change vector analysis?
Vegetation Mapping For Change Detection On
An Arid-Zone River
- What are
the main deficiencies of the Anderson-Ohmart
classification system?
- What
was the method used to quantify land cover classes within polygons?
- How
did the authors estimate plant height?
- What
was the main characteristic of plant associations that was used to
distinguish the primary land cover classes?
- NDVI
values could not be used to accurately separate plant types. However, NDVI values were proven to
differentiate an important characteristic in the images. What did the authors find that could be
differentiated by NDVI values? Why
the differentiation?
A remote sensing
and GIS-based model of habitats and biodiversity in the Greater Yellowstone Ecosystem
- What
did the authors cite as a weakness in traditional GAP analyses procedures?
- Why
did the authors select plants as one of their study groups?
- Explain
how these seemingly small details could have affected the findings of this
research?
- Why
did the authors choose butterflies as a study group?
- Why did the authors chose the Yellowstone Ecosystem?
