Answers
1. What does the term LiDAR stand for?
LiDAR stands for Light Detection and Ranging.
2. What does the term panchromatic mean?
Panchromatic is a descriptive for all wavelengths of the visible spectrum.
3. Data from remote sensing is a powerful tool for analysis. What has
prevented it from being more widely taken advantage of?
Remote sensing data is costly to produce.
4. What is the oldest commercial satellite system that is still in use?
The oldest commercial satellite system is called “Landsat.” The first satellite
of this system was launched in July 1972.
5. What is the size/scale of geographic area most well-suited to being
studied using remote sensing data? Small, medium, or large?
Generally, remote sensing data is most useful for studying large areas.
6. What remote sensing technology is being used in modern surveying?
Surveying now uses laser sensors for accurately measuring distances.
7. What were some early applications for radar-based remote sensing?
Some of the first applications for radar-based remote sensing were climate
analysis, iceberg detection, and geology.
8. What is the highest resolution panchromatic remote sensing now
available?
