Remote sensing application in environmental planning
Remote sensing is the acquisition of information on the condition of land
from space (such as by way of aircraft, spacecraft, or earth observing
satellite).
Examples are weather satellites like the weather satellites operated by of
the American National Oceanic and Atmospheric Administration (NOAA)
or the early land observation satellite family of LANDSAT.
The earth observation system are varying in
1) the carrier of the scanner and the distance to the earth
2) the frequency of data capture
3) the type of spectral data collected and the resolution of the data,
4) and the size of coverages captured

Earth observation satellite LANDSAT
The Landsat program is the longest running earth observation satellite
program.
The first LANDSAT satellite was launched in 1972.
The most recent satellite of this family is called LANDSAT 7 and was
launched in 1999.
The images, of the American satellite archives in at Landsat receiving
stations around the world.
Technical data:
Size of coverage of Multispectral Scanner: 185 km X 185 km
Temporal Resolution:
16 days
Spatial resolution:
68 m X 83 m

LIDAR is an optical remote sensing technology of future interest
for landscape architecture applications.
The acronym Lidar stands for light detection and ranging.
LIDAR it is an airborne optical remote-sensing technology similar
to radar technology.
While Radar scanner are using radio waves, LIDAR scanner are
using much shorter wavelengths of the electromagnetic
spectrum, typically in the ultraviolet, visible, or near-infrared
range.
The LIDAR technology allows the measurement of threedimensional structures and the underlying terrain.
This will make data driven from LIDAR very useful in landscape
architecture applications
