Teaching
Several years after its inception, the Remote Sensing Unit expanded its
activities to include teaching. Primarily this involves offering a
course option to final year students of the B.Sc Civil Engineering degree
course. The option attempts to give students a brief introduction to
Remote Sensing and to indicate how remote sensing systems can be applied
to civil engineering. Emphasis is on current applications and in this
context students are trained in the Use of air photo interpretation for
highway route location, surveys of tips and quarries, and general land
use mapping. Most of this work tends to be qualitative in nature but
complements the compulsory photogrammetric work which students under-
take in earlier years.
In addition to formal teaching, the Unit offers several final year projects
with a remote sensing theme, which any final year student can choose to
study.
Other teaching has involved more specialised work in presenting short
intensive courses to bodies interested in the application of remote
sensing to environmental planning. Emphasis has again been on practical
applications and participants on the courses have been shown the uses of
various types of photography in urban land use mapping, derelict and waste
disposal site surveys, ecological evaluation and the survey of soils and
vegetation,
Experience has also been provided at an individual level to students from
the University of West Indies (UWI) under an exchange scheme whereby UWI
students attend the Remote Sensing Unit for a year of their postgraduate
degree course, and in return students from the Unit continue some aspects
of their research in Jamaica.
Research
As stated in the Introduction, the Remote Sensing Unit has concentrated
on research into the application of proven systems of remote sensing.
This is because most research projects have developed from a real life
problem which has required a solution within a given time of usually
less than a year. In addition projects have been carried out in co-
operation with agencies involved in environmental planning or resource
surveys (e.g. county planning authorities, waste disposal authorities).
These agencies, as well as using data collected by the Unit's research
staff, have needed to adopt the methodologies developed by those staff
for their own future use. Thus the techniques have of necessity had to
be relatively simple in application and to have used easily acquired
photography or imagery. Since in the main one is dealing with a country
notorious for its weather conditions, the type of remote sensing system
used has been restricted to air borne photographic systems with emphasis
on vertical black and white photography.
In order that such photography could be used in the fullest way for
research purposed, the instrumentation mentioned in the Introduction has,
during the years, been augmented with Old Delft Scanning stereoscopes,
Wild ST4 Stereoscope fitted with parallel guidance and 3x and 8x
binoculars, a Wild strip stereoscope, a sketch master and a Carl Zeiss
