| Spatial Information on natural
and man made features of the earth's surface and their condition and change over
time is now recognized as critical for sustainable use and to remain in technology
driven competitive environment. Remote sensing has matured as an information technology
that provides a wide variety of spatial information in easily accessibility forms.
Images and associated information can be obtained from building and mine sites
to natural resources at national and global scales at time scales of hours and
days to years and decades. Monitoring of Earth involves acquisition of information
gathered without physical contact using sensors ranging from cameras to radar
to multi-spectral scanners mounted on satellites, aircraft and tripods. Analysis
involves a whole array of computer-based techniques to extract information for
decision support models used by managers and decision-makers. Management involves
recognizing the impact that spatial variability has on the enterprise and using
spatial measurements to devise solutions. 2. The current
generations of space borne optical images are either panchromatic or multispectral
providing just a few spectral bands and limited resolving power. Hyperspectral
images typically collect data in contiguous narrow bands (up to several hundred
bands) in the electromagnetic spectrum. They produce vast quantities of data because
of the number of bands simultaneously imaged. Present day state-of-the-art digital
image processing hardware and software can provide the image analyst the opportunity
to use multispectral imagery (MSI) and, in the future, hyper-spectral imagery
(HSI) for evaluating and monitoring terrain and target features. For example,
just as agriculture professionals now know to purchase three specific bands of
Landsat multispectral data instead of all seven so too will precision farming
experts choose solutions-oriented products derived from the hyperspectral data
set. Here, the advanced algorithms in some image processing packages assist them
in handling large data files. For instance, Research Systems has included Principal
Component Analysis and Minimum Noise Fraction routines in ENVI to reduce data
file sizes. A spaceborne hyperspectral sensor will be an
enabling tool used to monitor both static and dynamic targets at high spectral
and spatial resolution with greater accuracy and capability of developing unique
image products. Typically, the analysis of a hyperspectral scene involves the
decomposition of each pixel in the image into its constituents, where these are
represented by spectra of relatively pure material, which are themselves extracted
from the scene. The identity of these constituents is determined by comparison
with 'library' spectra of known materials measured in the field or in the laboratory.
All objects reflect, absorb, or emit electromagnetic radiation based on their
composition. A hyperspectral sensor, using reflected solar radiation (0.4 micrometers
- 2.5 micrometers wavelength range), captures the unique spectra, or 'spectral
signature', of an object, which can then be used to identify and quantify the
material(s) of which it is composed. During the past few
years several imaging spectrometer systems are customized for various applications
including algorithms for data processing, for example the Thermal Infrared Imaging
Spectrometer (TIRIS), the Intelligent Missile Seeker (IMS) and the applications
to lithological mapping, geobotanical mapping, development of algorithms and related
information products in exploration geology, environmental monitoring and assessment,
agriculture (Crop Health Monitoring), wetlands, manufacturing (Advanced Manufacturing
Technology), medical photodiagnosis imaging (Small Target Detection & Search
and Rescue Operations), camouflage detection, land mine detection, counterfeit
currency and cannibas detection, emergency response & plume tracking, battle
field monitoring of CB agents, detection of illicit drug manufacturing by products,
etc. The chemical & biological defenses are among the current military applications.
A military hyperspectral user who can "see deep" through the Earth's
atmosphere and accurately locate and identify objects of interest on the ground
in real time, will have a decided advantage on the modern battle space. For each
application area, hyperspectral products are identified, the potential benefits
of hyperspectral data are outlined and potential user groups are indicated. Within
each of these application areas, extensive field campaigns, including data acquisition
and associated ground reference for the validation and evaluation of algorithms
and information products, have occurred. The laboratory and field spectral measurements
(reflectance, emittance, and luminescence) of different natural resources and
man-made materials are to be generated as hard copy and soft copy. For
this capability and above said applications to be exploitable, it is essential
to develop hyperspectral technology with well-populated spectral library and is
to be accessible in a user-friendly way by the user of this technology. In India,
Hyper spectral signature studies and database systems are currently inadequate
and need to be developed further. Thus, from sensor to desktop, NRDMS-DST invite
you to join in presenting the latest technologies and developments in acquisition
and applications in remote sensing, GIS and GPS with minimal human intervention.
So that, data users and value-added providers will have the opportunity to share
their experiences using these advanced and exciting new technologies to optimize
projects, analyze and solve problems, and explore new applications and technology
improvements. So, current advances including new hyperspectral
sensors, spectral signature studies to different above said applications, developing
algorithms, object oriented image analysis to different application in the spatial
information technology are the timely event. This sub-programme of NRDMS, DST
will draw together experts and users involved in the monitoring of earth to management
under the spatial variability. -
