proper forest management needs quantitative and precise estimates of forest stands characteristics. remotely sensed imageries, due to accurate and broad spatial information, has become a cost-effective tool in forest management. classification of forest attributes and generation of thematic maps are among the common applications of remote sensing. the objective of this study was to optimize the...

A key factor in the implementation of productive and sustainable cultivation procedures is the frequent and area-wide monitoring of cropland and grassland. In particular, attention is focused on assessing the actual status, identifying basic trends and mitigating major threats with respect to land-use intensity and its changes in agricultural and semi-natural areas. Here, multi-seasonal analyse...

the preparation of vegetation cover maps by used the land inventory and a traditional method has a lot of cost and time. but today, remote sensing is one of the main sources of data collection and information production for study and monitoring land resources, and was efficient tools for providing quickly and timely data and information needs for program planning in the natural resource filed. ...

Abstract: Placing a satellite or any other spacecraft in orbit is a risky and expensive process; years of research and a lot of money are transformed into equipments that will be beyond any possibility of maintenance in case something goes wrong. Therefore, space projects must be carried on as carefully as possible in order to guarantee that satellite equipments perform its mission properly. In...

GPS/IRS hybridization is a good candidate to fulfill demanding civil aviation requirements. When the integrity of the GPS measurements is ensured they may be used to calibrate inertial position and improve accuracy. This can be done in a tightly coupled manner by means of a Kalman filter. Calibrated IRS can ensure coasting while maintaining good short term accuracy and helps detect large GPS fa...

The major objective of this study was to develop site-specific spectral vegetation index-LAI relationship for two cotton varieties cultivated in the Central State Farm (CSF) Hisar, using multi-date radiometric and LAI measurements as well as digital data of LISSIII onboard Indian Remote Sensing Satellite (IRS). The field-level LAI was measured using LAI-2000 Plant Canopy Analyser and Aerosol op...

High-resolution satellite images (HRSI) at sub-5m footprint such as IKONOS, IRS-P5 (CartoSat-1) and SPOT-5 HRG/HRS images are becoming increasingly available to the earth observation community and their respective clients. HRSI is one of the main data sources for the Project of West China Topographic Mapping (WChTM) which has been approved by the State Council of China in year 2006. In western ...

Derivation of geophysical parameters from satellite measured brightness-temperature (TB) is an important aspect of satellite remote sensing. Primarily, this involves development of complex inversion algorithms and empirical relations comprising TB and in situ data for parameter retrieval and algorithm validation. In the present work, an Artificial Neural Network model has been attempted to simu...

The Frame synchronizer code for IRS satellites is a PN sequence of 127bits. In the satellite data format the frame sync code has to be detected reliably and efficiently. During real-time when the serial data from satellite is being frame synchronized at ground station, there is a need of perfect frame synchronization at the ground otherwise the whole reference is lost. The frame synchronization...

Pulicat Lake is one of the major wetlands in India. It is the second largest brackish water lagoon in India next to Chilika Lake in Orissa state. Pulicat Lake sits beside the Bay of Bengal so, the study on the mouth is vital. The investigations were carried out by using multi-temporal satellite imageries of IRS P6, LISS III data for four years viz., 2009, 2011, 2012 and 2013. Subsequent changes...
