چکیده
This paper presents preliminary research results on using semantic technologies to model Earth observation satellite data. The research goal is to enhance the data search functionalities that satellite data catalogues provide to researchers and practitioners. An ontology that captures characteristics of satellite data is introduced. How to utilize this ontology in assisting data search and how to integrate this ontology with the existing satellite data catalogue is presented. One strength of this work is that it closely targets the existing satellite data catalogues, as they are the major sources of the satellite data. Therefore, this work is expected to effectively improve the efficiency when scientists searching satellite data. Another strength of this work is its flexibility, compared with the limited and stable searchable metadata elements employed in the satellite data catalogues. Therefore, this work is expected to dramatically expand the user base for satellite data catalogues from scientists and researchers to non-professionals, and even to

Scheduling a constellation of agile earth observation satellites with preemption
In this paper, we consider a scheduling problem for a set of agile Earth observation satellites for scanning different parts of the Earth’s surface. We assume that preemption is allowed to prevent repetitive images and develop four different preemption policies. Scheduling is done for the imaging time window and transmission time domain to the Earth stations as well. The value of each picture ...
متن کاملReservoir water temperature modeling by geostatistical analysis of ASTER images (Case Study: Dez Dam, Iran)
Satellite data have been used for temperature modeling both in urban areas and water. This paperstudies viability of ASTER satellite images that provide high spatial and spectral resolution to model watersurface temperature, as a fundamental water quality parameter. This study is focused on Dez dam reservoirresiding in Khuzestan province, south west of Iran. After the image corrections required...
متن کاملAn efficient utilization of intermittent surface-satellite optical links by using mass storage device embedded in satellites
Recently, earth observation system by using satellite network have attracted much attention due to their wide coverage and disaster resistance. Although the system is useful for collecting various data, which have an affect on a natural disaster, ecology and so forth, earth observation satellite hardly send the collected observation data to the ground station. This is because that the earth obs...

The Advanced Land Observing Satellite (ALOS) was successfully launched on Jan. 24, 2006, from Tanegashima Space Center, Japan. The objectives of ALOS are [1]: (1) to provide maps for Japan and other countries including Asia-Pacific region (Cartography), (2) to perform regional observation for "sustainable development", harmonization between Earth environment and development (Regional Observatio...
متن کاملMonte Carlo Ray Tracing Based Non-Linear Mixture Model Of Mixed Pixels In Earth Observation Satellite Imagery Data
Monte Carlo based non-linear mixel (mixed pixel) model of visible to near infrared radiometer of earth observation satellite imagery is proposed. Through comparative studies with actual real earth observation satellite imagery data between conventional linear mixel model and the proposed non-linear mixel model, it is found that the proposed mixel model represents the pixels in concern much prec...
