The Centre for Remote Imaging, Sensing and Processing (CRISP) is a university-level research centre of the National University of Singapore (NUS), established in the early 1990s as a centre for the reception and processing of images from earth observation satellites.[1]
History and funding[edit]
CRISP had its beginnings in 1988, when military scientist Lui Pao Chuen proposed a joint laboratory between NUS and MINDEF to focus on signal processing and its applications. Under the leadership of physicist Lim Hock,[2] the Laboratory for Image and Signal Processing (LISP) was birthed in the Physics Department at the Kent Ridge campus, with support from the National Science and Technology Board (NSTB), the predecessor of A*STAR.
In 1992, founding director Lim Hock’s four-year projected budget of S$32 million was approved by NSTB,[3] and LISP was renamed as the Centre for Remote Imaging, Sensing and Processing (CRISP). In 1999, the current CRISP premises at block S17 of the Faculty of Science were completed, and CRISP administrative staff and the Data Processing Facility (DPF) moved in.
List of satellites[edit]
CRISP is currently receiving and processing data from the following satellites:[4]
- FENGYUN
- TERRA, AQUA and SUOMI-NPP
- WORLDVIEW-1 and WORLDVIEW-2
- CBERS 4
Quicklook images and location maps are provided together with textual information via an in-house catalogue-browse system.
Research[edit]
The current research foci of CRISP encompasses:[5]
Very high spatial resolution imagery[edit]
Research areas include:
- Mapping at large scales (1:5000 to 1:25,000) with high positional accuracies
- Detection and enumeration of trees in high resolution imagery of oil palm plantations
- Extraction of linear features in high resolution imagery
Digital elevation models and 3D modelling[edit]
Research areas include:
- Generating digital elevation models from high resolution optical and Synthetic Aperture Radar (SAR) data
Cloud-free mosaics[edit]
Research areas include:
- Cloud-free Mosaics of high resolution optical remote sensing images
Multiple polarization SAR[edit]
Research areas include:
- Land cover classification using multipolarization SAR
Hyperspectral Data[edit]
Research areas include:
- Applications of hyperspectral data from the EO-1 Hyperion sensor in land cover classification
- Retrieval of coastal water quality parameters from ocean colour and hyperspectral data
Environmental Monitoring[edit]
Research areas include:
- Derivation of environmental information from wide coverage satellite data with tens of spectral bands (such as MODIS, MERIS and GLI)
- Detection and mapping of land/forest fires
- Using MODIS for fire monitoring
- Red tide study using ocean colour data
- Oil pollution detection using satellite imagery
- Rapid environmental evaluation using remote sensing data
- Flood Monitoring
