The Centre for Remote Imaging, Sensing and Processing (CRISP) is a research centre of the National Univeristy of Singapore established with funding from the National Science and Technology Board of Singapore.

CRISP's mission is to develop an advanced capability in remote sensing to meet the scientific, operational and business requirements of the region.

CRISP operates a satellite ground station to acquire data from remote sensing satellites, and processes the archived data to standard or value-added products for distribution. CRISP is ready to provide special products custom processed to users' requirements, or training/consultation services in the field of remote sensing.

CRISP undertakes research in optical and microwave remote sensing technology and applications. The current research interest areas are: ocean and coastal studies, tropical vegetation studies, and remote sensing data processing techniques.

### Remote Sensing Ground Station

CRISP's remote sensing satellite ground station is one of the first multi-mission ground stations built around the open system concept, with a high level of flexibility to accommodate future satellite missions. With a high gain tracking antenna with a 13-m diameter disc, it is able to acquire images of the earth's surface within a radius of about 3000km (for satellites orbiting at heights of about 800km), covering the following countries:

Brunei
Indonesia (except Irian Jaya)
Kampuchea
Laos
Malaysia
Myanmar
Philippines
Singapore
Sri Lanka
Thailand
Vietnam
China (Southern regions)

CRISP has been actively acquiring remote sensing data from SPOT since September 1995, and has by now (July 1997) more than 70,000 scenes of SPOT images in its archive. CRISP participated in the tandem operation of ERS-1/2 over the Southeast Asian region in early 1996, and has since arquired more than 9,000 scenes of ERS images. Reception of RADARSAT data began in May 1997. By now about 550 passes of RADARSAT images of various modes have been archived.

Users of remote sensing data can search the complete data catalogue of CRISP through internet by visiting CRISP's World Wide Web home page (http://www.crisp.nus.edu.sg). Quick look images and location maps are provided together with textual information throught the WWW catalog-browse system.

### Remote Sensing Products and Services

CRISP supplies standard and value-added products such as SPOT: 1A, 1B, 2A, 2B, Pan+XS, SPOTView in SPOT CAP format. ERS: RAW, FDC, SLC, PRI in ESA CEOS format. RADARSAT: RAW, SLC, SGF, SGC, SSG, SCN, SCW in RADARSAT CEOS format.

Data can also be delivered in TIFF or other standard formats which are ready for assimilation by GIS systems. The following media are available: CD-ROM, Exabyte (8mm), Quarter Inch Cartridge (QIC), CCT, 4mm DAT (unix tar format only).

CRISP is able to supply special products such as large area mosaics of ERS or RADARSAT images, multiple-scene mosaics of SPOT images, DEM generated from SPOT stereo pairs, RADARSAT radargrammetric pairs, and ERS interferograms.

CRISP is prepared to provide training or consultation services in the fields of remote sensing technology or applications. CRISP welcome proposals from interested organisations to jointly develop applications of remote sensing data.

### Research

CRISP's current research areas are ocean and coastal studies, tropical vegetation studies, and remote sensing data processing techniques. The on-going projects include:

Ocean and Coastal Studies
