Tsunami Satellite Sensor Data Catalogue (TSSDC)
The tragedy of Tsunami brought coordinated and concerted effort of numerous satellite sensor data providers (Table 1 below), from around the World, under one umbrella in making data available and accessible for free for the Tsunami related work. The data was made available on a near-real time basis for the entire Tsunami affected area. This in itself brought great challenge of organizing and disseminating the well catalogued data that is made easily accessible to Global Community. The Tsunami Satellite Sensor Data Catalogue (TSSDC) was a substantial effort of Remote Sensing and GIS unit (http://www.iwmidsp.org) of the International Water Management Institute (http://www.iwmi.org) in downloading, cataloguing (e.g., tile number, date of acquisition, and image quality- see please see attached spreadsheet), and pre-processing (e.g., mosaicked them into large blocks based on sensor type, organized them into pre- vs. post-tsunami) data from every available sensor and source (Table 1 below). IWMI started voluntary support to Sri Lankan government at Centre for National Operation (CNO) just after 26th December 2004 by providing 24 hours emergency disaster mapping support for 4 weeks to National and International decision makers to facilitate rapid response to the Tsunami disaster-one of the worst disasters in any one’s living memory. During that time IWMI in collaboration with MapAction, a UK based NGO, had setup an emergency GIS mapping protocol. This was handed over to the Sri Lankan survey department to continue further. All Tsunami response vector data and maps for Sri Lanka are available at http://www.iwmidsp.org/iwmi/info/tsunami.asp. The TSSDC is the continuation of this effort to support the global community in terms of satellite remote sensing before and after the Tsunami to help decision makers in relief and rehabilitation. The need for high resolution satellite sensor data in Tsunami relief and rehabilitation work in the region can not be over-emphasized. The IWMI’s TSSDC is a perfect catalogue and data warehouse for Tsunami related relief and rehabilitation work. However, there is an urgent need to develop a data sharing protocol, for disseminating this data to the agencies, organizations and individuals involved in Tsunami rehabilitation and reconstruction. In order to accomplish a wide dissemination of this data to the relevant partners, IWMI agreed to collaborate with the CGIAR-CSI (Consortium for Spatial Information), FAO, and other UN agencies. The CGIAR-CSI will host and develop an online data sharing platform specifically intended for coordination and information exchange for Tsunami related work. It is expected that users of this site will register, and be granted varying degrees of permission for accessing online data, dependent on their affiliation. As a result, we envisaged a system of permission levels, e.g. full access for UN agencies and govt. ministries, more limited access to proprietary imagery for individuals, etc., in accordance with the permissions we are granted for disseminating particular datasets. CGIAR-CSI would develop a web interface to provide this valuable data to host country governments, relief agencies and others involved in rehabilitation and reconstruction. We want to acknowledge all data providers (Table 1 below) and the great service provided by the disaster response unit, SAIC (Dr. Brenda K. Jones, disaster response coordinator) and USGS EROS (Dr. James Verdin, Head of the International Program). Indeed, it will be impossible to thank all those who contributed to this effort, so selflessly. We want to thank them for their support. The IWMI RS/GIS Unit team spent considerable amount of time in downloading, cataloguing, and processing TSSDC data. This is a thankless job. We hope the researchers and others using TSSDC data adequately acknowledge the great team who made this possible: Chandrashekkar Biradar, Aminul, Islam, Praveen Noojipady, Jagath Vithanage, Wasantha Kulawardhana, Venkateswarlu Dheeravath, Ranjith Alankara, and Sarath Gunasinghe. The TSSDC is now coordinated and made accessible through the CGIAR CSI (http:// csi.cgiar.org) For further information on the CGIAR-CSI, please contact Dr. Robert Zomer of IWMI and CSI. Kind regards,
List of Data Providers who Contributed to IWMI’s TSSDC Landsat, ASTER, Radarsat, and many others : USGS disaster response Lots of free imagery from Landsat ETM+ (30-m), ASTER (15-60 m), Radarsat (various), and other sensors. Keep visiting this site that is constantly updated. Free images. These are coordinated by USGS, NASA, and numerous other agencies. Free data download ftp link: Tsunami response and various links:
Global Change and Earth Observation: Michigan State University Landsat 30-m Image analysis. This site provides good science analysis of Landsat data and products thereof..
Extensive analysis of Tsunami using SPOT and IKONOS and numerous other data. Rapid response. Including mpeg movie animations. Fantastic site. The Centre for Remote Imaging, Sensing and Processing at the National University of Singapore provides some excellent SPOT and IKONOS imagery that are @ high resolution JPEG etc. Very useful for disaster assessment.
IKONOS 1 to 4 meter media images: IKONOS 1 to 4 m media Gallery: IKONOS 1 to 4 meter data from SpaceImaging:
All Global Satellites: A great source Links provided by Jean-Luc Bessis, CNES Programmes Direction, Risk management coordinator Board member, International Charter "Space and Major Disasters". These are some great sources of Tsunami data, analysis and rapid response.
Tsunami Response Map Viewer with rich sets of baseline data.
Source of all Tsunami data from Indian satellites. Resolution vary between 5 to 25 m.
Has a page that shows "before and after" events @ 0.61 to 4 m.
OrbView-3 1m panchromatic and 4 m multispectral imagery. Their web page indicates that they have increased their image download of the tsunami area.
Quality course resolution data
