STRUCTURE OF SAFE

Above Figure illustrates the structure of SAFE. It consists of three components: dataset creation, dataset distribution, and prototype activities. Each component includes information systems and human work flow.

1. Dataset creation

The component of dataset creation involves making satellite datasets for environmental monitoring. This component is driven by the data and applications creator. During the APRSAF-15, some agencies discussed their possible contributions (Chart 1).

Agency Country Data source
Asian Institute of Technology
(AIT)
Thailand MODIS
The Centre for Remote Imaging, Sensing and Processing
(CRISP)
Singapore MODIS
Australian Commonwealth Scientific and Industrial Research Organization
(CSIRO)

Japan Aerospace Exploration Agency
(JAXA)

The data and application creator may also consider utilizing the datasets created by other agencies or initiatives (Chart 2).

Dataset Creator
Global Satellite Mapping of Precipitation (GSMaP) GSMaP project
(JAXA / JST / Osaka Prefectural Univ.)
Global Forest Cover Map The ALOS Kyoto & Carbon Initiative
(JAXA)
Asian River basin datasets GEOSS / Asian Water Cycle Initiative [AWCI ]
Landsat Asia Archive GISTDA
Globcover ESA
Global Climate Archive Coordinated Enhanced Observing Period [CEOP]

In addition, as the advocator of SAFE, JAXA will contribute to SAFE by providing value-added datasets. Chart 3 describes JAXA’s planned value-added datasets.

Dataset Description
Water Cycle Database
*Ready for operation
JAXA prepares the dataset search and distribution website of Advanced Microwave Scanning Radiometer (AMSR-E) on NASA EOS Aqua and Precipitation Radar. The data are optimized for Asia, and user access and downloading are easy. In addition, JAXA will coordinate for customized near-real time distribution up to the prototype activity.
Precise Land-Use and Land-Cover Map derived by AVNIR-2
*In preparation
This dataset is applied to the decision-tree unsupervised classification method for multi-temporal AVNIR-2 images. The input AVNIR-2 images demonstrate the surface reflectance processed by atmospheric correction and ortho-rectification. The PALSAR data, digital elevation model (DEM), and seasonal changes of Normalized Difference Vegetation Index (NDVI) as the phenology of vegetation are also used as supplemental information. As a result, the accuracies of geometry and radiometry are improved.
MODIS PAR Database
*In preparation
Photosynthetically available radiation is a physical quantity that affects vegetation growth and the amount of carbon sequestration.
