2. Satellite Management Application
Why?
Demand of digital satellite image products is growing
•Technological progress.
•Data appreciation as commodity.
•Impact of satellite data on global change and sustainable development.
In developing countries satellite products may be the most important
source of information if it not the only data available.

3. Satellite Management Application
Why?
Geological Surveys Context
• GS are playing new roles in the context of the development of NSDI,
environmental, global change and sustainable development studies.
• IT generated by land information agencies as GS are considered
essential to the development of countries, protection of lives, public
and private property, etc.
• GS data and expertise will have a strong impact in the society
• GS will play and important role as specialised product and data
providers.
Operational (corporate) and special application are required in order to
satisfy the public demand!!

4. GeoSatAR Project a Technological Transference Agreement
Between Japan and Argentina
• Transference of special processing equipment (hardware and software)
and training to Argentina (2001-2005)
• ASTER products supports the development of 1:250.000 and
1:100.000 national geological mapping program and specific mineral
resources and environmental studies.
• SEGEMAR actually have about 2000 level 1A ASTER images in
stock.
• There are ASTER products demand from public agencies, private
companies and other Latin American countries.

5. Development of ASTER Data Management Application
• Based on Arc-View 3.3 and Avenue programming
language (testbed system).
• Queries by time, data capture condition (cloud cover,
pointing angle, sun illumination geometry, etc.), and
geographic area.
• Support for relative geographic queries (cartographic
division, provincial territories, geographic features names,
etc.).
• Illustrate and promote the awareness about the role of
corporate applications at the GS

11. Results and Conclusions
• The ASTER Management Applications improve and accelerate the
image requesting process by providing specialised querying tools.
Image data can be searched by capture conditions and geographical
location (absolute and relative position).
• Relative geographical querying tool is considered and important
process because users usually express their image request in
geographical relative terms
• This prototype is the first step to develop a corporate and more
complex system.
• The development of corporate systems is justified by the increasing
demand of satellite image data and applications, the data appreciation
as commodity and their impact on global change and sustainable
development growing. In this scenario geo-scientific institutes should
assume roles as specialised data providers and NSDI and NSDI
contributors.
