NGIC project
Dutch Government funded and the Mongolian
Ministry of Nature and Environment implemented
the program National Geoinformation center for
Natural Resources Management (NGIC)commenced in
December 2006 aims at macro level environmental
decision and policy making. The project has 4
components.
Component 3, NGIC project
To establish medium spatial and high temporal
resolution Remote Sensing based Early Warning and
Decision Support Systems to support
Environmental Management in Mongolia

Needs of the MODIS data

• For detection, monitoring, mapping and assessment
  of various Natural disasters (drought, fire,
  dzud, snow and dust storms, flood etc) is needed
  higher spatial resolution satellite data
• For this purposes NOAA/AVHRR data have been
  used over 20 years.
• 2. For permanent monitoring of Natural
  resources (forest, surface water, pasture etc.)
  and their changes not sufficient maps.
• The thematic maps of Forest, Surface water and
  Pasture/Fodder resources of Mongolia were
  produced long time ago

Why the MODIS?

MODIS and HRPT receivers, eOsphere, UK

• VxEos Ground Station is designed to receive and
  process
• the X-band Direct Broadcast transmissions from
  the EOS Aqua and Terra satellites (720 MHz)
• the L-band High Resolution Picture Transmission
  from the NOAA POES and Chinese FengYun 1
  satellites (137 MHz)
• VxEos Ground Station includes
• dual L- and X-band tracking antenna (X-band
  feed, LNA and down-converter, offset L-band feed
  and down-converter, reflector and tracking X/Y
  pedestal),
• GPS,
• cross-site cabling,
• MODIS Receiver,
• HRPT Receiver,
• synchronous serial interface cards
• 3 high specification Linux or Microsoft Windows
  based PC Workstations.

Conclusions

• MODIS data is very important for Mongolian NRM
  and Natural Disaster monitoring
• We need to prepare to receive, process and use
  data from next generation of TERRA and AQUA
  satellites with MODIS sensor
