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.

To establish medium spatial and high temporal resolution Remote Sensing based Early Warning and Decision Support Systems to support Environmental Management in Mongolia

Conclusions

1. The active fire detection and burnt area mapping technologies

have been implementing and upgrading year by year

(NOAA&MODIS) and servicing to the related ministries,

agencies and other organizations are being operationalized.

2. Needed further cooperation with regional and neighboring

countries and involve in international programmes and projects.

Thank you for your attention!
