Wildfire risk map nrsc2GeoMedeelelThis document describes a study that used remote sensing and spatial multi-criteria analysis to create a wildfire risk map of eastern Mongolia. Eleven factors related to environment, climate, fire history and socioeconomics were used as inputs and assigned weights. These included land cover, slope, temperature, rainfall, fire frequency and distance to roads. The factors were analyzed spatially to produce a map dividing the study area into five risk categories. The map was validated against historical burn areas with 62% accuracy. The final risk map is intended to help fire prevention planning and resource allocation.

It supports over 140 raster and vector data formats and has tools for data translation and processing. Key GDAL utilities include gdalinfo for reporting metadata, gdal_translate for format conversion, gdalwarp for image warping and projection changes, and gdal_merge for mosaicking multiple rasters. GDAL is open source and works across many operating systems.
2b intro num-cube_sat_v3GeoMedeelelThe document outlines the BIRDS (Joint Global Multi-Nation Birds) project, which aims to build and launch a constellation of 1U CubeSats from five countries including Mongolia and Japan. The project will provide hands-on engineering experience for students and help non-space faring countries enter the space field. It details the satellite design, integration and testing process, ground station setup, operations plan and timeline, with a total cost of around $100,000 USD per satellite.
Amgaa 201703150GeoMedeelelThis document analyzes dust weather categorization in Mongolia using satellite data from 2000-2013. Ground-based meteorological data from 113 stations is compared to satellite-retrieved aerosol optical depth to categorize dust haze, blowing dust, and dust storms. Dust phenomenon types are categorized based on the correlation between aerosol optical depth and horizontal visibility. The study finds a good exponential relationship between aerosol optical depth and visibility in April, allowing dust weather to be categorized from satellite data with spatial frequencies consistent with ground reports.
Presentation 20220316 nandiaGeoMedeelelThis document outlines a study to estimate above-ground biomass and carbon stock in boreal forests in Mongolia using satellite data and machine learning. Boreal forests cover about 9.2% of Mongolia but have been declining in recent decades. The study aims to develop a suitable machine learning model to map forest biomass and carbon stock. Random forest was the best performing model with an R2 of 0.24 and RMSE of 33 Mg/ha. Important input features included shortwave infrared band 1, green leaf index, and radar polarization data. The predicted forest biomass ranged from 32.5-122.5 Mg/ha and carbon stock ranged from 16.5-62.5 Mg C/ha. Some reference
Drone 20201216GeoMedeelelThe document outlines a study that uses multispectral drones and ground sampling to collect vegetation data from pasture sites over three sampling periods in June, July, and August. Various vegetation indices will be calculated from the drone and ground spectrometer data to analyze changes in biomass, chlorophyll content, and other vegetation metrics over time. A total of 285 sample points will be collected and various biophysical parameters will be measured at each point to analyze temporal changes in pasture sites.
