Satellite image analyses

Community health systems operating in remote areas require accurate information about where people live to efficiently provide services across large regions. We sought to determine whether a machine learning analyses of satellite imagery can be used to map remote communities to facilitate service delivery and planning.

Tra Vinh coast is approximately 65 km long and extends on NE-SW trend between two main river mouths of the Mekong River, Mekong River Delta. Based on satellite image analyses and field surveys, coastline change is identified since 1966 to present. The coastline change is mainly controlled by natural process showing alternation of accretive and erosive coasts from that accresion coast occurred widespread with rate of 5-10 m/yr, conversely, erossion coast occupied locally with rate of 5-8 m/yr during 1966 to 1989.

Discrimination and Interpretation of various land cover and land resources can be done using estimation of Normalized Difference Vegetation Index (NDVI) from multi spectral satellite data. This study has been attempted to analyse the changes is coconut growing areas of Coimbatore District in Tamil Nadu using multi temporal images of LISS III and Landsat 8 during 2012 and 2015 respectively Cross tabulation of the two temporal NDVI images were done and it could be observed that around 50 % of the total area remains in active plantation.

During the pre-monsoon months (March-May) in Nepal, severe thunder and hailstorms cause significant property and agricultural damage in addition to loss of life from lightening. Forecasting thunderstorm severity remains a challenge even in wealthy, developed countries that have modern meteorological data gathering infrastructure, such as Doppler Radar. This study attempts to isolate the specific and unique characteristics of a hailstorm that not only might explain its severity, but also suggest forecasting techniquees for future forecasting in Nepal.
