Proportional Hazard Modeling and GIS

By integrating GIS with proportional hazard modeling, we are now beginning to see GIS increasing its analytical modeling repertoire for the sciences that leverage factors of spatial and time to better understand how emergence and evolution of given processes develops, even when uncertainty is persistent for areas of research.

Spatial Analysis

Changes in Cambodia from Sentinel-1A readings at 20 m resolution, acquired every 12 days from March 2015 to March 2016. Dark blue represents water surfaces, light blue to magenta represents agriculture (bare soil and cultivated fields), light to dark green represents forests, and white indicates settlements. In particular, the varying shades of magenta indicate rice sowing and transplanting between mid-September and the end of October. Source: contains modified Copernicus Sentinel data (2015–16)/sarmap/RIICE project/OpenStreetMap contributors (background map).Changes in Cambodia from Sentinel-1A readings at 20 m resolution, acquired every 12 days from March 2015 to March 2016.

Using Remote Sensing to Map Rice Paddy Drop in the Mekong Delta

Satellites including Europe’s Sentinel-1A can now track the rise and fall of different agricultural products around the world. The satellite’s imagery showed that rice production in the Mekong Delta has decreased in the past year.

Using Remote Sensing to Understand Cross Border Conflict

The American Association for the Advancement of Science (AAAS) has produced a manual entitled “Introduction to Remote Sensing of Cross Border Conflicts: A Guide for Analysts” as part of a project by its Geospatial Technology Project staff to understand the use of satellite imagery as a tool for “understanding border conflicts and possible conflict prevention.”
