  Detecting changes on the Earth, such as urban development, deforestation, or
natural disaster, is one of the research fields that is attracting a great deal
of attention. One promising tool to solve these problems is satellite imagery.
However, satellite images require huge amount of storage, therefore users are
required to set Area of Interests first, which was not suitable for detecting
potential areas for disaster or development. To tackle with this problem, we
develop the novel tool, namely GRASP EARTH, which is the simple change
detection application based on Google Earth Engine. GRASP EARTH allows us to
handle satellite imagery easily and it has used for disaster monitoring and
urban development monitoring.
