"Geography is a subject that I have been wanting to study for a long time. Most of the work I did in the military had something to do with geography. The fields I am interested in are GIS and Remote Sensing. Especially I am interested in change detection in geospatial, such as modeling that can intuitively recognize changes in the AOI (Area of Interest) by effectively merging the information obtained from the imagery collecting system into legacy data."
