Geospatial Data Processing

We provide solutions of various geographical information services, from geographical modeling linked with numerical simulations of fluid dynamics, river flood, inundation due to tsunami run-up/storm surge, through visualization of simulations, to the superposition of simulation images on background maps using GIS. In recent years, we extended our services to the drawing of refined geographical maps like river cross-section using laser profiler (LP) data, as well as to geographical modeling for analyses of landslide/inundation and so forth.
