For those not on the map: GIS and the "final milestone" of support

When a disaster strikes, one of the most serious challenges is quickly identifying "who and where relief is not reaching." People who are "hard to reach" - such as the elderly, people with disabilities, foreigners, people living alone, and residents of mountainous or depopulated areas - often become invisible on maps, especially during a disaster.
GIS (geographic information systems) are a powerful tool for visualizing these "invisible" entities. By overlaying information such as evacuation shelter locations, population distribution, facilities for people with special needs, and road disruptions, it is possible to spatially identify "areas where relief is likely to be unavailable." However, in reality, this power is often hindered by delays in data updates, complex operations, and information fragmentation between departments.
This is why a GIS that can be fully utilized on the ground is crucial. A lightweight GIS like GISBox is easy to use, even without specialized knowledge, and its strengths lie in its ability to quickly update and share maps, even during a disaster. Damage reports and relief status can be instantly visualized as tiled maps, allowing all stakeholders to make decisions while viewing the same map. This is extremely important in shortening the time from information to action.
Ultimately, whether GIS can identify "hard-to-reach people" depends not on the sophistication of the technology, but on how closely it is connected to the field. Tools like GISBox can be said to move GIS from being reserved for experts to becoming a public infrastructure that saves lives.
