Research interests

What must be considered when one wants to understand forest is that any forest have its own history. Moreover, the forest does not exist alone, but it exists as a result of influences from its surrounding situation (both physically and institutionally). That means, we have to think of how the forest had been changing, also with its surrounding conditions, to know the forest.

But forest area is very large. (Of course agricultural area and even urban area are also large, but forest is even larger and usually exists in inaccessible place.) Most important thing is to go the forest by yourself, feel forest by your whole senses and make detailed field research of the area. But what you (or your group) can see is only limited points of the large forest area.

So, we always have to be aware of to which part of large forest area does our field research points belong, as well as their representativeness. If you want to know about whole forest and its surrounding area, but not so much in detail, we can use “remote sensing (RS)” technic to know as an area at once. To connect the detailed field research points and the information of the area obtained by RS, we can use GIS (Geographic Information System) and GNSS. These technologies are called “Geo-informatics” recently, all of them are dealing with geo-spatial information.

I hope I can keep studying how to use these spatial information processing technologies effectively as tools to help forest and human being live together long.

Study example

Forest environmental analysis using geo-informatics

  • Development of forest environmental assessment method using remote sensing and GIS
  • Monitoring forest environment using satellite remote sensing
  • GNSS utilization in forest area
  • Development of Asian tropical forest mensuration method applicable to REDD+
  • Utilization of LiDAR and aerial photographs for forest 3D structure reconstruction
  • Forest disturbance assessment in Siberian nature reserve area
