Abstract

<p>現象を空間的に拡張して想像する「地理的想像」を喚起し,地理的思考を促すことは,地理学のアウトリーチにおいて必要なアプローチのひとつである.本研究では,特に3次元地理空間情報を用いた空間的現象の可視化の手法を,縄文時代の集落生態系を対象とした古景観の復原に適用し,その効果的な活用について検討する.まず,小型無人航空機を用いた現景観の3次元空間情報を取得し,古景観の復原のためのデータ解析を行う.次に,オンラインシステムを用いた古景観の3次元的な表示と,博物館における展示としての提供を行い,その効果を検証する.ここで,地理学,考古学,第四紀学的な研究成果の統合だけでなく,芸術分野における表現手法との融合的表現を試みることにより,さまざまな閲覧者の時空間的な地理的想像を補うかたちで,復原された古景観の直感的理解を促す効果が示された.これは,地理的思考の普及にも発展的に貢献できることが期待される.</p>

<p>The encouragement of geographical thinking by inspiring "geographical imagination," i.e., an expanded vision of spatial phenomena, can be a useful approach for the outreach of geography. We developed a method to visualize spatial phenomena using three-dimensional (3D) geospatial information to reconstruct the palaeolandscape including the settlement ecosystem in the Jomon period and examined its effectiveness. Specifically, we first acquired 3D geospatial information on the present landscape using a small unmanned aerial vehicle and performed data analysis for reconstruction of the palaeolandscape. Then different visualization methods and their effectiveness were examined, including an online system of 3D visualization of the palaeolandscape and an exhibition at a cultural museum. For this, we performed trials not only of the integration of research outputs in geography, archaeology, and Quaternary research but also of the integrated expressions of artists. We found that these integrated approaches are effective in promoting an intuitive understanding of palaeolandscapes by supporting the spatiotemporal geographical imagination of various people. We expect that the further development of these methods will contribute to the dissemination of geographical imagination and thinking for the outreach of geography.</p>
