We use crowdsourced GIS data from OpenStreetMap to help automate the mapping of land cover in Landsat satellite imagery. The OpenStreetMap data had limited area coverage, but was useful for building a model which could classify land cover in the other areas.

We developed a method for mapping residential areas using freely available satellite imagery. The resultant residential area map can be used for risk assessment (e.g. to estimate the population living in a flood-prone area). Our method can be applied for flood risk assessment in other watersheds in the future.

We analyzed the change in vegetated and urban (impervious) area in the Silang-Santa Rosa sub-watershed of the Philippines to assess the implications related to flood risk. Our main findings were: -The impervious area of sub-watershed increased by 54% (from 3,239 ha. to 4,988 ha.). -The vegetated area decreased by 21% (from 8,509 ha. to 6,760 ha)....

This dataset can be used by researchers to test different land use/land cover mapping methods using crowdsourced geographic data and Landsat satellite imagery. The study area is the Laguna de Bay area of the Philippines, and the satellite data is from 2014-2015. This dataset will also be available on the "UCI Machine Learning Repository" (https:/...

COP21 で採択されたパリ協定においては、世界全体の平均気温の上昇を2℃より⼗分下⽅に抑える世界共通の⽬標が設定され、我が国のみならず、世界全体での⼤幅削減が必要である。また、我が国においては、昨年10 ⽉に菅内閣総理⼤⾂が2050 年までにカーボンニュートラルを⽬指すことを宣⾔したほか、今年4 ⽉には2030 年度に温室効果ガス46%の削減、さらに50%の⾼みに向け挑戦する旨を宣⾔しており、脱炭素社会の構築が求められている。 2019 年6 ⽉に我が国が議⻑国となり開催された、G20 持続可能な成⻑のためのエネルギー転換と地球環境に関する関係閣僚会合では、イノベーションをテーマとする議論が⾏われ「軽井沢イノベーションアクションプラン」が採択された。こうしたG20 の成果を受けて...

We developed a fast method for land cover mapping using satellite imagery and crowdsourced geographic data (land use polygon data). The method is less time- and labor-intensive than traditional land cover mapping methods because the crowdsourced data substitutes for training data collected the traditional way (through field survey or visual image...
