Senior Research Manager
Research Topics & Areas of Expertise
Geographic Information Systems (GIS), Remote Sensing, Spatial Modeling, and Data Mining for urban and environmental analysis and planning. Some of my recent research has focused on mapping urban land cover (green space, impervious surfaces, etc.) and monitoring forest health using fine resolution satellite imagery.

This study uses a spatially-explicit land-use/land-cover (LULC) modeling approach to model and map the future (2016–2030) LULC of the area surrounding the Laguna de Bay of Philippines under three different scenarios: ‘business-as-usual’, ‘compact development’, and ‘high sprawl’ scenarios. The Laguna de Bay is the largest lake in the Philippines and...

Land cover change (LCC) can have a significant impact on human and environmental well-being. LCC maps derived from historical remote sensing (RS) images are often used to evaluate the impacts of past LC changes and to construct models to predict future LC changes. Free moderate spatial resolution (~30 m) optical and synthetic aperture radar (SAR)...
Commissioned Report
REDD+の効果的な実施に向けた具体的な方策を示すため、REDD+の国際的な制度の動向等について多角的に調査・分析を行い、得られた結果について体系的に整理した。１－１ではUNFCCCを中心とした国際的な議論の動向について取りまとめた。１－２では、既存のクレジット制度である京都メカニズムの共同実施に注目した。１－３では、現在進んでいるREDD+に係る資金拠出に係る取組状況として、緑の気候基金、世界銀行の森林炭素パートナーシップ基金、The REDD+ Early Movers Programについて調査した。１－４では、REDD+に関する政策的な検討や各国の緩和対策の中での位置付けとREDD+活動の実施状況を、JCMパートナー国5カ国（インドネシア、ベトナム、カンボジア、ラオス、コスタリカ...
Fact Sheet
Three land-use scenarios (current: 2014 LU-Ls8, future: 2025 LU-Pm, and future: 2025 LU-Pop) were generated and analyzed for flood modelling. Event-based precipitation with 10 year rain return period classification and high resolution digital terrain model from LiDAR data5were used to generate detailed flood simulation. Findings from this study...
Fact Sheet
Three land-use scenarios (current: 2014 LU-Ls8, future: 2025 LU-Pm, and future: 2025 LU-Pop) were generated and analyzed for hydrologic modelling. The Global Climate Model: MRI-AGC M3.2S5containing 1979-2003 and 2075-2099 daily precipitation data was used to model the outflow in the subwatershedunder the three different land-use scenarios. Outflow...
Conference Paper
The Silang-Sta. Rosa subwatershed has undergone massive land use changes in the past two decades, brought about by rapid urbanisation and industrialisation. Since it is ideally strategically located for economic development, further conversion of forest and agricultural land for industrial, residential and commercial activities is planned in the...
Conference Paper
In this study, we assessed the relationship between land cover change and changes in water quality in the Laguna de Bay area of the Philippines. Land cover changes occurring between 2007 and 2015 were mapped using a combination of optical (Landsat-7/-8) and synthetic aperture radar (ALOS Palsar-1/-2) satellite imagery, and time-series water quality...
Data or Tool
This dataset contains supplementary material for the journal paper by Johnson et al. (2017). In the paper, OpenStreetMap crowdsourced data was used in combination with different types of satellite imagery to identify and map land cover changes in the Laguna de Bay area of the Philippines. The dataset provides the training data (derived from the...

In The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
Developing countries must submit forest reference emission levels (FRELs) to the UNFCCC to receive incentives for REDD+ activities (e.g. reducing emissions from deforestation/forest degradation, sustainable management of forests, forest carbon stock conservation/enhancement). These FRELs are generated based on historical CO2 emissions in the land...
Peer-reviewed Article
In Journal of Applied Remote Sensing
Multiresolution segmentation and rule-based classification techniques are used to classify objects from very high-resolution satellite images of urban areas. The major contribution of this research is the development of rule sets and the identification of major features for satellite image classification where the rule sets are transferable and the...
