Quezon City, Ph — The Remote Sensing and Data Science: DATOS Help Desk (DATOS Project) spearheaded a week-long series of training sessions with the researchers of Sugar Regulatory Administration last 19-23 November 2018. The training focused on the use of high performance computing (HPC) and advanced remote sensing and GIS techniques for sugarcane mapping.

This technology transfer is a part of DOST-ASTI’s commitment in the Memorandum of Agreement with SRA which primarily includes, but not limited to, the provision of expert advice and recommendations pertaining to remote sensing and GIS technologies applications.  

Different accuracy assessment methods and measures were tackled during the sessions. Though the DATOS team only discussed five accuracy types (i.e, positional, thematic, attribute, thematic and geometric), the focus was the thematic accuracy measures used to define a map.

New accuracy measures were introduced such as F1-score, Recall, and Sensitivity that might potentially provide more meaning on the generated map.

The team also discussed the theory of radar remote sensingfrom image acquisition to image generation. The group identified key differences between optical and radar remote sensing to aid in the interpretation of images generated by Synthetic Aperture Radar (SAR) platforms.

DOST-ASTI personnel, particularly the researchers from DATOS, PEDRO, and CoARE teams continue to coordinate and collaborate with SRA in validating accuracy and acceptability of processed sugarcane maps and other output for distribution. In return, SRA commits to providing technical expertise and support in the area of sugarcane production activities and related sugarcane researches.

DATOS aims to produce outputs to support critical activities on disaster mitigation, analysis, and advice. DATOS utilizes data from both on-going and completed DOST-funded programs/ projects, and other private/ non-government organizations (open-source).
