Since 2015, Yvan has been immersed in projects and research on the field of surveying and mapping that, to a certain degree, have had signficant socio-economic impact for the country. In 2015, he started off by processing IFSAR data to derive susceptibility and DEM of various Philippine provinces through the GMMA-READY Project under PHIVOLCS. In 2016, he prepared hazard and risk maps incorporated in SQL databases to be used in Rapid Earthquake Damage Assessment System (REDAS) software, still under PHIVOLCS. In 2017,under the Flood Study of the San Juan River and Tributaries between the Quezon City Government and the University of the Philippines, Yvan led and managed the survey team to implement hydrography, bathymetry and project control surveys, and incorporated acquired field data onto LiDAR DSM using GIS for flood simulations and analysis. Also in early 2017, he co-authored A Study on the Use of Unmanned Aerial Systems (UAS) in the Conduct of Land Surveying: A Research Project in Support of Technology for Property Rights, which was cited by the DENR - Land Management Bureau for its policy on the use of drones for land surveying. In 2018, under the Land Sector Modernization Research Program, Yvan was involved with the Unified Projection System for Cadastral Data, which aimed to harmonize the three existing cadastral coordinate system of the country. Lastly, this year, he focused his efforts in the study Evaluation and Assessment on the Effects of Shifting the Existing Cadastre to Geocentric Datum under the Research and Development in Support of the PGRS Modernization of NAMRIA, which aimed to analyze the feasibility and implications of migrating to ITRF on cadastral data. With his experiences, and with the opportunity presented by the 15th South East Asia Survey Congress 2019, he aspires to broaden his knowledge and uplift the young surveyors in the South-East Asian region through the ASEAN Federation of Land Surveying and Geomatics (AFLAG).
