CSU LiDAR 1 participates in the 7th CREATE Congress

The CSU LiDAR 1 Project Team participated during the 7th Caraga Region Engineering, Architecture and Technology Educators (CREATE) Congress held last March 23, 2015 at the Robinson’s Place, Butuan City.

Engr. Lorie Cris Asube, Project Staff and CEIT Faculty Member, presented a background of the project to participants during the plenary sessions of the Congress in behalf of the Project Leader, Engr. Meriam M. Santillan.

The project team also showcased the project and its outputs during the the Congress by setting-up an exhibit booth. The booth was eagerly visited and appreciated by Congress participants who came from various State Universities and Colleges, Higher Education Institutions, key government agencies, and non-grovernment agencies within Caraga Region.

The CSU LiDAR 1 team explained major aspects of the project: its background, project areas, expected outputs, and its benefits to the Caraga Region communities.

The 7th CREATE Congress became a good venue for CSU LiDAR 1's information dissemination campaign.

The 7th CREATE Congress was held with the theme CREATE: Committed to a Resilient And Technologically-Empowered Society (or CREATE CREATES). It was aimed to provide Engineering, Architecture and Technology Educators updates in the topics of Disaster Risk Reduction thru the application of RS/GIS; to provide avenue for the students to showcase and present their projects and researches; and to provide students and faculty with the latest trend in Engineering, Architecture and Technology.

UPD Phil-LiDAR 1 DPPC visits CSU LiDAR 1

The Data Pre-Processing Component (DPPC) of the University of the Philippines-Diliman (UPD) Phil-LIDAR 1 project visited the CSU LiDAR 1 office last March 11-13, 2015. The visiting team was composed of Engr. Sarah Jane Samalburo, Chief Science Research Specialist; Engr. Gladys Mae Apat, Supervising Science Research Specialist; Engr. Harmond Santos, Senior Science Research Specialist; and Engr. Kechy Solidum, Senior Science Research Specialist.

Jojene R. Santillan (CSU LiDAR 1 CSRS), Engr. Presley Carl Oconer (DPT), and Engr. Jesiree Servianco (DPT).

The purpose of the visit was to address and discuss existing LiDAR data processing issues and concerns encountered by CSU LiDAR 1’s Data Processing Team (DPT). The visit was very important considering that all LiDAR data being processed by the DPT (i.e., preliminary Digital Terrain Models – DTMs, Digital Surface Models – DSMs) all came from UPD DPPC which they generate through pre-processing of raw LiDAR datasets. These preliminary DTMs and DSMs are being edited and mosaicked by the DPT to produce geometrically accurate, calibrated and validated DTMs and DSMs. These final outputs are then utilized by the DPR or extraction of features (buildings, roads, bridges), and by the Flood Modeling Team (FMT) for flood model development. The UPD Phil-LiDAR 1 DPPC Team also presented how they do the LiDAR data pre-processing: from data download from the LIDAR sensor, georeferencing, LiDAR classification, and generation of preliminary DTMs and DSMs.

During the visit, several issues and concerns were discussed that includes coverage of available LiDAR data, status and progress of LiDAR DTM and DSM editing and mosaicking, technical problems encountered during editing and mosaicking, and DTM and DSM quality checking.
