Ongoing Projects

Applications of LiDAR Data for Inarajan Watershed Management

This research proposal focuses on applications of LiDAR data collected in early 2007 for Inarajan Watershed management. Raw LiDAR data will be used to obtain watershed characteristics for Inarajan Watershed. In this project, GIS and related technologies such as remote sensing and global positioning system (GPS) will be used to collect, digitize, organize, model and analyze data on watershed characteristics. GPS can be used for data ground-truthing, remote sensing can be used to collect data for hard-to-reach areas and to update GIS database, while GIS, enhanced by remote sensing and GPS capabilities, will be the core tool for this project. The overall objective of the project aims to obtain watershed characteristics from LiDAR data for Inarajan Watershed. (Funding source: U.S. Geological Survey)

 

Spatio-temporal Analysis of Groundwater Quality in Guam

This proposed research project is primarily focused on analysis of groundwater quality. The water quality data from 1996 to 2009, provided by Carmen Sian-Denton, Guam Waterworks Authority’s (GWA) Monitoring Laboratory Services Administrator, will be used to analyze the groundwater quality in space and time. Spatial interpolations, spatial statistics and GIS will be applied to conduct spatio-temporal analysis of groundwater quality based on individual wells, clustered wells, and wells within subbasins. A GIS tool for managing groundwater quality data will be established, and trends of groundwater quality will be analyzed. (Funding source: Guam Hydrologic Survey)
