Welcome to the Laboratory of Geographic Information and Spatial Analysis (LaGISA)

 

Geographic data refer to the recordings of measurements taken at certain places (or locations) and times on earth surface or near earth surfaces. They link place and time to physical/enviornmental/climate and social/economic/demographic/healthy-related attributes and are the basis for spatial information systems and spatial-related decision makings. With widespread use of remote sensing, global positioning system (GPS), and geographical information system (GIS) technologies in past several decades, a great deal of geographic data has been accumulated along with a wide range of spatial and temporal scales. The increasing amount of geographical data demands significant changes in the approach of integrating, analyzing and modeling these data for various applicants.

The LaGISA was established by Dr. DongMei Chen to develop a stimulating environment for research and training on geographic data collection, management, mapping, visualizion, analysis, and modeling. The core techniques in LaGISA include geographic information science, remote sensing, spatial analysis and enviornmental modeling. Our research goal is to develop the methods and technologies to understand spatial/temporal trends, patterns and structures in large spatial data sets, analyze and model dynamical changes and relationships in environment, ecology and health applications. In LaGISA we use traditional methods available in commercial packages, as well as develop new tools through programming and customization.

As a training and research facility for senior undergradaute, graduate students and researchers, LaGISA is equipped with state-of-art computing and server capability, as well as software on GIS, spatial analysis and image processing, includingArcGIS, ENVI, PCI, IMAGINE, MATLAB, IDRISI, eCognition and etc. In the past LaGISA has collaborated with companies, local health units, city departments, provincial and federal governmental agencies to address various issues in city and regional planning, disease spreading, land use/cover change, water quality, air pollution, climate changes and others. Students trained from LaGISA have been hired by private companies, governmental agencies and academical organizations.
