About the GIS Lab

The Loma Linda University Health Geoinformatics (LLUHGIS) Laboratory is a modern education/training and research facility fully equipped with professional Geographic Information Systems (GIS), Global Positioning Systems (GPS) and remote sensing technologies.​

The LLUHGIS lab is located in the Centennial Complex on the Loma Linda Campus. The lab provides students, faculty, and staff easy access to the extensive geo-technology resources available to all Loma Linda University Health schools and departments. The lab is integrated with the LLUH backbone/servers and benefit from 24/6 technical support personnel.

The spacious facility is equipped with two computer lab rooms, each with twenty seats in rooms 3110 (east lab) and 3102 (west GIS lab) separated by a support room, 3104. There is no contiguity to utilize the two labs as a 40-seat lab. The computer workstations are supported by peripherals such as a plotter, GPS devices, printers, and others.  Rooms 3102 and 3110 can be accessed with an LLU’s badge by authorized individuals; lab 3104 is reserved for GIS lab personnel only.

The lab manages the Environmental Systems Research Institute (Esri) GIS software site license and maintains, database management systems and other spatial analytic and visualization software packages. The lab also stores and manages a significant amount of spatial data, including demographic, population, environmental, satellite images, and aerial photographs. The 40 computers in the lab are a radical improvement over what we have been using for the past years.  One significant change that is particularly exciting is the capability of a gigabit networking between the desktop computers and our data servers.


Loma Linda University GIS students


By applying geotechnology principles to health practices, LLUGIS has brought an unprecedented level of scientific exploration to public health policy decision-making. Following are some of the GIS professional service applications LLUGIS has been or currently involved.

A deeper understanding of the associations of health-relevant behaviors in their full geographic environment can provide valuable insights to possible mechanisms and factors that can have altering effects, as well as enhance clinical practice and quality of care. As a result, LLUGIS has established a research agenda to expand the current understanding of how the environmental and socio-cultural context of a community interacts with individual behaviors and health outcomes.

Over the past several years, course offerings in health geoinformatics have proven to be an important factor in students’ education. Therefore, it is imperative that we continue to innovate through our curriculum to provide students with cutting-edge GIS technology to enable them to become competitive in the job market and more efficient industry leaders. Thus, the goal is to ensure that every School of Public Health student is exposed to GIS capabilities.
