GINA is a mechanism within the University of Alaska (UA) for sharing data and technical capacity among Alaskan, Arctic, and world communities.
Established in 2001 as an initiative of UA’s President, GINA promotes collaboration at the local, state, and federal levels by increasing community-wide participation in the discovery and use of geospatial data. GINA’s products and services greatly expand the range of available analysis capabilities in order to better address research and management requirements.

Exciting nighttime visible images are now routinely retrieved and processed by GINA from the VIIRS sensor aboard the SNPP polar satellite. The VIIRS sensor has a Day Night Band (DNB) that allows detection of visible light at ‘night’. The DNB is highly sensitive in the visible range so that faint light sources such as moonlight, the Aurora, and city lights can illuminate clouds. Although its primary purpose is for helping the Alaska National Weather Service to track clouds, the light from an active Aurora can often “steal the spotlight”, so to speak. The images below were produced by combining DNB and Infrared channels from the VIIRS sensor into a color composite.
GINA receives numerous geospatial data sets, many in real time. Information is then rapidly processed and managed for use by scientiﬁc researchers, state and federal agencies, and the general public.
GINA is involved with many Alaskan, Arctic and International projects. Our goal is to increase community-wide participation in the discovery and sharing of geospatial data.
GINA teams with partner institutions and agencies to create information products and services that are used in a variety of projects to better display and understand spatial information.
