The Earth and Planetary Image Facility (EPIF) is an interdisciplinary research facility hosting students with backgrounds in several academic disciplines including Geography, Electro-optics, Geology, Electrical Engineering, Computer Sciences, and Agriculture. The facility is located in the Department of Geography and Environmental Development in the main campus of BGU. The facility is a NASA Regional Planetary Image Facility with an active archive of maps and remotely sensed images from the Solar System. These facilities maintain photographic and digital data as well as mission documentation and cartographic data. Each facility's general holding contains images and maps of planets and their satellites taken by solar system exploration spacecraft.
The facility is well equipped and operates under several memorandums of agreement and contains Image processing hardware and software packages. Suite of applications software provides state-of-the-art capabilities for image processing, mapping, modeling, statistical analysis, and visualization. The work is done on Windows XP 32 bit operation system (Intel multi core processors system) and also on Linux ubuntu 64 bit operation system
(Intel multi core processors system). The lab is fully equipped with licenses of ERDAS IMAGINE,IDL ENVI PCI and Arc/GIS and eCognition) a list of the main software. In addition to a the computer software a Field equipment is also in use , it operate as mobile laboratories. |

An HRPT receiving Station which allows us to receive real-time AVHRR data from the NOAA-12 and 14, 15, 16 and 17 satellites. In addition, we are able to receive SeaWiFS data from Orbview-2, and FY1C,D images. The receiving station is fully equipped with Linux MEOS receiving station and a Tracking computer. |
Where is the Sun's current position on the Earth right now ?

Earth rotates about its polar axis as it revolves around the Sun. Earth's polar axis is tilted 23.5° to the orbital plane (ecliptic plane). Combinations of rotation, revolution, and tilt of the polar axis result in differential illumination and changing illumination patterns on Earth. These changing patterns of illumination result in differential heating of Earth's surface that, in turn, creates seasonal climatic and weather patterns. In the above, there is a high quality virtual map of the Earth. It shows which areas on the earth are illuminated by the Sun. The bright part of those regions indicate where they are in sunlight and the shadow part of those regions show where they are in darkness. The map projecting here is the Mercator projection.
