The nominal descending equator crossing time is at 1000-1015, with a period of 99 minutes and repeat coverage of 16 days.īuilt by LMMS (Lockheed Martin Missiles and Space), the Landsat-7 spacecraft uses a very similar design to its predecessor, Landsat-6. Landsat-7 undergoes a sun-synchronous polar orbit at an altitude of 705 km with an inclination of 98.2°. The wide along-track coverage permits sufficient integration time for all cells in each scan sweep. This arrangement provides parallel coverage of 480 m along-track in one scan sweep (cross-track direction). The scanner contains two focal planes and detector line arrays oriented in the long-track direction. Data acquired using ETM+ has applications in land cover/change monitoring, agricultural forecasting, disaster response, urban planning, land and water resource management, and ecosystem monitoring.ĮTM+ images with a spatial resolution of 15 m for the PAN band, 30 m for VNIR/SWIR bands and 60 m for the TIR band, each covering a swath of 185 km. The addition of the PAN band, improved resolution and two 8-bit “gain” ranges in ETM+ have led to Landsat data progressing into use for global scale studies. ![]() ETM+ is a whiskbroom scanning radiometer capable of imaging in eight distinct bands including four visible and near-infrared (VNIR), two short wave infrared (SWIR), one thermal infrared (TIR) and one panchromatic (PAN) band. Landsat-7 features the Enhanced Thermal Mapper Plus (ETM+) developed by Raytheon SBRS (Santa Barbara Remote Sensing) which builds upon the Thermal Mapper (TM) onboard Landsat-4 & -5.

The ingredients were ready for cooking immediately, except for some minor things to enrich the experience. The lesson began with a simple explanation of the types of spices and cooking ingredients, and we started cooking. ![]() The price is very reasonable, as it only cost 8000 Sri Lankan rupees (equivalent to about 100 Saudi riyals) per person, and we ended up with more than 10 dishes also a desert, including a special recipe that we prepared in less than two hours! The cook is an elderly lady named Nandini, sweet and kind, who speaks English reasonably well, and the homeowner is with her. "Their service is excellent, and since the road to the place is rough, they pick you up at the end of the road with a tuk-tuk.
