Free Data from Indian Resourcesat-2 Satellite via INPE

1

In December 2014, The National Institute for Space Research of Brazil (Instituto Nacional de Pesquisas Espaciais, INPE) announced the distribution of images deriving from the Indian Resourcesat-2 satellite. The images are received and collected at the ground station in Cuiabá, capital of the federal state of Mato Grosso, which is run by INPE. The images can be ordered for free at http://www.dgi.inpe.br/CDSR/ , only registration is required.

Resourcesat-2 is an orbiting Indian Earth Observation satellite and was launched in 2011 as a follow-on mission to the Indian Resourcesat-1 satellite increasing the observation timeliness (repetivity) in tandem with ResourceSat-1.  It carries three imaging sensors LISS-3 (Linear Imaging Self Scanning Sensor), LISS-4 and AWiFS (Advanced Wide Field Sensor). While the resolution diminishes from 5,8m (LISS-4) and 23,5m (LISS-3) to 56m (AWiFS), the swath enhances from 70km and 141km to 740km respectively. All sensors record in the green, red and near infrared bands, whereas the latter two sensors also record in the short wave infrared spectrum. The ResourceSat data find their application in several areas like agricultural crop discrimination and monitoring, crop acreage/yield estimation, precision farming, water resources, forest mapping, rural infrastructure development, disaster management etc.

INPE also distributes satellite images from the CBERS missions (China and Brazil), LANDSAT missions and Resourcesat-1. Hence, the Brazilian Institute for Space Research constitutes one of the most complete remote sensing catalogues in the world with images starting in 1973 right after the launch of LANDSAT-1.

I ever since was passionate about topography and started my professional life on a local scale by doing landscape design. With the European Master in Geospatial Technologies I continue on a larger scale and find myself highly comfortable with this complete outsight on what surrounds us here and there. My special attention goes to the topic of remote sensing, which enables to find answers to a series of problems of environment and planning. For me, the geo-world holds a high potential to learn and create life. An awesome 'g'!
