REDIAM. WMS Annual composition of night images of Andalusia generated from images from DMSP satellites, captured by the OLS sensor. Year 2008

Description

Node of the Andalusian Environmental Information Network. Regional Government of Andalusia. Annual compositions of stable and cloud-free lights, formed from all the daily night images available during the year 2008 of the satellites -Defense Meteorologycal Satellite Program- (DMSP) taken by the sensor -Operational Linescan System- (OLS). The composite excludes images that are illuminated by the sun or with glare, those that are illuminated by the moon and those that are illuminated by the aurora. It is an orthorectified night visual product that gives a fairly complete idea of the lighting levels to which the inhabited areas are subjected. The images have spatial resolution of 700 m resampled at 100m and cover the territorial scope of Andalusia. In cases where more than one satellite collects data during this year, there are compounds from each satellite. Node of the Andalusian Environmental Information Network. Regional Government of Andalusia. Integrated in the Spatial Data Infrastructure of Andalusia, following the guidelines of the Cartographic System of Andalusia. NOTE: The OLS sensor has no on-board calibration, and gain settings are not recorded in image capture. Therefore, although the annual cloud-free compounds are generated using the same algorithms and with precise selection criteria of the images that make it up, the ND value of the pixels is not strictly comparable from one year to the next.
