Attribute data represents the what or the properties of the geospatial information while the locational data describes the “where” aspect of the geospatial information. When representing entity-based information you can think […]

DEtte er overskriften In this course we will primarily be focusing on data produced by multispectral radiometers mounted on satellites measuring the spatial variations in the reflected/radiated EMR from the Earth’s surface and we will focus on how to use remote sensing data within the context of understanding the physical environment of the earths surface. The use of  Remote Sensing […]

remote sensing

Remote sensing is by USGS defined as “Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance from the targeted area”. In addition to this definition there are two key concepts we need to mention at this point namely: The sensors  or instrument i.e. the mechanism by […]
