27、stomer-specific presentations and transformations specific to image productThe scheme of image levels is given in Figure 1.Figure 1 Scheme of image levels5 GeneralA level 1 image is a two-dimensional matrix, representing information with regard to a physical space. In case of multi-frequency systems

28、, there is a matrix for each of the represented frequencies. This has to be considered in the meta data.Level 1 images shall be characterized by details on their geometrical and radiometrical content:a) geometrical information: Pixels are given in a sensor specific coordinate system;6 BS EN 17030:20

29、18EN 17030:2018 (E) Image is geo-referenced, i.e. transformation rules from sensor specific to a geo coordinate system are given; Pixels are given in an Earth-related coordinate system, i.e. a geo transformation is already applied and the image is resampled where necessary.b) radiometrical informati

30、on: Classification in calibrated or uncalibrated data. Uncalibrated data may content transformation rules for calibration within their meta data. Calibrated data are related to a reference at the sensor or to a reference on Earth.7BS EN 17030:2018This page deliberately left blankBSI is the national
