Abstract
The standardization of the calibration of optical sensors in photogrammetry and remote sensing has been discussed for more than a decade. Projects of the German DGPF and the European EuroSDR led to the abstract International Technical Specification ISO/TS 19159-1:2014 “Calibration and validation of remote sensing imagery sensors and data – Part 1: Optical sensors”. <br><br> This article presents the first software interface for a read- and write-access to all metadata elements standardized in the ISO/TS 19159-1. This interface is based on an xml-<i>schema</i> that was automatically derived by ShapeChange from the UML-model of the Specification. The software interface serves two cases. First, the more than 300 standardized metadata elements are stored individually according to the xml-<i>schema</i>. Secondly, the camera manufacturers are using many administrative data that are not a part of the ISO/TS 19159-1. The new software interface provides a mechanism for input, storage, editing, and output of both types of data. Finally, an output channel towards a usual calibration protocol is provided. The interface is written in Java. <br><br> The article also addresses observations made when analysing the ISO/TS 19159-1 and compiles a list of proposals for maturing the document, i.e. for an updated version of the Specification.
Highlights
The origin of the ISO/TS 19159-1 “Calibration and validation of remote sensing imagery sensors and data – Part 1: Optical sensors” was a demand for a standardized sensor calibration procedure defined by the camera manufacturers
This demand was channelled by the European Spatial Data Research (EuroSDR) and other organizations
Photogrammetry and remote sensing belong to the world of geographic information (KRESSE & FADAIE 2004)
Summary
The origin of the ISO/TS 19159-1 “Calibration and validation of remote sensing imagery sensors and data – Part 1: Optical sensors” was a demand for a standardized sensor calibration procedure defined by the camera manufacturers. This demand was channelled by the European Spatial Data Research (EuroSDR) and other organizations. The ISO Technical Specification was the final conclusion of this development. Within TC 211 the development was associated to WG (Working Group) 6 “Imagery” (ISO/TC 211 2016). In the case of the calibration of optical sensors the European based original work covered the vast majority of the requirements of the Technical Specification.
