What is ISO 19115-2 - Extensions for acquisition and processing about?
ISO 19115-2 defines the schema required for an enhanced description of the acquisition and processing of geographic information, including imagery. Included are the properties of measuring systems and the numerical methods and computational procedures used to derive geographic information from the data acquired by them.
ISO 19115-2 provides the XML encoding for acquisition and processing metadata thereby extending the XML schemas defined in ISO/TS 191153.
Who is ISO 19115-2 - Extensions for acquisition and processing for?
ISO 19115-2 on Geographic Information is useful for:
- XML developer companies
- Geographic information centers
- Geospatial department
Why should you use ISO 19115-2- Extensions for acquisition and processing?
ISO 19115-2 helps you to provide guidelines on metadata for imagery and gridded data as they are important information sources and products used within a geospatial environment by geographic information systems.
The production of all geographical information, including imagery and gridded data, follows one or more process chains that begins with remote sensing data, scanned maps, field data collection or other sensing methods and ends with the creation of the end data products. The production process needs to be documented to maintain quality control over the end products. In addition, metadata about the geometry of the measuring process and the properties of the measuring equipment need to be retained with the raw data to support the production process.
The object of ISO 19115-2 is to provide the additional structure needed to describe the acquisition and processing of geographic information from all sources to improve the collection and presentation of data.
What’s changed since the last update?
BS EN ISO 19115-2:2019 supersedes BS EN ISO 19115-2:2010. BS EN ISO 19115-2:2019 includes some technical changes with respect to BS EN ISO 19115-2:2010. These include:
- The name and scope were changed to better describe the purpose of the document
- QE Coverage Result and QE Useability were moved to ISO 19157
- All extended classes now extend ISO 191151:2014
- Whereas the XML Schema encoding for ISO 19115-2:2009 was provided in ISO/TS 191392 the link and information about the XML schema for this revision is provided in Annex C of this document
- A specified class of MI_Instrument – MI_Sensor was defined. A list of all the parts in the ISO 19115 series, can be found on the ISO website
