The Spatial Reference Model (SRM)is a general concept

There are two aspects of the SRM discussed in this tutorial

• One aspect is the SRM as an International Standard.

- ISO/IEC 18026 Spatial Reference Model.

- Under development, the final committee draft is to be released summer ‘04.

- This tutorial uses the nomenclature, definitions and

concepts of ISO/IEC 18026.

- Consistency with other International Standards is promoted.

- Efficiency of algorithms or their implementation is not part of the

ISO/IEC 18026 specification.

• Another aspect is the implementation of the SRM in SEDRIS

- The SEDRIS implementation is designed to be compliant with the

emerging 18026 International Standard.

- The SEDRIS implementation is an application driven development.

- A software architecture and spatial operations API is required.

- Algorithms for spatial operations in spatial frames are designed to be accurate robust and efficient.

- The SEDRIS software has been subject to extensive testing.
