Introduction

This document is a reference manual that deals with the standard SEDRIS functions, as well as critical data structures. The parameters associated with each function are detailed, and the resultant processing is described.

For general information about this release, where to obtain it, and items that require specific attention, see the Release Notes.

The SEDRIS Technology Components are:

Data Representation Model (DRM)
Through the use of the data representation model, users of SEDRIS can describe and articulate their environmental data clearly, while at the same time using the same representation model to understand data from other users unambiguously. The SEDRIS DRM is an object-oriented data representation model, and provides a unified method for describing all data elements, and their logical relationships, needed to express environmental data in a seamless manner across all environmental domains.


Environmental Data Coding Specification (EDCS)
The concepts embodied by SEDRIS often require indicating information about the data in a SEDRIS transmittal. This information is provided in the form of classifications of the data, and attributes defining properties of the data. The EDCS defines the allowed classifications and attributes, and also provides a mechanism for specifying new classifications and attributes. Since attributes have data associated with them, the EDCS also defines codes for indicating the units of measure in which an attribute value is specified, and codes for indicating the meanings of enumerated values.


Spatial Reference Model (SRM)
The geospatial concepts used within SEDRIS are defined by the SRM. This includes not only the formal definitions of the various spatial reference frames, but also the coordinate systems used within them and the reference objects to which they are attached. The SRM also provides standard functionality for converting geospatial positions from one spatial reference frame to another.


Transmittal Access Application Programmer's Interface (API)
SEDRIS provides a standard API to manipulate SEDRIS transmittals. The API allows users of SEDRIS to ignore media and implementation details by abstracting SEDRIS data through the API. The API provides transmittal manipulation capabilities through object retrieval, creation, and modification functionality.


SEDRIS Transmittal Format (STF)
Provides users of SEDRIS, both data consumers and data providers, with a means of cross-platform interchange by supplying a universally specified external storage format.
