Data Classification and Encoding Guide

DRAFT

OverviewPrefaceComment by briana sullivan: I would expect to read a clear and concise overview of the entire document in this preface. Something that would explain the contents and their relationships as well as guide the encoder on how to best use it. Avoiding unnecessary explanations of the S-122 Product Specification that dont help in the understanding of the classification and encoding of the data. I say this in the hopes we make this document the best that it can be, not just following what others have done but making it more understandable, with clearer language and break out of the standards languageremembering the S-100s goal to gear the products to users that are not just ECDIS compliant, but from many different domains!For example: POSSIBLE REWRITEEncoding is the process of coding geographic information defined by application schemas into a system-independent data structure suitable for transport and storage. The inverse process is called decoding. The resulting data structure may be stored on digital media or transfe
