Conversion of Electronic Navigational Charts from S-57 to S-101 Standard Format

Abstract

With the advance of technology, the S-57 standard format has become rigid and inflexible, creating a need for a new standard of information exchange. The IHO published the S-100 standard which enables the exchange of information of various types, among them ENC S-101. Therefore, an update of the ENC from S-57 to S-101 will be necessary. In order to facilitate an efficient conversion, IHO, through ESRI, developed specialized conversion software. This article aims to test the converter provided by the IHO/ESRI/NOAA partnership and analyze the results, presenting possible causes of errors and solutions, through the use of a Brazilian sample of S-57 ENC.
