The Environmental Research Institute of Michigan ERIM was contracted by the United States Coast Guard Research and Development Center through the Naval Coastal Systems Center to prepare a set of technical and functional specifications that detail the meansprocesses required to perform the conversion of an Electronic Navigational Chart ENC in the DX90 Data Transfer Standard format into a System Electronic Navigational Chart SENC. This report details the activities associated with transforming the DX90 data structures to an intermediary ENC format, developing the software to transform this intermediary ENC to a form which could be displayed SENC, and developing display software to allow an operator to interact with the data. Based on these activities, insights were gained into the current status of the implementation of the DX90 standard as well as the strengths and limitations of this format to support Electronic Chart Display and Information System ECDIS applications. Outputs from this contract include this report and software to perform the data conversion and display functions on an IBM-compatible personal computer. Software may be requested through the Coast Guard Research and Development Center.
