Electronic chart element conversion method for port water area planning

The invention discloses an electronic chart element conversion method for port water area planning, and the method comprises the steps: opening electronic chart water depth point data in batches through FME software, selecting a conversion output format, carrying out the data conversion, and extracting the water depth point data after the format conversion; the method comprises the following steps: performing coordinate projection and conversion on water depth point data of a target electronic chart by applying ArcGIS software, and storing the water depth point data in a format compatible with AutoCAD software; using AutoCAD software to display the position coordinates of the water depth point and extract the water depth coordinates; and an AutoCAD plug-in is applied to correctly display the number representing the water depth on the point location, so that the target electronic chart is converted into a file in an AutoCAD format in a lossless manner. According to the method, the water depth point, the isobat
