There are several different types of source data that a user may access when producing nautical data within ArcGIS Maritime. However, most fall into one of two categories—raster and vector. With ArcGIS Maritime, you can use a variety of raster formats as source data for your ENC (Electronic Navigational Charts) production efforts. See the list of supported raster formats for more details. When performing data production or maintenance, the editor will often load a raster image as a backdrop layer. If the raster image is not georeferenced, the editor will need to georeference the image before it is a viable source. Using the layer transparency settings allows you to collect your data on top of the raster layer without having to worry about the draw order. You can use the Feature Manager window to select the appropriate feature class or subtype before digitizing from the raster.
Vector data, the second major type of source data, can come in many different formats, including shapefiles, ArcGIS Desktop Advanced coverages, DGN (design), and many more. Existing S-57 data can be imported directly into the geodatabase using the S-57 to Geodatabase geoprocessing tool. The ArcGIS Data Interoperability extension further expands the number of third-party software formats available as sources for ArcGIS Desktop.
For vector source data, you can use the copy and paste tools to take the geometry from the source data and put it into your geodatabase. Using the Feature Manager window will help streamline this activity by allowing you to choose the appropriate feature class or subtype for the target layer.
