Import an empty 1d_nwk layer and save in the “model\mi” folder. Add the layer to your GIS work environment and make it editable. Digitise 1D channels ensuring they are snapped at each ends. As they are digitised, enter the channel ID and the other attributes according to the type of channel (see Table 4 .10). Note: it is no longer a requirement to digitise nodes (see Section 3.12.1). Setup any links to cross-section data, etc. There are a number of ways to manage cross-sections (eg. using .csv files, MIKE 11 or ISIS cross-section database or the traditional fixed field CS tables).
Use Read MI Network in the .ecf file to read the 1d_nwk layer(s) developed as follows.
