6.1Add Map

Click the option Add Map from the Map menu to open an IDF-, MDF-, IPF-, IFF-, ISG-, GEN- or ASC-file. Alternatively click on the Add Map button on the iMOD Manager, click on the icon Open Map on the toolbar, or use the shortcut F2 on the keyboard to open the Load iMOD Map window.

Note: To select multiple files, use the combination Shift+left mouse to select adjacent files or use the Ctrl-left mouse button to select files in any order.

Note: Whenever an ASC-file is opened (see section 9.14 for the syntax of an ASC-file), iMOD will convert these file into IDF format and write them in the same folder. Whenever such a file exists, you will be asked to overwrite it.

Note: Whenever NC-file (NetCDF) is opened, iMOD will convert these file into IDF format and write them in the same folder. Since, a NetCDF file is general file format iMOD can not convert this type of a file without the interference of the user. Here for, iMOD will display the following window in which the user can specify the correct attributes for the x- and y-coordinate and the actual data block to be converted. This function is only available in the X32-bits version of iMOD.

Configure NetCDF
Import

This treeview lists the content of the selected NetCDF file. iMOD needs an attribute for the x- and y-coordinates and an actual data block. In the example presented above, these are the attributes x, y and Band1. The x- and y-coordinates (actual the mids of the gridcells) need to be stored in an one dimensional array (ndim=1) and the data block in a two dimensional array (ndim=2). iMOD will compute the cell size that is needed for the formulation of an IDF file, which can be equidistant en non-equidistant.

Import Variable

Select an available variable that is stored by a two dimensional array in the NetCDF, e.g. Band1.

X-Coord.:

Select an available variable that is stored by an one dimensional array in the NetCDF for the representation of the x-coordinate, e.g. x.

Y-Coord.:

Select an available variable that is stored by an one dimensional array in the NetCDF for the representation of the y-coordinate, e.g. y.

Import As:

Select one of the following options to store the converted NetCDF file:

  • IDF
    Select this option to generate an IDF file;

  • IPF
    Select this option to generate an IPF file, each point in the IPF file represents the location as described by the selected x- and y-variable;

NoData Value

Select an available variable to represent the NodataValue of the data block. iMOD will fill in the corresponding value in the input field to the right.

Close

Click this button to close the NetCDF Content window without converting the NetCDF file into an IDF.

OK

Click this button to convert the NetCDF into an IDF file and close the NetCDF Content window.
