Overview

This export is available in DELFT-FEWS versions after 13-5-2013 (FEWS version 2013.01)

The IDF serializer exports coverage data to iMOD IDF files. This binary file type is described in the iMOD manual. Note there is an error in the IDF specification. The first two fields of the comment section, parameter names lAdit and Nline, are not Integer 1, but Integer 4.

Conversion details

The internal FEWS data format is more descriptive than the IDF format. The needed conversions and adaptations are mentioned here.

Restrictions

Only time series content with a single time series and a single content time can be serialized.

Coordinates

In IDF, the bounding box coordinates are specified by their X and Y coordinate. Their coordinate system is not explicitly stored. The name of the used geo datum is stored in the IDF comment.

No Data Value

The IDF No Data value is always Float.NaN.

Top and Bottom Values

FEWS supports a top and bottom value for each cell, whereas IDF only supports a single top and bottom for the whole grid. Only the values of the first cell are considered when exporting. If either of these values is Double.NaN, it is assumed the top and bottom values are not used.

Comment

The comment as written in the IDF file is specified as follows.
If time series content comment is not null or empty:

[Time Series Content Comment] + "\r\n" + [Geo Datum Name]

else:

[Geo Datum Name]
