TUFLOW Message 2073: Difference between revisions

[[WARNING]]

|message_desc=|message_desc=The GIS object has been ignored. There are two reasons that this can occur:

Various GIS packages handle the advanced GIS geometries (such as arcs) differently, for example if converting a MapInfo Arc object using QGIS, the arc object is converted to a polyline with vertices along the length. For consistency between packages and to provide better support across GIS platforms not all GIS geometries are supported by TUFLOW. For lines, arc objects are not supported (but line and polyline objects are both recognised). For region objects rectangles, rounded rectangles and ellipses are not supported.<br>

Two special cases of unsupported geometries are “Text” objects, which can be used to annotate GIS layers, and “None” or “Null” objects, which GIS software may add to the layer to indicate deleted objects (particularly if using the shapefile format).<br>

</pre>

The default for unsupported objects is ERROR with severity level 1, that is arcs, ellipses, rectangle and rounded rectangles will cause the simulation to stop, but any None and Text objects will be ignored.

The second reason for an object being ignored is that at this stage in the processing, only a specific type of GIS data is expected. For example, when the command "<font color="blue"><tt>Read GIS RF Point </tt></font> <font color="red"><tt>==</tt></font><tt> <gis file></tt>" is specified, only point objects are being read by TUFLOW and lines and regions will be ignored.<br>

For the 2016 release of TUFLOW this can be set to either a Warning or Error using the command:<br>

<font color="blue"><tt>GIS Supported Object Ignored </tt></font> <font color="red"><tt>==</tt></font><tt> WARNING</tt><br>

The default approach is for a Warning to be output.

|suggestions=Ensure that the data in the specified is correct. <br>
