You will now be able to add compatible QGIS SHP format files to your model.<br>
 
It is best practice to leave the MapInfo file references as is, and use TUFLOW's datalayeringdata layering functionality the add new GIS entries below existing MapInfo entries. For example.
 
 
If you need to make changes to existing MIF files, follow these steps:
<ol>
<li> Open the the MapInfo MIF file in GIS. If the file includes a combaintioncombination of regions, lines and points QGIS will display a pop up message asking which of these features you would like to open. Select all. QGIS will split the MIF file into it's respective object types.
<li> Import empty QGIS SHP template files for the required object types.
<li> Copy the features from the MapInfo object tye layers to tehthe relevent new QGIS SHP files. NOteNote, double check the attribute values have been correctly transferedtransferred to the new file. In some rare instances, when the field attribute type is incompatible this does not occur.
<li> Update the commands within your updated TUFLOwTUFLOW model to reference to the new QGIS SHP files. For future tracabilitytraceability it is best to comment out the prior MapInfo input commands, instead of deleting them.
