This ensures that incoming files are in the same projection as the TUFLOW model. TUFLOW is not a GIS software and does not use the projection information in each file (apart for the check). TUFLOW uses the co-ordinates of the objects in the GIS layer and locates them in the TUFLOW model. Hence the need for a projection check. All model input files should be in the same projection, if inputs are not in the correct projection the data will be in the wrong location and won't be used. If your model is in for example MGA 94 zone 56, and the 2d materials (2d_mat) file is in the wrong projection (e.g. NSW ISG 56/1), these material polygons will be in the wrong location (probably in the middle of the ocean) and they won't be assigned to any model cells.<br> This message prevents problems with the data provided having a different projection than the TUFLOW model.<br><br> <u>Message Options</u><br> This message can be set to give either an error (this is the default): <br> <font color="~~green~~blue"><tt> SHP Projection Check </tt></font><font color="red"><tt>== </tt></font><font color="black"><tt>ERROR</tt></font><br> <font color="blue"><tt>MI Projection Check </tt></font><font color="red"><tt>== </tt></font><font color="black"><tt>ERROR</tt></font><br> This message can be downgraded to a warning: <br> <font color="~~green~~blue"><tt> SHP Projection Check </tt></font><font color="red"><tt>== </tt></font><font color="black"><tt>WARNING</tt></font><br> <font color="blue"><tt>MI Projection Check </tt></font><font color="red"><tt>== </tt></font><font color="black"><tt>WARNING</tt></font><br> Or this message can be turned off entirely (use with caution - all files should be checked they are in the correct projection!): <br> <font color="~~green~~blue"><tt> SHP Projection Check </tt></font><font color="red"><tt>== </tt></font><font color="black"><tt>OFF</tt></font><br> <font color="blue"><tt>MI Projection Check </tt></font><font color="red"><tt>== </tt></font><font color="black"><tt>OFF</tt></font><br> <br> <u>Projection Files'''</u><br> Line 55: * Select the '''Projection...''' button in the dialogue box * In the '''Choose Projection''' dialogue set the desired projection and save * If the file is in the same projection as the TUFLOW model, compare the projection line from the '''.shp''' or '''.mif''' file with that specified in the <font color="~~green~~blue"><tt>SHP Projection </tt></font><font color="red"><tt>== </tt></font> or <font color="~~green~~blue"><tt>MI Projection </tt></font><font color="red"><tt>== </tt></font> command. If the bounds are different (refer to Examples above), you can overwrite the projection line. This should correct the issue of the TUFLOW error without changing the GIS data. If multiple files are different, this message can be set to warning or OFF (as described above), however you should check all files with this warning to ensure that they are in the same projection.<br> Shapefiles - the '''.prj''' file associated with the shapefile with that in the '''projection.shp'''<br> MIF files - the projection line (line 4) in the problem '''.mif''' file with that in the projection.mif, re-import the file and export the file (backup first). Line 61: * Use the latest TUFLOW release. Since 2020-01-AB release, TUFLOW parses the parameter data into number values and compares each of these numbers to check they are consistent. This should provide a more robust check less prone to falsely flagging the projections as different with "Message 0305" from Example 2. ~~\|discussion_page=* [[Talk:TUFLOW Message 0305\|Discuss Message 0305]]~~ ~~\|link3=''~~ ~~\|link4=''~~ ~~\|prelink=[[TUFLOW_Message_0304\|Message 0304]]~~ \|uplink=[[0xxx_TUFLOW_Messages\|0xxx Messages]] ~~\|nextlink=[[TUFLOW_Message_0306\|Message 0306]]~~ }}
