Neara

Importing Survey Files

Neara will automatically centre the design from the imported file.  If data is already present with meaningful coordinates, and the data that is being imported is "far away" from that data, you might see this warning:

"WARNING: The specified design centre is outside the bounds of the imported file by xx km

To ignore, click here to update the easting/northing from the DXF centre"

This is due to a big offset distance between the centre of the import file and the centre of the current work space. By default, the centre of a blank work space will be X:0 Y:0. The centre of a imported file is typically in a global coordinate system of some kind. These two centres can be many kilometers away.  If unadjusted, the work space will appear blank after an import as there is no data at X:0 Y:0 of the import file.

To update the work space centre in Neara, either :

1. Enter in the easting and northing coordinate of your choice in the Local Coord Offset field

OR

2. Click the update link in the warning message. This will be a centre automatically calculated from the import file.

Note: where option 2 is chosen, you may still encounter a blank work space. This is because the centre of the import file is blank. The user will need to manually enter in the easting and northing to an area that has data.

Setting up the coordinate system

It is possible to make Neara aware of the coordinate system used in the design, by specifying its EPSG code.  This will allow Neara to know how to map X,Y coordinates to Lat,Lng, so that maps imagery can be displayed and correctly lined up.

Once the survey data is imported (whether CSV, DXF, LiDAR, etc), go to the map tool, and click "Edit" as per the screenshot below:

Enter the EPSG code for your survey data's coordinate system.  You will see the WKT definition for that coordinate system displayed.

Then, click "Apply" to line up the maps imagery lat/lng as per below:

Alternatively, in rare circumstances, if you had started your design by clicking on the map view to bring in some maps imagery, and subsequently want to have matching X,Y coordinates (not with survey data), you can select "derive coord from lat/lng".
