I'm having problems importing a grid via the Surfaces>Import Grid File menu option.

Occurrence

Using any of the grid import tools accessed via the Surfaces>Import Grid File menu option.

Solution

This tool set comprises mostly 'legacy' grid import tools, that can cause a number of issues.

We strongly recommend always importing the following grid formats via the standard MapInfo Professional File>Open (CTRL+O) menu option, setting the Files of Type to 'Grid Image':

 - BIL
 - ER Mapper
 - Geosoft
 - Surfer
 - Vertical Mapper
 - ESRI ASCII
 - USGS SDTS TAR
 - Minex

ASCII grids are best imported via the Surfaces>Create Grid>Large and Multi-File option, using the 'Stamp only' Method.

HGT grids are the only grid format that must be imported via the Surfaces>Import Grid File menu option.
