Updating a Grids Cell Size and Root position

[stevegardoll]

Hiya,

Is it possible to update a grid files position and cellsize.

Let say the grids have imported incorrectly and all you need to do to fix them is adjust the cellsize and position. Is this possible and easy to do?

Is it possible to update a table?

Cheers

Steve

If the grid is importing in the wrong area there could be a projection issue. Try re-projecting to the correct system. As far as adjusting cell size there are tools (Re-Sample & Aggregate) to either increase or decrease cell size however you don't often want to do this to interpolated grids unless you have to. Without more information about your specific issue that's the best I can do!

Hope it helps!

Steve,

If the data is already in the wrong location, re-projecting the data to the correct coordinate system will do nothing to resolve the issue.  It will still be in the wrong place.  You need to define the coordinate system to be what the data was collected in.

Most raster data out there doens't need to be imported since we support so many formats.  What did your data start as?  i.e. an ASCII file perhaps?  How did you import your data?  What coordinate system is the data supposed to be in? How is the cellsize defined in whatever format it was in prior to importing?

A few more details from you and I'm sure we can sort it out. What version are you using?

Regards,
Eric
