About reading mrr

[Mizuno]

When a simple mrr created with Planet (Mapinfo) is read into Alteryx, the shape of the object is imported as a polygon different from the original shape. Are there any countermeasures?

Could you provide a .mrr file?

[Mizuno]

The mrr used was converted from Tab to mrr with Planet's RasterizeToll

[prozanini]

Opening the .tab file you sent in a text editor, we have:

!table
!version 300
!charset WindowsJapanese

Could those 4 coordinates be the corners of the square? It seems like either you converted the wrong file or, indeed the conversion tool wasn't properly set. Was that the original .tab file?

Hello Eveyrone

Got also some troubles using the .mrr files in Alteryx.

Tried to make a contour and got some strange results , part of the raster are duplicates multiple times with an offset about 30km to the east.

Also got this strange square on the top but manage to remove by filtering all the cell with a 0 value 

 Raster in on the left, contour are in black

Here an example, Raster on the left, resulting contours in black.

Seven contours created and only one is correct, distance about 30km between each of them
