Cannot perform coregistration with Land Cover dataset
Expected behavior
@forman @JanisGailis Expect to be able to coregister Land Cover dataset with other datasets
Actual behavior
1. Using Land Cover as master dataset
Invalid input message is displayed: Oops, cate couldn't carry out the request Executing operation "coregister" because: The master dataset grid is not equidistant, can not perform coregistration
Example traceback :

Steps to reproduce the problem
- Download / open esacci.LC.5-yrs.L4.LCCS.multi-sensor.multi-platform.Map.1-6-1.r1
- Download / open other dataset
- Select coregistration operation, select master and slave datasets and use default parameters.

@JanisGailis the LC dataset should be equirectangular WGS-84, so it should be equidistant.
Yes, it is, I checked this quickly. This seems to be due to floating point precision, a single LC pixel is a rounding error for the other dataset. It should be possible to solve this by checking for lat/lon lengths and doing things differently if one of the datasets is on a very fine grid.
It's a shame that we got a working LC dataset into the portal and started testing with it so late in the process.
