Issues with FRAGSTATS comparison

Closed this issue · 1 comments

Related to 28ca236

There are a few metrics which have some deviations from FRAGSTATS which can not be explained by numeric differences. Mostly, they seem to be related to the core area and and the augusta landscape. But also other issues seem to be present.

Currently the test are commented out.

Patch level

  • gyrate
  • ncore
  • shape

Class level

  • dcad
  • ndca
  • tca

landscape

  • ndca
  • tca
  • dcad

Also, kind of related. Given we already test metrics on patch level, I don't compare the distribution of them on class and landscape level. If the patch-scale is identical, also mean, sd, and cv must be.

Sorry, wrong issue. Should be #294
