#290 closed feature (wontfix)

stats() function in rasdaman

Reported by: dmisev Owned by: dmisev
Priority: minor Milestone:
Component: qlparser Version:
Keywords: Cc: abeccati
Complexity: Very Hard

Description

gdalinfo has a -stats option which computes min, max, mean, stddev.

It doesn't hurt to have something similar in rasdaman for getting some quick idea about the data. The result of stats() could be encoded as a struct of floats.

E.g.

$ rasql -q 'select stats(c) from lena as c' --out string

Output (max, min, mean, stddev, ...)

  Result element 1: { 249, 12, 108.83, 50.14, ...}
