@vvysotskyi OK, thanks. Currently, gis unit tests only work with CSV
geo-spacial data. It sounds that JSON format is also supported and is not
covered by the gis unit tests. Can you confirm if JSON format is supported and
if yes, whether it is affected by the major version upgrade or not. In case
JSON format is supported, it will be good to cover it in unit tests as well
(not as part of this PR).---
