How to store 3D data

[baiwenbo1997]

Hello, the field type created by me is geo_shape parameter ignore_z_value set to true, but the regular WKT format storage is not supported. If I don't add a new field Z-value, how do I store it?
。
Here's the data I used
LINESTRING Z(-70.96740547588006 41.64406779661017 0,-74.17079530638853 5.913950456323334 0)

Thanks very much for your interest in Elasticsearch.

Please note that according to our documentation and this PR, adding Z values (source only) to geo_shape fields should be supported. Lacking enough information to support a bug case, this appears to be a user question, and we'd like to direct these kinds of things to the forums. If you can stop by there, we'd appreciate it. This allows us to use GitHub for verified bug reports, feature requests, and pull requests.

There's an active community in the forums that should be able to help get an answer to your question. As such, I hope you don't mind that I close this.
