comment How to join multiple records to single feature?
What is the end-result you want to achieve? Even if you manage to do a join, do you want to present it on a map? Do statistics? Depending on that, different workflows may be followed, but using a database is usually a good idea if you want to make joins.

comment Land Cover Feature Extraction from Satellite Imagery
Provide more info (in your question, not in comments) what exactly the features are that you want to extract. Apart from that: if there is an overlap in the signal (see nasa link) of different land-use types (or whatever you are mapping), automated classification will not work well.

This approach uses only one raster - which is usually insufficient.

This fix is better than mine because the data points in the caspian sea are also converted (these points are also negative). Nice!
