に基づいて says something is grounded in facts, rules or data: この映画は実話に基づいて作られた, "this film is based on a true story".
The basis is usually something objective and authoritative: a law, research results, data, a contract, experience. The second half is a judgement, a plan or something produced from it.
Before a noun, it becomes に基づく: データに基づく分析, "data-based analysis". In formal writing, に基づき.
It's close to をもとに. に基づいて stresses staying faithful to a standard or evidence; をもとに is looser, more about raw material you build from.
