What are the possible effects of working from a different datum?

Working from a different datum can lead to significant discrepancies in data interpretation and analysis. It may result in inconsistencies, errors, or misalignments in measurements, especially in fields like surveying, geospatial analysis, or engineering. Additionally, using an incorrect datum can complicate data integration from various sources, ultimately affecting decision-making and project outcomes. Properly aligning data to a consistent datum is crucial for accuracy and reliability.
