Spatial data integration can require projecting multiple datasets with various coordinate systems into a single output using one coordinate system.

• A. True
• B. False
• C. Not Applicable
• D. Both

Answer: (A)

In spatial data integration, aligning data from different sources often requires a common frame of reference. When datasets come with different coordinate systems, their features may not line up correctly on a map. To ensure accurate overlay and analysis, you reproject the inputs into a single, common output coordinate system. This reprojection transforms each dataset’s coordinates to the target CRS so that all features share the same spatial framework. The chosen output CRS is typically suited to the area of interest and the desired measurements; sometimes all inputs are already in that CRS and no reprojection is needed, but in many workflows reprojection is indeed required to achieve correct integration.
