Why did we replace the GeoTIFF reader with a FeatureReader?

• A. The FeatureReader lets us read only GeoTIFF files that overlap neighborhoods.
• B. The GeoTIFF reader was configured incorrectly.
• C. The GeoTIFF reader is out-of-date.
• D. The FeatureReader can read GeoTIFF files faster than the GeoTIFF reader.

Answer: (A)

The key idea is reading only what you need by applying a spatial filter at read time. A GeoTIFF is a raster file that can be large, and if your analysis focuses on specific neighborhoods, pulling the entire raster wastes time and memory. The FeatureReader can be driven by a geometry (the neighborhoods) and only produce features (tiles or footprints) that overlap that geometry. In practice, this means GeoTIFF tiles that don’t intersect the neighborhoods are never read, making the workflow more efficient. The other options don’t fit because they attribute the change to misconfiguration, obsolescence, or a generic speed advantage, rather than to the ability to selectively read data based on spatial overlap.
