Which statement about geometry creation from coordinates in CSV/Excel workflows is true?

• A. It requires GML first.
• B. Geometry can never be created automatically from coordinates in these readers.
• C. You must use a JavaScript transformer.
• D. If coordinates are stored in standard names, the reader can automatically create geometry.

Answer: (D)

Coordinate fields named in standard ways are enough for the reader to create geometry automatically. In CSV/Excel workflows, if the coordinate columns use widely recognized names (such as X and Y for 2D, or Longitude and Latitude for geographic data, optionally including Z), the reader can directly construct point geometries during import. This eliminates the need for a separate step to build geometry, so downstream processes receive ready-to-use geometries.

GML is not a prerequisite, and you don’t need a JavaScript transformer to get geometry. The automatic creation hinges on the field names matching what the reader expects. If the coordinate names aren’t standard, you’d need to rename them or explicitly create geometry with a transformer.
