If the sewer line as-built drawings for a small municipality have been scanned into a file for developing a geographic information system feature class, what is the most likely structure of the resultant file?
  1. Metadata structure
  2. Vector structure
  3. Database structure
  4. Raster structure
Explanation
Answer: D - If the sewer line as-built drawings for a small municipality have been scanned into a file for developing a geographic information feature class, the most likely structure of the resultant file is a raster structure. Raster images are created when drawings are scanned. Raster images need to be converted to vectors (mathematically defined entities drawn between coordinates) to be used to develop GIS feature classes.
