How does DMC 2010-13 address the use of satellite imagery in land surveys?

• A. It is prohibited
• B. It is optional and based on surveyor's discretion
• C. It is mandatory for all surveys
• D. It is encouraged but must be supplemented by ground surveys

Answer: (C)

The main concept tested is that satellite imagery is treated as a compulsory baseline in all land surveys under DMC 2010-13. This policy makes satellite imagery a required starting point for every survey, ensuring a current, georeferenced reference framework that all practitioners use. By mandating imagery, the standard promotes consistency across projects, improves accuracy in delineating parcel boundaries, and aligns survey work with a common coordinate reference system. Ground verification remains important to confirm on-the-ground details and capture specifics that imagery alone cannot, but the imagery itself must be used as part of every survey. That’s why choosing the option that satellite imagery is mandatory for all surveys best reflects the rule.
