Shall serve a dual purpose of positioning points to facilitate the survey of land parcels in difficult areas where it satisfies the accuracy standard set by the principle of graduated accuracy, consistent with land use, as may be specified by instructions, or provide graphical positioning of unavailable map detail for completion of the LIM. Detailed instructions on the procedures shall be issued by the LMB Director.

• A. Orthophoto Map
• B. Digital (Softcopy) Maps
• C. Municipal Boundary and Index Map
• D. Real (Hardcopy) Maps

Answer: (A)

Orthophoto maps provide true-scale, orthorectified imagery that can be used as an accurate basemap for locating survey points in challenging terrain while meeting the graduated accuracy standards tied to land use as may be directed by the LMB Director. Because they are geometrically corrected, orthophotos remove distortions from terrain and sensor geometry, allowing precise positioning and measurement on the ground. They also offer graphical positioning of map details that may be unavailable in existing LIM data, making them particularly useful for completing LIM requirements. The other options lack this combination: generic digital softcopy maps may not guarantee orthometric accuracy across the sheet; municipal boundary and index maps focus on boundaries rather than precise field positioning or filling in missing details; hardcopy maps are fixed, potentially outdated, and less adaptable for integrating new or missing details.
