Bearings and distances of the individual lots are determined using transit and stadia, scaling from photo map, and other graphical methods.

• A. Cadastral Surveys
• B. Public Land Subdivision
• C. Isolated Surveys
• D. Graphical Cadastre

Answer: (D)

The scenario describes using graphical techniques to lay out parcels: bearings and distances are obtained through measurements with tools like a transit and stadia, then scaled from a photo map or other graphic bases, and plotted using graphical methods. This is the essence of a graphical cadastre, where the boundaries are prepared on a map by graphic construction rather than by running every line in the field as a strict traverse.

Cadastral surveys, by contrast, emphasize field surveys to determine and certify exact boundary lines for titles. Isolated surveys deal with a single parcel, not a whole subdivision, and public land subdivision refers to the administrative process of dividing government land into parcels, not the specific method of deriving boundaries graphically. The described method—combining transit, stadia, and scaling from photographic or graphic bases—aligns with graphical cadastre.
