Are there things similar to NGS Survey Marks in India?
https://www.ngs.noaa.gov/datasheets/ https://en.m.wikipedia.org/wiki/Survey_marker *Survey markers*, also called *survey marks*, *survey monuments*, *survey benchmarks* or *geodetic marks*, are objects placed to mark key survey <https://en.m.wikipedia.org/wiki/Surveying> points on the Earth's surface. They are used in geodetic <https://en.m.wikipedia.org/wiki/Geodesy> and land surveying <https://en.m.wikipedia.org/wiki/Surveying>. Informally, such marks are referred to as benchmarks <https://en.m.wikipedia.org/wiki/Benchmark_%28surveying%29>,[1] <https://en.m.wikipedia.org/wiki/Survey_marker#cite_note-1> although strictly speaking the term "benchmark" is reserved for marks that indicate elevation. Horizontal position markers used for triangulation <https://en.m.wikipedia.org/wiki/Triangulation> are also known as triangulation stations <https://en.m.wikipedia.org/wiki/Triangulation_station>.
