coordlnata protrectrsr-A square-shaped
protractor having graduations on two adjacent
edges wtih the cemer al one comer. II is

coordlnation+wrveying) The placing of all
survey data on the same aocmlnale system or
datum. Coordination does not hrrply the
adjustment of obsemaIlons to rarrmve
discrepancies. Two field surveys over the same
area may be coordinated by computation on tha
