device used in surveying and related disciplines to provide a solid and level surface on which to make field drawings, charts and maps
Kasutamisel seatakse plaanistuslaud mõõtepunkti kohale ja sätitakse täpselt horisontaalseks, selle pinnale kinnitatakse joonistusleht ja huvipakkuvate objektide vaatamiseks ja mõõtmiseks kasutatakse alidaadi.
In use, a plane table is set over a point and brought to precise horizontal level. A drawing sheet is attached to the surface and an alidade is used to sight objects of interest. The alidade, in modern examples of the instrument a rule with a telescopic sight, can then be used to construct a line on the drawing that is in the direction of the object of interest.
