International Standards which are applicable to landscape drawings are presented in annex A. 2 General rules The extent of information shown on landscape drawings will depend on the degree of accuracy required by the type of work. Production drawings shall be adequately dimensioned to allow for accurate setting out. In certain circumstances it is desirable to make final adjustments on site (e.g. tree positions). In such cases drawings shall be suitably annotated. Existing and proposed levels shall be shown, either as spot levels or as contours or both where appropriate. The vertical interval of contours and the spacing of grid levels depend on the character of the site and the nature of the project. Similar areas shown on different drawings should be appropriately cross-referenced 3Conventions If necessary, the convention (graphical symbol or simplified representation) can be completed by 一 text; - designations or abbreviations explained on the drawing or associated documents: complementary additions to conventions in order to communicate further information Nonstandardized conventions shall be explained on the drawing.
