Standardization)is a worldwidefederation of national standards bodies (ISO member bodies).The work ofpreparing International Standards is normally carried out through ISOtechnical committees.Each member body interested in a subject for whicha technical committee has been established has the right to berepresented on that committee.International organizations,governmentaland non-governmental,in liaison with ISO,also take part in the work.ISOcollaborates closely with the International Electrotechnical Commission(IEC)on all matters of electrotechnical standardization.  \nDraft International Standards adopted by the technical committees arecirculated to the member bodies for voting.Publication as an InternationalStandard requires approval by at least 75%of the member bodies castinga vote.

Scope\n\nThis International Standard establishes general rules and specifies graphical symbols and simplified representationsfor landscape drawing practice.  \nThe graphical symbols and simplified representation are jointly referred to as conventions.The conventions given inInternational Standards which are applicable to landscape drawings are presented in annex A.  \n## 2 General rules\n\nTeh STANDARD PRE  \nThe extent of information shown on landscape drawings will depend on the degree of accuracy required by thetype of work.(standards.iteh.ai)  \nProduction drawings shall be adequately dimensioned to allow for accurate setting out.  \nIn certain circumstances\"itis desirable to make final adjustmentson°site-(e.g.?tree positions).In such casesdrawings shall be suitably annotated.3a394b6060a4/iSO  \nExisting and proposed levels shall be shown,either as spot levels or as contours or both where appropriate.Thevertical interval of contours and the spacing of grid levels depend on the character of the site and the nature of theproject.  \nSimilar areas shown on different drawings should be appropriately cross-referenced.  \n## 3 Conventions\n\nIf necessary,the convention (graphical symbol or simplified representation)can be completed by  \n—text;  \n—designations or abbreviations explained on the drawing or associated documents;  \n一complementary additions to conventions in order to communicate further information.  \nNonstandardized conventions shall be explained on the drawing.  \nISO 11091:1994(E)  \n\n| Reference  \u003Cbr>No.   | Element   |
