This paper deals with a tool that enables import of the coded data in a single<br />text file to more than one vector layers (including attribute tables), together with<br />automatic drawing of line and polygon objects and with optional conversion to<br />CAD. Python script v.in.survey is available as an add-on for open-source software<br />GRASS GIS (GRASS Development Team). The paper describes a case study based<br />on surveying at the archaeological mission at Tell-el Retaba (Egypt). Advantages<br />of the tool (e.g. significant optimization of surveying work) and its limits (demands<br />on keeping conventions for the points’ names coding) are discussed here as well.<br />Possibilities of future development are suggested (e.g. generalization of points’<br />names coding or more complex attribute table creation).
