Abstract

The pourpose of this work, started with the Progetto Verde Milano in 2004, is the definition of the measuring procedure and of the statement of contents to use to implement the topographic database of the green areas with the ones step by step acquired by the Administration of Milan.The data thus collected will respect the conditions that allow the correct updating of the GIS of the green areas. The statement has been edited at first to allow the conversion from CAD files, which cannot be used to implement a thematic GIS, into a shapefile, which is the proper file for a GIS. The document is divided in three parts: 1. technical statement for topographic measuring; 2. contents statement; 3. supplying and graphic reproduction of data. The first part defines the aspects concerning the topographic measuring, specifying the operative steps of the measure taking, the instruments to use, the metrical precision required for every different kind of objects and the positioning procedure in the correct coordinate system. The second part concerns the structure of the database and the definition of the thesaurus of the objects to be measured, in such a way that they correspond to those used in the GIS of the green areas. The third part defines the features of the measuring output, in order to test the conformity of the final data to the measuring and contents specificatios. The structure of this statement makes possible the creation of omogeneous files from different sources. In this way the implementation with new areas follows unique and standard procedure and can be easily managed, as well as correctly represented in the correspondent WebGIS. The format and the contents are conform to the indications IntesaGIS and to the Regional content statement.
