| any result by going back to the measures that determined it. All the results can be printed on predefined reports personalisable by the user. Geometric levelling Levelling data can be inserted in a specific table and elaborated in order to calculate point elevation. Subdivision of parcels By calculating automatically the subdivision line, the tool allows to define the value of the area to separate from the parcel. The subdivision line can be: passing through one point, through two points, parallel or perpendicular by two points (to one side or to any direction). If requested, Topko can insert points for building the subdivision line and creates automatically the two parcels resulting from the division. A specific command allows to manage easily expropriation procedure: according to the dividing lines and to the parcels to be expropriated, the tool determines the resulting parcels. COGO COGO commands allow to create quickly and with great precision new survey points by intersection, chain and offset, tangent, alignment, projection, etc., making faster such operations as drawing and data input. Survey codes By using field codes it is possible to generate automatically the drawing lines or the break lines of the digital model and obtain automatically the drawing of the survey. It is possible to assign to any code different parameters by which to represent the point, such as symbol, size, layer. Coordinate transformations Transformation of Cassini coordinate system into Gauss-Boaga coordinate system and vice versa. Transformation of geographic coordinates (latitude and longitude) into other plane coordinate systems and vice versa. Rototranslation functions (with or without scale variation) allowing to perform cartographic insertions of field surveys. It is possible to assign to check points some weights, which can also be calculated automatically by the tool according to the distance from the barycentre and to the point reliability. |
