Topography, cadastral and 3D models

Topko Express is SierraSoft entry-level product, which offers, at a very competitive price, sophisticated tools for topography, cadaster and 3D management of survey. Topko Express is addressed to those technicians who need a fast software, practical and easy to use for the management of topographic and cadastral works. By Topko Express it is also possible to generate sections, create terrain numeric models and calculate volumes.

Survey drawing The whole drawing is completely under the user control and the user can modify sizes and symbol to be used even for a single point. Texts can 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. Instrument system and data recorders Data insert The tool allows to acquire data from the most widespread field data recorders. Topko is equipped both with interface procedure with data recorder, and with procedures for conversion of file into original recorder formats. Topko also provides functions for uploading (in field data recorder) fieldbook measures and coordinates of the points calculated inside the program. b bdlld e move d manua lly an d p oint The tool flexibility allows different opportunities of survey data insert. Data can be inserted from keyboard, through digitizer, text-file (ASCII), from DWG/DXF file and graphically. symbols can be rotated. Utilities and technical calculations Different topographic utilities have been arranged, among which: Intersection angle-angle (2D and 3D); Resection 3 points; Triangle resolution; Coordinate transformations Resection 2 points; Rototranslation functions (with or without scale variation) allowing to perform cartographic insertions of field surveys. Generation of virtual stations and points referred to them; Tachimetric sight sorting; Generation of sights from coordinates (tachimetric and chains and offsets). Survey calculation Calculation and empiric adjustment of a closed traverse or a constrained traverse and elaboration of field surveys with average of multiple stations and management of reverse sights, triangulations and trilaterations. Possible correction of field sights (earth sphericity, refraction). The results of survey calculation are displayed in a tree structure that is easy to consult and allows to verify any result by going back to the measures that determined it. All the results can be printed on predefined reports personalisable by the user.
