Program complex “Mining and geodetic networks and survey” (MGNetwork)

Program complex “MGNetworks” is built on the basis of the following principles:

Principle of “constructive simplicity of forming initial information”. Complex measurement on the station is the basic building element, with which any network is built. In total these data entirely determine the network type, its topology and calculation scheme, that’s why measurement data on the station constitute information unit about the network regardless of its type and topology. The order of station measurement sequence is free. This helps to almost entirely eliminate the drawbacks of existing programs, noted above in points 1–5.
Principle of “stability calculation algorithm” i.e. regardless of rough errors of data or their incompleteness, calculation results give clear picture about the network structure and its drawbacks, or they localize rough errors. This makes possible the calculation of any networks including free ones, or combination in one project of several networks with different available level of initial data.
Realization of these principles makes possible to use flexible technologies of network processing.
In particular, “additive network technology”, i.e. after inputing data from one or more station the network can be controlled in its current configuration. It lets fast revealing of rough errors and maintaining of correct topology of the network. The unique possibility of discrepancy feasibility check of all conditional equations, appearing in the network, regardless of its type and topology, give objective and full picture about the quality and accuracy of measurements.

Program complex “Mining and geodetic networks and survey” (MGNetwork)

Program complex “Mining and geodetic networks and survey” (MGNetwork) is intended for design, accuracy precalculation and equalization of horizontal-vertical networks of random configuration. This complex includes unique possibilities for equalization of any networks and search for rough errors.

Well-known program complexes for building and adjusting horizontal and vertical networks, used in practice, have a number of drawbacks, among which the main ones should be pointed out:

they require differentiation of horizontal and vertical networks;
they require differentiation of network types (polygonometric, triangulation, trilateration or line-and-angle);
the user should clearly understand the topology of the network and, at least partially, encode it by some means or other;
the order of data input is determined, both in sequence of points and in measurements on them;
some cases require approximate coordinate values of determined points;
discrepancies of all conditional equations, which take place in any particular network, are not determined nor analyzed;
the network must by all means have basic initial data;
in searching rough errors the technology which is used for data preparation for structural network variants is rather cumbersome and time-consuming;
non-sufficient calculation stability when there are rough errors in the network or when the network has geometrical ambiguity.

Network accuracy precalculation

Designing mining and geodetic networks based on raster image

For mining networks equalization of hyroscopic sides is required, taking into account orientation errors. There are functions for precalculation of distant network point accuracy and precalculation of breakthough accuracy, carried out by counter headways.
