The authors describe the process of office mine-survey geodetic and cartographic works at the fields of PLC Gazprom Dobycha Yamburg using one of the world`s most widespread geographic information systems (GIS) MapInfo. However, it does not have a sufficient number of ready-made tools designed to solve narrowly focused, practical tasks in underground surveying. In particular, at performing works on arranging plane-and-height measurement of pipelines at the Yamburg oil and gas condensate field, they faced the problem of lacking the necessary tools for creating their lengthwise profiles. Using the capabilities of the program, to automate the construction of the mentioned profiles and increase the economic efficiency of the production process in the MapInfo GIS in the MapBasic programming language, a software module "Construction of various purposes pipelines’ lengthwise profiles" was created. The module is designed to automate the processes of constructing such profiles, piping of gas well clusters, gas pipelines-collectors, on-site networks for different goals, associated with the multiple repetitions of many operations previously performed manually. The construction of a lengthwise profile in this software product enables eliminating errors at transferring marks obtained as a result of field changes. The use of the software module can significantly reduce the time at preparation of reporting as- built documentation.
