Digital cartographic materials creation


The initial data for creating and updating digital maps are catalogs of coordinates and altitudes of points of geodetic network, base stations and points imaging network (insignia), remote sensing, survey karmaterialy in the prospecting area. In the formation of the digital cartographic materials the complex of works, among which:


  • Creation and adjustment of digital model of locality for engineering purposes, based on geodetic survey findings;
  • Editing of existing cartographic materials using the modern remote sensing data, high-resolution space images;
  • Formation of digital cartographic materials of various succeeding scales based on the developed digital model of locality: route maps of main pipeline corridor, large-scale plans, map boards, general plans;
  • Preparation of digital cartographic materials for downloading to GIS of various purposes: reduction to unified layer-by-layer structure using the digital libraries of line types and conventional symbols.

Processing of remote sensing  data


Remote sensing data gained wide use as GIS resources, in particular images of land surface with the objects located on it or in the Earth's interior, obtained during the surveys with any remote methods. They are primarily obtained with ground-, air- or space-based survey instruments that allow for having images in one or several sections of electromagnetic specter.  To eliminate the geometric distortions in the images is performed transformation of remote sensing data.


Specialists of our company perform the following works with remote sensing data:


  • Processing of remote sensing materials relating to land: aerophotographs and space images of high resolution made from various satellites;
  • Processing of remote sensing data in PHOTOMOD program module:
  1. Construction and phototriangulational station adjustment;
  2. Construction of digital terrain models (DTM) and horizontals;
  3. Creation of digital orthophotomaps;
  4. Creation and updating of three-dimensional and two-dimensional digital maps of locality based on space and aerial survey.

Creation of 3D models


Up-to-date information technologies are able to provide the operational tasks of production enterprises with the tools for navigation and equipment graphic visualization in two-dimensional and three-dimensional environment, which may be prepared by our company.


Our specialists perform the entire range of works on creation of three-dimensional models of equipment used in complex process systems, including compressor stations, oil refineries and petrochemical plants and other areal facilities, and which includes both field and office works. Data complex of three-dimensional model may include the results of equipment technical inspection (vibrometry, wall thickness test, pit sampling, check points to be verified by acoustic emission method etc.), for convenient analysis of technical condition and visualization of diverse information about the object.


At the stage of field measurements, location and burial depth of underground utility lines are determined, and all utility line wells and tresle sections are sketched. Moreover, images of all objects are taken, both panoramic and minute particulars, and process equipment is inspected visually.


At the stage of office works, the archive data are processed, based on which a layout is designed and the process facility model is developed, using the results of field materials of geodetic works. Three-dimensional model is created in Bentley Microstation environment.

Development and adaptation Classifier of spatial data


Works related to development and adaptation of the corporate Classifier of spatial data aim to describe the object composition of cartographic resources, the ways to depict the objects on the map subject to the scale, to code the objects. Classifier of spatial data (CSD) is used to develop a technology for creation and update of cartographic materials, to develop software for processing of spatial data, to coordinate the requirements to the content and quality of data while the map materials update.


Coding system in CSD ensures transformation of the meaning given to the classifier object into the respective unique code designation. The coding method for classifier objects relies upon the hierarchic method of classification with sequential coding method.


Digital conventional topographic symbols for development of electronic maps and plans are made in the graphic editor environment of geoinformation technologies by Bentley Systems, Inc. (MicroStation, Geographics, PowerMap, BentleyView). Libraries of conventional symbols are developed for the scales of 1:10 000, 1:2 000, 1:1 000 and 1:500. There are the sections that describe:


  • topographic conventional symbols (in accordance with the domestic regulations regarding the map-making products);
  • special symbols to depict the objects of pipeline transport systems (as stipulated with the industry standards);
  • special symbols to describe land cadastral situation.

Libraries of symbols are realized as resource files of graphic editors of the technology by Bentley Systems, Inc. and feature convenient user interfaces for automated use while development of digital topographic maps and plans.
