Geoinformation system on work with spatial and graphical data_

GIS is an automated geographic information system for collection, storage, analysis and graphical visualization of spatial and its associated graphic and technical data. The system implements a powerful set of tools and functional properties after processing of different types and different scales of mapping resources, remote sensing data, materials, specialized graphics passport information and constructs oil and gas facilities, the space described in the database system of GIS.

The subsystem of work with spatial and graphic materials may contain the following specialized modules:

Spatial data management

The system provides a user with a fully-functional interactive map-making basis with the geo-coded process facilities, auxiliary systems and the surrounding facilities available. Interactivity of all map-making materials involves convenient navigation tools, and connection of all graphic items with the data sheet and operational information. This allows for search and localization of the selected process facilities on the maps, thus increasing the interactive perception and demonstrativeness of the technical data sheets.

Beside the standard tools for navigation and map-making materials management, this system features the functions allowing to select the mode of map-making basis display (topographic map, materials of aerial or space surveys, combined or thematic map, as well as the resources of such Internet services as Google Maps, Bing Maps, Yandex), to manage layer-by-layer display of objects, functions of the distance and area measurement, export to PDF, simple and combined printing, other.

Functional possibilities of the system while handling the spatial data:

Adjustable management of loading and display of objects on map-making and graphic materials according to the categories and groups.
Search and visualization of process facilities and equipment on electronic maps and graphic materials (lighting, localization, centering in a separate window).
Dynamic display and adding of process facilities with a reference to the pipeline axis and the locality onto the map.
Localization of the objects from the related modules.
Transition to the object on other graphic materials.
Display of brief technical and data sheet information of the selected object.
Search and localization of objects (according to attributes, semantics, coordinates, mileage, cadaster number, selected area).
Automated route location and determination of optimal driveways to the specified point on the map, calculation of the arrival terms (considering the season, vehicle type, remoteness of the object from the service stations etc.).
Placing a tag to the point on a map with a possibility to add comments and photos.
Three-dimensional representation of line pipe sections.
Export of a map fragment to various bitmapped formats (PNG, JPG).
Export of a map fragment to PDF (for further printing) with a possibility to adjust the scale, sheet parameters, framework design.
Display of thematic layers which visualize the inquiry results, using various attributive and spatial criteria (display of spatial data from unrelated modules under the specified display settings).

Working with the technological graphics

Technological graphics includes all types of diagrams used in the course of designing, construction, operation and repair of any objects being a part of process facilities: process diagrams, flow charts, plant layouts, automation diagrams, connection diagrams and others, which may be represented in GIS both in bitmapped and vector formats – divided by layers, with the possibilities of interactivity and object localization on a map.

To handle the technological graphics, a range of tools is provided for interactive review of various process and other diagrams linked to the object data sheets. The implemented functional allows for search for the items, for their localization, display of the object data sheet characteristics and navigation transitions to cartographic resources across process facilities.

Technological diagrams of the production complexes, process systems and apparatus may include an integrated range of data from various categories and groups. Such groups correspond to layer-by-layer representation of objects and systems, and are managed with the layer-by-layer display of objects.

For handling the interactive graphic diagrams in GIS, standard options for graphic materials are used: searching, viewing, editing, and printing. Beside the standard options for graphic materials, the interactive diagrams support the function of making a reference to the data sheets for the objects placed on the diagrams and obtainment of their technical and operational characteristics. Similarly, such object may be referenced and visualized on the technological diagram from the object data sheet using lighting, object localization or centering in a separate window.

Interactivity of all graphic materials involves convenient tools of navigation, including interconnection of all graphic and spatial materials, as well as reference with the data sheet and diagnostic information, possibilities to develop individual graphic diagrams based on multiple-factor selection of the pipeline objects.

Construction of the linear objects single-line diagrams

With single-line diagrams, an unlimited number of various characteristics of the pipeline may be visualized: longitudinal profile, current situation, assembling properties of the pipeline, means of the cathodic protection system, any defects revealed, results of the defects estimation, data of the part electrometry (defects of insulation, soil resistivity, potential measured), control instrumentation readings, and many others.

If database includes of relevant data, the system allows you to create single-line diagram for the following values:

situation – describes situation along the pipeline;
pipeline – describes location and marks of technological objects along the MGP;
cathodic protection objects – describes location and reference marks of cathodic protection objects;
pipe journal – describes the distribution of pipeline by welds;
metal defects – describes revealed defects by PIG inspection results;
profile – describes the pipeline ground position (in axial presentation);
TS seasonal measurements – describes the results of measurements of the potentials on the MGP;
detailed electrometric measurements – describes the results of electrometric measurements along the MGP;
corrosion situation – describes the degree of corrosion danger of MGP on the basis of soil resistivity;
soil resistivity – describes the sections of the pipeline are located in areas of high corrosion danger (HCD) and low corrosion danger (LCD);
insulation state assessment – shows the quality of the insulation coating on a selected section of gas pipeline.

Diagrams may be displayed for a given section of the pipeline and using the navigation tools to carry out their movement along a linear object with a predetermined pitch. The order of diagrams placement can be changed, including the addition and removal.

At the point of the cursor location displayed on the pipeline kilometrage, readings measurement and a list of object diagrams. Objects in the diagrams are interactive and you can move on to their passports. Available legends of diagrams.

Construction of the linear objects longitudinal profile

The system is provided with the tools intended for selection and building of a longitudinal profile of a field pipeline, which is made based on its spatial description contained in the database. This information obtained following the as-built survey of the pipelines and contains the data on its location, burial depth, crossing with any natural objects and utility lines, passing any typical vegetative areas.

Longitudinal profile has a function of interactive change of horizontal scale and zooming (detailed display) of the selected sections. All parameters of the profile building (mileage, relief height, pipeline burial depth, type of the crossed object) are displayed interactively on the profile if the pipeline picket is hovered; and it is also possible to switch to the data sheet of the crossed object.

The pipeline profile may be printed out or saved in PDF with the options of scaling (both along the horizontal, and vertical axes) and automatic calculation of the printed pages number in horizontal and in vertical directions.

Construction and visualization of data on three-dimensional models

For constructions of industrial areas, technological pipelines and plumes CS of linear part pipelines implemented functionality for constructing a three-dimensional model created on the basis of field measurements, post-processing, loading model system linked with operational and technical data about the objects of system. The complex three-dimensional model data can be included the results of survey of technical condition of the equipment (Vibrometry, thickness measurement, pitting, points by acoustic emission testing, etc..) for ease of analysis of the technical condition and visualization of comprehensive for information about the object.

For handling and analysis of spatial data, display elements control is used, i.e. navigation, thematic layers, tags, speed settings for moving along the model.

Working with a three-dimensional model allows for the object search and localization, display of bitmapped underlay, measurement of distance among the objects, switch to the object data sheets with the description of their technical and operational information.

Thematic map construction

Thematic map construction allows setting the terms of spatial objects display on the map materials. Parametric search for the objects is performed under the numeric, verbal or logic types, or date; the styles of their display on the map are set upon formation of the object selection.

Analytical functions based on attributive data of the technological objects data sheets are realized through formation of logical inquiry, which allows for making various selections of technological objects based on their attributive information or aggregation of several attributes (including operational and diagnostic). The parameters of the selected objects display may be set or modified by: color, transparency, style of line, width, symbols, boundary color. The range of parameters will differ for the objects depending on the object reference type – single-point, linear or polygonal type. Upon the selection of the display parameters, the objects selected based on the inquiry results shall be arranged on the cartographic material in the established format.

Working with land cadastral information

Data on the borders of land parcels, land users and land owners, intended use and the title documents may be displayed from the object on the map through switching to its data sheet. Cadastral information is kept and updated in the database of the information system, and may be referenced to the data sheet information of the land parcel and its plan on the map.

The system ensures the functions of navigation and management while handling the cadastral materials, i.e. displacement, scaling, switching among the map kinds, panoramic display, measuring of distances and areas, positioning on the map, as well as route location, search functions and printing out a map fragment, including printing with the marginal information.

Construction of the well section

To depict all construction elements of UGS wells and to handle their technical, diagnostic and operational characteristics conveniently, a special program module was developed. A well diagram is built automatically based on data contained in the data sheets of wells and their elements. External view of the wells (arrangement of aboveground and underground equipment) corresponds to their type (operational, control, monitoring, geophysical, injection wells).

Moreover, the diagrams are displayed in a scaled graphic proportion to their own actual metric depth characteristics. All objects on the diagram are interactive and allow for obtaining data sheets, if they are selected. Moreover, the well diagrams may be printed out and saved as PDF.

UGS hydrodynamic section construction

To build hydrodynamic section of UGS, the system is provided with a relevant program module. It enables a user to build, based on the set unlimited number of wells, the sections with a reservoir bed, a cover bed and construction elements of the wells (in particular, perforations) depicted. Distance among the wells, their height and depth characteristics which are required to build a section are selected from the well data sheets and strictly correspond to the scaled graphic constructions. Such section is interactive and allows for scaling up and down and for displaying the data sheet of a well or its perforation selected on the section.

Construction and accounting of zones impact of damaging factors on cartographic materials

GIS tools are used for constructed zones impact of damaging factors of technological equipment in case of accidents, protection zones of objects and other zones of influence, which are calculated according to accepted standards in the production, the results of which are displayed on the map as of radius of impact.

Accounting of the impact zones is used at designing and estimation of danger of exploitation of existent and new equipments, when analyzing the impact zones on adjacent objects in accidents, routine maintenance, as well as performing other production problems.

Calculating the impact zone boundaries damaging factors in accidents include:

determination of zones of possible destructions with forming of list from objects of zone of destruction,
saving of the calculated zone,
displaying information of the destruction zone at the poin of general plan.

Besides a construction and account of zones impact of damaging factors, on the cartographic materials it is possible also to visualize other affected zones on the basis of spatial data model and established calculation methodologies:

Displaying of protection zones of technological equipment;
Data on protection zones of technological installations;
Determination and displaying of zones of ecological pollution and infringements of the land;
Determination of zones of pollution and spills, and them displaying on the cartographic materials;
Displaying coverage zone of communication (pre-calculated by system side).

Comparison of project and executive documentation

With using GIS functions can be carried out analysis of results of the executive survey, its comparison with the design documentation and existent executive materials.

The system performs loading data of executive survey in the established format, that presented in a single coordinate system with the existing materials.

Materials of design, executive surveys and other spatial data can be managed and displayed in layers, when working with materials are used standard tools for working with the map: navigation, distance measurement, search and navigation tools, determination of coordinates, user notes, thematic map construction, etc.

Tracing of new communications (underground or on the overpass)

In order to automate design tasks function of laying communications for underground pipelines or communications on trestles was developed.

Communication tracing module displays designed route in the plan (applied to the plan by the user in manual mode to control the location of surrounding objects), captures the depth of laying communication relative to the ground mark the location and depth of intersected underground structures and communications, their metric and technological characteristics.

When working with the module of tracing communication, the following functions are carried out:

Loading a fragment of the general plan including the spatial information about objects in displayed area;
Manual planned creation of communication's passing between the set points with the indication of points of insert and intermediate control points;
Entering the basic depth of the projected underground communication and planned clearance between the crossed communications;
Сalculation of the mutual arrangement of the nearby underground engineering structures and communications, their intersections according to their technical characteristics and the data formation on conflicts and extends beyond the tolerances in the clearance;
Display of the spatial position and the list of objects at the cursor location;
Transition to technical and passport information of the general plan object;
Printing the section of passing underground communications.

Editing of graphic materials

Development of new diagrams, editing of existing diagrams, binding of diagrams and individual graphic elements with the data sheets of process facilities may be performed with the process graphics editor implemented in Microsoft Visio environment. Changes may be made using Microsoft Visio tools with a library of conventional symbols created in GIS to support the object display, as well as with the function of referencing the process diagram elements with the object data sheet information.

When diagrams are developed, they are referenced to other graphic and cartographic materials with a possibility of further navigation among such graphic data.

Editing of cartographic materials and relocation of the pipeline route

Administration of spatial data includes the tasks of tool support of modifications to cartographic materials, relocation of the pipeline route, adding of technological objects to the map and their referencing with the data sheets.

Editing of topographic objects and modification of a situation on a topographic map, updating of bitmapped materials (data of remote probing and other resources) are realized with the tools of GIS platform (Esri – ArcGIS).

To modify the spatial location of long-distance linear objects (pipeline route), «Geodesy Editor» module is implemented, which enables for entering geodesic data on location of the pipe and the pipe-related objects to the database in the automated mode. Data on the pipe location may be entered to the system for the first or for the second time, in case the pipe is reburied while reconstruction based on the data of last surveys; they may be also deleted from the base or exported to external formats. The imported data on spatial location of the pipeline also contain the information on location of the process facilities and the surrounding objects, based on which data sheets referenced to such objects are generated in the database. Based on the results of geodesic data import, a pipeline is built dynamically on the map, together with the process facilities related to it, and the surrounding objects; and the data sheets of such objects are generated with primary content or – in case of re-import – updated in terms of their reference to such objects.

New technological objects may be added to the map, and spatial location of the existing ones may be edited through description of a spatial reference of the facility using coordinates or the facility reference to the pipeline.

Cadastral information import

To keep the cadastral database on land parcel location and their legal status updated, the system has a function allowing to import cadastral data, which are represented – as a rule – as an external geoinformation resource.

Desktop application of the system has a special module for automated conversion and analysis of cadastral data obtained from external organizations or governmental institutions as a linear (or polygonal) cover of the battery limits and a point cover of the area centroids on the specified territory.

Such data are imported to the system automatically using the algorithms for comparison of user data table codes with the updated land cadastral data.

After the import of cadastral information, general information is displayed with actual geometry and numeration of cadastral parcels, as well as the related layer-by-layer thematic information which represents various aspects of cadastral parcels and their owners.

Arrangement of information generated upon the import of cadastre data allows for spatial analysis performed through retrieval of thematic information about a cadastral parcel, automated selection and listing the plots according to their spatial signs.
