DIGITAL CARTOGRAPHY

ISTRAM has its own graphics environment. One of the assumptions with which it was developed was to offer a powerful graphics environment, with the typical edition tools of a CAD as well as functions specifically designed to process the Z coordinate of all entities. What is more, you will always be working in 3D.

To print plans you just need to know what paper you will be using, sort out the sheets and send them directly to the physical or virtual printing devices (for example, PDF printing) and devote the rest of your time to other more important processes. You can also customise boxes or stamps to show titles, subtitles or page numbers quickly and easily.

Forget about renumbering plans manually, or needing a whole team of draughtsmen to help you deliver plans. For most functions or work areas that generate graphic information we have taken into account the freedom you wish to work with, allowing you to deliver plans with outstanding quality.

Unfortunately we do not always have perfect starting data. ISTRAM offers a full set of tools specifically designed to successfully address the difficult task of preparing accurate and correct cartography.

Our powerful system of layers and models allows organising information in a way that facilitates selecting the entities to be fixed. We also provide analysis functions that filter, select, change, move or rotate elements. Some of these functions are specific to process the Z coordinate.

A set of level curves with/without spot height is fixed, including spot height labels or specific symbols, very quickly and easily. Also, by using a specific 3D connection or snap, you can enrich data creating new entities supported directly on the field.

ISTRAM offers a versatile system that allows modifying the systems your cartography is based on, changing ellipsoid, changing lune or projection system. This way, you need not worry about having to use external conversion tools or not being able to use data.

If the entities are not in the right location, you can use the coordinate transformation tool including all possible actions necessary to place the information in the correct position: movement, rotation, scale or Helmert transformation.

ISTRAM has a powerful system that allows importing and exporting data to/from the most common CAD applications such as Autocad or Microstation You can also use a correspondence dictionary that guarantees the data will be viewed using the same type of layers or entities and with the codes associated to types. A level curve at origin is a level curve at destination.

You can use topographic control or uplifting data taken on the field with total posts or GPS devices. These will be processed and translated by numerous conversion programmes. If for any reason format is not contemplated, our development department will quickly programme the necessary application.

Both at vectorial and raster levels, ISTRAM has an internal data format that allows moving large quantities of information without any blockage, hourglass or flickering. The dynamic zoom or movement functions, 3D viewing or geometric analyses are conducted with exceptional speed.

ISTRAM has tools that allow sectoring the information and saving it in separate files that can later be uploaded by a file manager and area that optimise resources and upload information only when necessary. At an even higher level, it has a cartographic database manager that can handle information at various tiers. Some public bodies have organised their cartographic data system using this tool.

With ISTRAM you can generate digital land models using topographic upliftings or vectorial data of diverse origin. The application is especially programmed to correctly process point clouds and rupture lines that usually define a surface. The generation of triangle models (TIN) is done very quickly and the process to generate level curves is very efficient.

The programme power allows working with large files covering an extension of several km2 easily, also taking into account data isles and using external boundaries designed by you to limit the 2D space to be triangulated.

The models generated can be used in other ISTRAM sections, that is why we offer the possibility of saving them in a special format, specific for other programme functions to be able to conduct a rapid analysis and processing, thus generating various types of data: surface intersections, gradient and hypsometry, levelling and bank volumes, visual basins, flood plains, raft construction, etc.

Whether it is a tachymeter or transversal profile measurements, ISTRAM offers tools to communicate with multiple topographic posts and GPS devices. Files translated into internal ISTRAM formats can be immediately edited for viewing and correction, or used to monitor the construction status of your project.

You can obtain surface and volume measurements of levelling and banks immediately, generating plans and reports to help you back up your data very easily. Unlike other applications, ISTRAM’s profile editor has over 30 utilities addressing all the possible issues that may arise: whether you need to cut out a surface over another one, get an intersection between two lines, etc.

The “electronic notepad” function is an application that allows conducting the most common topographic operations: network compensation, transformations, etc. and it also takes into account the possibility of changing georeference and projection systems at any time. It is usual in the case of tachymeters to code certain points or lines on the field. This peculiarity is completely included in ISTRAM, releasing the surveyor from this tedious task.

PROJECTS FOR LINEAR CIVIL WORKS

You have probably already heard about us. Our client satisfaction is our best promotion. Our application allows controlling all design and construction processes for any type of civil works.

Our programme solves all the project manager?s needs. ISTRAM is not an application that depends on a commercial CAD to which certain tools have been added. We are backed by 27-years? experience, during which we have participated in the construction of large civil engineering infrastructures in Spain and abroad.

All the elements you need to manage in your project are taken into account: the starting cartography, the design of ground plan axes, elevation and cross-section, measurements, plans and lists that need to be delivered to the client and all the files involved in the building process. Unlike other programmes, ISTRAM is not a generic CAD to which certain functions have been added.

With ISTRAM you can define from a simple rural road to a motorway with the most complicated section commissioned. The simple work plan is always the same and is always visible. There is no need to drop down complicated menus or sub-menus to add or check whether certain data are automated.

The dialogue boxes integrate buttons, text boxes and tabs that allow defining each part of the ground plan, gradient and cross-section, to which you can access in a logical manner, and where you can automate from the simplest design to the most complicated one.

ISTRAM’s main philosophy is to offer users freedom and flexibility, not forcing them to define every element before they can continue.

In various parts of the application you can define parametric or vectorial section elements, allowing the latter to define any type of cross-section: kerbs, slopes, median strips, sidewalks, etc., can have any shape or layout.

When the project’s singularity requires designing elements that change shape or size according to the land altitude, unlike other programmes, ISTRAM provides functions that allow applying different types of sections unattended. A small example is shown with a file of wall sizes that the programme selects automatically from a list prepared by you.

ISTRAM allows flexibly defining the various parts of a cross-section (pack of road surfaces, ground selected, over-excavations, finish of kerbs and under slope) offering users data input to define where and how each surface is to be built, since not all projects are the same.

ISTRAM offers functionalities that allow defining connection relations between axes. This task is dreaded by tracing technicians since they know that with other programmes they must spend a lot of time defining, adjusting, calculating and checking.

Process automation is included in many parts of the application, meeting the needs expressed by many clients. The project is contemplated as a whole by ISTRAM and not singly axis by axis, thus allowing generation of a full link in a few minutes.

The project organisation can be conducted to the extent of defining for each axis the mode of calculation, the group it belongs to and the way it is measured and drafted. This flexible structure allows users to define several scopes and thus try different building solutions.

When delivering results, usually more hours are spent than initially planned because certain elements need to be finished off with other CAD applications. With ISTRAM you can really automate graphic output, dramatically reducing the time and resources usually spent on these tasks.

The system covers all the usual areas present in a civil engineering project and unlike other applications, you can entirely customise the type of plan to be generated. Forget about presenting poor results or needing a team of draughtsmen to finish off the plans.

You can share results with other work teams, to which you can deliver information paged in CAD format, in order to integrate it immediately in the project’s general plan. Virtual printing devices allow you to choose the language ( CAD, PDF, SVG ) for generating digital information.

Linear, surface and volume measurements that can be generated with ISTRAM are prepared with a system that analyses and processes the sections designed to offer the same results regardless of the layers or surfaces created. You don’t need a different measurement style for each axis, although if you wish, you can define and apply your own.

The measurement tables or drawing style files are continuously adapted to the new functionalities programmed by the development department, allowing you to continue working with no need to change, migrate or transform data between versions.

The data lists and files are generated at the same time that the geometry is calculated. This ensures they always reflect and include all last-minute changes. Forget about having to review temporary file correspondence.

During design or review the need arises to apply or verify geometric standards included in the tracing regulations. ISTRAM takes this functionality into account and offers the possibility of using design tables, that always offer the most appropriate and precise value needed at any given time.

Modern road safety audits can benefit from the reports and plans prepared with ISTRAM which outline the various “irregularities” of a route, notifying of radiuses or clothoids outside the recommended or mandatory range, or incorrectly defined cambers.

Some of ISTRAM’s tools and complements allow generating speed diagrams, visibility studies or vehicle trajectory plans, thus offering value added instruments that increase the quality of your work and support your design in front of your clients.

ISTRAM has a free structure that allows saving the definition of any type of linear work, regardless of its functionality: roads, motorways, railways, pipelines, channels, etc. ISTRAM takes into account the singularities of each one and organises them in order to house them under the same working system, without modifying the environment.

Data use and result generation is the same for all types of projects, with the possibility of using templates or customised drawing modes, considering the singularities of each element: sleepers and railway tracks, sanitation and supply pipes, road and motorway surface packs, etc.

Your work team will be more profitable as you will be able to face different types of jobs. The companies that use ISTRAM are cross-functional, they address any type of project, quickly obtaining a return on the investment they made when buying the application. Besides, the continuous application of upgrades and new functionalities are a guarantee for your business.

The building peculiarities of projects affecting existing roads or railways duplicating their capacity have always been approached warily, given the huge number of geometric possibilities to be resolved.

With most programmes it is impossible. However, ISTRAM has solved this problem by offering dialogue boxes in which users can easily define the actions to be carried out: cutting, demolition, clean up of banks, complete excavation… The programme performs these instructions immediately, it can review the actions conducted at each pk and correct it if it is not as expected.

ISTRAM also offers the possibility of using data defining current layout to define a new layout optimally, making the most of the current road surface and always using, whenever possible, the existing camber, minimising action costs.

The design of any type of construction with ISTRAM includes the tunnel and false tunnel section, offering simple dialogue boxes to define parameters or vectors of all surfaces comprising the vault and counter-vault, or excavation or filling in the case of false tunnels.

Each part of the tunnel has the possibility of defining the excavation and several levels of lining. Each one of the elements defined is handled in the same way as a regular road, the system is 100% compatible, it is not a different application. The lists of geometries and measurements are obtained in the same way a simple road is defined.

Logically, the design of tunnels for underground railways is one of the areas that most benefit from ISTRAM. Many projects in Spain and abroad are optimally designed, benefiting as well from the follow-up and monitoring module, where the differences between that projected and that built are analysed and solved.

The design phase certainly, but in the end, the most important aspect could be the generation of lists and reports that allow you to defend a budget before your clients. ISTRAM offers the necessary tools so that this task is not just a functionality but rather an essential part of the programme.

Lists on land movements, the various layers of the road surface pack, the surfaces of slopes to be replanted, the linear meters of kerb, the kilos of steel and concrete, etc., are taken into account by a system which defines the work units and unit prices, conveniently appearing in fully customised reports.

The programme’s versatility allows any type of hierarchical grouping necessary: according to the axes or groups of axes of your project, by building elements, by phases or dates, by contractors, etc. The reports generated allow you to easily manage the construction process.

As an ISTRAM user you have no problems addressing other types of projects not related to roads or motorways. The design environment and working philosophy is still the same, providing the necessary tools to design a railway project.

The definition of the track apparatus that connect the axis on the ground plan and the definition of the shape layer, ground selected, ballast, sleeper and track are covered by the application, generating the project transversal profile files using the same data structure and therefore guaranteeing that all ISTRAM tools can be used regardless of the type of project.

Naturally, the geometric singularities regarding ground plan layout, elevation and cambers are covered by the application providing design tables that allow adapting to the track geometry defined by the railway authorities.

ISTRAM users need not change application to design pipe layout projects. They just press a key to decide the type of project associated to each axis. This covers in this field the design requirements that allow defining any type of ditch, pipe or covering.

Naturally, the application considers the need to do certain hydraulic calculations that allow engineers to properly size the pipe stretches or use prefabricated elements and typical accessories placed on specific points of the layout.

The measurements and reports obtained are a competitive advantage over other applications that are too specific or focused on mere hydraulic calculations. In the end, you need to present a construction project that is similar to the one required for roads or railways.

The geometric and building connections of the streets of a development are solved by ISTRAM quickly and easily, immediately providing a built solution according to the radius defined. In just a few seconds you can view results, delete them, try with another radius?

Geometry measurements and lists are obtained instantly and are part of your project’s report. There is no need to add any files manually. The whole project calculation and the possibility of organising axes by groups is ideal for the usual sectoring in this type of projects.

Changes on the land surface or ground plan geometry or crossing axis elevation can be immediately recalculated, since ISTRAM automatically finds and defines the necessary curve. Afterwards you can use all the definition lists created automatically and which always include the data of the latest definition.

This does not happen with ISTRAM. From the start you are always certain you are showing the lists corresponding to the latest changes, thus avoiding last-minute surprises when the project is delivered to your client.

However this philosophy is free. If you want to be able to generate a list of geometries or measurements at any time that allow you to assess an alternative, as with any programme, you can always choose where to save your data and ISPOL offers a new system that allows saving project versions easily.

Our project manager is based on a system that allows associating geometric definitions for each axis that are saved in separate files, which allows checking, sometimes at a glance, the information being used every time.

Sometimes land geology where a project is to be designed defines certain geotechnical horizons that need to be taken into account for construction. ISTRAM allows defining several surfaces with which the programme interacts geometrically.

Our application takes into account that levelled slopes and selected materials may be different depending on the type of land, and that in land ? rock contacts it may necessary to define another type of geometry.

Volume measurements benefit especially from this functionality. The various strata of materials are measured easily, allowing your budget to best reflect the real construction situation.

During the construction process, ISTRAM is a valuable working tool that facilitates the tasks of geometric control and provides all the necessary information to bill or evaluate the cost of the work conducted.

Both in the case of normal surfaces corresponding to a normal levelled area as well as tunnel excavations, ISTRAM offers tools that allow you to see the differences between that projected and that built in order to take the pertinent measures.

Monthly measurements are managed by the programme, which also considers that some elements can have different units or are not expressed by exact geometry, in other words, our programme considers that your project can be measured by topographic means, by production, square, cubic or linear meters, tons or money on account.
