  • Operacional Systems: Windows (95/98/NT/ME/2000/XP/Vista) and Linux    Download Page
Version 5.1 - News and Improvements
  • Drawings
The SPRING 5.1 drawing module was fully reworked, now when a representation is selected in the control panel, it is drawn automatically instead of waiting to the user to click on Draw button.

In order to SPRING 5.1 be a system capable of faster redrawing, we use, in this new version, computational techniques to store previously drawn representation and representation drawing parallelization. In other words, it uses a new methodology where each plan is drawn in distinct proccess, using more resources avaiable on the machine..

Futhermore, to make it even faster, some layer drawings are kept in memory being avaible to immediate layer redrawing.

Besides the new drawing module, there's a new button in SPRING 5.1 toolbar, this new buttom is the Zoom Cursor.

The Zoom Cursor has the following behavior:

  • After selecting in area, it's drawn right away with more zoom;
  • Or double clicking on the screen redraws the scene, with more zoom and centralized on the clicked point;
  • Windows
Aiming to be improve SPRING 5.1 user experience, some windows have been fully changed. With these changes, tasks associated with these windows can be acomplished in a easier and more intuitive way.

The following SPRING 5.1 windows have been reworked:

  • Data Model
  • Object and Non Spatial
  • Setting Visual Parameters
  • Settings for Text Visualization
  • Import
  • Export
  • Object Edition
  • Table Linking
  • Data Formats
To make SPRING 5.1 even more compatible with third party products, it's now to possible to export and import data in new formats. This allows better interoperation between SPRING 5.1 and other applications.

The following new vectorial formats are supported:

  • DXF and DWG, AutoCAD's native format. This allow better interoperation with CAD products.
  • KML, supporting exporting and importing data to/from Google Earth.

The following new matrix formats are supported:

  • JPEG2000, is a high definition image compression standard, allowing compressions rate as high as 90% without losing image quality.
  • Color Mapping
SPRING 5.1 has new capabilities in the exibition of monochromatic and numerical images.
Now, SPRING 5.1 shows this kind of information through a Color Map, ie., it allows the user to associate a color gradient to monochromatic and numerical images, and image values will be shown in colors instead of gray scale.

This new SPRING 5.1 feature Color Map comes with a big set of predefined gradients, and allows user defined ones.

Besides being able to select a color gradient, a user can define a variation interval, where color attribution is done in a linear way.

  • Wizards
With the trend to make data importation and exportation operations easier, started by the CBENS Wizard, new Wizards have been added to SPRING 5.1.

Destacamos os seguintes assistentes adicionados ao SPRING 5.1:

  • Datum Management
    Datum Mangement is a fundamental tool when user data is not in a Earth Model dispoible on SPRING 5.1.
    Now, new Datuns can be inserted in the system.
    This operation used to be done in a manual way, editing SPRING configuration files.


  • Shapefile
    Guides the user through importing or explorting data in the Shapefile format (files with .shp extension).


  • Text Representation
    Guides the user through importing or explorting text data in ASCII-SPR, DXF or DWG formats.
  • Tables

Guides the user through importing or explorting text data in ASCII-SPR, DBF or SPACESTAT formats.

  • Multi Users
With the objective to facilitate the use of SPRING 5.1 in corporate environments, where exists a data flux hierarchy, in which certain users have different roles (Creation, Publication, Organization and Data Visualization roles) in a same database. SPRING 5.1 now allows databases with Multiuser capabilities.

Now many users with different profiles can access simultaneously a same database.

Besides simultaneous access, the support of multiuser database methodologies created a few new concepts in SPRING 5.1:

  • Workgroups, defines a set of permissions a certain group of users will have.
  • Users, identify persons responsible for a database.
  • Sessions, identify a operation being executed by a know user on a info layer.

Multiuser database capabilities are supported by some database drivers, such as Oracle, PostgreSQL and MySQL.
Obs: Multiuser in advanced testing.

  • Validation
A Validation Module has been added to SPRING 5.1 both for grids and images, generating graphics and statistical reports, asserting a layer quality through a reference layer.

O Validation Module may be split in two different tasks:

  • Grid Validation
    O SPRING 5.1 informs the quality of a numeric grid through sample points ou another numerical grid as a reference.
    Numerical grid quality is show through the following graphics: Spatial Error Diagram, Error Histogram and Reference X Estimated and through a statistical report.


  • Image Validation
    SPRING 5.1 informs the quality of a thematic image through classified points or another thematic image as a reference.
    Image quality is represented through the following graphics: Error Histogram and by a statiscal report with the Kappa index.
  • GPS
A way to adquire data is through Global Positioning System (GPS) devices, a global navigation sattelite system. It's use has become widely popular in the last years.

SPRING 5.1 adquires data from a GPS device in the following ways:

  • Download information already existing in the device, such as waypoints, routes and tracks.
  • Get information in realtime.

At the moment SPRING 5.1 GPS support is limited to Garmin devices.


  • 64 Bits
Aiming to keep SPRING 5.1 compatible with new architecures and operating systems changes were made to SPRING application suite for 64-bits platforms.

With the SPRING 5.1 release for 64 bits Windows and Linux environments, the SPRING suite is able to work with more information.

There are, initially, a few restrictions on SPRING 5.1 64 bits version. We highlight the following restrictions: only some database drivers are supported, such as only MySQL on Windows and Oracle, PostgreSQL and MySQL on Linux. Also, the LEGAL programming language is not avaiable.

  • Others
Besides the previous SPRING 5.1 features, there is also the following changes:
  • Banco de Dados
    Wider support of database drivers between platforms.
    PostgreSQL is now avaible on Windows and Oracle is now avaible on Linux.


  • Turn Restrictions
    Addition of the turn restriction attribute to the network model, adding a way to stop the flow between edges.
    Turn restriction creating maybe done with the Vectorial Editing toolbar.


  • Removal of CR Buttons
    Many SPRING windows used to had a CR button without necessity.
    Now, after editing a text field you have the same effect, validating the input, by pressing enter ou clicking on other window element.


  • Tables with multiple links
    O SPRING used to limit an object table to be linked with only one non spatial table.
    SPRING 5.1 allows multiple links between attributes of object tables and non spatial tables.
  • SPRING Community
Further information, news, questions, work and / or projects with the SPRING can be accessed on the official website of the SPRING in DPI of INPE available: http://www.dpi.inpe.br/spring

The Virtual Community SPRING objective the integration and assistance to users of the SPRING. The main feature of the Virtual Community is the support to users answering the questions, clarifying the doubts and directing the best conditions of use. The Virtual Community SPRING can be accessed at:http://www.k2sistemas.com.br/comunidade_spring/
