Data Import and Export

SPRING allows some formats for import/export data making easier the information exchange with other software. For vector data (thematic, cadastral, numeric and network) SPRING imports and exports the following formats: ASCII, ARC/INFO, DXF and DWG, besides rectangular grids in ASCII and ARC/INFO.

SPRING imports GRB, TIFF, RAW and SITIM image formats but only exports TIFF and RAW images. ASCII and SGI texts can be imported for an existent Infolayer. ASCII and CSV tables and texts can be imported and exported.

SPRING only imports projects edited on SGI-INPE software.


The table below summarizes the available functions for data import (I) and export (E):

* Only imports and exports entities (points and lines). The object and classes identification is not dealt for DXF/DWG format.


The imported data to be used in SPRING must be equivalent (projection and e bounding box) to information layers and categories of a project in an active database. The following requirements must be fulfilled beforehand:

  • Initially determine the types of existing data to make the right association between available data and existent categories (or to be created in SPRING);
  • Verify if the user is allowed to access the files for import/export in the correspondent directory;
  • Create or Load the Project in the active Database;
  • Define the database categories according to the data to be imported based on the conceptual structure of the active database;
  • The data to be imported can be inside the bounding box of an active project or the project can be created during the import of data;
  • Verify the data unit and/or resolution;
  • The data can be stored in an existing IL (mosaic operation) or the IL can be created during the import.
