Import/export

ScanEx NeRIS uses its own raster data format - an STI format (*.sti). Up to 36 spectral and thematic channels can be stored in this format, having 8-bit (0-255) radiometric resolution; the program uses 4-bit floating-point layers for internal calculation. All layers (both source data and the processing results) have the same size and are stored in one file, which can be imported or exported by the program.

ScanEx NeRIS also offers the import of raster layers in the following formats: PGM/PPM and BMP formats, of scalar grids in the Surfer format, widely used by geologists, and of Arc/Info and ArcView grid formats (ESRI BIL (*.bil); ESRI BSQ (*.bsq), Arc INFO ASCII GRID (*.ASCII)). This enables to process not only images, but basically any information presented in the form of a scalar grid (e.g. elevation, geophysical fields, etc.). The application can import most commonly used raster data formats: Geo tiff (*.tif); ERDAS Imagine (*.img); PCI Geomatica (*.pix); ENVI (*.*); Windows Bitmap (*.bmp); JPEG file (*.jpg).

The application can export the processing results into a vector form and convert them to various GIS packages using commonly used exchange formats such as ESRI Shapefile and MapInfo MIF/MID.

ScanEx NeRIS application data can be exported into the following data formats: Geo tiff (*.tif); ERDAS Imagine (*.img); ESRI BIL (*.bil); PCI Geomatica (*.pix); ENVI (*.*); Windows Bitmap (*.bmp); Arc INFO ASCII GRID (*.ASCII);PGM (*.pgm); PPM (*.ppm).

For Geo tiff (*.tif), ESRI BIL (*.bil), Windows Bitmap (*.bmp), Arc INFO ASCII GRID (*.ASCII), PGM (*.pgm) and PPM (*.ppm) formats additional information can be saved (reference files and projection parameters) required for ESRI and MapInfo products.
