Format Conversion Software

Many standard image processing and geographic information system (GIS) software packages, such as Arc/Info, LAS, and ERDAS Imagine, provide tools for converting between different data formats. For users without ready access to such packages, a subroutine to facilitate reading and unpacking "flat" binary files in band-sequential (BSQ) format is available in both Fortran 77 and C-language versions.

Some of the most useful Arc/Info and LAS format conversion modules are listed below.

Arc/Info

Arc/Info can handle the raster-data formats of many of the more widely used geograhic information system and image processing software packages, as well as "flat" BSQ binary files. Modules include

DEMLATTICE
Convert Digital Elevation Model data from standard USGS format to Arc/Info grid format. Note: the DEM files may need reblocking before DEMLATTICE can process them.

GRIDIMAGE
Convert raster data from Arc/Info grid format to a variety of other formats.

IMAGEGRID
Convert raster data in other formats into Arc/Info grid format.

LAS

ARC2LAS
Convert from Arc/Info grid format to LAS image format.

DEM2LAS
Read USGS digital elevation model files and convert to LAS format.

ERD2LAS
Convert ERDAS74 files to LAS format.

LAS2ARC
Convert LAS image data to Arc/Info grid format.

LAS2ERD
Convert LAS image data to ERDAS74 format.

TRANSLAS
Convert between LAS and BSQ image formats.
