GeoTexture Specifications
Side Scan Sonar Image Processing, Mosaicing, Texture Mapping and Classification Software

GeoTexture is a unique software package from GeoAcoustics for analysis of side scan sonar images. Side scan sonar image files may be loaded, processed and mosaiced, and multiple image files may be loaded for bulk processing.

GeoTexture has a powerful suite of tools for normalising the side scan sonar image texture across the swath, which significantly improves the image quality for both human and machine interpretation. It can also be trained to remember and recognise multiple textures across and between images, and output classified maps. This makes GeoTexture an invaluable tool for interpreting sonar images of the seabed environment for applications ranging from civil engineering site survey to biological habitat mapping.

As well as standard side scan and image data formats, GeoTexture can also read the side scan output files from the GeoSwath Plus shallow water bathymetric sonar, offering significant benefits to existing GeoSwath users in side scan normalisation, image creation, and texture mapping.

Operating System:	Windows™ XP PC.
Resolution:	User definable (both for loaded side scan data and mosaic generation).
Side Scan Processing:	Bottom detect, bathymetry filter, beampattern extraction, normalisation, slant range correction, 1D and 2D filters, mosaic generation.
Normalisation Methods:	Range, grazing angle, beampattern, transducer motion, seafloor slope.
Classification Methods:	Image based with user defined box sizes for supervised training.
Input Data Formats:	.jpeg, .bmp, .tif, .png, .tga, .pcx, .psd, .xtf, .mod, .mof, and GeoSwath .swp.
Output Data Formats:	Data image, classified image and characterised textures as .jpeg, .bmp, .tif, .png, .tga, .pcx, .psd, .xtf, .mod, .wmf, and GeoSwath .mof.
