Thanks Tore That certainly looks very interesting! Does the software allow you to export to a geotiff format for use in a GIS environment (eg ARCGIS or ARCView?? Brad Hi Brad, Please let me know if you would like to get a license for SonarTRX. You can also send sample sonar recordings, if you prefer to see sample output from the program. (The resulting raster images imports fine into ESRI products.) support@sonartrx.com http://www.sonartrx.com

Hi Brad, SonarTRX-SI currently saves to PNG or Tiff (not geotiff), but will produce a world file and prj file for each image. A generated png image tile would include the image file itself and optional coordinate system/projection files: image.png ----if prj/world file option is turned on: image.pgw image.prj ----if Manifold GIS coordinate system option is turned on: image.xml ----if Fugawi ENC option is turned on: image.jpr The ellipsoid is WGS-84, and there are two projection options: - Local Transverse Mercator for each image tile (i.e. The world file is in meters relative to a reference point on the tile, as defined in the prj file's projection) - Geodetic (i.e. The world file is in degrees, relative to 0 deg. North, 0 deg. East) I hope this helps. Best Regards, Tore tore@sonartrx.com www.sonartrx.com

Hi Brad, SonarTRX and SonarTRX-SI are two software products that generates geo-referenced images from sonar files. World files and prj files are generated for each image tile, so they can be imported. - SonarTRX-SI supports Humminbird Side Imaging (SI) sonars. - SonarTRX supports Humminbird and other sonar file formats such as XTF(, including Lowrance XTF), and Imagenex (Yellowfin & SportScan) If you do a Google search for "SonarTRX kayak" you should find many links to an article and a YouTube video written by a British user. There is also an Australian user who wrote about it on the hobiecat forum: http://www.hobiecat.com/forums/viewtopic.php?f=71&t=33777 For anyone interested in this, please get in touch, and I can send sample images. Best Regards, Tore Email: tore@SonarTRX.com Web: www.sonartrx.com
