Can I view the charts with an imaging program (eg: Photoshop)?
The C-MAP demo charts can only be viewed within the SOB program. They are not image files as such (not like Photoshop or jpeg etc). They are special data files which, when opened by SOB will be correctly drawn to represent geographical shapes and navigational information. It sounds like, on your computer, that Explorer just “coincidently” thinks they are Kodak image files. They are not similar to ANY image file formats, nor compatible with ANY image display software. The only way to “view” these files is by placing them in SOB’s DemoCharts folder and running SOB. Any C-MAP charts found (demo or licensed) when SOB starts will be shown on the world background as grey squares which can be “zoomed” into with SOB’s toolbar buttons or the mouse wheel.
