Hello,
I have a problem with weather routing.
My routing goes through land !
If I check collision detection, I hav ean error : " Not pf1bit (C:\dpr32\NAV\vrtool\LandCollisionDetector.pas, line 58)"

any idea ?

Land collision detection bitmap must be a monochromatic
windows bitmap (*.bmp) with 1 bit per pixel
(like the one distributed with vrtool).
If the bitmap is in another format, it will fail.
