Hi all, With CoastLineMaker and Ground2k I've done several BGLs wichcover a large portion of my country.My question is: How can I link those BGLs to obtain only one working in FS2k2 ?orHow may I modify ASM files from Ground2k to link them with LinkCLM ?ThankYou

Hi clogi.I don't believe you can merge the TDF-type BGLs. You can hack the ASM files, to combine LWM, or VTP lines, or VTP polys together with others of their type. I actually did this with PEIfix, which corrected the LWM masking for Prince Edward Island. It was a large area, that I split into LOD8 sized projects for Ground2K... I saved and renamed the asm files for the watermasking, and combined them for final compilation. The ordering of the Areas and Cells is critical for combining LWM code... not an easy task.A project can have dozens, if not hundreds of BGLS in it's "scenery" folder. It's not necessary to combine the BGLs at all. It just makes a project tidy, and in your case, may be unnecessary.Dick
