Well, I'm trying to advance in several directions but I think I'll focus first on scenario creation and I'm wondering how to collect information to solve other three subjects:1. Developing scenery for Rio de Janeiro Brazil, I found an interresting problem. The runways are half length over the water and planes can not go through taxiways in these areas. The plane sinks. So how can I correct the terrain around the airport creating land below the airport?2. There is a lot of mountains and hills around Rio de Janeiro, P

JJ,This recent thread covers the entire "coastline/runway/taxiway" issue: http://ftp.avsim.com/cgi-bin/dcforum/dcboa...rum=DCForumID19Download Colin's TerraShape program and use it with TerraScene to resolve your land/water/taxiway issues.For elevations, you should probably download GTOPO30 data - it is available from USGS and other sites. Converters are available from Asrux and the Avsim Fly! file library to prepare and import the elevation data into Fly!If there are other flattening issues, download the Flattenator program (advanced version) - there is some info on this in the FAQ area of the General Forum.

Many thanks Randall___ JJLobo ___55 11 37268158
