----------------------------Original message---------------------------- Re: Scaling-up maps for murals and 3D models: I am looking for a short list of books (Title, Author, Publisher, ISBN - or - Title, Author, Call code) describing techniques which will help two of my customers contemplating the following projects. Project A) Draw an environmental map mural approx size 8 x 8 ft of the Bay of Fundy and Gulf of Maine (northern part) - approx 360 x 360 miles - showing rivers, major streams, etc., with contour lines (topographic & hydrographic), using topographic maps (1:50 000, 1:250 000) and nautical charts (1:50 000, 1:200 000, 1:300 000, and 1:1 000 000). Project B) Build a 3D plywood/papiermache(?) model (size unknown) of the Magaguadavic River, New Brunswick, watershed - approx 20 x 60 miles - using 1:50 000 or 1:250 000 topographic maps. With thanks. ------------------------------------------------------ Nick Wainman-Wood Blue Peter Nautical Books & Charts P O Box 250, St Andrews, New Brunswick, Canada E0G 2X0 E-Mail: [log in to unmask]
