EDIT : Looking at another file, it seems I can append as hoped. But would I be right in thinking that the roughness lines need to be fixed width (Tab delimited seems to work for the elevation lines)? Thanks

Hi, I have some existing code that successfully writes .map files. At present however it only writes the elevation contours. I have added code to append roughness lines to this file. But the result does not work. I am fairly sure that the format for my roughness lines matches that set out in the helpfile (see below). So can I append roughness line to a .Map with elevation data or must the entire file be in the format : z01 z02 Z n Thanks Neil EXAMPLE OF ROUGNESS DATA 0.05 0.375 11 1426320.9785 6308074.9936 1426220.9785 6308074.9936 1426220.9785 6308174.9936 1426170.9785 6308174.9936 1426220.9785 6308174.9936 1426220.9785 6308274.9936 1426370.9785 6308274.9936 1426370.9785 6308224.9936 1426420.9785 6308224.9936 1426420.9785 6308074.9936

Hi, Thanks for the reply. I am looking for a solution which is easy to automate so I was wondering if I couldn't instead use contour lines? If I convert the landcover to a raster and create contour lines that are for specific roughness class changes only, then two adjacent landcovers with ver different roughness classes will simply squeeze the intervening contour lines very close together. I can then consistently set the Right as the higher value and left as the lower value either side of any given Roughness line? Neil

Hello, I am just getting to know WASP and am trying to export a polygon shape file to the required format. I have read on the forum that there are other programs in which this can be done but ArcGIS is what we have and I have inherited a script to make the conversion which I need to debug. My question is this : When I convert from polygons to lines should I do so for each polygon seperately (thus there will be duplicate lines for common edges) or use only one common edge? If the latter there will be situations where the decision "left or right" will be contradictory for common boundaries. Thanks in advance, Neil
