Hello Artem,

srtm2shp easting northing scale width height interval shpOut extendFactor

easting, northing are in BNG.
scale is pixels/km.
width and height are in pixels, these are to work out the area to create in 
the shapefile. It's done this way as the code also generates PNGs.
interval is contour interval (ft)
shpOut - output shapefile, obviously :-)
extendFactor - factor to extend the defined area (so that segments which 
extend out of the defined area can be included). I used 0.25.
