Re: AW: Problem with creation of SpatialIndex(ssx) file for Shape fil e co ntaining Polyline/Arc shapetypes

Well, the files are the same size, so that's good. My guess is that
they (the conversion code) are not writing out offset locations of the
shape graphics in the correct endian order - that's why the openmap code
seeks to an offset to read in the first graphic and doesn't find values
that make sense.
