Bruce,<br><br>OGR doesn't support all the Shape Types. Curved line segments show up as straight line segments. Could this be the case?<br><br><div class="gmail_quote">On Wed, Apr 28, 2010 at 6:37 AM, Clay, Bruce <span dir="ltr"><<a href="mailto:bclay@ball.com">bclay@ball.com</a>></span> wrote:<br>

<p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I created a shapefile in ArcMap with 5 objects. The
first two are really a collection of many line strings that I copied from a
Census Tigerline file and the other three I created using the ArcMap editor arc
tool. The attached file shows what the shapes look like.</span></font></p>

<p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I can read the two smaller objects using OGR without any
problem. They have reasonable point counts and the X/Y data from the ones
I looked at in the debugger look valid.</span></font></p>

<p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I can not get to the point data in the larger three
shapes. The geometry type shows up as linestrings but the point counts
are way to low (i.e 28, 10 and 3).</span></font></p>

<p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I tried to cast them into OGRCurve, OGRMultiLineString,
GeometryCollection and a few more I think but none of them worked.</span></font></p>

<p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Is there some special way to read data like this?</span></font></p>
