<div class=Section1>
<p class=MsoNormal><span lang=EN-US>Hi Frank and list,<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I have several questions which are not
relevant to GDAL/OGR itself, but S-57 format.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Wish any hint, thanks!<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>NO.1<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I’d like to know whether PRIM is as
same as NAME_RCNM? If not, what’s the difference between the two?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>NO.2<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I got some info via ogrinfo from a s-57
file(*.000). In a caution area object(CTNARE),some fields are as follows:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>PRIM=3---------------------------------------------------which
means the object’s geometry is a face, right?<o:p></o:p></span></p>
<p class=MsoNormal style='margin-left:189.0pt;text-indent:-189.0pt'><span
lang=EN-US>NAME_RCNM=130-----------------------------------which means the vector
record’s type is edge, I guess. But the next three fields should exist
with a face vector record(5.1.3.3 chapter in S-57 Editon3.1 seems give this
hint, but I’m not sure it’s true.)<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>ORNT=2:2,2<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>USAG=2:1,1<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>MASK=2:255,255<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>And another two questions:<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>NO.1<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>The field value in spatial records such as “NAME_RCID=2:25,413”
has a prefix “2:”, does it mean the field belong to spatial record
not feature record?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>NO.2<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>And why one is 25,and another is 413?Does
it mean 25 is the ID in spatial record and 413 is the ID in the whole record?<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Thanks a lot!<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Best regards,<o:p></o:p></span></p>
