sorry for misprint in Feature naming; here?s corrected one. /Janne _____ From: Janne Porkka [mailto:janne.porkka@xxxxxx] Sent: 17. lokakuuta 2005 16:12 To: 'landxml@xxxxxxxxxxxxx' Subject: ReferenceStationing to rail alignment Dear all, We are preparing procedure for transferring ?alternative/reference stationing? information in railway alignments. By this we mean the actual rail kilometer length information (can be e.g. 999.1919 meters) that is relevant especially in existing railways where old rail alignment serves as the reference. I hope that Features below under Alignments helps in understanding. It provides internal staStart and staEnd and actual ?on rail length? values for generating lists for each rail kilometer. This information is also modifiable to metric/imperial units. <Alignments desc="" name=" " state=""> <Alignment name="yyyy" length="11381.4613" staStart="112000.0000">?. </Alignment> <Feature code="IM_referenceStationings"> <Property label="desc" value="km posts in railway xxxx"/> <Property label="alignmentNameRef" value="yyyy"/> <Feature code="IM_referenceStationing"> <Property label="name" value="km1"/> <Property label="staStart" value="112000.0000"/> <Property label="staEnd" value="113139.8080"/> <Property label="length" value="1139.8080"/> </Feature> <Feature code="IM_referenceStationing"> <Property label="name" value="km2"/> <Property label="staStart" value="113139.8080"/> <Property label="staEnd" value="114138.9999"/> <Property label="length" value="999.1919"/> </Feature> ... </Feature> </Alignments> I have an understanding that this information belongs to design practices in European/Scandinavian countries. I?m looking forward to seeing solutions, possibly already implemented ones. In case this piece of information is really needed there is a possibility to attach it into new <railway>.<cant> or directly under Alignments to support other than railway cases.
