Using Transportion data model, error

DougArnold — Mon, 28 Jun 2010 14:20:40 GMT

I am trying to use the Transportation data model for the first time, specifically to so a traffic sign inventory. I am getting this error "the add relation command could not be completed. unable to obtain primary key value for origin object" when trying to add a new intersection point. I actually can;t figure out how to add a stop sign (for example) to an intersection using this data model??

Doug,

Are you using the new transportation data model available at http://resources.arcgis.com/content/transportation-data-model?

This is a highly relational data model based on linear referencing. The trans model represents the logical model described in Designing Geodatabases for Transportation by J. Allison Butler. This data model contains very few feature classes and is a highly relational model for data maintenance. In other words, it's not just a simple centerline and point feature class schema. It assumes your asset data is stored in tabular form with a route reference and a measure value.

The trans model is not plug-and-play. It requires thoughtful consideration of your data needs and your maintenance requirements prior to implementation. In order to get full value from this model you will also need to create maintenance applications through ArcObjects, stored procedures in your RDBMS, or implement ArcGIS Production Mapping including workflow management and data review.
