Looking for a solution which database to use so 2D DGN data can be exported to GIS spatial database but with keeping curves and arc elements so are easy editable(not stroked) after query from database.
This is needed for land surveying workflow with multiple surveyors working in one large area but different places. As multiple users cannot open the same design file at the same time they are struggling with updating data in same large DGN wich contain all Project area it would be better that features are stored in a spatial database, each user will work in their own individual design files but at the end of the day promote the changes to database.
Does Oracle Spatial or ESRI GDB support this?
Connection / Database Type
Circular Arcs
Elliptical Arcs
BSplines
PostGIS
Yes (10 or higher)
No
SqlServer
Yes (2012 or higher)
ArcGIS
Yes
Yes, as Bezier
Oracle
Approximated with BSpline
Yes (NURBS)
ESRI File Geodatabase supports both circular and elliptical arcs. It also has support for import (but not export/post) of Bezier curves.
That all is nice on paper now we need such table but for Bentley Opencities Map what does it support?
This is how the Map software stores those geometry-types. Where there is a No in the table, stroking is likely to occur during the Post operation.
