Geodatabases

Dxf - linework

Shape - Feature type

GDB - database file for GIS

  1. Customer client templates not supported with GDB downloads - Client templates in dxf = template schema in GDB

  2. Only available for 2d bundle and A-La-Carte 2d layers

  3. Blocks will always be converted to points in the GDB - layers that use blocks including MH, CB, Poles, Hydrants, will just be described with one point in GDB at centroid of each block

  4. The supported attributes attached to each feature are shown below. Note all attributes are truncated to a precision of 1 decimal place

    • Lines: (Length)

    • Polygons: (Area, perimeter, outer perimeter)

    • More to come

  5. CRS inside tif is required to generate a GDB

  6. Tif CRS must be in an imperial / metric unit. Arc degrees are not supported. This means CRS's like WGS and WGS84 will cause issues

  7. GDB format does not support arcs so the arcs in our dxf linework will be replaced by very short polylines

  8. Polygons might be generated for some pavemark layers rather than polylines.

  9. The current shapefile download from the app doesn't incorporate nested polygons the same way the GDB generation does. As such, I would recommended to promote GDB's to be used instead of shapefiles when possible as it will likely be a better and more accurate deliverable in terms of handling cutouts.
