ArcGIS File Geodatabase – Programmatically Determining Size of Feature Class

arcgis-10.0arcobjectsesri-geodatabasefile-geodatabase

My answer to the question How to get size of file geodatabase feature class on disk? shows how one can enable a column in ArcCatalog showing the file size of FGDB feature classes in the contents view.

Does anyone know how ArcCatalog is able to calculate this, and is there a method or property exposed in ArcObjects or another API to determine this programmatically?

I had a look through the esriGeodatabase ArcObjects namespace and did not find anything relevant, nor in the file geodatabase API, but I may have missed something.

AFAIK, the columns (like size) that appear in the right hand pane in ArcCatalog correspond to properties in IGxObjectProperties for the item selected in the treeview control in the left hand pane.

[GIS] How to import DGN geometry into a file geodatabase

Your "Group Layers" in the file geodatabase will be Feature Datasets because the former exist only within maps and layer files.

If you have the same coordinate system stored for both the Feature Datasets you designed and the one that came in from your DGN file then as long as their schema match you should be able to copy/paste Feature Classes from one Feature Dataset onto another.

To be "slicker" in your conversion you may want to look at the Data Interoperability extension which has FME under its hood.

[GIS] Copying feature classes from Personal Geodatabase to File Geodatabase using ArcPy

The following script converts all of the feature datasets and feature classes of a personal geodatabase to a new file geodatabase.

import arcpy, os

# Set the in and out workspaces
inws = r'C:\temp'
outws = r'C:\temp\outws'

# List the Access Databases
arcpy.env.workspace = inws
mdbs = arcpy.ListWorkspaces(workspace_type = "Access")

count = 1
for m in mdbs:
    # Define output FGDB name
    fgdb_name = os.path.basename(m).split(".")[0] + ".gdb"

    # Create a new FGDB
    arcpy.CreateFileGDB_management(outws, fgdb_name)

    # Copy any FCs that are directly in personal geodatabase
    arcpy.env.workspace = os.path.join(inws, m)
    fcs = arcpy.ListFeatureClasses()
    for fc in fcs:
        arcpy.CopyFeatures_management(fc, os.path.join(outws, fgdb_name, fc))

    # Report on processing status
    print "%s of %s personal databases converted to FGDB" % (count, len(mdbs))
    count += 1

    # List the feature dataset
    arcpy.env.workspace = os.path.join(inws, m)
    fds = arcpy.ListDatasets()
    for f in fds:
        # Determine FDS spatial reference
        desc = arcpy.Describe(f)
        sr = desc.spatialReference

        # Copy FDS to FGDB
        arcpy.CreateFeatureDataset_management(os.path.join(outws, fgdb_name), f, spatial_reference = sr)

        # Copy the FCs to new FDS
        arcpy.env.workspace = os.path.join(inws, m, f)
        fcs = arcpy.ListFeatureClasses()
        for fc in fcs:
            arcpy.CopyFeatures_management(fc, os.path.join(outws, fgdb_name, f, fc))
