I have roughly 1,000 GeoMedia "GeoWorkspace" (.gws) files, each a specific map of a single location/area.  We are considering getting away from GeoMedia.  Is there a way to convert .gws to .mxd/.aprx so as to retain the cartographic layout work that has been invested in the GeoMedia .gws?  My searches so far have yielded results mostly concerned with data conversion, not map content/layout.

I need to automate the creation of nearly 100 check-outs .gdbs.  Each check-out will have a site-specific name and be limited to a geographic extent from boundary layers of the same name.  Are there some existing tools that may get us started, or will this need to be a from-scratch effort?  I put together a simple process with arcpy.CreateReplica_management to create a single output, but I'm trying to wrap my head around the rest of our requirements.  Thanks for any help nudging me in the right direction.

Is it possible to use the coordinate system from a data frame in the current map document within an update cursor? I have data in GCS WGS84 and I want to update area/perimeter/length fields across a geodatabase with UTM WGS84 units.  I want to acquire a coordinate system for the cursor from the current map data frame coordinate system, not a reference feature class.  A piece of my current script is below, which would return useless area/length values from GCS coordinates: for fc in fcList:         fc = fc +"\\"         fieldList = arcpy.ListFields(fc, 'lengthSize')#lengthSize field         fieldCount = len(fieldList)         if (fieldCount > 0):             print "perimeterSize field present in: " + fc             arcpy.AddMessage ("perimeterSize field present in: " + fc)             with arcpy.da.UpdateCursor (fc, ['SHAPE@LENGTH', 'lengthSize']) as cursor:                 for row in cursor:                     row[1] = row[0]                     cursor.updateRow(row)                     print "Updating 'lengthSize' field in: " + fc                     arcpy.AddMessage ("Updating 'lengthSize' field in: " + fc)         else:             print "No lengthSize field in: ", fc             arcpy.AddMessage ("No lengthSize field in: " + fc)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Is this possible, or does a "describe" (like that found here: http://pro.arcgis.com/en/pro-app/arcpy/get-started/setting-a-cursor-s-spatial-reference.htm) have to be used?

Is it possible to create multiple, check-out replica geodatabases via script?  We have a SQL Server, GCS WGS84 sde (all feature datasets are in the same GCS WGS84 coordinate system) database containing data from around 100 locations across the country (continental United States).  Each location edits data independently.  The schema is quite large, comprised of some 500+ feature classes across 30+ feature datasets.  Check-out dbs for each location must each be in local, UTM WGS84 coordinate system (we are using the methodology described here: http://support.esri.com/technical-article/000009764 ).  Due to our disparate configuration, along with other network challenges, sde connection speeds are incredibly slow (creating a single check-out takes over 5 hours machine time).  If possible, I'd like to script the check-out replica creation process to automate production of the approximately 100 check-out replicas. Is this possible? Thanks Justin ... View more

For various reasons our organization still uses ArcGIS 10.1.  Our geodatabases have multiple feature datasets, but they all have a common coordinate system.  Individual geodatabases represent specific sites across the country.  I'm using the batch project tool to reproject several gdb that are in UTM WGS84 to the local State Plane NAD83.  It doesn't seem to make a difference whether or not I apply a transformation or not during the reprojection, as the outputs behave the same in ArcMap.  When adding to ArcMap, if I do not use a transformation in the data frame coordinate system, they don't align but will when I apply a transformation.  It does not matter if the data frame is in WGS84 or NAD83.  The transformation I'm using is WGS_1984_(ITRF00)_To_NAD_1983. If I apply a transformation during the reprojection, shouldn't that negate the need to manually apply a transformation in ArcMap?  Thanks Justin ... View more

Wasn't sure how to name this post... I have a geodatabase with multiple feature datasets, each containing multiple feature classes of various polygon, line and point geometry type.  Every polygon fc has a 'areaSize' field that I need to populate with square feet (all of the fds are in State Plane feet). I think I'm getting close here, but still getting an error.  (Eventually I will expand this to perform a similar calculation for length of line fc types as well. The error I receive is attached.  Any help is greatly appreciated.
