With the recent release of ArcGIS Online, I was excited to see you could place multiple layers within the base map. As such, I was hoping to create hybrid web maps with feature labels (map service) overlaid on imagery (image service). This seems to work fine if I'm using Chrome as my web browser (which is my default), but the feature labels map service does not show when using Internet Explorer (I'm using IE 11). The web map I have published is here, and shared to everyone. Any ideas why it seems to work in Chrome, but not IE? ... is it because of the 2 different types of services? ... something else?

I'm fairly new to mosaic datasets and managing imagery, and I was wondering how all the other experts out there manage their imagery using mosaic datasets? In particular, I was wondering if you have several mosaic datasets within 1 gdb, or if you create a separate file gdb for each mosaic dataset? Pros and cons of each method? Any tips / recommended tools for optimizing performance?

Cameron McCormick, Take a look at the screenshot below. This is what I have found works in ArcGIS Pro. I moved all the bottom line markers into a new group, placed that at the bottom, and organized the symbols in the drawing order. I then organized the top line markers (original groups) in the drawing order I desired. This resulted in joined/merged lines. There could be a better solution within ArcGIS Pro, but after looking at layers from a mxd I imported, this seemed to be what was done with those layers that were drawn already joined/merged from the imported mxd. Hope this helps!

I'd rather not produce another layer I have to manage. Is this not possible with ArcGIS Pro...? I would have thought this would be something rather simple...

How do you join/merge line symbols in ArcGIS Pro? For example, in the screenshot below my roads are symbolized individually and I'd like them to join/merge to show contiguous road segments. I found Symbol layer drawing, but that doesn't seem to do any joining/merging, just sets the drawing order, unless I'm missing something...

Aravind Sivasailam, That would be awesome if updating the vector tile package and then publishing it would create the same URL. I'm sure that would save a lot of people a lot of time. Let me know what you find out, and thanks for testing this out!

Aravind Sivasailam, Thanks for the reply! One other quick question I had that I forgot to mention above... Are vector tiles similar to hosted tile layers on ArcGIS Online where a tile package is unpacked and a tile layer is created from that package, which produces a unique URL to the service hosted on AGOL? If so, suppose I wanted to update a vector tile layer and I go through the same process of uploading the tile package and unpacking it only to have a new URL created. Would I have to update any web maps / apps in order to use the newly updated vector tile layer? This issue is the main reason we, as an organization, haven't used hosted tile layers, in that there doesn't seem to be a way to update an existing layer, only create a new one and thus have to update any web map using the previous tile layer. There doesn't seem to be a way to overwrite an existing layer in order to keep a contiguous URL. Do you happen to know if the workflow for vector tile layers is the same as hosted tile layers in this regard?...upload package, unpack package, new URL is generated.

I've heard about vector tiles quite a bit recently but am not sure I understand how they work, how to create them, or how to host them...so I was hoping someone could clue me in to the following questions I have below... 1) How do vector tiles differ from traditional tile caches? 2) How do you create / author vector tiles? 3) How do you update vector tiles? 4) Can vector tiles be hosted on a local ArcGIS Server? 5) Do vector tiles create a map service similar to a cached map service? 6) Are there obvious advantages / disadvantages to vector tiles over a traditional map cache?

Jake Skinner, The difference you have in your sequence is you sync changes after doing a reconcile and post. Does this flush out the sync versions in sde? To me, that seems to be the issue, or hang-up on my end. I have sync receive and sync send versions in the sde_versions table with the 'edit' version as the parent. Therefore, I'm unable to delete the 'edit' version because there are child versions.

Jake Skinner, Why is it after I sync changes between the 2 gdbs, and then run a reconcile and post to the DEFAULT version, the edits are not being pushed to the DEFAULT version? The edits do show in the edit version. Also, a compress is not pushing edits to the base table. Does it matter in a 2-way replication which gdb is gdb1 and which is gdb2?...which is a sender and which is a receiver? I'm trying to automate the process using python. Below are the sequence of steps I'm taking: 1) Block connections to my sde gdb 2) Compare schemas 3) Sync changes (between sde gdb and geodata service) 4) Reconcile and post edits to default version 5) Analyze datasets 6) Compress gdb 7) Rebuild indexes 😎 Analyze datasets 9) Accept connections to sde gdb One other quick question...does the version automatically get pulled across when creating a replica?...i.e. if your connection file is connected to a version, will that version get created in the gdb receiving the replica?

Jake Skinner, I'm re-visiting this thread in order to find out what you think is the best workflow for 2-way replication in terms of versioning. What I mean by this is, in your opinion, if we were to setup a 2-way replication process using a geodata service as one of the gdbs, would you recommend syncing the replicas to a common version, or different versions? Let me try to provide an example: Scenario 1 GdbA and GdbB both have an 'Editing' version. The replicas are based on the Editing versions, so when syncing is done each replica is syncing to the Editing version. Scenario 2 GdbA and GdbB both have a 'CityEdit' and 'CountyEdit' version. The County would edit within the 'CountyEdit' version and the City would edit within the 'CityEdit' version. The County would have a geodata service reading the 'CityEdit' version and the City would have a geodata service reading the 'CountyEdit' version. This way when edits are synced the would be put within separate versions and then reconciled-and-posted. I'm wondering if you think it's worth having 2 separate editing versions?...or if it's just as well to have 1 common version that edits would get synced between before being reconciled and posted to the default version? Perhaps there's a scenario I'm not thinking of that would be a better workflow, and if so, I'd appreciate any insight.

Jacob Boyle When I right-click on the child gdb, go to Distributed Geodatabase, and Import Schema Changes...I am presented with a wizard that gives the option to confirm the deletion of 'Field2'. It is unchecked by default, which is what I'm guessing is being done through scripting...the field not being confirmed for deletion. I only get this wizard when doing the workflow I describe. If I use python or even the tools from the toolbox, I'm not presented with this. This seems very annoying when trying to automate a process that would be run during off hours when users are not connected to a gdb and have locks established. I'm wondering why adding a field doesn't get the same result; it is added through scripting, while deleting a field is not removed through scripting.

Nope...field (Field2) still exists. Child gdb is on left, editing gdb is on right.

Jacob Boyle, I'm using the .xml file produced after comparing the schemas. I just added a field in my editing gdb and it is added to the child gdb after running my script. Below is a skeleton of the python code I'm using... import arcpy
import datetime
import os
def compare_replica_schemas(gdb_1, gdb_2, replica_name, output_file_folder):
# gdb 1 is editing gdb
# gdb 2 is child gdb
run_time = datetime.datetime.now().strftime('%Y-%m-%d_%H-%M-%S') # used for creating unique file name
schema_file_parent = os.path.join(output_file_folder, run_time + '_schemaParent.xml')
schema_file_compare = os.path.join(output_file_folder, run_time + '_schemaCompare.xml')
# export schema from editing gdb
arcpy.ExportReplicaSchema_management(gdb_1, schema_file_parent, replica_name)
# compare replica schemas
arcpy.CompareReplicaSchema_management(gdb_2, schema_file_parent, schema_file_compare)
# import replica schema to child gdb
arcpy.ImportReplicaSchema_management(gdb_2, schema_file_compare)
