I am using ArcHydro for Pro (2.0.15) and ArcHydro for ArcGIS (10.6.0.40) - but I found the same issue on other recent versions. I have a very large area with 58,000+ catchments and drainage line segments. About 20-30 of these catchments have two drainage lines within the same catchment (same gridid identified) - essentially where a side stream flows into the catchment. Running the Adjoint Catchment process works, but fails to create adjoint catchments for some (but not all) of those catchments with more than one drainage line. The attached image shows an example with a catchment containing two drainage lines, and then a side line in a different catchment that enters from the bottom. The drainage lines are selected. The other picture shows the adjoint catchment in green and you can see how it left our the catchment with the two lines - and the upstream catchment with the one line.  Here is what I know and the hack I used to solve it. I am looking to understand the cause and then to know the correct solution. The drainage lines all show the correct from, to, nextdownID - and the gridid for both lines is the same catchment.  This problem DOES NOT occur with all of the catchments that have more than one drainage line. About 20-30 catchments have two lines, but only 12 of the catchments result in a missing adjoint catchment. I cannot see anything different between the ones with and without the problem. I can solve it using two different techniques: (1) for the example when the second line is a terminal upstream segment I just deleted that upstream segment; (2) for catchments where the two lines are part of a river I split the catchment so that each line has a separate catchment.  Both solutions work to produce a complete adjoint catchment.  Is this a bug? Is there an ArcHydro tool designed to fix/avoid the problem of multiple drainage lines within each catchment? Should a catchment be allowed to have two drainage lines? ... View more

Hello, I have a contour layer on OpenData being pulled in from a map service running on one of our servers via ArcGIS for Server: http://data-waterinstitute.opendata.arcgis.com/datasets/lake-bathymetry  http://gis.waterinstitute.usf.edu/arcgis/rest/services/Maps/Bathymetry/MapServer/2  Whenever I try to download it attempts to gather the data for a moment, but eventually fails. I've set my download cache to manual and updated the index through the admin tools, but that doesn't seem to have fixed anything. I've noticed a few people have had this issue before, and occasionally somebody as ESRI was able to remedy the problem. I'm hoping this will be the case here. If not, maybe someone can offer some suggestions on how to fix it on my end. Thanks in advance, Rich ... View more

We are just about to implement our new AGOL based mapping application and I keep running into this issue. We have a dedicated server running ArcGIS Server 10.3. The MXD document we are publishing resides there and this service gets loaded into AGOL as a map image layer. This map image layer is included in our web map. I spent a LOT of time configuring the attributes for each of the layers in this web map. After I was done we decided to add some more layers to the original MXD. We updated the map service on our server by overwriting it. The map image layer on AGOL shows all the new layers we added via the REST endpoint. When I reopen the web map it also shows all the new layers that were added (yea!), but when I go to click on a feature, the resulting popup window shows the attributes for the old layer that was originally in that spot within the Table of Content order (boo!). The only way I have found to fix this is to delete the entire image layer from my map, reimport it, and reconfigure all the attributes again (immense boo!). So, it just seems that the AGOL web map isn't capable of reordering the layerIDs based on the new stuff that has gotten added in. Does anybody know a way to make it do this? I can't imagine that ESRI wouldn't allow for the addition of new data without having to reconfigure every single data layer in your web map. Thanks in advance, Rich ... View more

Hi All, I've been stuck on ArcGIS 10.0 for a while, so our recent jump to 10.3 has been a bit of a learning curve. One problem I can not overcome is having changes I've made to my map document appear on my map service after I've saved my changes in the mxd file and restarted the service. For example, I create the service with small, brown points and publish it. Everything is fine. If I then try and change the symbology to medium-sized yellow points, save the document and restart the service, the points remain small and brown in my published service. Stopping and then starting the service has no effect either. I've done this in both ArcCatalog and the ArcGIS Server Manager. If I choose to share the document again via ArcMap and then overwrite the existing service, the changes finally appear. So I could do this every time I make a change, but it's not ideal. I just want to know for my own sanity if restarting the service should make these changes appear. This is how it was in ArcGIS Server 10.0, and from everything I've read about 10.3, this functionality should still be the same. Just wondering what I'm doing wrong..... Thanks, Rich ... View more

Hello, I've began using the Create and Enable Enterprise Geodatabase tools to manage my GIS data in SQL Server as opposed to directly installing SDE. I've been successful in creating and importing new datasets, unless I include an attribute field of type "double". When I do this and try to calculate a value in ArcMap the feature disappears and the attribute table will no longer display, giving me the following error instead:   Could not load data from data source.......Underlying DBMS error [[Microsoft][SQL Server Native Client 10.0]Numeric value out of range]   The layer pretty much become unusable in ArcMap or ArcCatalog at this point.   The precision is 38 and the scale is 8 by default. Even adjusting these values in Management Studio doesn't seem to fix anything. I'm running ArcGIS Desktop 10.2.2 and SQL Server 2008R2.   Does anybody have any ideas or suggestions as to why this is happening and how to correct it?   Thanks in advance, Rich ... View more

We're currently trying to recreate functionality we have in our ArcIMS based mapping application within the ArcGIS Server Flex Viewer. One of the options we currently allow our visitors is to toggle on and off map themes, or predefined groupings of similar layers (i.e. a Recreation theme that will turn on the parks layer, boat ramp layer and trails layer). In ArcIMS we accomplished this through code on the back-end: theme names were passed as a query string in the URL, layers to be turned on and off for each theme were stored in tables within our RDBMS. We're just getting our feet wet with the Flex Viewer and really are not sure where to begin to replicate this feature. We sorted through the standard widgets, but didn't come across anything that sounded like it would work. Does anyone have any suggestions or ideas that can get us going with this?
