Hello Cole, We decided to deploy ArcGIS Online user accounts instead of the other options at this time. The ArcGIS Online users can create web maps and drag/drop or add csv address files to the map. You can also set this to use your own geocoder so it does not use any credits. This also provide the ability for them save their maps, share, and edit the points. Overall there are a lot of nice features (as I am sure you are aware). However, the BIG caveat is it bottle-necked by the number of named users of your organization. We have nominated a few individuals from each department to have this access, while others will simply consume the maps created. Back to the original topic: I did find a couple solutions. One solution which is a simple html web page you can host which supports drag / drop of csv using javascript. It sends your csv to the server and plots markers on the map using Leaflet.js I am a big fan of Leaflet and would personally like to deploy this option, however, due to requiring some knowledge of HTML, the ArcGIS Online option is a safer bet for our initial roll-out. Leaflet is extendable to add other capabilities but excels at providing a simple map for embedding in web sites. I'll look at work tomorrow to find the link and example. I did attempt the geoprocessing widget / service but there were issues with it accepting a file upload in the Web App Builder environment - there may still be an solution here but I invested a bit of time without success. The good news is esri knows about this request and it may be in the works.They just added a geolookup widget which takes a CSV input in the Web App Builder. This requires a lat long coordinate and does not run through your own geocoder - so hopefully sometime soon they will post a new or adjusted widget. Thanks for your interest. Let us know if you find something else. ... View more

Right, I saw that it uses the findAddressCandidates method while looping over each candidate.  I wonder why it Mr. Crickard chose this instead of the method you described. The response seems fairly snappy for the small sample set I have. I intended on adding a results passed counter and other plugins like heatmap display. How do you handle the file upload process to get your initial candidate list? (This is before it is converted to JSON or sent via the url request as shown above). ... View more

Thank you Paul! This is incredibly helpful.  I appreciate you posting your code and lightweight use of Leaflet. ... View more

Hello Mark, I re-extracted my DEM trying to avoid NoData values and resampled it to a coarser resolution (10 ft vs 4ft). I then ran Fill Sinks with my deranged polygon feature class which worked this time.   You clued me in that the source DEM was probably the issue, though I am not sure if it was the raster type (signed, unsigned, integer vs real), size, or it simply my raster was corrupt. The previous failure: 1) The failed Con() function had a message: Failed to execute. Parameters are not valid. ERROR 000865: Input true raster or constant value: C:\Users\lmsanders\AppData\Local\Temp\arc8352\AH20150527141646\fillGeo does not exist. Failed to execute (Con). Description The specified input to the argument does not exist. Solution Make sure the input exists at the identified location. 2) Step that would have created the fillGeo Had the following errors: ERROR 010213: Error in reading raster c:\hydro\raster\leveldem. Description There was an error encountered when trying to read the specified grid. Problems accessing a grid are most commonly the result of missing required component files in the grid's folder. Consult the documentation to see the required files for the ESRI Grid format. If all of the required components are present, it is also possible that the files that contain the binary raster data are internally corrupted. Solution Determine whether the grid is valid first by trying to display it. If it does not show properly, check to see that all the required component files are present in the grid's folder.If there is no sta.adf file in the grid directory, try creating one with the Calculate Statistics tool. If its data files seem to have been corrupted, you may need to re-create the grid. Hopefully, you have a backup copy that can be used, or you can run the process that created it again. ERROR 010067: Error in executing grid expression. Description There was a problem executing the map algebra expression. Solution Check the syntax of the function and ensure that you are correctly specifying all the required and any optional parameters. Be sure to check that the data type is correct. For example, specifying a character string in the command when a numerical value is expected may cause this error. I will try a bit of experimenting to see if I can track down exactly what was the issue. ... View more

Thank you for your time and thoughts on this issue.  Thanks for clarification on the Con() function.  My raster DEM is an signed integer Esri GRID format with NoData value set to 32767 under the raster properties.  There are areas with NoData as classified below in red.  I thought, according to the help, that integer GRIDs were the desired format.  I will try to extract the area to minimize NoData values.  I think the fillGeo does not exist because the previous step that would create it fails.  The current DEM is about 660 sq miles at 4 ft pixel sizes.  Perhaps this is too large and I should tile the processing or reduce the resolution. ...

Update I ran the Fill Sinks tool without any deranged real sinks (leaving the parameter blank) so that it would fill all sinks in the DEM.  The tool succeeded without a hiccup.  This leads me to believe it is something to do with the polygon for my sinks or the extra processes involved when enforcing real sinks?  These are stored in a file geodatabase but not in a feature dataset. ...

Hello Mark, Thank you for your reply.  I am having the usual frustrations with Arc Hydro and have been following the Problem Solvers thread closely.  I have been reading a number of your other responses in this community.  I have forgone building walls altogether and am now using a merged DEM that exceeds my area of interest.  I am avoiding the build walls errors at least for now.  I was able to run Level DEM using a lake polygon feature class. I now wish to run Fill Sinks.   Fill Sinks fails on the final step "Fill . . ." due to the following does not exist error: ... Failed to execute. Parameters are not valid. ERROR 000865: Input true raster or constant value: C:\Users\lmsanders\AppData\Local\Temp\arc8352\AH20150527134547\fillGeo does not exist. Failed to execute (Con).

Hello Zachary, Here is the link to my similar post, without a lot of strong leads.  Below is what I've heard so far from Esri Esri Customer Care Rep: I was able to look into this further and it was more efficient that I email you back with some further information on how to accomplish your goal. While the out of the box applications in the Web App Builder won't support batch geocoding your geocode service, you have a couple of options. You can create your own widget that will allow your users to upload the csv file to have them batch geocoded or as you mentioned, create a geoprocessing service that will allow that to happen. I think that the following documentation may help you in what you are wanting to accomplish. http://gis.stackexchange.com/questions/58095/geocoding-multiple-addresses-using-arcgis-js-api https://developers.arcgis.com/javascript/jsapi/locator.html I wanted to include some helpful documentation about creating geoprocessing services and publishing them.

Hello Kevin, How far are you able to zoom in on your map?  In the web map you can see your scale by going to "Set Visibility Range" for a layer under "Map scale is ..." When you add a layer, check the box "Use as basemap."  This basemap will set the scale levels for the web map.  If it is a cached service, it will use the tile zoom levels.  If it is dynamic, the zoom will go down to 1:0 in my testing. ...

Hello Kevin, The ArcGIS Online zoom levels are determined by the basemap used in your webmap.  Is the map not zooming in further than the standard zoom  at 1:1,128?  Try replacing the basemap with a cached layer with closer zoom levels. ... View more

Thank you Brad. This is something I have to set down for a couple weeks, but look forward to looking at the reference you provided.  Here are the options I've come to so far. I had hoped to use the Geoprocessing widget to run a GP task on a user supplied file.  So far I have found that the GP Widget in the Web App Builder cannot take a user file upload.  However, it can process a file if the input is a string filepath - so long as this filepath points to a document already located on the server.  i.e. "C:\arcgis\input\example.csv" points to the server C: drive rather than a user drive.  This does not solve the problem. My next option would be to make a custom widget.  This requires taking the Web App Builder off AGOL to our local servers so this is not a great solution, requiring additional maintenance. Third we could use AGOL web maps to batch geocode with drag/drop tables after setting the default geocode service to our own service in the organizational settings.  This would work well except that it requires named users for our AGOL organization.  A similar option may be to use Google's open apps such as My Maps & Fusion tables thereby bypassing the user restrictions.  This would not use our own geocode service. The final option is to build a focused app using the JS API with the sole purpose of geocoding and displaying points. Here are a few helpful resources: Kevin Hibma‌ authored the helpful video Creating and Working with Geoprocessing Services | Esri Video Includes example demo with upload file. Additionally this thread looks promising Upload File to ArcGIS Server Customizing and Extending Web AppBuilder for ArcGIS | Esri Video      My magic genie wish would be to have the Esri Web App Builder official release include a new widget specifically for the batch geocode task as batch geocoding is a common request across the GIS field. ...
