Essentially I want an end user (who is using a Web App Builder application, or any of the suite of other online apps, like collector, survey123 etc.) to be able to submit a pre determined shapefile or feature into ArcGIS online. This shape would then be added to an existing feature layer that is stored on AGO. The shape could then be used for analysis within a web app builder application. Unfortunately the "Add Data" widget only adds data to the application, and doesn't allow many of the widgets to access the data to perform analysis, so it doesn't exactly help. Essentially I need the same functionality of the "Add Data" widget, but the data will actually be added to a feature layer permanently, which can then be used to select features with the batch editor. ...

Hello, I currently have an arc online tool that allows users to enter data for polygons based on their overlap with a larger territory layer. Unfortunately due to the nature of web app builder, the user is also able to enter values into a corresponding territory field (in the polygon layer), even if there is no overlap. Because of this issue, I am writing a tool that checks for these errors. Unfortunately I keep running into an issue.  The two datasets look like this:  Polygon layer: OID Territory1 Territory2 Territory3 Territory4 Territory5 etc..... 1             2       Response     3             4   Response Response         Territory layer: OID FIELD_NAME 1 Territory2 2 Territory3 3 Territory4 4 Territory5 etc... etc...   Essentially I want to select an individual territory (from the FIELD_NAME field), intersect it with the polygon layer, reverse the selection (so all polygons that are not within the territory are selected) and then test to see if that specific territory field within the polygon layer has any values in it. If it does, then there is an error and I want that to be displayed in an error field with the number of errors.  Currently, my code seems to just be adding 1, regardless of any data that is incorrect/correct in the dataset. Keep in mind I have a break statement in my code, so after one iteration it stops (for testing).    Any Ideas?   Here is my code (ive changed the dataset names etc):          def check_errors(): env.workspace = gdb_name print ('--------------------------------------') print("check_errors()") arcpy.management.AddField('polygon_areas', "OVERLAP_ERROR", "LONG") #create layers polygon_layer = arcpy.MakeFeatureLayer_management('polygon_areas', 'polygon_layer') territory_layer = arcpy.MakeFeatureLayer_management('territory', 'territory_layer') print("layers created!") overlap_error_count = 0 overlap_error_field = ["OVERLAP_ERROR"] #clear error field: update_cur = arcpy.da.UpdateCursor(polygon_layer, overlap_error_field) for row in update_cur: row[0] = 0 update_cur.updateRow(row) print (' Cleared error field') #------------------------------------------------------------------------------------------------------------------------------- territory_fields = [ 'Territory1','Territory1','Territory1','Territory1','Territory1','Territory1','Territory1','Territory1','Territory1', 'Territory1' ] #cycle through each field that corresponds to territory name, check for errors for name in territory_fields: print("Currently Processing: " + name) print(datetime.datetime.now()) #select a territory, intersect with the polygons, and select all polygons that fall outside of the territory #do any rows have values within the territories field? Should be empty arcpy.SelectLayerByAttribute_management('territory_layer', 'NEW_SELECTION', "FIELD_NAME = '" + name + "'") arcpy.SelectLayerByLocation_management('polygon_layer', 'INTERSECT', 'territory_layer', "", "", "INVERT") #look at the territory field, add a 1 to the error field if there exists data within the territory field update_cur = arcpy.da.UpdateCursor("polygon_layer", [name] + overlap_error_field) for row in update_cur: if row[0] != "" or None or " ": row[1] += 1 update_cur.updateRow(row) print ('overlap errors calculated') arcpy.CopyFeatures_management('polygon_layer', 'Polygon_features')             Thanks in advance! Im pulling my hair out with this one.  ... View more

Hello,   I'm currently using the batch editor widget to update the fields in a set of feature views (3 separate layers). Each view points to the same feature layer. The issue arises when I try to use the batch editor to update the fields if the 3 feature views. Each field has a coded value domain (6 selections) with Null values allowed set to yes. I want a way for editors to be able to set the field to "no value" if they feel they need to edit a response / delete an entry. Unfortunately this option is not available for all fields, only the first in the list. Currently this field has no values entered into it. The No Value option shows. This will show even if there are values in the field.    The rest of the fields, whether populated or not, do not display the "No Value" option - only the top field in the list.   Any Idea why the No Value would only appear on the first field? I would rather not have to put a "Blank" or "Null" value in the actual domain list as this would complicate things, but this seems to be the only option if this is a bug.  (also sorry for all the redacted text, I hope its still clear enough)   Thank you!                   ...

Hello,  I have a bit of an odd question. I currently have a point dataset that has been randomly generated over a land base. I want to create a set of polygons at said points, corresponding to an area field, where each polygon will be 1, 2, 3 or 4 hectares in size (this is done in a random fashion). I am able to achieve this by either using the buffer tool or by using the table to ellipse tool (where I need the major and minor axis), and simply adding a field within my point features which determines which size the polygon will be, and then creating an if statement that builds the size of the buffer/table to ellipse based on this... My question is, I am looking to find a way to generate polygons at these points that are not perfectly circular or an ellipse. I have a set of 4 pre-drawn polygon shapes (oblong/uneven shapes that are not exactly buffers/ellipse) which I would like to map at the same location of these points. Again, these polygons would be randomly set to each point, with a random designation of 1,2,3, or 4 hectares.  I have 100s-1000s of points, so I would like to automate this, but I have not found anything that would be appropriate for this problem (other than a simple buffer or table to ellipse). I figure it would be some sort of copy operation, where a polygon is copied from a template, and then built at the point, but I'm not sure how to accomplish this.  Again, a fairly odd problem, but I just want to cover my bases by asking the net.  Thanks in advance! ...
