I was looking for this.. thank you!

I've successfully registered an on-premise PostgreSQL Database within ArcGIS Server. I've also been able to establish a database connection to an off premise PostgreSQL Database and can read and write data on this database. Now, I'm trying to register the very same (off-premise) PostgreSQL Database on the ArcGIS Server. To make sure that my input is 100% correct, I import the the database connection (.sde) that I previously successfully established. But when registering the database, I get the following error:

I've some historical maps that I want to integrate in a spatiotemporal database. I've found a very good instruction here that explains just that: Creating a mosaic dataset containing raster data from multiple dates—Help | ArcGIS for Desktop I would now like to dynamically change the raster files that are displayed. The "time slider" would be ideal for this, yet this tool is not flexible enough for my purposes. Is there a way I can define conditions dynamically (say, in the "footprint" layer) as to which layers are displayed / drawn in the layout view? Preferably with arcpy, since I have quite a lot of data.

this feature still seems to be unavailable.. any plans to implement it?

Hey Russ Almost exactly one year later, I'm experiancing the same problem. I have a map application with a host feature service that is editable for my AGOL group. I was able to view and edit it with the Collector App, but when by mistake I removed the editing capabilities and later readded them to the hosted feature layer, the map disapeared permenantly from the app. Any ideas for solutions? EDIT: It seems there ws n issue with concerning the rights on the hosted feature layers. Some layers were open to everybody, others were only for a certain group. I've recreted the app and now it works!

Indeed, the problem lies with an error in my shapefile! I drew the grid myself using an arcpy and pyshp and drew each square counterclockwise. Apperently, this only was a problem when I applied the random points tool. Thank you so much for the advice!

Thanks for your answer! Unfortunalty, the result ist the same. 49 Points, as expected, but all on top of each other with weird coordinates (9.85771519532085e-273 /1.02643732661912e-299 rather than somewhere around 600000 / 200000).

Hey Guys, I'm trying to use the tool "Create Random Points (Data Management)" in order to distribute 1 random point per Polygon using arcpy. My script is the following: arcpy.CreateRandomPoints_management(out_path = "C:/Data/", out_name="random.shp", constraining_feature_class="C:/Data/Grid3b.shp", number_of_points_or_field=1) The weird thing is, the output create contains the expected amout of points, but they all have the same coordinates (i.e. are "on top of each other) and are far off from where they should be. I've uploaded my the constraining shapefile here, can someone help me out?

In order to sample a certain area, I produced a 2.1 x 2.1 km grid with 300m rasters.

Thanks for the answer! It's kind of what I expected, I was just confused since the possibility of setting "line fill" was there in the first place..

Hello Everybody, I have a GRID Raster with 8 Bit Integer Cell Values ranging from 1 to 4. I would like to change the symbology using Line Fill and/or Marker Fill accessed via "Symbol Selector" -> "Edit Symbol" -> Type: Line Fill Symbol". This doenst seem to work: The the values are simply filled with the color I chose the lines or points to be in. Is "Line Fill" simply not possible with GRID Raster data or am I doing something wrong? Thanks in advance!

Hi Guys, We're collecting data on mammal sightings from the general public. I've recieved the feedback, that several users are missing a "submit" button once they've entered the data. Is there a way to incorporate this? Here's a Link to the application: https://zhaw.maps.arcgis.com/apps/OnePane/basicviewer/index.html?appid=df80252abfbf41f6b68a40a04f36f8ec Thanks in advance! Nils

Hello everybody, I sure hope this is the right subforum. If not, please redirect! I've been looking for hours for a simple tool, I can hardly believe why I havent found it yet! It's basicly what the "Near" tool does, but instead of returning the distance (or angle) of the nearest Feature, I want the tool to create a column with a value of my choosing. For example: I have a couple of layer of points and one of polygons. The polygon layer has a column with the attribute "name". I want the near feature (in this case the polygon) to add the value "name" to the point feature. Is that in any way possible? Thanks in advance, Ratnanil
