Hi Felicity - thanks for posting. I'm afraid there's no simple way to find the info you're after currently. I think it would be a matter of performing a query on the underlying layers in the map which are valid snap sources, applying a similar tolerance to that which we use internally, and using similar criteria to that which we do internally if there are multiple snap candidates to decide the best snap location. If snapping to utility networks with rules, there'd be extra rules to consider. Effectively this would be recreating the snap in your own code and I'm not suggesting it's a great way to go, because it would be pretty complex and possibly out of sync with the internal events - however if you have an urgent need for this then please send me a direct message and we could discuss this in more detail to see if it would be feasible for your case. If it's a longer-term aspiration, it's certainly an enhancement that we can consider adding more info to the snap event. We'd originally considered what information we should best put in the event when we added it, and went with the minimal approach initially. Other information we could consider exposing would be the details of the feature or features snapped to, or other candidates considered. However it sounds like just the snapped-to Point information would suit what you've described above. If you could again direct message me with any details of your scenario I'd really appreciate that (for example your user story, or use case, who your users are), as I can take this in to account when we're discussing this potential enhancement.

Hi @YasunariTosa1 , I think this could be down to expecations of the input & output spatial reference of a transformation, and the doc not being good enough here. Transformations deal with a change in datum, and that's part of the underlying geographic coordinate system. If your input or output spatial references are projected (which they both are in your case above - IsProjected==true), then instead of checking the WKID directly, check the BaseGeographic.WKID property instead. E.g I'd expect the inSP.BaseGeographic.WKID to be 4269, and equal to defaultDT.InputSpatialReference.WKID. This isnt detailed in API reference for DatumTransformation though - I'll submit an issue to get this documentation updated with this information - thanks for highlighting it to us.

One thing I forgot to mention in my initial query: even though the shapes are drawn correctly, there’s still a bit of inconsistency. For example, when the zoom level is very high and I draw a rectangle or circle, the shape loads and draws again with the correct coordinates, but its position appears slightly off. When I hover over the area, it gives me the correct location, and due to the high zoom, the hover difference is minimal. However, the shape’s visual placement is still slightly off. From your info above, the geometry you're drawing on your map is not the same geometry as the one that you get back from the geometry editor, so I imagine there will be some differences here - if you try your same workflow but save & reload exactly the same geometry as you got back from the geometry editor, do you see the same discrepancy, or does the shape then appear exactly where you expect? Other things to look at would be if you have any reprojection happening in your workflow - different transformations can vary in their accuracy a little. You might find it helpful to read the following info if you're not already familiar with how data is reprojected - https://developers.arcgis.com/qt/spatial-and-data-analysis/spatial-references/#when-you-need-to-know-about-spatial-references, and this ref contains info on how the geometry of a GeometryEditor is returned with regard to spatial references which might help: https://developers.arcgis.com/qt/cpp/api-reference/esri-arcgisruntime-geometryeditor.html#geometry

@SWE Glad your shape is looking better. > the shape loads and draws again with the correct coordinates, but its position appears slightly off. I'm not sure there's enough information here to tell what problem you're seeing, but worth mentioning a couple of things in case these help. The geometry editor is not creating a geodesic ellipse, whereas you're recreating the shape as a geodesic shape, so you might see some differences due to that I'd expect - more noticable at smaller scales though. Also you've not mentiond how you're preserving spatial references throughout your workflow, so could there be some reprojection of your recreated shape happening?

Hi @SWE - (replying on behalf of Lucas as he's now out of the office for a while). It looks like you're recreating your geometry by passing in a value of 1.0 for the maxDeviation parameter to GeometryEngine.bufferGeodetic, and I'd guess this value could be the problem. This parameter is controlling how approximate the result is - i.e. how far from a "perfect" geodesic buffer the line segments of the result geometry are allowed to be - a smaller number will make a smoother geometry and a larger one will result in a more obvious set of straight lines. Have you tried experimenting with this value at all? If you don't want to calculate a specific deviation value that's suitable for your use case, you could try passing in NaN instead- this will calculate the result to have a maximum deviation of up to 0.2% of your buffer distance (the radius in your case), with a maximum of 0.01 meters, aiming to give a smooth looking geometry without excessive vertices. If your map scale is so large that a maximum deviation of 0.01 meters results in a rough looking geometry you may need to experiment further. Let us know if this helps.

@SatyaraySingh - if your map point is always WGS84, could this be because WGS84 is always magnetic north aligned anyway? If there's no difference then the method will always return 0. If you use a projected coordinate system that is not magnetic north aligned then I'd expect a non-0 result - for example, if have a point in British National Grid as below (WKID 27700), then I get a result of -0.984136. var bngPoint = new MapPoint(325847, 674007, SpatialReference.Create(27700)); var ConvergenceAngle = bngPoint.getSpatialReference().getConvergenceAngle(bngPoint);

Hi @MichaelDavis3 - I'm not sure on the details of the implementation, so I will see if I can get this confirmed for you.

> If I needed to find bearing from True North to a particular Mappoint. is there any method to do so? Hi @MichaelDavis3 - I think that theGetConvergenceAngle method on SpatialReference could be helpful here in figuring out a difference between True North and Grid North for a specific point: https://developers.arcgis.com/net/api-reference/api/net/Esri.ArcGISRuntime/Esri.ArcGISRuntime.Geometry.SpatialReference.GetConvergenceAngle.html

No worries, glad it's working for you now @StefanKallin 😀..

Hi @StefanKallin - can you describe the scenario where you're not getting the event? If you're using the default VertexTool, and have clicked/tapped to add a vertex - for example - I'd expect it to fire at that point, or any other time the geometry value changes (like when you start the geometry editor with an existing geometry object). However I wonder if your situation is that you want the event during a drag operation - for example in the middle of dragging/moving a vertex from one location to another using the VertexTool, or maybe during the initial creation of a circle or ellipse with the ShapeTool? I'd expect in both these cases that during the drag operation you dont get geometryChanged event on every mouse move increment of the drag operation, but it should happen when you release the mouse (or release the touch pointer if you're working on a touch device), as that's when the geometry property value is updated. Also same goes for the drag operation of a rotate or scale or move of a whole geometry or a part. If that is the specific case you're dealing with then we'd love to hear about your use case and perhaps you could post in ArcGIS Ideas for Native Maps SDKs about this requirement - we could consider enhancing the events in a future release.

Hi @jokerjoker - is there anything specific about the snapping in ArcGIS Pro which is essential for you? Do you need to be able to choose what part of a geometry (vertex or edge/segment for example) to snap to? Do you need to be able to adjust the tolerance? It's possible that we may add basic snap-to-feature functionality initially and then add future enhancements based on user demand, so it's great if we know which parts of snapping functionality are the most in demand from users like yourself - if you have specific use cases you could describe that's really useful (please feel free to message me directly if you prefer).

Hi @noodle - I'd also add another option, which might be useful if you don't want to stop the GeometryEditor after adding two points, but want you user to be able to continue to move existing points, and to be able to rotate, scale, and move the geometry. As @JenniferNery says you can monitor for the number of points in the polyline geometry. Once you have 2 points, you could get the current tool (I'm assuming you're working with the VertexTool here) and then change it's InteractionConfiguration.allowVertexCreation property to false. If you also want the user to be able to delete an existing vertex and re-add it, then ensure the config property is set back to true when the vertex number is less than 2.

Hi @jokerjoker - although there is not currently any snapping functionality in the ArcGIS Maps SDK for Kotlin GeometryEditor it is something that is on the roadmap for future releases. Do let us know what specific snapping functionality you're looking for when capturing geometry edits. Regards, Shelly

Hi @SokoFromNZ - There is not currently any API in Runtime (/ Native Maps SDKs) which can list out supported spatial references / coordinate systems, by area of use or otherwise. We do document all of the supported systems in a series of PDFs (found in the Downloads area of your ArcGIS Developers account page), which includes area of use information. However, that would be highly laborious to translate into code yourself. I don't see anything similar already mentioned in the ArcGIS Maps SDKs Native Ideas place - perhaps you could post the suggestion there along with your use case and workflow information, and we could monitor interest in this potential enhancement.

‎08-09-2023

Hi @ofirrosner , We don't have any specific plans to add more geodetic methods to GeometryEngine in upcoming releases, but perhaps you might like to post this request on ArcGIS Maps SDKs Native Ideas place where we can monitor interest in this enhancement. We are adding a few new GeometryEngine methods in an uncoming release, so this is a continuing area of development that we can consider enhancements for.
