I haven't tested this out, but I wonder if actually using WGS84 (4326) for the source point might help? view.on("click", function(event){ console.log(event.mapPoint.longitude,event.mapPoint.latitude); const WGS84 = new SpatialReference({ wkid: 4326}); const NAD83 = new SpatialReference({ wkid: 26912 }); let point = new Point({ spatialReference: WGS84, x: event.mapPoint.longitude, y: event.mapPoint.latitude }) projection.load().then(function(){ // const transformations = projection.getTransformations(WGS84, NAD83); // console.log(transformations); point = projection.project(point, NAD83); console.log(point); }); });   ...

Do you have a simple CodePen showing the issue? ... View more

You import the class Point and then redefine this variable in your code to an object instance.  Try these changes:   const myPoint ={ type: "point", longitude: props.data[23], latitude: props.data[24] }; const pointGraphic = new Graphic({ geometry: myPoint, symbol: simpleMarkerSymbol });       ...

Not sure what the question is, but you should be able to find the interior ring by using the isClockwise(...) method. ... View more

Sorry, I misinterpreted the use case.  I think that using a self-hosted resource proxy as described in the 'Application login' section would be an option.  The calls to the secure service from the public app would go through the proxy. ... View more

I normally share content to a group only and then create an item for my app, register it, and use OAuth in the application to access the services, and you can even provide a referrer for your app. ... View more

Do you have a CodePen where we can experience the issue? ... View more

Could you maybe create a CodePen where a few of the locations from the csv are created manually? ... View more

I wonder if something like this might help? view.goTo({target: polygonGraphic.geometry.extent.center, zoom:16}).then(()=>{ graphicsLayer.addMany([polygonGraphic, ptGraphic]); });   ... View more

Sounds like you might be looking to create the convex hull around a set of points?  Maybe something similar to this might work for your needs: https://codepen.io/john-grayson/pen/NWbLGaR If not, maybe you could provide a CodePen using your data so we can see what might be going on? ... View more

Check out all of the available renderers and yes, maybe the RasterColormapRenderer or RasterShadedReliefRenderer might be better fits for what you need. ... View more

The doc says "The RasterColormapRenderer is only available if a color map is present in an ImageryLayer or ImageryTileLayer." but the service you are trying to use doesn't have a color map defined.  Instead, you can use a ClassBreaksRenderer to achieve what you'd like; check out this CodePen: https://codepen.io/john-grayson/pen/RwoJbPq  ...
