Hi @AddisonShaw, This functionality seems to have more support through the ArcGIS JS SDK, but wondering if there are any recommendations on usage within Leaflet. That's right, for everything with the exception of Esri cloud-hosted APIs that's usually the case. I'm wondering if there is more official support, or examples. I'm sorry, but as far as I know there is no official support for this and it is not planned to be 😔. But maybe we can get revitalize this plugin with community contributions. A few years ago I had to do the opposite, convert a websocket to a Stream services to be consumed by the Maps SDK for JS, so we had to build a WebSockets wrapper too (but in this case for Node.js). Related to this I recently I heard from @RichGwozdz  about Koop that: Output plugins can now use the pullStream method, so long as the linked providers include a getStream method. Docs forthcoming. I hope this helps, Raul   ... View more

Hi @AbhishekSrivastava2, regarding to this: ...Please bear with me. I don't have any money to buy arcgis. so please help me how can I achieve that I am trying to do. Or perhaps is there a way I can install a "free" tool on my Mac which will import this CSV and export another one with lat/long?... I just wanted to let you know that as a developer, you can also create a free account with a generous free tier (+$300/month currently) 😉, and with that soon you will be able to use the new outdoors basemap that was presented a few weeks ago which I think will fit pretty well that dataset 😁. And remember you can use it with our Maps SDK for JS to build cool visualization like this hiking map: Or any of the other open source libraries (Leaflet, MapLibre, ...) I hope this helps! ...

Hi @DanielDormont  I just read "Evaluating the Performance of Three Popular Web Mapping Libraries: A Case Study Using Argentina’s Life Quality Index" (compares Leaflet, Mapbox GL JS and OpenLayers) and remembered me this thread: ...And leaflet does work with WebGL, via esri-leaflet-vector, doesn't it? In fact that's something I've been wondering. Since we already use esri-leaflet-vector to show vector basemaps, is there not a way to use that same technology with feature layers?   Spoiler of the conclusions 😜: I will see if I can do my own research and include the ArcGIS API for JS too to the equation 😉, it would be nice to have a rigorous analysis considering them all and different visualization types. ...

Would you mind to provide more details?? There are also some apps to report issues on geocodes, basemaps and imagery that might be helpful. ... View more

Thank you all for your generosity and wiliness to help other users ❤️!!!! I hope I have the opportunity thank you in person soon 😊. ... View more

Thanks Rene for your help here 😊. BTW: sorry I tried to move the whole thread to this forum but apparently I did it wrong ^_^''. Just in case, and for context, this is the original question.   ... View more

I'm sorry @RYANCARL I didn't see this message. I hope the saying "better later than never applies here", at least if this isn't helpful for you anymore maybe it would be for someone else in the future: I think setDefaultRequestOptions have to be used like this: setDefaultRequestOptions({ // only accepts iRequestOptions params // authentication: ..., // credentials: ... // ... params: { // for additonal parameters use IParams agent: new https.Agent({rejectUnauthorized: false}), } }); I also recommend to use the repo issues to contact the maintainers if you don't help a response soon enough in here. I hope this helps, Raul ... View more

Sorry @TraceyBelle1 for the huge delay, I have no experience or access to Alteryx so I can not help you here. I can't find useful content using the search functionally either. I would try Koop if you are trying to access data hosted in Alteryx from ArcGIS products. If you are still interested on this maybe we can make a quick call so you can show me how Alteryx works and we can figure out a way to do it. ... View more

In my spare time I have started learning Dark and Flutter and I have been playing around with some existing open source packages trying to load ArcGIS basemaps: https://github.com/hhkaos/flutter_arcgis_basemaps I just wanted to share it in case anyone is interested on this, or is willing to collaborate to understand why this is not fully working. I will try to find some time to experiment with other packages too. ... View more

Sorry @DanielDormont for the delay! And leaflet does work with WebGL, via esri-leaflet-vector, doesn't it? In fact that's something I've been wondering. Since we already use esri-leaflet-vector to show vector basemaps, is there not a way to use that same technology with feature layers? I don't think there is an easy way. As you can see vector basemaps relies on maplibre-gl-js, and basemap tile services and feature layers services are very different. esri-leaflet-vector, but it would be better to ask in the repo.  I guess by "generic" I just meant that Leaflet can pull data including basemaps from any source; we have some customers who have their own custom data sources they want to use. 🤔... did you know that the JS API can also be used with any custom data source? I mean, there are some standard layers (GeoJSON, CSV, KML, WFS, ...) , and if none of them fit, you can also do it by drawing directly in a GraphicsLayer (in memory) or populating a FeatureLayer using an array graphics (example). In fact, we even have a few applications where the coordinate data aren't geographic at all, and we use https://leafletjs.com/examples/crs-simple/crs-simple.html to display them.  I agree that for use cases like this one I wouldn't use the ArcGIS Maps SDK for JavaScript either :). I hope you have a happy new year eve!! 🥳 ... View more

Hi @DanielDormont , There are multiple optimizations been done behind the scenes. @JeremyBartley explained some of them on Behind the scenes, What the JS API and ArcGIS do for you. But in summary ArcGIS API for JS use WebGL (Leaflet doesn't) plus the ArcGIS API for JS make use of all the optimizations included in the Feature Service to reduce the data transferred and produce faster responses (tile caching, PBFs encoded responses, geometry quantization, etc.) <- and as far as I know, the Esri Leaflet FeatureLayer.js doesn't as can be seen here: There you can see how Esri Leaflet request a GeoJSON from the service, plus every time you zoom in & zoom out send a bunch of requests to retrieve only the geometries needed (but do not cache, compress or simplify them) <- it would be great if someone in the community would open a PR to help improve it (but I think there are pretty complex optimizations in the JSAPI that wouldn't be easy to replicate). In my application we use Leaflet just because it's a bit more generic Interesting, what do you mean by more generic? Is there anything we could ask the JSAPI team to do to make it more generic? we were already familiar with it before we began integrating with Esri, but we have been running into similar performance issues displaying complex Feature Layers That's a common situation. Let me know if there is anything else we can do to support you or make your life easier learning how to integrate with ArcGIS. Cheers, Raul ... View more
