Javascript API

DeveshKhosla — Wed, 08 Jan 2020 20:42:07 GMT

Can we create API locally server not on the ESRI server.

ie. i have https://tiles.arcgis.com/tiles/Ezk9fcjSUkeadg6u/arcgis/rest/services/OPCNM/VectorTileServer

I want to create this api

https://localhost:5272/Tiles_VectorTileServer

Are you asking if you can create a tile service outside of ArcGIS Server? You mentioned the API, which can be hosted locally, but it doesn't sound like this is what you're looking to accomplish.

Yes. Can we create tiles service outside ArcGis Server?

I am looking for Tiles , feature layer, etc outside ArcGis server.

When it comes to feature layers, you're not bound to ArcGIS Server. For example, check-out ArcGIS API for JavaScript Sandbox

This sample uses GeoJSONLayer, but you can also create a FeatureLayer from the graphics returned by a geojson call... it's just a little more work. Let me know if GeoJSONLayer isn't something you can use and I'll supply a sample for converting GeoJSON into a FeatureLayer.

You can also create layers using CSVs - ArcGIS API for JavaScript Sandbox

For tiles, can you use ArcGIS Online? Also, have a look at this - https://community.esri.com/thread/184269-is-it-possible-to-render-mapbox-vector-tiles-pbf-from-a-custom-tile-server

Thank you so much for reply.

Firstly can you provide me sample code to convert GeoJson to Feature layer.

Second, I have mostly NDVI images they are tiff files. That's why i was using tiles to display my Tiff files.

If you have any other way we can display tiff image. Without ArcGis Server.

Thirdly,I was thinking about postGresql to save these layer.

Thank you. I want display data without using ArcGis Server.

ArcGIS API for JavaScript Sandbox

How I can create tiles or feature layer Api on my own server.

Do you have any sample code.

Here's another one of my threads that has code on how to convert GeoJSON to FeatureLayer:

Polygon renderer issue fixed in v4.13 - when's the release date?

...let me see if I can create something for you...

Are you asking how to publish and host tiled layers and feature layers on a non-ArcGIS server? Honestly, I'm not sure how to do that. The samples above show how to consume resources without using ArcGIS Enterprise. Some layers can be hosted and consumed (like VectorTileLayer, WebTileLayer, WMS, and WMTS) from a third-party server, and some cannot (e.g. MapImageLayer, FeatureLayer). For the FeatureLayer, you could still create one programmatically, but I think only ArcGIS Enterprise can host an actual FeatureLayer. Soon, the 4x version of the JS API will support WebFeatureLayer (which is currently supported at 3x).

Your best bet is to:

1) review documentation for third party servers, like GeoServer, and OGC standards

GeoServer

Web Map Service | OGC

2) review our API reference for how to consume such layer types

FeatureLayer | ArcGIS API for JavaScript 4.14

VectorTileLayer | ArcGIS API for JavaScript 4.14

WebTileLayer | ArcGIS API for JavaScript 4.14

WMTSLayer | ArcGIS API for JavaScript 4.14

WMSLayer | ArcGIS API for JavaScript 4.14

ArcGIS Enterprise is the most robust tool for publishing raster imagery services. However, open source software may also publish in the supported formats that Noah Sager shared above.

Devesh Khosla What is your hangup for why you want an alternative to ArcGIS Enterprise? We may be able to help discover a solution that still fits your goals.

Noah,

The thread I linked earlier - Is it possible to render mapbox vector tiles (pbf) from a custom tile-server - has information on doing this successfully using PostGIS, so it's not just in the realm of theory.

Re: Javascript API

ChrisSmith7 — Sat, 11 Dec 2021 12:14:23 GMT

So, for example, check-out:

https://developers.arcgis.com/javascript/latest/sample-code/sandbox/index.html?sample=layers-vectortilelayer-json

In this sample, you can see it closely aligns with the discussion in Is it possible to render mapbox vector tiles (pbf) from a custom tile-server, where this chunk of code is in the Esri sample:

url:
"https://basemaps.arcgis.com/arcgis/rest/services/World_Basemap_v2/VectorTileServer",
type: "vector"‍‍‍

...to simplify the other aspects, you would need the source (your server) to supply the expected JSON here - to quote:

You now need to serve your actual (pbf) tiles using the url pattern specified. In this example, that would be https://ourhost/oursource/{z}/{x}/{y}.pbf.

Beacuse i want to display offline data. Api data only on my machine that's why I am looking for alertnative.

Would it make sense to create an app using an ArcGIS Runtime SDK with the local server capability? Direct read, write, and use of local raster, vector, and myriad other data options.
