Following the docs results in:
Error: mapbox_gl_esri_sources__WEBPACK_IMPORTED_MODULE_4__.ImageMapService is not a constructor
at mapbox-gl.js:31:1

Edit: I see the docs are out of date, should be ImageService https://github.com/frontiersi/mapbox-gl-esri-sources/blob/master/src/main.js

https://github.com/frontiersi/mapbox-gl-esri-sources/blob/master/docs/src/pages/examples/ImageServiceBasic.vue#L10

Hey!

Using this library, how can we leverage the Aspect-Slope raster function from Esri in Mapbox?

I didn't find any docs or examples about it.

Thank you.

Hi @rowanwins

The identify request does not work when the queried layer has default visibility property as false ("defaultVisibility": false).

In this sample https://codepen.io/PedroNGV/pen/wvxgmOp :

• Elevation layer returns the identify output as expected;
• Slope layer does not return nothing.

The diference between both layers is:

• Elevation has Default Visibility: true;
• Slope has Default Visibility: false.

Looking at the request:
https://sigservices.icnf.pt/server/rest/services/BDG/LF_PT_RELEVO/MapServer/identify?sr=4326&geometryType=esriGeometryPoint&geometry=%7B%22x%22%3A-7.065627735444195%2C%22y%22%3A40.77396674193105%2C%22spatialReference%22%3A%7B%22wkid%22%3A4326%7D%7D&tolerance=3&returnGeometry=false&imageDisplay=1920%2C553%2C96&mapExtent=-7.082986992188637%2C40.77110672954365%2C-7.050028007813523%2C40.77830527567522&layers=show%3A14&layerDefs=false&time=false&f=json

I see layers=show:14

which came from
https://github.com/frontiersi/mapbox-gl-esri-sources/blob/master/src/DynamicMapService.js#L42
and
https://github.com/frontiersi/mapbox-gl-esri-sources/blob/master/src/DynamicMapService.js#L156

I've checked how esri-leaflet deal with identify requests, and it seems to use visible: (layers=visible:14) instead of show:
https://github.com/Esri/esri-leaflet/blob/daebcc8f69930a90b4ec726b0eb34fbe393d90af/src/Layers/DynamicMapLayer.js#L100

Changing https://github.com/frontiersi/mapbox-gl-esri-sources/blob/master/src/DynamicMapService.js#L156 to use visible:, the output already came as expected, both in Elevation and Slope layers.

Do you think this change should be applied?

Thanks!

Various Esri Services (name FeatureServer and MapServer) can be queried to return geojson which can then be displayed on a map.

To do this naively is quite simple, you can just pass in a query parameter &where=1=1, this gives you back all the data. The problem is that the response size could be really big depending on how many features there are.

A more sophisticated approach uses getting data on a per-tile basis, this is how esri-leaflet tackles it. This approach is alot more scalable as you only retrieve the geojson for the area you're looking at, and you can also adjust precision and simplicity depending on scale etc.
This would be awesome, but requires writing a custom-source for mapbox-gl, and this is somewhat undocumented, and would require a stack more code.

Choices choices....

Has anyone been able to use Mapbox and not tile wms, dynamic or image services?

Here is an example:

https://nowcoast.noaa.gov/arcgis/rest/services/nowcoast/forecast_meteoceanhydro_sfc_ndfd_time/MapServer/export?dpi=96&transparent=true&format=png32&layers=show:15&time=1680220800000,1680220800000&bbox=-12465110.272594094,5694899.676864316,-12465079.74257011,5694918.7861213805&bboxSR=3857&imageSR=3857&size=818,512&f=image

Hi,

I'm trying the Identify features from a Dynamic Map Service, and the identify output is shown even when the layer is disabled by the maplibre-gl-legend module. Here is a sample:

https://codepen.io/PedroNGV/pen/PoBWNpM

The expected behaviour would be the popup not be shown when the layer is disabled, like in the default popup (https://maplibre.org/maplibre-gl-js-docs/example/popup-on-click/).

Do you think this is a bug? Or just a misconfiguration?

Thanks!

Hi,

awesome library! Do you plan on providing TypeScript support and types at some point?

Could not find a declaration file for module 'mapbox-gl-esri-sources'.
Try `npm i --save-dev @types/mapbox-gl-esri-sources` if it exists or add a new declaration (.d.ts) file containing `declare module 'mapbox-gl-esri-sources';`
