The example on mapbox.com returns nice information on the hovered feature, also the fill-color https://docs.mapbox.com/mapbox-gl-js/example/queryrenderedfeatures/
The fill-color returned looks like this:
"feature": {
"type": "Feature",
"layer": {
"id": "data",
"type": "fill",
"source": "jsx-source-1",
"paint": {
"fill-color": {
"r": 0.6398494117647059,
"g": 0.26332078431372546,
"b": 0.1670227450980392,
"a": 0.7
}
},
"layout": {}
},
"source": "jsx-source-1",
"state": {}
},
The label "r", "g", "b", "a" seems to be rbga color code, but the returned values are not. What is this?
Any idea how to convert this into rgba, hex, hsl?
I figured it out. Multiply the single values by 255 in order to get an rgb code, leave the "a" (alpha) as it is.

I am trying to find a substring of a string as a part of an activity in ADF. Say for instance I want to extract out the subsctring 'de' out of a string 'abcde'. I have tried:
#substring(variables('target_folder_name'), 3, (int(variables('target_folder_name_length'))-3))
where int(variables('target_folder_name_length')) has a value of 5 and variables('target_folder_name') has a value of 'abcde'
But it gives me: Unrecognized expression: (int(variables('target_folder_name_length'))-3)
On the other hand, if I try this: #substring(variables('target_folder_name'), 2, int(variables('target_folder_name_length'))-3)
This gives me: 'int' is a primitive and doesn't support nested properties
Where am I going wrong?
Use indexof. See my example below:
#substring(variables('testString'), indexof(variables('testString'), variables('de')), length(variables('de')))
Output of 'result' variable:
Since your preceding values are static, you can use below dynamic expression to achieve the substring value as per your requirement.
#substring(variables('varInputFolderName'), 3, sub(length(variables('varInputFolderName')), 3))
Where varInputFolderName = String = abcde as per this sample.
Here is the pipeline JSON payload for this sample. You can play around with it for further testing.

i'm new to the topic MongoDB and have 4 different problems importing a big (16GB) file (jsonl) into my MongoDB (simple PSA-Cluster).
Below attached you will find a sample entry from the mentiond JSON-Dump.
With this file which i get from an external provider I actually have 4 problems.
"hotel_id" is the key and should normally be (re-)named as "_id"
"hotel_id" should not be treated as string rather than as Number
"location" is not properly formatted (if i understood correctly the MongoDB Manual) as GeoJSON as it should be like
"location": {
"type": "Point",
"coordinates": [-93.26838,37.15845]
}
instead of
"location": {
"coordinates": {
"latitude": 37.15845,
"longitude": -93.26838
}
}
"dates" can this be used to efficiently update just the records which needs to be updated?
So my challenge is now to transform the data according to my needs before importing the data or at time of import, but in both cases of course as quickly as possible.
Therefore i searched a lot for hints and best practices, but i was not able to find a solution yet, maybe due to the fact that i'm a beginner with MongoDB.
I played around with "jq" to adjust the data and for example add the type which seems to be necessary for the location (point 3), but wasn't really successful.
cat dump.jsonl | ./bin/jq --arg typeOfField Point '.location + {type: $typeOfField}'
Beside that i was injecting a sample dump of round-about 500MB which took 1,5 mins when importing it the first time (empty database). If i run it in "upsert" mode it will take round-about 12 hours. So i was also wondering what is the best practice to import such a big JSON-dump?
Any help is appreciated!! :-)
Kind regards,
Lumpy

Is it possible?
This tells me it is, but dont know why it defines and API key.
but I cannot get it to work with react-map-gl StaticMap class. The property I can see from that class is just mapStyle which would take a standard Mapbox vector tiles path/name. Does it take an object? My code does not give me an error or show the tiles I request.

UPDATE: Mapbox changed their license in 2.0 so the accepted answer is correct for versions < 2.0. Mapbox > 2.0 will complain if no access_token is provided.
The trick is in the style that's used. A style is a JSON object, whose specification you can read more about here. You can generate custom styles using tools such as Maputnik, a visual editor that generates style-compliant files for use in MapboxGL maps. Once you have an appropriate style generated, you can use it in React Map GL.
Here's what the basic component would look like, as altered from the example in the Github repo:
<ReactMapGL
mapStyle="https://s3.amazonaws.com/cdn.brianbancroft.io/assets/osmstyle.json"
{...this.state.viewport}
onViewportChange={viewport => this.setState({ viewport })}
/>
Note that this is just an abstract example. The tile loads from OSM here are a bit too slow to be useful in production. But it should illustrate how to make maps without relying on the services side of Mapbox.
Is there a way to extrude the height of mapbox Point on the map?
Having the following example:
map.addSource("markers", {
"type": "geojson",
"data": {
"type": "FeatureCollection",
"features": [{
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [14.422063225409431,50.08273361716846]
},
"properties": {
"height": 12,
"base_height": 10,
"title": "Mapbox DC",
"marker-symbol": "spaceti-maintenance"
}
}, {
"type": "Feature",
"geometry": {
"type": "Point",
"coordinates": [14.421896271941648,50.08259946060207]
},
"properties": {
"height": 12,
"base_height": 10,
"title": "Mapbox SF",
"marker-symbol": "spaceti-maintenance"
}
}]
}
});
map.addLayer({
"id": "markers",
"source": "markers",
//"type": "symbol",
"type":"fill-extrusion",
// "layout": {
// "icon-image": "{marker-symbol}",
// "text-field": "{title}",
// "text-font": ["Open Sans Semibold", "Arial Unicode MS Bold"],
// "text-offset": [0, 0.6],
// "text-anchor": "top"
// },
"paint": {
// See the Mapbox Style Spec for details on property functions
// https://www.mapbox.com/mapbox-gl-style-spec/#types-function
"fill-extrusion-color": "#424242",
"fill-extrusion-height": {
// Get fill-extrusion-height from the source "height" property.
"property": "height",
"type": "identity"
},
"fill-extrusion-base": {
// Get fill-extrusion-base from the source "base_height" property.
"property": "base_height",
"type": "identity"
},
// Make extrusions slightly opaque for see through indoor walls.
"fill-extrusion-opacity": 0.90
}
});
am I able to use both layout and paint properties of the layer assuming that I want to have marker with custom icon + extrusion height? I am building indoor navigation with multiple floor, that is the reason.
It's not possible at this time to extrude points, however, you can convert these to (small) circles and extrude them based on your values. Looks like some similar requests for point cloud support is here:
https://github.com/mapbox/mapbox-gl-js/issues/3450 so you may be able to follow the progress should it makes its way into new releases.
I am trying to use Mapbox to calculate the duration between two locations however the examples here are incomplete (at least with my limited experience). I would like to connect to this API using server-side Java, however I can't even get a basic example working in javaScript, Python or simply in the address bar in my browser.
I can get an example working in my browser using this url and substituting in my API key:
https://api.mapbox.com/geocoding/v5/mapbox.places/Chester.json?country=us&access_token=pk.my-token-value
However I can't get a similar example working with the distance API. The best I can manage is something like this:
https://api.mapbox.com/distances/v1/driving/[13.41894,52.50055],[14.10293,52.50055]&access_token=pk.my-token-value.
But I have no idea how to format my coordinates as I can't find a single example.
Has anyone been able to get this working. Ideally in Java, but client-side JavaScript or a valid url would be a great start.
I should also add that I can't get the JavaScript or Python ones working as they rely on external librarys that aren't referenced anywhere in the documentation!.
Thanks in advance.
Looks like you can provide a list of 2 or more semi-colon separated coordinates:
https://api.mapbox.com/optimized-trips/v1/mapbox/driving/13.41894,52.50055;14.10293,52.50055?access_token=pk.your_token

I don't know if this is better now, but I had to work through it right now and can give you this example
curl "https://api.mapbox.com/directions-matrix/v1/mapbox/driving/9.51416,54.47004;13.5096410,50.0716190;6.8614070,48.5206360;14.1304840,51.0856060?sources=0&access_token={token}"`
This will return the following json for driving durations. I made use of the sources attribute, which is my search lng/lat and all other points are places in my database.

Adding the annotations=distance parameter to the url will return the distances instead of the durations if you need that.
