I am using Django, leaflet and openstreetmap.org to display the map in osm and topo formats. How to display just the map of a country. For example just display the map of Algeria? Thank you so much.
This trick can achieve what you need.
You can add a geojson file with the geometry of the country you want then customize the polygon to show just the country.
In the next link you will see a code example.

I'm using Mapbox gl for showing POI in using the geocoder. for some reason, the location of most of the poi is not accurate, because this marker is not getting placed on the POI. Is it possible to change the poi label style based upon the search result? I know using setLayoutProperty we can change all the poi label names but I want to change the specific poi name which comes out of the geocoder search result. Any help is much appreciated.
Adding more information, I'm creating a marker using the geocoder results, however, there were a good amount of restaurants whose marker is positioned away from the actual location. Maybe because of the incorrect coordinates. So the idea is to change the style of the restaurant name in the map instead of creating a maker, this will remove the marker floating around the wrong location.
My question is it possible to do such kind of styling or is there a way we can get more accurate coordinates. I could able to see using SetLayoutProperty for "POI_LABLE" we can change the styles of the name attribute. Is it possible to apply a filter here and change the style of the matched name?. Thanks for looking into this question.
Styles which use Mapbox Streets data show POIs from OpenStreetMap data unless you are in Japan, this is documented at https://docs.mapbox.com/vector-tiles/reference/mapbox-streets-v8/#data-sources--updates.
According to https://docs.mapbox.com/help/how-mapbox-works/geocoding/#source-data,
The Mapbox Geocoding API contains data sources from governments, open data projects, and private companies. In some cases, results from the Geocoding API may differ from Mapbox Streets or OpenStreetMap data.
So the POI results from the Mapbox Geocoder aren't guaranteed to be the same as those POIs shown on the map as they come from different data sources, hence won't always be in the same location and aren't linked with any form of ID.
I am new to leaflet. currently I am working on leaflet to render vector tiles. my application's requirement is that on click i should get features from map tiles in geojson format.
In Mapbox map.queryRenderedFeatures(e.point). I want to do exact same thing, but in leaflet. Please check here to check how mapbox is fetching features.
Please help.
Current Leaflet implementation does not supports querying rendered features. Hence switching to Mapboxgl
is there any posibility to show only Germany Country Borders and inner Data with Mapbox ?
I dont want the rest of the world displayed.
Thankx,
Markus
Yes. Use the Germany GeoJSON from http://code.highcharts.com/mapdata/. Upload it as a dataset, export it to tilesets, and then to a map as a layer. Delete all other layers.
I have a complete set of waypoints (beginning, end, every intersection) and I'd like to display this on a map. I don't want to use a routing service and it should be offline.
How can I draw polylines on a map so that they follow the curves of the road?
I'm using leaflet.
Could the data be extracted from a relational database(PostgreSQL) and then convert it into GeoJSON and display on the map by leaflet?
I can't use any paid services either.
Leaflet has a polyline object. MapBox has a nice example how to use it.
I think scai has given you a good example to practice.By the way you can also store the data in JSON format in PostgreSQL.Refer this documentation for more details.JSON Types
I'm using Leaflet and MapBox. I need to develop an api which will show certain city points with labels, and accordingly draw routes between them. I have BlueMarble tiles till certain zoom, and then MapBox Streets. What is the best way to realize that idea? Are circles and paths the best option? Thank you.
I am not sure that you need to create an API for what you want to do.

In the Leaflet tutorials it shows you how to create LineStrings and Points from GeoJson data. So with latitude and longitude coordinates for the Cities you can create Points and use LineStrings to create the routes and add a them as a GeoJson Layer to the map.
