Overview

These examples highlight Ultra's capabilities.

For examples of how to author OverpassQL queries, please reference the abundance of documentation on the OSM Wiki and elsewhere.

Add a title to a map

Use Ultra's HTMLControl to add a title to the map

Add a custom modal control to the map

This adds an info button that opens a modal clicked using Ultra's HTMLControl

Load GeoJSON with custom BBOX format

Load GeoJSON from the ohsome API using the east/west/south/north shortcuts.

ATP USPS Dropboxes

Load and style USPS Dropboxes from an All The Places dump.

Bike Infrastructure

Query and style bikelanes, bike parking, repair stations, and bike shops.

User Contribution Heatmap

Create a heatmap of your OSM mapping contributions.

Create a custom map style

Define an entire MapLibre GL style in a query document.

Create a glowing effect for points

Stack blurred circles to create a glowing effect for point data.

Use HTMLControl to add a link button to your map

This adds an info button that opens a link in a new window when clicked using Ultra's HTMLControl

Create a map of local landmarks

Select specific OSM elements by their wikidata IDs to make a map of local landmarks. This was a prototype of MapRVA's Open Landmarks project.

Minimalist Ski Map

Create minimalist ski maps of your favorite ski resort.

Prototype a 3D version of a style

Add 3D terrain and Buildings to OpenTrailStash using AWS-hosted DEM tiles and OpenMapTiles buildings

Overture Landcover with Hillshade

A basic natural background consisting of only hillshade and landcover.

Combine POI from Overture and OSM

Bike shops from the Overture Places dataset and OpenStreetMap combined in a single map using MapLibre symbol collision logic as a sort of run-time conflation.

Query OSM using QLever

Load OSM data from the QLever osm-planet dataset.

Tree Cover

Create stylized tree coverage from natural=tree nodes and natural=tree_row ways.

Viewing features at low zoom levels

Because of how MapLibre handles GeoJSON sources with geojson-vt, Ultra cannot implement a feature similar to overpass turbo's "show small features as points" feature. To work around this, query for the center of features instead of their full geometry.

Wikidata photo popup

Customize the query popup with a photo from wikidata loaded via hub.toolforge.org

Query Wikidata

Load Wikidata data from the Wikidata Query Service.

Find features within an administrative boundary

Use map_to_area to search for bus stops within Washington, DC.
