Using Overpass queries to support mapping bench inscriptions

نُشِر بواسطة Leigh Dodds في 10 مارس 2021 باللغة English

I just added a new query to OSM queries called Mapping Bench Inscriptions.

It illustrates how even a simple OverpassQL query coupled with some conditional MapCSS styling can produce a nice map that can guide a local survey.

In this case its focused on mapping public benches and adding inscriptions and photos to OpenBenches.

There’s a more detail in the query description, but in brief it highlights benches that:

  • don’t have a backrest tag (I see Street Complete also features this as an improvement)
  • have a backrest but no inscription - some benches do and in some locations, particularly along the UK coastline, many do
  • those that have inscriptions but aren’t linked to OpenBenches
  • ..etc

Hopefully both a useful query and an nice illustration of MapCSS at the same time.

Announcing OSM Queries

نُشِر بواسطة Leigh Dodds في 6 مارس 2021 باللغة English

This is a short diary entry to announce the publication of a project I’ve been working on for the last month or so called OSM Queries.

It’s a website containing a small, but growing, collection of useful Overpass API queries. This includes a 26 part tutorial that covers most of the core features of the language and a syntax reference.

The website is generated using an open source tool that can generate HTML pages from a collection of Overpass queries.

For more details, read my blog post announcing the project.
