can i create my own layer?

Question

Hi.

I want to have an overview of schools in a specific area (the municipality of Lyngby-Taarbæk, Denmark). If I use Google Maps (which I by all means wish to avoid), I can create my own map showing exactly the POI I need. I don't mind mind sharing my map of these POI. Is there a way that doesn't include installing and figuring out new software?

With regards

Jacob

To answer all of your questions in one go:

Use this Overpass Query:

[out:json][timeout:25];area(3602183062)->.searchArea;(node["amenity"="school"](area.searchArea);way["amenity"="school"](area.searchArea);relation["amenity"="school"](area.searchArea););out body center;>;out skel qt;
{{style:
    way[amenity] {
      text: name;
    }

    node[amenity] {
      text: name;
    }

   relation[amenity] {
      text: name;
    }

}}

It returns not only schools represented by nodes, but also those represented by ways or relations. The names get displayed by the little Mapcss at the end of the query.

The Vej (or Way) refers to the OSM object that is used to represent the object. It has nothing to do with the physical "street" object on which one drives.

Frederik's query only asked for schools represented by a node, so some of the schools you mention did not appear the answer, as they are represented by (closed) ways.

The query I link to uses a slightly different syntax. This is the new standard language of Overpass, but the XML-format in Frederik's answer is still supported.

Editing is pretty simple. First you have to make an account on openstreetmap.org. Then you see an edit button above the map openstreetmap.org. Follow the tutorial offered by the iD tutorial. You could also read LearnOSM

There is a query tool that you can use to find the objects in question. It is called "Overpass API" and can be conveniently accessed through the Overpass Turbo web site. Using Overpass to find the schools in Lyngby-Taarbæk requires that you first identify the OSM relation ID of that municipality - 2183062 - and then add 3600000000 to that number to use it in an Overpass query like so:

<osm-script output="json">
  <query type="node">
    <has-kv k="amenity" v="school"/>
    <area-query ref="3602183062"/>
  </query>
  <print mode="body"/>  
</osm-script>

(See it in action directly on Overpass Turbo.)

You can influence the look of the result within certain limits, see http://wiki.openstreetmap.org/wiki/Overpass_turbo/MapCSS. If you want more control over the look of the map, you should have a look at the UMap service which lets you draw stuff on the map and edit it. You can even export the query results from the above Overpass query and import them into UMap for editing, or directly link UMap and Overpass - but then of course you can't manually edit the result.

(Example for an editable UMap with the above data.)
