Static maps images (have the potential to) offer an easy way to embed maps on a webpage.

The idea is for web site developers to simply use an <img /> tag (in pure HTML or via a CMS). Its src attribute specifies the location of the map, the size of the image, the zoom level, the type of map, etc. When the webpage is displayed, the browser requests the image from the static map service and the map is displayed with no dynamic features, the same way as any other image.

Most of the options are open source, meaning you could host the service within your own webspace.

Approaches

  • Of course you can also grab a static map image by simply taking a screenshot; instructions for this vary between operating systems.
  • OSM's own Share panel's Image option also allows generating an image, but not as a permalinkable URL (for one-offs, and not for scripted use)

Proposal for unified Request Parameters

Besides varying in supported features each implementation has its own request parameter syntax. If you are planning to use one of those, read the documentation that comes with it.

Below you find a proposal for a more unified approach. Eventually some projects will adapt or implement compatibility modes.

OSM Scheme

  • lat
  • lon
  • zoom
  • layers
  • width
  • height


Google Static Maps API

  • center = latitude,longitude
  • zoom
  • size = width,height
  • format
  • maptype
  • markers
  • path
  • span
  • frame
  • h1
  • sensor

WMS Client getMap Request

  • version
  • request = getmap
  • service = mapnik, osma
  • layers
  • styles
  • srs = EPSG:3857 || EPSG:4326
  • bbox
  • width
  • height
  • format
  • bgcolor
  • transparent
  • exceptions

The schemes Google Static Maps API and WMS Client getMap Request are for compatibility reasons encouraging people the switch with little adjustments needed.
