Request URLs

Request by Distance from Point

Load points a given distance from a latitude,longitude center with the llcenter variable:

olpcMAP.net/json?llcenter=42.356261,-71.05957&km-distance=30

Using Yahoo Maps + Where On Earth ID, you can set the center to be almost any placename:

olpcMAP.net/json?center=Boston,MA&km-distance=30

Using a map marker as the central point:

olpcMAP.net/json?id=336003&km-distance=600

The URL above loads points within 600 kilometres of the map marker at http://olpcMAP.net?id=336003

Request by Area

Load points within a box (use format north,east,south,west):

olpcMAP.net/json?llregion=20.38154,-69.579162,17.555734,-74.98993

Using Yahoo Maps + Where On Earth ID, you can set the region to almost any placename:

olpcMAP.net/json?region=Mongolia

  • pt - a array of two decimal numbers with format [ LATITUDE , LONGITUDE ]
  • icon - string URL to the marker's preferred icon. Values such as an empty string or "DEFAULT" can be any icon
  • details - string - text description of this point; may include HTML links, ordered lists, and unordered lists
  • photo - string URL to a photo connected to this marker; empty string means that none is known
