Map Tile Server API

 

 

These maps and their tiles are generated from our map database and are delivered on API request to end-users. GeoJunxion uses a combination of methods that makes this service very fast and efficient. The map service comes with on-demand tile rendering rendering, often with smart-tiling, and custom styling. With smart tiling, all populated areas can be pre-rendered to fulfill super-fast response to map requests.

 

What does a map request look like:

https://<server address>/{z}/{x}/{y}.png?apikey=<key>

Layer projection: EPSG:3857

Legend:

  • Server address: tile server API address for tile requests.
  • {z} is the zoom level value
  • 0≤{x}<2{z}, 0≤{y}<2{z} is the relative grid position
  • Key: specific unique key provided by GeoJunxion for a particular distribution.

All content including names and geographic data presented are retrieved from the source Openstreetmap (OSM). While working with a versatile open source data set such as OSM, build by a community, one may encounter inconsistencies of data edits. GeoJunxion has put some effort in solving such occasions for the maritime boundaries, however, because it is impossible to continuously monitor and cover all inconsistencies some tiny pieces of maritime bounds may occur.

Slippy Map

The provided map tiles can be used in a modern slippy map web map application which let you zoom and pan around. With a slippy map, basically, the map slips around when you drag the mouse. More info regarding this kind of map, can be found here: https://wiki.openstreetmap.org/wiki/Slippy_Map. How are slippy map tiles converted back and forth from/to coordinates? The answer, in many programming languages, can be found here: https://wiki.openstreetmap.org/wiki/Slippy_map_tilenames.
