This page contains documentation for the cartographer project. This project is still in development and is prone to changes. This project uses the codename Doogle or Doogle Maps sometimes.


Map Creation

Old School RuneScape

The map for OSRS are created using modified version of the RuneLite MapImageDumper script. It uses the game cache as the source for the maps. This provides easily updatable maps. The code for this can be found at: (currently not available)

This script creates map regions at different resolution levels:

  • Map region Zoom 0.png

    Zoom level 0, 64x64px, 1px per game square

  • Map region Zoom 1.png

    Zoom level 1, 128x128px, 4px per game square

  • Map region Zoom 2.png

    Zoom level 2, 256x256px, 8px per game square

  • Map region Zoom 3.png

    Zoom level 3, 512x512px, 16px per game square

These map regions include ground color, roads, buildings, doors, walls, trees and other objects. Icons are not included in these renders.

There map regions are then processed into maptiles that can be used for viewing the map. These tiles are all 256x256px but created using different map regions. This process uses ImageMagick (montage and convert) to combine and split image to create the desired result. This process is automated using a Bash shell script:

  • Map tile Zoom -1.png

    Zoom level -1

  • Map tile Zoom 0.png

    Zoom level 0

  • Map tile Zoom 1.png

    Zoom level 1

  • Map region Zoom 2.png

    Zoom level 2

  • Map tile Zoom 3.png

    Zoom level 3

These tiles are directly used by Leaflet to display the map.

RuneScape 3

Similar process as OSRS.

Data Collection

The map uses varies sources of data to populate the map. A list can be found here.

Old School RuneScape

Data Name Data Source Processing tool Notes
Map tiles Game Cache RuneLite See: above
Map icons Game Cache, Manual (user defined) RuneLite
Map bounds (MapID) Game Cache, Manual (user defined) RuneLite
Map labels Game Cache, Manual (user defined) RuneLite
NPC locations RuneLite, Manual (user defined) ? Not implemented
Path data Game Cache RuneLite?
Map Area's Manual (user defined) GeoJSON Not implemented
Item spawn locations Game Cache?, Manual (user defined)? GeoJSON Not implemented
Quest steps Manual (user defined) GeoJSON Not implemented
Teleport locations Manual (user defined), Game Cache?, RuneLite? GeoJSON Not implemented, possible source: RuneLite, Manual, Manual 2
Map links (doors, portals, ...) Game Cache, Manual (user defined) ? ?

Map Implementation

The map implementation for OSRS and RS3 use the same codebase. This codebase can be found here: (currently not available)

The map implementation uses Leaflet for the map implementation and Gulp for project compelation.

Map tiles

The map tiles are available under the path: maps/{mapID}/{z}/{p}_{x}_{-y}.png

Definition lists
mapID
the map bounds (0=RuneScape Surface, 1=Acient Cavern), mapID's smaller then 10000 are exported from game cache, mapID's larger then 10000 are user defined
z
zoom level, supported zoom level from -3 (zoomed out) to 3 (zoomed in), map can zoom to level 5 but this just scales the zoom level 3 images.
p
planes, the floor levels, these go from 0 to 3, dungeons and basements are displaced on the map and support same planes (see mapID)
x
x-coordinate of bottom left corner of map this changes depending on the zoom level. Zoom level 2 correspond with game coordinates*
y/-y
y-coordinate of bottom left corner of map this changes depending on the zoom level. Zoom level 2 correspond with game coordinates*

Loading data

To better support different datasets, iconsets and layers most of the data is loaded from JSON files the main file that is loaded is 'dataloader.json'. This file contains the different mapID's, icon sets and layers.

Loading data follows the following structure: (this might change a little bit)

  1. load dataloader.json
    • create dataproviders
      • dataprovider -> IconProvider (async)
        • create iconclasses
        • create iconlist
          • icon -> filename (files not downloaded until used)
    • wait for dataproviders to be downloaded and created
      • baseMaps -> BaseLayerBuilder
      • overlayMaps -> IconLayerBuilder
        • dataSource -> download and parse geojson (async)
      • add baseMaps and overlayMaps added to map controllers
  2. baseMaps displayed
  3. overlayMaps displayed when ready

The file below gives more info about this format, as json does not support comments we added '//' before a line comment. (Note: This is not a valid json file) 

{
  "datasources":[ // a list of all data sources, currently only for iconsets
    {

Example of overlayMaps.dataSource file: 'MainMapIconLoc.json' Note: these files use the GeoJSON file format with added 'properties' fields. To create these file tools like http://geojson.io could be created to make this easier.

        ]

    // for more features look in GeoJSON standard, other features include: Polygon, MultiPoint, MultiLineString and MultiPolygon
