Map Creation[edit source]

Old School RuneScape[edit source]

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:

This script creates map regions at different resolution levels:

These map regions include ground colour, 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:

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

Layering Creation[edit source]

Combining of tiles to create zoom layer 2 and 3 tiles and names

Combining and splitting images for use in Leaflet we have different zoom levels: 3,2,1,0,-1,-2,-3 The map scales exponential (2^x) for each zoom level. This is the same as most slippy map systems / GIS systems. It comes down to, if you zoom in each tile splits into 4 pieces, if you zoom out each tile is a combination of 4 pieces.

So zoom level 4 (400%) is created by splitting the image into (2^2)*(2^2)=16 images of 256x256 like this (but this is not used on our OSRS maps):

 0  1  2  3
 4  5  6  7
 8  9 10 11
12 13 14 15

At zoom level 3 (200%) is created by splitting the image into (2^1)*(2^1)=4 images of 256x256 like this:

0 1
2 3

Zoom level 2 (100%) just the same image (2^0)*(2^0)=1 image. (that is why in the script zoom level 2 just copies all the images (that are in the range we are working on). This is the same size as a region in OSRS.
Zoom level 1 (50%) is created by combining 4 images (128x128) to create a 256x256 image.
Zoom level 0 (25%) is created by combining 16 images (64x64) to create a 256x256 image.

RuneScape 3[edit source]

Similar process as OSRS.

Data Collection[edit source]

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

Old School RuneScape[edit source]

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[edit source]

The map implementation for OSRS and RS3 use the same codebase. This codebase can be found here: For the wiki we use a modified version of the Kartographer extension. This codebase can be found here:

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

Map tiles[edit source]

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

Definition lists
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. Map ids can be found at RuneScape:Map/mapIDs
version numbering for when a map has been updated. (in format: YYYY-MM-DD_{1-9}, with the last digit being the update of that day, usualy 1 )
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.
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-coordinate of bottom left corner of map this changes depending on the zoom level. Zoom level 2 correspond with game coordinates*
y-coordinate of bottom left corner of map this changes depending on the zoom level. Zoom level 2 correspond with game coordinates*

Loading data[edit source]

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

Config files[edit source]

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)

Map Overlay (icons, markers, shapes)[edit source]

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 could be created to make this easier.
