With these resources, you can create your own local disk-based cache of any WMS server, and use the result in any WMS-C supporting client, like OpenLayers, or any TMS supporting client, like OpenLayers and worldKit. In the simplest use case, TileCache requires only write access to a disk, the ability to run Python CGI scripts, and a WMS you want to be cached. TileCache provides a Python-based WMS-C/TMS server, with pluggable caching mechanisms and rendering backends.

TileCache TileCache is an implementation of a WMS-C compliant server made available under the BSD license by MetaCarta. It is a middle-man between existing web map servers (like MapServer or GeoServer) and web map clients such as OpenLayers and GoogleEarth.

MapProxy is an open source technology used to create and serve up map caches.
#Mapproxy seeding full#
MapProxy works like a simple tile cache, but also offers many new and innovative features like full support for WMS clients. It caches, accelerates and transforms data from existing map services and serves any desktop or web GIS client. MapProxy MapProxy is an open source proxy for geospatial data. How? Consuming WMS and chopping it up into tiles Stored in accessible directory to be returned to client Application requests handled by cache utility Projection Location Tile size Image format Projections / Reprojection Most caches are created in a defined projection, but some utilities can reproject tiles (mapproxy). Transparency Transparency is used for overlaying tiles on top of other tiles and for sliding/transitioning effects. Setting tiling schemes for ArcGIS Server vary greatly than the other options we will review.Ĭaching Terms & Concepts Image Types Cached map tiles can be created/requested in different image formats. Pros: Avoid duplicating the labeling of features that span more than one tile Usually quicker for the WMS backend to generate one large image rather than many small ones Cons: Since the metatile is larger, it is slower to render than any individual tile Memory consumptionĬaching Terms & Concepts Tiling Schemes Tiling schemes allow for definition of scale levels, tile size and sometimes coordinate system. Seeding actions can be scripted, generated on-the-fly (user requests) or manually created.Ĭaching Terms & Concepts Metatiling A metatile consists of several tiles combined into one larger tile.
