Web Map Tile Server (WMTS)

The fastest, most efficient way to serve imagery on the Internet

(This page describes a stand-alone product component. See our OpenImageMap Imagery Tiling Platform for a complete turnkey solution.)

Overview

Since its introduction almost ten years ago, the Open GIS Consortium’s WMS (Web Map Server) specification continues to be one of the most successful of the OGC standards, with hundreds of different implementations in use across the Internet. The protocol allows clients to request maps in many different styles, sizes, projections and image formats. However this flexibility comes at the price of performance and scalability. Each map requested must be rendered by the server at considerable cost in processing power and time.

A faster, more scalable Web Map Service

To address this issue, CubeWerx offers a Web Map Tile Service (WMTS). This service, now an OGC standard, works by subdividing the map space into a set of pre-generated image files (tiles), which can then be rapidly returned to a client application, instead of creating a new map for each request. Google Maps is the most well-known example of such a service, however the CubeWerx solution achieves the same performance characteristics using non-proprietary technology. The service supports both a traditional web service interface as well as a REST option, allowing it to be easily integrated into a wide array of Web 2.0 applications. An intelligent tile generation and caching mechanism minimizes storage requirements by creating tiles on-demand, and caching them for subsequent requests, so only those tiles which users actually ask for exist on physical storage.

The tile creation process is backed by CubeWerx’ comprehensive image processing and symbology engines, allowing tiles to be created using OGC Styled Layer Descriptor (SLD) documents. Multiple tile sets may be created from the same data, to respond to different symbology or map projection requirements.

Key Features

  • Full REST and KVP interfaces for flexible and rapid client integration
  • Supports the creation of multiple styled tile sets for the same base data
  • Tiles can be generated at any set of scales required, and new scales can easily be added later
  • JOP (JPEG or PNG) tile image format delivers the most efficient image format required for any given request
    • Intelligent on-demand creation and caching of tiles to minimize disk storage requirements
    • Tiles may be created in hundreds of spatial reference systems profiled under EPSG projections and datums and allows users to define custom projections
    • Region-based updating of tiles allows new imagery to be added, or tiles removed and the tile set rebuilt in a matter of seconds
    • Full integration with our security module to provide complete data set or region-based access control capability
