What service type is effective for speeding up ArcGIS Server maps using open standards?

The WMTS (Web Map Tile Service) is highly effective for speeding up ArcGIS Server maps by utilizing open standards. This service presents pre-rendered map tiles that can be requested and displayed as needed, significantly enhancing performance.

When using WMTS, the map is divided into tiles at various resolutions and served as individual images. This allows for quicker loading times since only the visible tiles are fetched, rather than re-rendering a full map every time the user pans or zooms. Additionally, because WMTS follows the OGC (Open Geospatial Consortium) standards, it promotes interoperability and integration with other mapping services and platforms.

In contrast, other service types like WCS (Web Coverage Service) are more focused on delivering raster data as continuous surfaces, which may not provide the same performance benefits for maps. Geodata services are designed for multi-user access to edit and update data, and they are not specifically designed for enhancing map display efficiency. Image services are useful for serving large datasets of raster images but may not deliver the same level of optimization for rendering maps as the tile-based approach utilized by WMTS.
