The following table offers a comparison of WMS and WMTS.
WMS vs WMTS| WMS | WMTS |
|---|
| More supported | Lower degree of support |
| Loads imagery as a single, large file | Loads tiles |
| Slower to load | Quicker to load |
| More supported projections | Less flexibility in terms of supported projections |
| More compatible with on-prem apps | More compatible with web apps |
WMTS is similar to the Nearmap Tile API; so, you may want to consider that as an option.
