OneAtlas Basemap provides access through a range of different protocols. This guide will provide information about each protocol in more detail.
The OpenGIS® Web Map Service Interface Standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. The response to the request is one or more geo-registered map images (returned as JPEG, PNG, etc) that can be displayed in a browser application. The interface also supports the ability to specify whether the returned images should be transparent so that layers from multiple servers can be combined or not.
The Web Map Tile Service (WMTS) service conforms to the WMTS Simple profile norm. According to the reference, this service provides a pyramid of tiles in two different projections: WebMercator (EPSG:3857) and Geographic (EPSG:4326), these will be discussed in further detail.
WFS stands for Web Feature Service Interface. This is a standard protocol developed by the OGC for creating, modifying and exchanging vector format geographic information on the Internet using HTTP. The WFS protocol is used to display the One Atlas metadata layer. The user can access useful information about the footprint, date and resolution of the image displayed in the OneAtlas Basemap layer.
The ArcGIS Server REST API provides a simplified way to use services provided by ArcGIS Server. REST enables use of web resources by encapsulating information in the URL and query string of the request. ArcGIS Server includes a REST API for accessing services. The REST API supports most of the functionality available in the ArcGIS Server SOAP API.
The ArcGIS Server SOAP API is an XML-structured language for communicating with ArcGIS Server services based on the SOAP standard. This protocol is to be used with the ESRI suite, particularly with ArcGIS Online.
KML is a file format used to display geographic data in an Earth browser such as Google Earth.
