Metadata for one couple of apikey and data_type

Description

Usage

get_layers_metadata(data_type, apikey = NULL)

Arguments

data_type	Should be "wfs", "wms-r" or "wmts". See details for more information about these Web services formats.
apikey	API key from get_apikeys() or directly from the IGN website

Details

• "wfs" : Web Feature Service designed to return data in vector format (line, point, polygon, ...) ;

• "wms-r" : Web Map Service focuses on raster data ;

• "wmts" : Web Map Tile Service is similar to WMS, but instead of serving maps as single images, WMTS serves maps by dividing the map into a pyramid of tiles at multiple scales.
