What is WMS?

El servicio de mapas web (WMS ) de ERDDAP le permite solicitar una imagen con datos trazados en un mapa. WMS (external link)

es un Consorcio Geoespacial Abierto (OGC ) (external link)

e ISO (19128) (external link)

estándar para "la creación y visualización de vistas de información registradas y superpuestas en forma de mapas que provienen simultáneamente de múltiples fuentes remotas y heterogéneas". See the list of datasets available via WMS at this ERDDAP installation.

Three Ways to Make Maps with WMS

In theory, anyone can download, install, and use WMS client software.
Some clients are: ArcGIS and uDig. To make a client work, you would install the software on your computer. Then, you would enter the URL of the WMS service into the client. For example, in ArcGIS (not yet fully working because it doesn't handle time!), use
"Arc Catalog : Add Service : Arc Catalog Servers Folder : GIS Servers : Add WMS Server". In ERDDAP, this dataset has its own WMS service, which is located at
https://coastwatch.pfeg.noaa.gov/erddap/es/wms/erdSW1chlamday/request?
(Some WMS client programs don't want the ? at the end of that URL.) See the list of datasets available via WMS at this ERDDAP installation.
In practice, we haven't found any WMS clients that properly handle dimensions other than longitude and latitude (e.g., time), a feature which is specified by the WMS specification and which is utilized by most datasets in ERDDAP's WMS servers. You may find that using hacer un gráfico and selecting the .kml file type (an OGC standard) to load images into Google Earth provides a good (non-WMS) map client. See the list of datasets with Make A Graph at this ERDDAP installation.
Web page authors can embed a WMS client in a web page.
For the map above, ERDDAP is using Leaflet, which is a very versatile WMS client. Leaflet doesn't automatically deal with dimensions other than longitude and latitude (e.g., time), so you will have to write JavaScript (or other scripting code) to do that. (Adventurous JavaScript programmers can look at the Souce Code for this web page.) Another commonly used JavaScript WMS client is OpenLayers.
A person with a browser or a computer program can generate special WMS URLs.
For example,
- To get the Capabilities XML file, use
  https://coastwatch.pfeg.noaa.gov/erddap/es/wms/erdSW1chlamday/request?service=WMS&request=GetCapabilities&version=1.3.0
- To get an image file with a map with an opaque background, use
  https://coastwatch.pfeg.noaa.gov/erddap/es/wms/jplMURSST41/request?service=WMS&version=1.3.0&request=GetMap&bbox=-89.99,-179.99,89.99,180.0&crs=EPSG:4326&width=360&height=180&bgcolor=0x808080&layers=Land,jplMURSST41:analysed_sst,Coastlines,Nations&styles=&format=image/png
- To get an image file with a map with a transparent background, use
  https://coastwatch.pfeg.noaa.gov/erddap/es/wms/jplMURSST41/request?service=WMS&version=1.3.0&request=GetMap&bbox=-89.99,-179.99,89.99,180.0&crs=EPSG:4326&width=360&height=180&bgcolor=0x808080&layers=jplMURSST41:analysed_sst&styles=&format=image/png&transparent=TRUE

For more information about generating WMS URLs, see ERDDAP's WMS Documentation .
In practice, it is easier, more versatile, and more efficient to use this dataset's hacer un gráfico web page than to use WMS for this purpose. See the list of datasets with Make A Graph at this ERDDAP installation.
