How to Find the Services
The Hub Data Portal is the way to search for or browse for web services - both Esri format and OGC format. Important information on the Hub Data Portal can be found here.
Searching for web services can be simply done by entering in a search word such as "roads" or "wfs". Browsing for web services is best done by clicking on the Web Services link on the left.
If you are interested in a certain data type then search for that data type, e.g., "roads". If you are interested in a certain type of web service then search for that web service type, e.g., "wfs".
The results from searching for or browsing for web services will display data titles with each title having an associated 'More Information' button. Click on this to view the metadata. While viewing the metadata scroll down to the 'Transfer Options' section. Depending on the item, you may see one or more data download links and you may see one or more links to the web services.
Depending on the data, links to the web services contain the following:
| Web Service Link Text Contains | Comment |

| Click to view WMS capabilities | Displays the capabilities of the service; contents can be used by web application developers and by desktop GIS users. E.g., use the URL following xlink:href to access the particular service |
| Click to view WCS capabilities | Displays the capabilities of the service; contents can be used by web application developers and by desktop GIS users. E.g., use the URL following xlink:href to access the particular service |
| Click to view WFS capabilities | Displays the capabilities of the service; contents can be used by web application developers and by desktop GIS users. E.g., use the URL following xlink:href to access the particular service |
| Esri REST including WMS | Displays the contents of the Esri rest interface which includes the ability to preview the data using the ArcGIS JavaScript link, view the data in ArcMap, view the layers and projection of the service, and includes the link to the WMS capabilities. |

| Copy this WMS URL link into your application | For convenience, this is generally the same xlink:href URL as what is found in the capabilities file |
| Copy this WCS URL link into your application | For convenience, this is generally the same xlink:href URL as what is found in the capabilities file |
| Copy this WFS URL link into your application | For convenience, this is generally the same xlink:href URL as what is found in the capabilities file |
| Click to generate KML | This allows one to select which layer(s) should be used to create a KML data stream for use with Google Earth. It is generally preferable to use the ‘Vector layers as vectors and raster layers as images’ option. |
