Open data available via web services.
Supported services are:
Service | Description |
Enhanced Compression Wavelet | Using the Enhanced Compression Wavelet (ECW) protocol allows you to view ECW and JPG2000 raster images available from a server. |
Onboard Service | The CARIS Onboard™ service allows you to view a product, such as a mosaic or gridded surface, as it is updated in real time during data processing. See Onboard Service for more information. |
Tile Map Service | A Tile Map Service (TMS) returns raster images from a tile-based portrayal service for geospatial data. TMS is similar to a WMTS, but with different standard protocols. The default tile size is 256 x 256 pixels. A well-known provider of a TMS is OpenStreetMap but users should be aware of their Tile Usage Policy before using this service. Information can be found at: http://wiki.openstreetmap.org/wiki/Tile_usage_policy |
Web Coverage Service | A Web Coverage Service (WCS) opens coverages from a server. A WCS is an Open Web Service (OWS), and coverages are geospatial representations of map data retrieved as rasters. These rasters may be images or they may contain depth information. See OGC Web Services for more information. |
Web Map Tile Service | A Web Map Tile Service (WMTS) returns raster images. A WMTS is a tile-based portrayal service for geospatial data. Tiles are retrieved at a resolution based on the current view scale in Teledyne CARIS applications, similar to CSAR data. Tiles will be retrieved in their entirety, regardless of the current view extents. See OGC Web Services for more information. |
If you use a proxy server to access your network or browser, you may need to define connection settings. See Options and contact your system administrator for assistance.
Some services provide different sources in different versions, but not all versions are supported in Teledyne CARIS applications. The following service versions are supported:
• WMTS 1.0.0
• WCS 1.0.0, 1.1.0, 1.1.1
Contact Teledyne CARIS Customer Service if you have issues with the version used by the server that you are accessing.
WMTS and WCS data opens in the first coordinate reference system that is supported in Teledyne CARIS applications. TMS is always opened in EPSG:3857 (Google Mercator). The coordinate reference system of each source is used, and they are re-projected on the fly.
Some sources are opened as raster images. The format of the image is the first available format that is supported in Teledyne CARIS applications. Certain services attempt to use specific formats. For example, WCS will attempt to retrieve a GeoTIFF if GeoTIFFs are available from the server. If this format is not available, it will look for PNG, then others.
Sources
For the WMTS, WCS and Onboard service types, you are prompted to select the sources you want to open if more than one data source is available for the URL specified. Each source from a service can have unique data extents.
• If data was open before connecting to the service, the service will display only data within the extents of the current view.
• If no data was open, the selected source will be displayed using the full extents available for that source. For a TMS service, this means the full world map.
For the other service types, data will be returned for the view extents specific to the URL entered.
If you experience problems displaying data from a service, you may need to select an appropriate coordinate reference system for the service layer. See Coordinate Reference System Selection for more information. |
All data provided for a service can be accessed by changing the view using the Zoom, Pan and Overview commands. The data is updated dynamically any time the view is changed or refreshed.

Interface
The following dialog box is used for each of the web services, with a dialog box title relevant to the type of service selected.
Option | Description |
URL | The address of the service to which you want to connect. Each time an address is entered and run, it will be saved in the list for future use. Each service can remember up to 10 addresses. To remove a saved address, right-click the address in the list and choose Delete. |
A secondary dialog box is used by the web service commands when multiple data sources are available for a specified service.
Option | Description |
search | FIlter the list of available sources using a search term or phrase. Only sources that contain the search phrase will be displayed in the list. 1. Type a search phrase in the box. The list will automatically begin to filter as you type. |
Available Sources | A list of all available sources. 1. Click to populate the check box for each data source that you want opened and displayed. |
Procedure
1. Select the command for the desired service.
2. Either:
• type a valid address, or
• select a previously used address from the list.
3. Click OK.
If only one source is available, the connection is made. If multiple sources are available, the Select Sources dialog box is displayed.
4. Choose one or more sources.
5. Click OK.
The selected data is opened and added to the Layers window. If you selected multiple sources, a layer group is added to the Layers window containing a child layer for each data source that was selected from the service. The layer group is named according to the service to which you connected.
