Help Resources

The Help Resources include basic and statistics tutorials, function documentation, and other resources to help you get the maximum utility out of the Streaming Data Library (SDL)

When you have created your own added value product using our analytics platform you can easily consume it through either our API or as Linked Data.

Consuming your data through the VISual Maps-API

When you have finished creating your added value product (learn how in our tutorials), on the dataset page you will find various options to consume your data on the ‘Data Files’ tab. At the top of the page you will find two buttons ‘Get OPeNDAP URL’ and ‘Create SPARQL Endpoint’. To consume your data through the API select the first button and copy the OPeNDAP URL that is presented on the screen.

   

In our API documentation for Android and iOS in the code examples, you will find that you can use a LayerID to specify the layer you want to use. This LayerID can also be the OPeNDAP URL you just created. In order to use the API to load your own specific subset or value-added product, see the Android example below:

 

Consuming your data as Linked Data

If you have found the data you want and created your needed subset or added-value product, next to consuming it through our API, it is also possible to access the data as Linked Data in order to easily combine it with other datasets. Similar to consuming the data through our API, on the dataset page head to ‘Data Files’ tab and click the Create SPARQL Endpoint button. As this method is mostly suited for consumption of specific subsets (both in time and space) when clicking this button you might get a warning stating that the selected subset is either too large, or that there is no data available for the selected period. If you subset is suited to consumption as Linked Data you will be presented with the following screen:

 

The ‘Token’ value, for now, should be ‘ramani’. The SPARQL Endpoint Name can be user selected, however make sure there are no spaces in there, and only letters and numbers. Otherwise the endpoint creation will fail. The title can be selected by you, and will show up in our system under this name. Make sure to remember this name so we are able to find it in case we need to offer support. The final step is the hardest and requires some special attention. You will need to enter the parameters for the endpoint. The default values are VAR for the variable, T for the time parameter, and X and Y for Latitude and Longitude. In order to find the VAR for your specific datasets take a look at the URL.

 

For example, the Leaf Area Index dataset has the following URL: http://analytics.ramani.ujuizi.com/SOURCES/.Copernicus/.Land/.LAI/.LAI.   The part behind the final / in the URL is the VAR you will need. So in this case the VAR should be replaced by LAI. For the T, X and Y, please go to the ‘Data Selection’ tab. Here you will find the variable names for this specific dataset in the Restrict Ranges section.

 

In this case these are time, lat and lon. This means the SPARQL Endpoint setup screen should be filled as follows:

 

After clicking Create Endpoint URL you will be presented with the following screen where you can copy the endpoint URL to use to consume your data.
