Working with LAS 'services'

Last modified: Mon, 04/03/2017 - 12:50
LAS provides serveral 'back end services' that provide special functionality.
  • Streamable Output
    How to make the bytes of a result (like an image) stream back from LAS directly to the client.
  • The Template Service
    A new service that takes in the UIRequest and puts this request object in the template context. Then the product server forwards the request to the output template. The output template has access to the request obejct along with the information that is already in that context (the LASConfig object and the V7 operations).
  • Using the Java Backend Service (with Google Earth for example) 
    There is a new simple backend service which is just a collection of public Java methods. If an operation is needed that can be easily coded in Java, this is the place to put it. This pages illustartes how this works using the task of making a KML file for Google Earth as an example.
  • The Fregrid Service 
    LAS can be used to transform data on unusual grids to regular lat/lon grids and to deliver the result. This service is implemented on top of Fregrid from GFDL which handles the transformations.
