1. The following section highlights what are the steps required for performing a valid Grid processing using the features provided by the GreenLand application This use case contains an already defined project called Istanbul project_imported In this case the project contains two workflows NDVI and EVI Step 1 Sign in your account Usemame Password Sign in New account Figure 1 Sign in GreenLand application Step 2 Open the project content The process step was already completed for this project using the Grid infrastructure Click the project name to open its content Figure 2 It is important to mention that you could not execute a project that has the Executing project status This status is displayed just under the project name in the projects list New project Edit project Delete project E Al Add wor a a Istanbul project importec Al f Created at Oct 10 2011 Status Execution completed Figure 2 Identify the project and open its content Step 3 Output results management In order to handle the output results just select the project from the project list and use the Execution results option Figure 3 Start process Project information Name NDVI_Imported_Author Created at Oct 12 2011 Status Execution completed Use the Execution results option to manage the results Statistics 1 Workflows and 0 instances Description Testi L Execution results G Ba a Figure 3 Vis2. 36 0 Completed eb ddd1d 69d8 4a074 Figure 15 Output result management It is worth to mention that the execution process may take some time depending on the workflows complexity A refresh timer located above the monitoring table will update the execution data based on a 10 85 or 100 seconds time interval Figure 15 4 Conclusions This is the first version of the GreenLand application and there are some things to be improved or added as new functionalities e Extend the GreenLand database with new workflows e Allow the user the possibility to create its own workflows using a WorkflowEditor module e Implement the online result analysis module e Implement the uploading data e g satellite images functionality e Support for the OGG services

GreenLand v2 application user manual 1 Menu option features This section contains the short description of the menu bar options provided by the GreenLand application New project it allows the creation of a new project A project is one of the key concepts of the GreenLand application that stores one or more workflows Edit project useful for changing the name or the description of an already existing project Delete project allows the user to delete an existing project This action is triggered together with a warning popup message just to clearly notify the user regarding this aspect All it could be used to check uncheck all the expandable workflow together with their child items in the workflows list Add workflows opens a table populated with existing workflows inside the GreenLand database Using this feature the user is able to attach a list of workflows to the current selected project Remove workflows in order to remove a workflow the user has to select it first The selection is made by checking the combo box module positioned on the left side of the workflow s name Start process by using this option the user triggers the Grid execution related to the current selected project Several pre processing validations are performed such as o Check if the project contains at least one workflow o Check if all the workflows inputs are properly specified O etc 2 Use case scenario 1 Use an already existing project
