Introduction

A workflow in Geocap is a way of combining datasets and actions or visualizations in sequence to produce visualizations, movements and powerpoint style 3D presentations. In this section we will have a look at one of the workflows provided with the Atlantis project and then we will create a workflow our self. It is up to you if you want to create a workflow from the Atlantis project or from the new project you built.

Examine the workflows provided in the Atlantis project.

  1. Make sure the Atlantis project is open.
  2. In Geocap, click File > Open > Workflow, and browse to the Atlantis project folder, then open the the sub-folder called workflows.
  3. Select Basic_Workflow.gwf and click Open. This will open the workflow below the project.
  4. Examine the contents of the workflow items by clicking on the triangles next to the root folders.
  5. Click on the Go to first executable element Image Added icon and then click on the Execute next element Image Added icon. (This will initialize the basic display settings and nothing will appear in the display window yet)
  6. Click on the Execute next element Image Added icon again and notice everything in the Base map folder will be displayed.

  7. Continue clicking on the Execute next element Image Added icon until you reach the end of the workflow and observe how different elements of the Atlantis project are displayed.

  8. Close the workflow by clicking Close

Tip

Note that the user may also execute each element one at a time by right clicking on the command and choosing Execute, see the image below.

 

Workflows are saved as single files on disk with file extension *.gwf, (Geocap Work Flow). It is a good idea to store them in a folder called workflows next to the db folder on disk. In the next exercises we will create a new empty workflow.

We are now going to add different commands to our workflow. There are a number of ways to do this. You can turn on the recorder and start executing commands and they will end up in the workflow or you can copy commands from the Toolbox and paste them into the workflow. You can also add elements from the workflow toolbar.
