h2. 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. The Atlantis Project is used throughout this tutorial.

h4. Examine the workflows provided in the Atlantis project.

# In Geocap, click *File > Open > File*, and browse to the Atlantis folder, then open the the sub-folder called *workflow*.
# Double click on the file called *Atlantis Basic Workflow.gwf* to open it, or single click to highlight it and then click, *Open*. This will open the workflow below the project.

# Examine the contents of the workflow items by clicking on the triangles next to the root folders.
# Click on the *Go to first executable element* !att:_img_icon^resultset_first.png! icon and then click on the *Execute next element* !att:_img_icon^resultset_next.png! icon. (This will initialize the basic display settings and nothing will appear in the display window yet)
# Click on the *Execute next element* !att:_img_icon^resultset_next.png! icon again and notice everything in the *Base map* folder will be displayed along with a short *flight tour* (animation).
# Continue clicking on the *Execute next element* !att:_img_icon^resultset_next.png! icon until you reach the end of the workflow and observe how different elements of the Atlantis project are displayed.

Following the steps above, open and examine the other workflows in the *workflows* folder.

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.

h4. Create a new workflow

In this exercise we will create a workflow that displays seabed and land and some important lines from the project.
* Click *File > New > Workflow*. Then a browser pops up.

The workflow is saved as a single file on disk with file extension **.gwf*, (Geocap Work Flow). A good idea may be to create a folder in your project called *Workflows* and put the workflow there.

# Press the *New Element* icon to create the first entry. That may also be achieved by a right-click *New Element*.
# Select the *Display* !att:_img_icon^pencil.png! command found in the *Commands* folder and click *OK*.
# Right-click the *Display* !att:_img_icon^pencil.png! command in the workflow and select *Edit*. Then this panel pops up:

In a workflow, you will need to browse in an object from the project. The command usually requires a dataset to do an action on (such as a type of display).

# Browse to the coastline folder under *1. Maritime lines*, highlight *The Kingdom of Atlantis* and click *OK*.
# Choose the display settings you like (color, glue to surface or not, etc.) and click *OK* again.
# Right click the element in the workflow and choose *Execute*. Alternatively, click the *Execute* icon.
# Examine how your display looks and edit the command if necessary to achieve the results you want by right clicking on the command and choosing *edit*.
# In order to keep your workflow organized it is recommended to change the name of the newly added commands from *Display* to something more descriptive like, *Display Coastline Yellow* which is done by right clicking the command and choosing *Rename*.

Note that commands may be copied from *Shared commands*, *Item commands* and *Schema commands* and pasted into the workflow.
# Right click the *Map sea* command in the *Toolbox* and select *Copy* !att:_img_icon^copy.png!. (It should be located under *Schema Commands* if you have selected a *Seabed Surface*.)
# Click the *Paste* !att:_img_icon^paste.png! button in the workflow.
# Again you must edit it and browse your seabed surface into the panel.
# Remember to save the workflow by clicking !att:_img_icon^save.png!
