- FAQ is a list of Frequently asked questions, with their corresponding answers.
Initial Setup
Geocap comes with a range of settings which can modified to make it easier to work with. One of these settings is the working directory which is the folder Geocap will open every time you browse for something. We will now set this directory and we will also turn on auto save.

Geocap Project
The Atlantis project is built using the UNCLOS project template. This template consists of four main top level folders; Maritime lines, Seabed, Sediment data and Outer limit. The maritime lines folder will hold all the data that has no reference to depth or is located at the sea surface. The Seabed folder will hold all the data located at the seabed, like bathymetric profiles, foot of slope points and so on. The Sediment data folder will hold all the subsurface data like seismic, interpretations, velocities, sediment profiles etc. The Outer limit folder will hold all datasets which is used to construct the outer limit. We are now going to open the Atlantis project and look closer at this project structure.

| Info |
|---|
A Geocap project is stored in a folder on your computer. The project consist of a ".db" file, which contains information about the project tree, and several files which contain the data sets. You should let Geocap manage the files in the project folder and should not store other files in this folder. If you want to make a backup of your projects, or if you want to exchange Geocap projects with other Geocap users you may zip the project folder with all the underlaying datasets into one file. This is convenient for sending e.g. to support@geocap.no. |

Displaying Data
By right clicking a dataset a range of different visualization commands is made available. For each type of dataset Geocap will have a default command. This is the command which will be used when ticking the checkbox next to a dataset. We are now going to display the different datasets in the project using the default command.

Display data- In the folder 2. Seabed / Grids tick the checkbox next to the atlantis seabed surface.
- Right click the atlantis seabed surface and select Zoom to Data. This will make the display window center the graphics window around the dataset.
- In the folder 1. Maritime Lines / Coast lines tick the checkbox next to The Kingdom Of Atlantis coast line.
- In the folder 1. Maritime Lines / Base lines tick the checkbox next to Baseline_Atlantis base line.
- In the folder 1. Maritime Lines / 12 lines tick the checkbox next to Baseline_Atlantis + 12M limit line.
- In the folder 2. Seabed / Bathymetric Profiles / North Sea tick the checkbox next to all the bathymetric profiles

Navigate using the mouse- Zoom in close to one of the bathymetric profiles displayed by press right mouse button and moving the mouse upwards.
- Pan along the seabed surface by pressing the middle mouse button (wheel) and moving the mouse in any direction.
- Zoom out again by press right mouse button and moving the mouse downwards.
- Rotate the displayed data by pressing the left mouse button and moving the mouse.
- Spin the data by holding down Ctrl on your keyboard, pressing the left mouse button and moving the mouse.
- Now try to increase the z-scale by scrolling the mouse wheel upwards.
Move around the 3D model an practice these elements for a few minutes.
| Tip |
