Introduction

Geocap is a software for mapping and modeling geoscientific data, designed with focus on interactivity and flexible control of visualization and manipulation. Geocap is operated through projects. The project "holds" the data in a folder-like structure, similar to Windows "File Explorer". All datasets are "children" of either a folder or another dataset. Geocap offers different project templates, giving you a pre-defined folder structure that fits your workflow for a specific type of work. In this tutorial collection we are going to use the Shelf/UNCLOS project template.

This section will guide you through the basics of opening a project, explore and display the project data and navigate in the graphics window.

Explore the project folder structure

  1. Expand the folders and observe the sub folders
  2. Look at the right-click menus.
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.

Display data

Display the various datasets in the project

  1. Locate a grid dataset (structured points or seabed) e.g. 2. Seabed/Grids/atlantis
  2. Tick the checkbox next to the dataset to display it.
  3. Right click the dataset again and select Zoom to Data. This will make the display window center the graphics window around the dataset.
  4. Display some of the lines e.g. lines found under 1. Maritime Lines.
Info

Note that by checking and unchecking the first level folder 1. Maritime Lines, or 2. Seabed all datasets displayed under this folder are shown and hidden.

Navigating in the 3D window

Info

Note: Operating Geocap with a two-button mouse or using the Touch-pad is possible but not recommended. The recommendation is a three-button mouse with a wheel, see picture below.

Navigate using the mouse

  1. Try to zoom in and out.
  2. Try to pan.
  3. Try to rotate the data.
  4. Try to scroll the wheel to increase the z-scale.
  5. Now try to examine three areas more closely my panning, zooming in closely and rotating.
