Introduction

A geo image is

Pre-post processing of numerical models can take quite some time. Therefore it can be tempting to reduce the time available for proper post-processing. However, properly visualizing your results is of vital important to any analysis. To help your reader to understand the geographical location it can be interesting to plot your results on a georeferenced map with a so-called geo-image. A geo image is being used by other post-processors simply as a background of model results. The standard post-processing tools (e.g. Quickplot, Matlab or Muppet) support images

in “

in “*.jpg” or “*.png” format. With the 'Geo Image' toolbox we can make such a geo-image.

Usage of the toolbox

The 'Geo Image' toolbox allows downloading satellite images and other sorts of maps on a window defined by mouse clicking. These images can be saved in “*.jpg” format. An image can be generate using the following steps:
  1. The image window is defined by clicking on “Draw Outline” in the Working Space and then selecting the window by mouse clicking
    1. Alternatively, the window can be defined by typing the coordinates besides the values “Xmin”, “Xmax”, “Ymin”, “Ymax“
  2. Zoom level defines the resolution of the image with increasing level from 4 to 23. Default the 'auto' option is used. 
  3. Different types of images are available under 'Type' namely
    1. Aerial (satellite) image
    2. Road image
    3. Hybrid: combination between a en and b

 

Figure: With the Geo Image toolbox one can make an image of the area of interest in order the use as a layer for a computational result. In this example, we made a geo image of Barnegat Bay, NJ
