numbers, see Fig. 1.7 ). It is possible to pan across the image by dragging the red
box located within the navigation view, which then updates the other windows.

the image displayed. If multiple images (in the same projection) are opened using
otbViewer , it is possible to geographically link the viewers so that panning in one
image updates the zoom extent of the other window.
The Orfeo Toolbox also provides a GUI based application called monteverdi ,
which provides an integrated GUI to display raster images as well as giving access to
GUI based versions of the OTB tools. The latest version, monteverdi 2, is presented
in Fig. 1.8 .
1.6 Structure of the Topic
The way we anticipate you read this topic will depend on your experience and
awareness of the (GDAL) command line tools. If you are a complete novice in the
field of geospatial science and/or open source command line utilities, we suggest
that you begin at the start of the topic and study each of the materials and examples
that are presented. If, on the other hand you are familiar with some or many of the
