2.3.3 Visualize an image with Monteverdi

This module allows to visualize raster or vector data. It allows to create RGB composition from the input rasters. It is also possible to add vector dataset which are automatically reprojected in the same projection of the input image or Digital Elevation informations.

The viewer offers three types of data visualisation:

The Visualization offers others great functionnalities which are available in the detached window. It is for example possible to superpose vector dataset to the input image (see figure  2.4).

The ”Setup Tab” allows to modify the RGB composition or use the grayscale mode to display only one layer.

The ”Histogram Tab” get access to the dynamic of the displayed layers. The basic idea is to convert the output of the pixel representation to a RGB pixel for rendering on conventional displays. Values are constrained to 0-255 with a transfer function and a clamping operation. By default, the dynamic of each layer is modified by clamping the histogram at min+2% and max2%.

There is also possible to select pixel coordinates and get access to all the informations available in the “Pixel description Box”.
