Raster Data Display

This allows for the display of data in a variety of ways common to most image processing packages. The resultant dataset can then be exported as a geotiff for vector interpretation in a GIS package. Each display type is discussed below.

Display Type

This gives options for different types of maps. They are as follows:

Data Bands

The bands to be displayed are chosen here.

Histogram Stretch

The choice of how to map the data is chosen here. The options are:

The user must press to apply button once the setting is changed.

Colour Bar

Here you can choose the colour bar to map the colours with.

Sunshade

This option applies a sunshade algorithm to the data, with the colour overlay being chosen in the Display Type step. Options are:

Save Geotiff

Use this to save your final maps as a Geotiff. This will also save two colour bars (one vertical and one horizontal) or a ternary colour bar. The size of the colour bar relates to how big you wish it to be on the paper map.
