How To Use TerrAvion's Adjustable Thermal Color-map
The TerrAvion Dynamic Color-map allows users to focus their thermal images to bring out more detail and variability. While the thermal data remains constant for any particular image, altering the thermal color-map for that image can change the way that data is illustrated in the image you see. Follow the directions below to learn how to manually adjust your thermal color-map.
Adjust Your Thermal Color-map
Note: As you alter your thermal color-maps, please keep in mind that the thermal data will remain constant. You are not altering the temperature, only the way the temperature is illustrated in your imagery.
2. Select a field and turn on the Thermal Layer. (Navigating the TerrAvion OverView Interface)
3. When you select the Thermal layer, you will now see a thermal image with an adjusted color-map
4. You can also manually adjust your color-map. To do so, first select the Thermal layer and click
the Histogram button at the top of your screen to the right.
5. When you open the histogram window, click the toggle where it says Auto to switch to the Manual
6. After you turn on the Manual adjustment mode, note the range of temperature values displayed
on the x axis of the histogram.
7. Move the two adjustment points to either end of the range you noted in the previous step.
8. Note the color changes on the thermal histogram. The goal is to see more color representation on
the histogram. If you do not see noticeable color variation on the histogram, readjust it.
9. Click Update Color Map
10. If your map isn’t displaying the detail and variation in the way you wish to see it, readjust the
scale, or click the Fit Histogram button to automatically fit your color-map.
