Colormaps
Colormaps are templates you can use to add colors to datasets in 3D and Bathymetric charts in 2D.
You can manage colormaps in the Organisation settings under Datasets.
Initially, there are pre-made colormaps ready to use. Start by selecting a colormap which expands to a window containing all the colormap's information. You can change the name, values, and colors according to the dataset.
In the upper-right corner, there is an Add colormap button which opens a new colormap without a name and with default colors.
Write a name for the new colormap and then change and add values and colors. Press the +button on the right side of the color box to add a new colormap value. You can modify the values manually by typing in the numbers, using arrow keys to increase or decrease values, or using the sliders on the color scale. The bottom Sort by elevation button sorts your newly edited values.
Clicking on the color box opens a small pop-up where you can pick any color using different color values or the slider to find a color. The pop-up can be closed by clicking anywhere else on the screen.
You can delete colors and colormap values by pressing the red trash bin button. Be careful when deleting since there is no undo option.
Press the Save button to save the new colormap and return to the list of all colormaps. Note that they are listed alphabetically.
You can also delete Colormaps by selecting a colormap and then pressing the Delete button on the bottom-left side. This action will open a prompt asking for confirmation and informing that deleting is permanent.
In 2D view of the map, in the upper left corner, is the Bathymetric tools menu. Open the menu and select the first tool on the list -**Bathymetric chart**. Colormaps are picked under Options and can be auto-scaled. Auto-scaled colormap means that the values of the colormap are automatically scaled based on the minimum and maximum values of the selected dataset. This tool allows you to apply ready-to-use colormaps with set values on datasets with different value ranges and still get a powerful visualisation.
In the 3D view, clicking Edit allows editing of dataset information. In the lower-left corner of that window, you can find the Set colors to your dataset button that opens the Visualisation settings. Clicking the +button opens a new window with a list of available colormaps. You can edit the available colormaps or create a new colormap right there (listed as Empty). You can change the name, values, or colors. After making changes, values can be re-scaled according to the highest and lowest points of the dataset by clicking the Re-scale values button.
Adding the colormap will automatically add a legend for the colormap on the left side of your map.
When creating colormaps and choosing colors, consider which colors best represent the information shown on the map. Also, consider who will view the data and how they might interpret the map.
