Tools¶

Add Product¶

Import a satellite product into the EnMAP-Box via the main menu or by drag&drop from your file explorer.

Add Web Map Services (WMS)¶

Add a predefined WMS layer.

Band Statistics¶

The Band Statistics tool reports band histograms and basic statistics like min, max, mean and standard deviation.

Bivariate Color Raster Renderer¶

The Bivariate Color Raster Renderer allows to visualize two bands using a 2d color ramp. Find a mapping example here: https://www.joshuastevens.net/cartography/make-a-bivariate-choropleth-map/

Class Fraction/Probability Renderer and Statistics¶

The Class Fraction/Probability Renderer allows allows to visualize arbitrary many fraction/probability bands at the same time, using the original class colors.

Classification Statistics¶

The Classification Statistics tool reports class histograms and area covered in percentage, pixel and map units.

CMYK Color Raster Renderer¶

The CMYK Color Raster Renderer allows to visualize 4 bands using the CMYK (Cyan, Magenta, Yellow, and Key/Black) color model. Find a mapping example here: https://adventuresinmapping.com/2018/10/31/cmyk-vice/

Color Space Explorer¶

The Color Space Explorer allows a) to select random and predefined RBG band combinations, and b) to animate RGB bands.

Decorrelation Stretch Renderer¶

The Decorrelation Stretch Renderer allows to visualize 3 band. It removes the high correlation commonly found in optical bands to produce a more colorful color composite image.

Enhanced Multiband Color Renderer¶

The Ehanced Multiband Color Renderer allows to visualize arbitrary many bands at the same time using individual color canons for each band (it’s currently more a prototype).

Todo

Find a good dataset and make a video.

HSV Color Raster Renderer¶

The HSV Color Raster Renderer allows to visualize 3 bands using the HSV (Hue, Saturation, Value/Black) color model. Find a mapping example here: https://landmonitoring.earth/portal/ ; select Maps > Global Landcover Dynamics 2016-2020

Todo

Find a good dataset, that is comparable to the Global Landcover Dynamics 2016-2020 from GeoVille, and make a video.

Image Cube¶

The Image Cube tool visualizes a raster image in an interactive 3D view:

Select the raster image.
Specify the:
- Top Plane renderer. It can be any raster renderer known from QIGS, e.g. a Multiband
  
  color renderer that shows the true color bands
- Cube & Slice renderer. This must be a render that uses a single band only, e.g. a Singleband grey or Pseudocolor renderer. It will colorize the band-related pixel values of the 3D image cube and planes relating to the X, Y or Z slice.
Press Load Data to (re)load and render the raster image values.

The 3D scene contains the following elements:

Top Plane - a raster layer for spatial orientation
Image Cube - a volumetric representation of the raster image, showing the raster bands on the z axis
X Slice - a slice along the raster’s X / column / sample dimension
Y Slice - a slice along the raster’s Y / row / line dimension
Z Slice - a slice along the raster’s Z / band dimension
Box (Image) - a 3D bounding box along the maximum image extent
Box (Subset) - a 3D bounding box to show the extent of the spatial subset that migh be used to focus on specific image areas

Metadata Viewer¶

Raster Layer Styling¶

The Raster Layer Styling panel allows to quickly select a RGB, Gray or Pseudocolor visualizations.

It also supports the linking of the style between multiple raster layer.

Raster Source Band Properties Editor¶

The Raster Source Band Properties Editor allows to view and edit band properties of GDAL raster sources, with special support for ENVI metadata.

Reclassify¶

The reclassify tool is a convenient graphical user interface for reclassifying classification rasters.

Specify the file you want to reclassify under Input File. Either use the dropdown menu to select one of the layers which are already loaded or use the button to open the file selection dialog.

Under Output Classification you can specify the classification scheme of the output classification which will be created.

You can import schemes from existing rasters or text files by clicking the button.
Use the button to manually add classes.
To remove entries select the respective rows and click the button.
So save a classification scheme select the desired classes (or use Crtl + A to select all) and click on the button.
Likewise, you can copy and paste classes by selecting them and clicking the ^{Copy Classes} ^{Paste Classes} buttons.

The table is sorted by the Label field in ascending order. The value in Label will become the pixel value of this class and can not be altered.
Double-click into the Name field in order to edit the class name.
Double-click into the Color field to pick a color.

Under Class Mapping you can reassign the old classes (From) to values of the new classification scheme (To)
