Features

GUI

The EnMAP-Box offers a powerful graphical user interface (GUI) for an integrated visualization of raster, vector and spectral library data. Move the mouse over the GUI sections for further information.

Visualization

Like QGIS, just more maps

visualize raster and vector data interactively and in multiple maps, e.g. to compare different band combinations or satellite observations.
each map has it’s individual and fully customizable layer-tree
free arrangement of maps, e.g. side-by-side, horizontally, vertically or in nested-layouts
maps can be linked spatially, e.g. to always have the same map scale, show the same map-center, or both
raster layers can be linked spectrally to always show band combinations with similar wavelengths

Explore your raster data interactively

The EnMAP-Box provides new raster renderers that enhance the visualization of imaging spectroscopy data and other raster outputs, e.g.:

Renderer	Example
Bivariate Color Renderer Visualize two bands using a 2d color ramp.
Class-fraction or probability rendering Visualizes multiple class factions/probabilities at the same time using the original class colors.
HSV color rendering Visualizes 3 bands using the HSV (Hue, Saturation, Value/Black) color model
CMYK Color Raster Renderer Visualizes 4 bands using the CMYK (Cyan, Magenta, Yellow, and Key/Black) color model
Decorelation Stretch Renderer Removing the high correlation between 3 band for a more colorful color composite image.

Spectral Libraries

Your measurements, your data.

The EnMAP box offers a wide range of options for creating spectral libraries and to describe and visualize their spectral profiles.

Read spectral profiles measured with ASD, SVC (*.sig) or Spectral Evolution (*.sed) field spectrometers
Create profiles from raster images, e.g. for given vector locations (point or polygons)
Save spectral profiles in vector datasets and show their coordinates, e.g. using GeoPackage, GeoJSON or DBMS like PostgreSQL or HANA DB
Keep profiles together that belong together, e.g. reference and target radiances and reflectance derived from
Annotate your profiles as needed, e.g. using text (String, Varchar), numeric (int, float) or binary (BLOB) datatypes
Query your profiles using powerful SQL expressions
Plot profiles from different instruments simultaneously against wavelength units, e.g. nanometers, micrometers

Algorithms

The EnMAP-Box adds more that 190 processing algorithms to the QGIS Processing Framework. Start them from the QGIS/EnMAP-Box GUI, from python, command line interfaces, or connect them with algorithms from other plugins in the QGIS Model Builder.

<show python example>

Open the OSGeo4W or conda shell and call:

qgis_process run enmapbox:PredictClassificationLayer ^
      --raster="%data_dir%\enmap_potsdam.tif" ^
      --classifier="%output_dir%\rfc_fit.pkl" ^
      --matchByName=1 ^
      --outputClassification="%output_dir%\classification.tif"

qgis_process run enmapbox:PredictClassificationLayer \
      --raster="$data_dir/enmap_potsdam.tif" \
      --classifier="$output_dir/rfc_fit.pkl" \
      --matchByName=1 \
