This means that users can extract information like roads, buildings, and vegetation from aerial or satellite imagery.
4. ArcGIS Pro
The bulk of remote sensing tools in ArcGIS Pro can be found in the Image Analysis extension. This extension provides access to a set of tools for analyzing imagery and performing advanced image analysis tasks.
For instance, it enables users to create and modify raster datasets, visualize and explore imagery. You can also execute more sophisticated analyses including terrain analysis, image classification, and spectral analysis.
With the Image Analysis extension, you can quickly process large amounts of imagery and extract valuable information from it. You can also use its imagery workflows to perform a set of tasks such as time-series analysis and change detection with deep learning.
5. QGIS 3
QGIS 3 is loaded with remote sensing tools by default like its raster analysis, terrain analysis, and interpretation toolboxes. But QGIS 3 isn’t limited to just its own toolboxes, you can leverage a wealth of capabilities using toolboxes from SAGA GIS, GDAL, and GRASS GIS.
If you’ve ever used QGIS before, you’ll know that you can extend its capabilities by using plugins. One of its most popular remote sensing plugins is the free open source Semi-Automatic Classification Plugin (SCP) plugin.
The SCP plugin provides many features and functions such as allowing users to quickly and easily download and classify satellite imagery. There are also algorithms for pre-processing, post-classification improvement, accuracy assessment, and much more.

6. Trimble eCognition
Trimble eCognition is a specialist in feature extraction through the means of object-based image analysis (OBIA). If you’ve ever used eCognition, you’ll know it uses pattern-recognition algorithms to divide imagery into meaningful objects (not just pixels).
After executing a multi-resolution segmentation algorithm, each object has statistics associated with them. By using spectral and spatial characteristics, you can create the most advanced land cover classification today. Further to this, you can build rulesets to automate land cover creation and apply them to various types of imagery.
Trimble eCognition accepts a variety of inputs such as LiDAR point clouds, aerial, satellite, and UAV imagery. Although it highly succeeds in land cover development, it’s not a complete remote sensing suite. Because it lacks common tools such as georeferencing, 3D visualization, or SAR capabilities, it doesn’t get a homerun rating from us.

8. SAGA GIS
Admittedly, SAGA GIS is a bit rough around the edges. It’s an older remote sensing software so it’s definitely not as polished as the others on this list. But with that said, there’s still a lot you can salvage from it.
SAGA GIS has a wide range of features that allow users to perform basic data processing and analysis tasks related to remote sensing. For example, you can use it to mosaic, clip, and split imagery, as well as transform image projections.

For open source remote sensing software, you get a ton of tools. Honestly, some tools we’ve never heard of. But the more you explore them, you’ll learn that some may not be reliable and 100% functional. But it’s still worth the time and effort to check it out for its rare remote sensing tools. And don’t forget that you can leverage the SAGA GIS toolbox in QGIS 3 too.
