Quel logiciel de télédétection offre les capacités d’extraction de caractéristiques les plus avancées ?

Referring to over 10 years of my experiences, the most powerful image processing software is ENVI. It is owned by NV5 Geospatial (USA)that provides all preprocessing, processing, and post processing tools through a wide range of options in a very friendly platform. It got a powerful and reliable service in its “help”. ENVI supports both pixel and object based classification. Most of the time I have exported the results through ENVI then to have my last change in data base, layout,map, used ArcGIS and to have details of categorizing in the classification spatially in object based methods (OBIA) used eCognition software. anyway ENVI has always been the main and parent software for image processing, from my point of view.

Look for software with algorithms for pattern recognition and machine learning. Consider tools for object-based image analysis (OBIA) for precise feature extraction. Customizable tools offer flexibility to tailor to specific project needs. Software should support both pixel and object-based classification methods. Reliable software should provide powerful preprocessing and post-processing tools.

Although there are a number of tools and software available for remote sensing and GIS analysis but ENVI is one of the best among all for the remote sensing analysis

In my older experience undoubted very popular has been ArcGIS versions from Dangermond's ESRI in Southern California. Others were NASA Classification software. Two leaders in development Willow Run Lab Ypsilanti U of Mi with multivariate analysis including radiative transfer atmospheric corrections, ML based on training set approach and formed basis for 1972 ERTS 1 and 2 or now called LANDSAT 1. 2 satellites on which I worked. Competing software Purdue Univ Clustering algorithms, and this was the approach also used by then USSR Hydrometeorological services. I used many of these as I established the Remote Sensing Agency in India in 1975. Dr Ravi Sharma NASA Apollo Achievement Award Former Scientific Secretary ISRO HQ

Orfeo Toolbox (OTB) excels in advanced feature extraction from remote sensing imagery. Integrated with QGIS, OTB provides a vast array of algorithms for image segmentation, classification, and object-based analysis. Its machine learning capabilities enable accurate identification and extraction of complex features like land cover types and infrastructure. Additionally, RSGISLib offers advanced feature extraction tools for remote sensing data analysis within a Python environment, enhancing flexibility and automation in processing workflows.

Ensure the software offers robust image processing capabilities. Look for features like radiometric correction and spectral analysis. Effective noise reduction algorithms are essential for accurate feature extraction. Spectral analysis helps distinguish between different materials and land cover types. Comprehensive image processing functions are crucial for preparing data.

Integration capabilities allow for seamless data transfer between different GIS software and data formats, enabling comprehensive analysis. The software should support a wide range of geospatial data formats, including common ones like GeoTIFF and shapefiles, as well as specialized formats for remote sensing data. Integration with popular GIS platforms like ArcGIS and QGIS facilitates data exchange and leverages the strengths of each tool. Efficient data transfer methods and support for open geospatial standards ensure compatibility and enable collaborative workflows. Access to geoprocessing tools from other GIS software enhances analysis capabilities.

Advanced remote sensing software typically provides extensive user support to assist with feature extraction. This includes detailed documentation, tutorials, and active user communities. Documentation offers comprehensive information about the software's features and workflows. Tutorials and training materials help users understand and master feature extraction techniques. User communities and forums enable interaction, knowledge sharing, and troubleshooting. Technical support channels are available for resolving complex issues. Access to these resources is invaluable for effectively utilizing advanced capabilities and overcoming challenges. When evaluating software, considering the quality of user support is crucial for feature extraction

1) Share insights, examples, or stories that didn't fit into the previous sections. 2) Consider factors like cost, scalability, and compatibility with existing systems. 3) Evaluate user feedback and reviews to gauge software performance and reliability. 4) Look for software that aligns with long-term project goals and objectives. 5) Explore trial versions or demos to test software features and functionalities.
