Building vectorization, specifically through the detection of rooftops in high-resolution (HR) and very high-resolution (VHR) satellite images, is a key process in various fields, both civil and military. This approach allows for precise identification of building footprints using images with resolutions as fine as 1.5 meters per pixel.<\/p>

The use case implements a Deep Learning algorithms<\/strong> for the automated detection of rooftops<\/strong> in satellite images, facilitating accurate building vectorization. This process is essential in sectors such as:<\/p>

  • Military domain:<\/strong>Enhances geospatial intelligence and strategic planning, enabling more precise and efficient decision-making.<\/li>
  • Urban planning:<\/strong>Useful for updating and maintaining geospatial databases of cities.<\/li>
  • Disaster management:<\/strong>Helps identify damaged buildings after natural disasters to optimize response and reconstruction efforts.<\/li><\/ul>

    The model, integrated into the SEDA geospatial intelligence platform<\/strong>is based on a CNN U-Net architecture to segment rooftops. This improves accuracy and efficiency, reducing the required human intervention and speeding up the geospatial analysis process.<\/p>

    The vectorization process generates the following output reports:<\/p>

    • Vector maps:<\/strong>Polygons representing the detected rooftop footprints.<\/li>
    • Geospatial visualization:<\/strong>Maps showing the location and shape of detected buildings overlaid on satellite images.<\/li><\/ul>

      These results can be exported in standard geospatial formats (such as GeoJSON or Shapefile) for integration into other geographic information systems (GIS). GeoJSON<\/strong> o Shapefile<\/strong>for integration into other geographic information systems (GIS).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

      • Military intelligence:<\/strong>Allows for the detection, mapping, and analysis of structures of interest in strategic areas to improve planning and surveillance.<\/li>
      • Cartography and urban planning:<\/strong>Automatically updates maps of cities and rural areas, providing more accurate information for infrastructure management.<\/li>
      • Disaster management:<\/strong>Useful for identifying buildings affected by natural disasters like earthquakes or hurricanes, enabling a faster response.<\/li>
      • Sustainability and environmental analysis:<\/strong>Allows for the assessment of urban growth and its impact on the environment by comparing construction areas over time.<\/li><\/ul>

        The automatic vectorization of buildings<\/strong> through HR and VHR satellite images is a powerful and versatile tool that can be applied in multiple sectors. The use of Deep Learning algorithms<\/strong> not only improves detection accuracy but also optimizes the resources needed for geospatial analysis. This approach offers a robust solution to meet needs in both military and urban management and emergency response.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
