Enabling Global Land Tenure Security Using High-resolution Imagery

摘要

DigitalGlobe, a commercial leader in the satellite remote sensing industry, has been capturing images at 50cm resolution for the last decade. The latest generation of its Worldview systems are now collecting imagery at 30cm (lft) spatial resolution. Furthermore, the company has now invested in developing accurate and high-quality mosaics of nations that can become the foundation for developing the global cadastre or land administration system (see Figure 1). In countries such as the USA, it is already an acceptable practice to use imagery as a reference for creating urban parcels.
