The Hong Kong Planning Department sought to improve urban planning processes by integrating up-to-date satellite imagery into their GIS. Facing challenges of coverage, detail, and quality, they partnered with PlanetObserver, a geospatial data provider. PlanetObserver supplied medium-resolution satellite imagery mosaics covering Southern China, meeting the department's needs. The collaboration revolutionized urban planning accuracy, resource allocation, and project timelines, demonstrating the transformative power of geospatial technologies in shaping sustainable urban development.
