The International Society for Photogrammetry and Remote Sensing (ISPRS) is a non-governmental organization that promotes international cooperation between worldwide organizations with interests in photogrammetry, remote sensing, and spatial information sciences. Established in 1910, ISPRS is the oldest international professional umbrella organization in its field, which may be summarized as addressing “information from imagery”.

ISPRS achieves its aims by:

• Advancing knowledge in the areas of interest of ISPRS by encouraging and facilitating research and development, scientific networking and inter-disciplinary activities;
• Facilitating education and training with particular emphasis in less developed countries; and
• Promoting public recognition of the contributions of the photogrammetry, remote sensing and spatial information sciences for the benefit of humankind and the sustainability of the environment.

The ISPRS scientific and technical programs are organized by five Technical Commissions. These have established about 60 Working Groups which are responsible for particular topics within the Commissions’ areas of interest. Each Technical Commissions holds a Symposium in 2024. Other major events are the ISPRS Geospatial Weeks 2023 and 2025. Smaller workshops will be organized by the Working Groups throughout the four-year period until the XXV ISPRS Congress in Toronto, Canada in 2026.
