ISPRS updates Strategic Vision and Mission Plan for its Publications


Publications of the International Society for Photogrammetry and Remote Sensing (ISPRS) are the scientific voice of the Society for the acquisition, processing and analysis of geospatial information addressing technical, commercial, environmental and societal benefits. Our journals are peer-reviewed, indexed and recognized among the top five journals of our field. We promote open access of our publications with a full paper and abstract reviewing, a state-of-art web site and active use of social media for broadest dissemination of information on emerging technologies, innovative methods, landmark research, best practices, and activities of ISPRS Commissions and Working Groups. We envision our publications as the highest quality representations of our society and best means of global communication, recognizing ISPRS as the foremost international scientific society in the fields of photogrammetry, remote sensing and spatial information sciences.


Publications of the International Society for Photogrammetry and Remote Sensing (ISPRS) support its mission to advance geospatial science through international cooperation in research, development and education for the benefit of society and for environmental sustainability. Three aspects of this mission addressing publications are:

  1. to support our peer-reviewed international journals (IJPRS, IOJPRS, IJGI) with excellent editorial resources, expert reviewers and best publishers to ensure highest quality, integrity and cutting-edge content of reported science.
  2. to ensure wide international circulation of the results of research and the records of discussion by publication of the abstract-reviewed ISPRS Archives and the full paper double-blind peer-reviewed ISPRS Annals, which form the record of Congresses, Symposia and other scientific meetings of the Society;
  3. to publish and circulate an e-Bulletin, maintain a web site, and actively pursue other communications such as social media to remain relevant to the interest of the Society and the community at large; and
  4. to publish books of a variety of types including edited collections of high quality scientific papers, authored research monographs, textbooks and tutorials (ISPRS Book Series)

Past and Upcoming Activities of the ISPRS Student Consortium

The Google Earth Engine Singapore (EarthEngine@SG) is a virtual meetup that took place on 13th September 2021, as part of the Singapore Geospatial Festival 2021. Lead by the Nangyang Technological University Singapore – Asian School of the Environment, the ISPRS Student Consortium (ISPRS SC) is one of the organizers of the event, together with National University of Singapore – Centre for Nature-Based Climate Solutions, Imperial College London, Earth Observatory of Singapore and Sabrina Szeto Consulting.

Google Earth Engine (GEE) is a powerful cloud-based platform used to process remotely sensed satellite imagery and conduct large-scale land cover mapping on-the-fly. The applications of GEE are numerous and cover a range of topics such as urban expansion, deforestation, and mapping of hazards, just to name a few. This workshop gathered GEE users from academia, industry, as well as the public sector and non-government organisations for a one-day event comprised of a with a keynote presentation, parallel sessions on the various applications of GEE, a virtual networking session, and workshops offered for beginners to advanced users.

The keynote presentation was delivered by Dr. Nicholas Clinton, Developer Advocate at Google, who gave an overview of the current and future capabilities of the GEE. After a short break, the audience participated in their selected parallel session and specific topic of interest. Keiko Nomura, Director of Product Development at Climate Engine, gave a lecture entitled,  “Fate of forests at your fingertips”. Nicholas Murray, Senior Research Fellow at James Cook University talked about “Losses and gains of Earth’s intertidal ecosystems”. Jakrapong Tawala, Satellite Analyst at the United Nations Satellite Centre, talked about “GEE for the United Nations humanitarian assistance missions”, while Mong Suan Yee, Director of Engineering at Kumi Analytics, provided a lecture on “Machine Learning with Google Earth Engine”.

A virtual networking session followed, which engaged the participants in discussions on the various applications of GEE as well as their visions for its future as one of the many users of this platform. The afternoon was reserved for three different workshops where the audience was guided by the experts in GEE to work on practical. Minerva Singh, Research Fellow at Imperial College London, provided an introduction to GEE for beginners, Keiko Nomura presented tips and tricks for the intermediate audience, while Yvonne Fong, Data Scientist at EO Data Science, provided an intermediate to advanced level overview of the Google Earth Engine Apps.

Overall, the event was a huge success! Thanks to the incredible collaboration among all the organizers, under the leadership of Janice Lee (Nanyang Technological University) – Jose Don De Alban (National University of Singapore), Sabrina Szeto (Sabrina Szeto Consulting), Sheryl Rose Reyes (ISPRS SC) and Minerva Singh (Imperial College London) as well as the amazing technical support provided by the ISPRS SC board members, Charmaine Cruz and Sona Guliyeva, and the Leadership and Service Mentorship Programme mentees, Nicolas Pucino, Laxmi Thapa, Saicharan Vasala and Sunni Kanta Prasad Kushwaha.


The GeoMixer format for connecting and direct networking allows for creating totally new and random connections that you may not have otherwise crossed paths with at a virtual or in-person event. It can be an opportunity for friendly banter, a source of inspiration for future collaborations, a way to connect with a former colleague and share experiences, or a place to share Google Maps or Earth Engine tips or tricks! Who you connect with in your break-out room is up to randomization, which makes this event excitingly unpredictable and unique!

This meet-up was organized with members from Ladies of Landsat, Sisters of SAR, ISPRS SC, Women in Geospatial+, AARS, and SERVIR as one of the virtual meetups in this year’s Geo for Good Summit hosted by Google.


This was a wonderful opportunity to meet members of the remote sensing and geospatial communities who have been using Google Earth Engine in their daily work and research. This meetup was exclusive to all the Geo for Good participants and discussions focused on the applications of Google Earth Engine, with some participants seeking or providing advice to other users. It was also a great time to meet up with folks from North America.


This coming June 6 –11, 2020, the XXIVth ISPRS Congress will be held in Nice, France. After two virtual editions of the ISPRS Congress, the event will be organized again in person and is expected to host thousands of participants including leading specialists and technologists, engineers, researchers and students in the field of photogrammetry, remote sensing, and spatial information sciences coming from universities, research foundations, space agencies, mapping and cadaster agencies, public organizations and private companies, and end-users. The ISPRS Congress will be hosting Youth Forum, which includes technical sessions dedicated for the youth. The Youth Forum will host a series of events led by the ISPRS Student Consortium (ISPRS SC), including a summer school, technical sessions, social events and special sessions.

The technical sessions dedicated for the youth will be organized and papers submitted to the Youth Forum will undergo the regular ISPRS reviewing process. We would like to invite all students, young professionals and researchers to submit your abstracts and full papers to the Youth Forum. Deadline is on January 10, 2022!

A first Geospatial Week in Africa?

Following the postponement of the Geospatial Week (GSW) due to the pandemic in 2021, the Mohamad Bin Rashid Space Center, Dubai, UAE, has informed ISPRS that organising the GSW in 2023 instead of 2021 would unfortunately not be possible (see ISPRS news from June 3, 2021). Nevertheless, ISPRS believes that it is a good idea to have this meeting in the Arab States which is one of the fastest growing areas with a great interest in photogrammetry, remote sensing and spatial information sciences. After several discussions with various parties, the idea emerged to organise the Geospatial Week in Egypt in autumn 2023. Initial feedback has been encouraging, as such arrangement is not only feasible but having a Geospatial Week in Africa for the first time is extremely attractive and welcome.

While under normal circumstances the GSW host is elected at the previous meeting by the working group officers (see Orange Book for details), currently this is impossible as the GSW 2021 had to be cancelled. As a result, Council, while supporting the idea of having GSW 2023 in Egypt, wants to consult with the community to see if additional interests exist. If so, please contact the Secretary General Lena Halounová at before January 31, 2022.

Multiple-Epochs for ISPRS Benchmark on Semantic Segmentation of High-Resolution 3D Points and Meshes now available.

The ISPRS scientific initiative Hessigheim 3D (H3D) on semantic segmentation provides benchmark data in terms of labeled laser scanning point clouds and 3D textured meshes. Our first release earlier this year already provided a UAV data set captured at the village of Hessigheim (Germany). Now additional epochs of that configuration are available. Thus, multi-temporal analyses are feasible.  

The point cloud features a mean point density of about 800 pts/m² and the oblique imagery used for colorization and 3D mesh texturing realizes a ground sampling distance of about 2-3 cm. This enables the identification of fine-grained structures and represents the state of the art in UAV-based mapping.  The respective point clouds are manually labeled into 11 classes and are additionally used to derive labeled textured 3D meshes as an alternative representation.

While our first release provided a data set captured in March 2018, now additional epochs captured with the same high-resolution sensor configuration in November 2018 and March 2019 are available at our benchmark homepage . As fourth epoch, a LiDAR data set captured from a manned aircraft at lower resolution in March 2016 is added, which incorporates typical characteristics of NMA data sets.

Interested researchers can use these state-of-the-art data sets to test their methods and algorithms on semantic segmentation of 3D point clouds and 3D meshes for geospatial applications. Detailed information on the data, the participation and the submission of results for the H3D benchmark is also available in the accompanying paper .
