Eric Theise

Eric Theise is a San Francisco-based artist and geospatial software developer. Through videos and performance he reinvigorates the perceptual inquiries of structural filmmakers, experimental animators, the Light and Space movement, and visual poetry as new possibilities in cartography. His concerns include perceptual pleasure and fatigue, geographies of the natural and built environment, and subverting the presumed objectivity and authority of maps.

Since its Lisbon premiere (2022) he's given thirty-plus performances of "A Synesthete's Atlas"–manipulating projected digital maps in collaboration with improvising musicians–across North America. His animation, "If, as it advanced, the countermap's counter twirled the map around and down, spiraling out from Salesforce Tower to Bolinas as unwaveringly as the boléro. (If Map #5)", appeared atop San Francisco's Salesforce Tower throughout February 2024.

Ilya Zverev

Ilya has been mapping OSM for a very long time. His attention span is very short, hence he also has written a lot of tools, including map editors, organized quite a few mapping parties in various countries, and wrote some wiki pages on surveying. He spend his free time either improving his Every Door app, or wandering in the city collecting hundreds of shops and amenities for the map.

🧠As a trained surveyor, I have honed my skills in data analysis and interpretation, which I have leveraged in my transition towards becoming a Junior Data Scientist. Over the last two years, I have been exploring the realm of GIS, remote sensing, LiDAR, and data processing, which have become my primary areas of interest. My vision of the spatial data industry is that of a puzzle with open datasets, Python, SQL, and Machine Learning techniques being the pieces that need to fit together. In my opinion, the future of GIS lies in Big Data solutions and cloud computing, and I am fortunate to be developing my skills in this direction while working at CloudFerro.

🌎I am familiar with:
👉🏻 Python programming - Numpy, PyQt, ArcPy libraries, GeoPandas, SciPy
👉🏻 PostgreSQL, Postgis
👉🏻 QGIS and ArcGIS
👉🏻Remote Sensing, EO
👉🏻 Extensive processing and interpretation of spatial data

😸Privately I am interested in drawing, cats, dogs and alternative rock.

Mathias Großklaus

Innovation Lead for Participatory Governance @ Agora Digitale Transformation, a German non-profit Think Tank

As an Innovation Lead at Agora Digitale Transformation, Mathias works to ensure that the means of a digitalized world also become effective levers for a just society. Mathias holds a doctorate in political science and has not only led research projects on digital participation and smart cities / regions, but has also implemented numerous innovations into municipal practice. Mathias is convinced that new forms of cooperation between the state, civil society and citizens are needed for a real transformation to succeed.

About Agora Digitale Transformation:
For us, our democracy is the political "operating system" for citizens: How stable it runs depends on how digital technologies are used in the interests of citizens and in exchange with them. We are therefore working on updates for the operating system of democracy - updates that take advantage of the opportunities of the digital transformation as implementable and practice-oriented solutions. For a strong democracy, now and in the future.

Przemysław Boszczar

I am 24 years old. I created my account in 2017, but I have been an active contributor to OpenStreetMap since 2019.
Discovering it pulled me into the world of Geographic Information Systems (GIS) and led me to switch my academic focus to Geography, which I currently study. I also enjoy the analytical aspect of OpenStreetMap and solving problems related to representing the world in the form of maps and databases.
My main passion lies in refining OpenStreetMap data in Poland, particularly in Warsaw and its outskirts. I'm driven by the goal of improving the accuracy and detail of maps in these areas to make comprehensive geographic information accessible to all.
