Mapsurvey for researchers

Run participatory-mapping (PPGIS) and citizen-science studies without enterprise costs. Participants pin locations, draw routes, and outline areas alongside structured questions; you get clean GeoJSON + CSV for QGIS, R, or Python. It's open source, so your instrument and pipeline are transparent and reproducible — and free, so a grant isn't a prerequisite.

Open source (AGPLv3) GeoJSON / CSV → QGIS, R Free, no grant needed EU-hosted / self-host

Why researchers use it

Rigorous spatial data collection, openly

Transparent & reproducible

Open-source code (AGPLv3) means the instrument and processing are auditable — good for methods sections, ethics review, and replication.

Analysis-ready output

Points, lines, and polygons export as GeoJSON + CSV — straight into QGIS, R (sf), or Python (geopandas), no conversion.

No budget barrier

Free to use and self-hostable — a fit for student projects, unfunded pilots, and NGOs in the Global South priced out of commercial PPGIS.

Data sovereignty

Host it yourself with Docker, or use the EU-hosted version — keep sensitive fieldwork data where your IRB/DPA requires.

FAQ

Frequently asked questions

Is Mapsurvey suitable for PPGIS and participatory research?
Yes — it is built for public-participation GIS: point, line, and polygon input captured against your own questions, exported as analysis-ready GeoJSON/CSV.
How do I get the raw spatial data for analysis?
Every response — including map geometry — exports as GeoJSON plus a CSV for non-spatial answers, so results drop straight into QGIS, ArcGIS, or a spreadsheet. You own the data.
Do participants need an account?
No. Respondents open a public link and answer on the map — no sign-up or login required. Only survey creators need an account.
Can I self-host for ethics/data-governance requirements?
Yes. Mapsurvey ships as a Docker stack you can run on your own infrastructure, so response data stays on servers you control — useful for GDPR and data-residency requirements.
Is it really free to start?
Yes. Mapsurvey is open source (AGPLv3) and free to start — you can create and publish a map-based survey without paying, and self-host the whole platform at no licence cost.
