Capabilities

Everything you need for spatial surveys

Interactive map surveys

Respondents mark places, draw routes, and outline areas directly on the map. Mobile-friendly with crosshair mode for precise input.

13 question types

Text, number, choice, rating, date, image — plus three cartographic types. Sub-questions that appear based on answers. Visual drag-and-drop editor.

AБ

Multilingual surveys

One survey, multiple languages. Questions, choices, and the thank-you page all support translation. Respondents pick their language on entry.

Data export

Download responses with geodata in a single ZIP. GeoJSON + CSV, ready for QGIS, Excel, Python, or R. Import and export survey structures for reuse.

Deploy in minutes

Three commands in the terminal and the platform runs on your server. Or just sign up on mapsurvey.org — nothing to install.

Open source

Full source code on GitHub. Adapt, extend, contribute. AGPLv3 license guarantees the code stays open forever.

Create Your Own Mapsurvey

Who it's for

Built for people who shape places

Urban Planning

Ask residents where they need bike lanes, where crossings feel dangerous, where parks are missing. People draw routes and outline neighborhoods — not just drop pins.

Academic Research

Run spatial studies without paying for expensive platforms. Download results, analyze in your tools, publish. Cite the open-source tool in your papers.

Civic Tech & NGOs

Deploy on your own server for participatory budgeting, public space assessments, or transit route planning. Full control, zero vendor lock-in.

Municipalities

Citizen data never leaves your infrastructure. No vendor lock-in. No annual subscription. Compliant with data sovereignty requirements.
