GOAT: the open-source WebGIS, now with AI
Ask a planning question and GOAT AI builds the analysis, ready for you to adjust. Or do it yourself: analyze data, compute accessibility indicators, build dashboards and work together, all in your browser.
WebGIS with AI
What is GOAT?
GOAT is a German open-source WebGIS platform for spatial analysis, accessibility modeling, and geospatial data visualization.
It enables planners, researchers, mobility experts, and public sector organizations to analyze spatial data, create dashboards, automate workflows, and collaborate on maps directly in the browser. With GOAT AI, you can also start from a planning question: it finds the data, builds the workflow and makes the map, and you check every step.

Start from a Planning Question
Type your question in plain language. GOAT AI finds the data, runs the indicators, builds the workflow and makes the map. Every step is a normal GOAT step you can open, check and change.
Ask in Plain Language
No GIS terms needed. Describe what you want to know, the way you'd ask a colleague.
See How It Was Built
GOAT AI builds a normal GOAT workflow. Open any step, adjust the parameters and run it again.
You Make the Decision
GOAT AI summarizes the results with key statistics and the locations that stand out. You interpret them and decide what to share.
all data in one place
Data Integration & Management
Import your own data, connect OGC services, use our built-in catalog, fetch data directly from OSM or Overture, or simply ask GOAT AI to find the data for you.
Built-in Data Catalog
More than 30,000 curated datasets from official open-data providers and trusted sources, ready to use. Ask GOAT AI what each one contains.
Bring Your Own Data
Upload GeoJSON, Shapefile, CSV and other common formats, or connect live to OGC services such as WFS and WMS.
Organise and Share
Keep datasets in folders, share them with your team and control who can view or edit them.
analysis
Spatial Analytics & GIS Indicators
Transform raw geospatial data into measurable insights in seconds. Run accessibility analysis, GIS operations and planning indicators in your browser, or ask GOAT AI to run them for you.
Compute Accessibility Analysis
Perform advanced accessibility analysis with catchments, 15-minute metrics, routing, heatmaps, and public transport indicators (e.g., Swiss ÖV-Güteklassen).
Run Core GIS Operations
Run powerful geospatial analysis tools including spatial joins, data filtering, aggregation, buffering, clipping, and multi-criteria evaluation directly in your browser.
Customize Map Layers
Control basemaps, layer colors, labels, and icons, including attribute-based styling and cartographic customization to produce clear and informative maps.
build once
Automated Spatial Workflows
Automate recurring spatial analysis and cut the manual work. Build a workflow once, or let GOAT AI build it, then reuse it across projects for consistent, reproducible results.
Let GOAT AI Build the Workflow
Describe the analysis in plain language and GOAT AI assembles the workflow. Then check each step and edit what you need.
Build Once and Reuse Across Projects
Build a workflow with drag and drop, or let GOAT AI build it. Then update inputs and parameters and rerun it to save time and keep results consistent.
Document and Share your Processes
Keep workflows transparent and well documented so they can be shared across teams, ensuring consistent methods and faster decision-making.
results
Dashboards, Printed Maps & Visual Analytics
Turn complex spatial analysis into clear, decision-ready insights, interactive or static. Link maps with charts and indicators to create spatial data visualizations tailored for planners, analysts, and stakeholders.
Create Dashboards with No Code
Build interactive GIS dashboards. Connect maps, indicators, and charts in real time to monitor performance and explore urban data.
Generate Print-Ready Maps
Create high-quality maps for reports and presentations. Using the atlas tool, generate map series at once with consistent cartographic design.
Public Sharing & Visual Reporting
Turn analysis into visual reports. Create charts, summaries, and map-linked stats to share insights with decision-makers, stakeholders, and the public.
teamwork
Real-Time Team Collaboration
Collaborate on spatial projects in real time within a multi-user WebGIS environment, without duplicated data or disconnected tools.
Share Work across Teams
Share maps, datasets, workflows, and dashboards with colleagues so everyone works with the same information in a centralized platform.
Work Simultaneously on Projects
Work simultaneously with your team on shared maps, layouts, workflows, and dashboards keeping analyses aligned and maintaining data consistency.
Manage Roles and Permissions
Assign roles and control access across your organization to ensure teams collaborate efficiently while keeping data secure.

Frequently asked questions
What is GOAT?
GOAT is a WebGIS platform that enables spatial analysis, accessibility modeling, GIS dashboards, and collaborative mapping directly in the browser.
What can GOAT AI do?
GOAT AI can find datasets in the catalog, build workflows, run accessibility and GIS analyses, create maps, search your data and calculate statistics. It can also summarize results, for example by naming the areas that stand out. It cannot build dashboards yet, so for now you build those yourself in GOAT, using the results GOAT AI created.
Where are the GOAT AI models hosted?
GOAT AI uses open models hosted in Europe, so your questions are processed in Europe under EU data protection rules. GOAT itself remains hosted on certified servers in Germany.
