Browser-local workflow
Your project data stays in the browser.
Files stay in this session
Point data, gridding, contours, PNG export, and grid CSV export run in the local web app.
No account required
Open the workspace, load a sample or your own files, compute, inspect, and export.
Built for lightweight delivery
Use it when a desktop GIS workflow is too much for a focused contour-map task.
Focused by design
Online contour mapping without a heavy GIS suite.
Built for
web0.1 contour maps from CSV/XYZ point data, IDW grids, PNG export, and grid CSV export.
Best for
Consultants, freelance specialists, and small technical teams that need focused map output quickly.
Not for
Replacing a full GIS suite, managing enterprise geodatabases, or building every cartographic workflow.
Roadmap
A clear release path after the core workflow is stable.
Browser-first contour workflow
web0.1 covers CSV/XYZ import, IDW preview grids, local draft cache, undo history, PNG export, and grid CSV export.
Higher-resolution processing
web0.2 will strengthen longer-running jobs, upload boundaries, status polling, cancellation, and high-resolution export tasks.
Specialist mapping controls
web0.3 will add guarded access to advanced algorithms, fault-aware workflows, batch templates, and project snapshots.
Reusable map styling
web0.4 will turn reference styles into editable templates that can be applied to one map or a batch.
Contour Studio
Start from a professional sample map.
Try the workflow before uploading your own data.
