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.

Now

Browser-first contour workflow

web0.1 covers CSV/XYZ import, IDW preview grids, local draft cache, undo history, PNG export, and grid CSV export.

Next

Higher-resolution processing

web0.2 will strengthen longer-running jobs, upload boundaries, status polling, cancellation, and high-resolution export tasks.

Next

Specialist mapping controls

web0.3 will add guarded access to advanced algorithms, fault-aware workflows, batch templates, and project snapshots.

Later

Reusable map styling

web0.4 will turn reference styles into editable templates that can be applied to one map or a batch.
