Data model: GeoJSON / WGS84 longitude, latitude. Rendering: browser-local Web Mercator.Unsaved example

From coordinates to clear geographic stories.

01 / IMPORT

Make layers of real data

Open GeoJSON files containing points, routes, areas, multipart geometries, or geometry collections. Invalid files report useful errors without replacing your work.

02 / DESIGN

Draw and inspect

Place points, trace lines and polygons, rename features, adjust properties, toggle layers and inspect exact longitude and latitude values.

03 / EXPORT

Hand off with context

Export standards-oriented GeoJSON, a complete editable project, SVG/PNG maps, feature CSV or a Markdown summary.

Frequently asked questions

Are my coordinates sent to a server?

No. Imported geographic data and edits are handled locally. The basemap is bundled, so a tile-server request is not needed. Files are downloaded only when you export.

What coordinate reference system is supported?

GeoJSON coordinates are interpreted as WGS84 longitude, latitude in decimal degrees per RFC 7946. The canvas displays a Web Mercator view. Projected metre-based coordinates or other CRS files must be transformed before importing.

Does this replace a full desktop GIS?

No. This is a lightweight vector viewer/editor—not a GIS analysis engine. It does not perform buffering, raster processing, coordinate transformations, topology correction or surveying-grade measurement. Approximate spherical lengths and areas are for planning only.

Can I reopen and continue editing?

Yes. Save an editable PixelOkay project JSON file. GeoJSON export is intended for sharing geographic features; it does not preserve PixelOkay layer style and visibility settings.

Using GIS & Geographic Data Studio

Open the example or import WGS84 longitude/latitude GeoJSON into a new layer. Draw or edit supported features, organize layers and inspect approximate measurements. Export GeoJSON for data exchange and project JSON to preserve workspace settings.

Web Mercator is a display projection; input/output coordinates remain WGS84. There is no CRS conversion, shapefile/raster import, topology repair or survey-grade measurement. Bounds include 24 layers, 5,000 features and 90,000 coordinates. The bundled simplified Natural Earth outline is for orientation only; imported data is not autosaved, so download project JSON.

Practice: review a fictional feature layer

  1. Open the built-in example or a small WGS84 GeoJSON file you are allowed to use.
  2. Inspect a feature's properties, layer visibility and approximate measurement.
  3. Save project JSON, then choose GeoJSON for data exchange or an image for discussion.

This is an authored mapping exercise, not a survey, a coordinate conversion or a verified boundary dataset.

GIS export questions

Does the Web Mercator display reproject my output coordinates?

No. Input/output coordinates remain WGS84 longitude/latitude. CRS conversion, shapefile/raster import and topology repair are not provided.

Can I rely on the outline and measurements as survey-grade data?

No. The land outline is schematic and measurements use approximate spherical calculations. Imported data is not autosaved; keep project JSON and original geographic files independently.
