The gap we fill

Map data still moves around as email attachments, or it gets locked in a database nobody else can open.

Teams want a shared editor with an approval trail—and a file they can open in QGIS, ArcGIS Pro, or DuckDB.

Vector Ledger is that hosted workflow. Live today at app.vectorscopeai.com.

Vector Ledger

Setup, Editor, Dashboard, Lake

Create a sandbox, upload a shapefile zip, convert to GeoParquet. People edit on the map. Approvers see the change list. Publish GeoParquet, PMTiles, and a MapLibre preview.

Who it’s for: agencies and orgs that need non-GIS staff to update official map data—and still want real files at the end.

Future architecture

Roadmap: tighter ArcGIS sync, Iceberg tables, heavier GIS production. The live product is Setup → Editor → Dashboard → Lake.

Four parts

Ledger Setup
Sandbox, shapefile zip, GeoParquet

Ledger Editor
Draw and edit on the map

Ledger Dashboard
Proposals, roles, invites

Ledger Lake
GeoParquet, PMTiles, MapLibre

Open files, a real web map

GeoParquet for desktop GIS and analytics. PMTiles and TileJSON for MapLibre. QGIS and ArcGIS Pro can open the lake file.

Iceberg and deeper ArcGIS Online sync are on the roadmap.

Proof: Global Ski Atlas

3000+ resorts, live web editing, versioned data. Same workflow available for agency data (boundaries, infrastructure, program areas).

Today: OSM data · MapTiler, MapLibre, DynamoDB · 3000+ resorts, web editor, public atlas.

It is a related vertical, not Vector Ledger running on Esri.

Why this exists

The usual mess: shapefiles in email, or a geodatabase nobody else can open.

Vector Ledger: hosted editor, approval trail, GeoParquet and PMTiles you can download.

CARTO and Wherobots are strong at lakehouse analytics. We are aimed at the people who still have to change the lines on the map.

Pricing

Ask

Esri Startup Program: we want to be a practical collaboration layer next to ArcGIS, with files agencies can take with them.

Esri software licenses help us test the ArcGIS Pro / Online side of the roadmap.
