CSA Loom — the Microsoft Fabric experience for Azure tenants where Fabric isn't yet available: lakehouses, warehouses, notebooks, semantic models, Activator rules, Data Agents, across Commercial, GCC, GCC-High, and DoD IL5

Tutorial: Map editor

CSA Loom map editor — verified working against a live console by the UAT harness on 2026-07-01.

Open the editor

  1. Sign in to your CSA Loom Console (for example https://<your-console-host>).
  2. Open or create a workspace from the Workspaces page.
  3. Click + New item and choose Map from the catalog.
  4. The editor opens at /items/map/<id>:

Map editor

What this editor does

A Map is a geospatial visualization layered over Lakehouse, KQL, and Ontology data. In Loom the map binds to a live Azure-native source — a Synapse Serverless table (Lakehouse), an Azure Data Explorer KQL query, or a Weave Ontology entity — and renders point, heatmap, cluster, and choropleth layers over the returned geo rows. No Power BI / Fabric required; the vector overlay renders offline and an optional Azure Maps raster basemap layers behind it.

Getting started

  1. Bind a geo-dataset — On the Data binding tab, pick Lakehouse / KQL / Ontology, map the lat/lon (and optional value/label) columns, and Run binding — Loom queries the real backend and folds the rows into the map.
  2. Add layers — Compose point, heatmap, cluster, or choropleth layers over the bound data; each can be weighted by a numeric value column/property.
  3. Style and color — Set color ramps and symbology so the geography reads clearly.
  4. Draw and measure — Toggle Draw / measure to sketch points, lines, polygons, rectangles, and circles directly on the map with a live spherical distance / area readout; drawn annotations persist with the map.
  5. Geocode addresses — Paste addresses (one per line) in the Geocode addresses box on the Data binding tab and Geocode & plot — Loom resolves them to lat/lon via Azure Maps Search and plots the points (use Use bound labels to geocode an address column you already bound). Requires the Azure Maps account wiring; a missing account surfaces an honest gate.
  6. Embed it — Embed the map in a report or dashboard for consumers.
