Glossary

Access mode

Basemap
The background map under your layers: light, dark or satellite.
Camera
The map's view: centre, zoom, pitch and bearing.
Clean-embed parameters

Connection
A tested link to an external source such as a PostGIS database, an ArcGIS FeatureServer or a WFS.
Dataset

Embed
A published map placed inside another website with an iframe.
GeoJSON
An open format for geographic features and their attributes.

Standard caveat

Read before you rely on a map
Maps show the data their sources contain, at the date and precision of those sources. Locations, boundaries and attributes are indicative. They are not survey-grade, cadastral or legal records, and should be verified on the ground before any investment, land or engineering decision.

Bring your corridor data to the map

Connect a database, a web service or a file, shape the layers, and publish a map your partners can open, embed and question.
