TIN Surveys¶

The TIN Surveys grid can be accessed by right clicking the TIN Surveys layer in the TIN Surveys folder of the Layer Tree and selecting Open Data Grid from the context menu.

Note

No geometries are displayed for the initial read-only LA-Wide Import of Segment Impact Codes TIN survey as this covers the whole road network. This is to avoid performance issues in the browser, and prevent hiding individual surveys. These surveys have a padlock icon in the top-right indicating they cannot be edited.
