Configure layer type in vMAP Admin Center

5 min Advanced

What is the layer type used for in vMAP?

Layer type is the template of a layer, which defines the data fields of the points/lines/polygons on the layer. After the layer type is created, you can quickly create more layers with the same layer type for further operations, such as layers with same fields from imported dataset. 

In order to display the spatial data with matched fields in vMAP Portal (front end), you need to configure the layer type before importing data into layers and creating mapviews.
