Create a layer in vMAP

3 min Medium


Why do I need to create layers?

When you first log into vMAP Portal, the entry page doesn't have any data information or default mapview. In order to make full use of vMAP, you need to create your own vMAP mapview to show and analyse your data on maps.

Mapview is a collection of layers (datasets e.g. points, lines, polygons) with style definitions. That's why you need to create a layer first, then you can import data onto that layer to display on mapview. A mapview can include many layers which contain different kinds of data. It is useful if you want to create a mapview including different kinds of business data, then you can import one data type into one layer, these layers form a complete mapview.   

How do I create a layer?

To create a map layer, follow these steps:

Step 1. In the File button drop-down menu, click addnewlayer to open the Add new layer window shown below.

Addnewlayer1

Step 2.
Type in a layer Name. The layer name is a unique identifier of the layer - no duplicate name is permitted.

Step 3. The Layer group field is only necessary when you want to put multiple layers together in a group. In the Layer group drop-down list, No layer group is the first option and indicates that the new layer is an independent layer.

For creating layer group, please refer to the steps in Manage layer group for vMAP in vMAP Admin Center.

Step 4. Select the Layer type for the new layer. The Layer type is a template for the layer, which defines the type and fields of the layer.

For the details about layer type setting in vMAP Admin Center, please check Create a new layer type.

After selecting a layer type, click show_fields icon to show the included fields within this layer type. 

Addnewlayer4

Step 5. To save the layer, click the Execute button on the Add new layer window .
