When the upload is complete, the layer thumbnail will have a synchronization icon .

In your Web GIS, you’ll find the uploaded layer with no style.

Note

The number of layers that can be uploaded to Web GIS depends on your subscription plan. On Free plan, you can upload up to 15 layers. To upload more layers, switch to Premium in your account.

Create resource group in Web GIS

When you’re selecting a group for the layer you’re uploading to WebGIS (see Fig. 1070.), in the top right corner there is a folder icon. It opens a dialog for creating a new resouce group in your Web GIS. Enter a name for the group and tap Ok. After the folder is created its name appears in the resource list of the Web GIS:

Configure synchronization with Web GIS

NextGIS Mobile application can access the server at set intervals to share edits and keep layers on the device and in the Web GIS up to date.

To enable synchronization:

1. Open the menu by tapping the three dots in the top right corner .

2. Select “Settings” (Fig. 1078.).

3. Select “Web GIS” section of the Settings (Fig. 1079.).

   • Set up sync interval (between 5 min and 2 hours);

   • Turn on/off synchronization for a particular Web GIS layer.
