Layers are how collected data is organized in Touch GIS. Think of layers as folders that hold groups of collected or imported point, line, or polygon features. Touch GIS offers many features for organizing and managing your data layers.
Access a project's layers by tapping the 'Layers' button in the lower left corner of the screen.
Tip: You can dismiss the layer panel by simply tapping the 'Layers' button again.
Toggle layer visibility on/off by tapping the switch on the layers folder icon. Swithing visibility to off means all features and sublayers will not be displayed on the base map.
To edit a layer's name simply tap on a layer's name in the upper tool bar.
To reorder layers, tap the 'Edit' button in the upper right corner of the layer panel. You'll see drag bars appear. Tap and drag on these bars to move layers up or down in the hierarchy.
To delete layers, tap the 'Edit' button in the upper right corner of the layer panel. You'll see red delete buttons appear next to each layer. Tap the delete button on the layer you want to delete, then confirm your decision.
This feature allows you to create a new sublayer inside the current layer you're viewing.
Number of Features in Layer
This displays the number of features housed inside a sublayer.
To access sharing option for a layer (or entire project if you're viewing the master layer) simply tap Share in the options bar at the bottom of the layers panel.
To import data to your layers, simply tap Import button in the options bar at the bottom of the layers panel.
Move A Layer
Use this feature to move a layer inside or out of another layer.
Set the opacity of a layer and all it's sublayers.
This feature locks a layer, meaning it is visible on the base map but features in that layer are not selectable.
