Only one layer can be 'active' at the Reference Panel, to see which layer is active it's name has a light-green background. To make a layer active, just click on it's name
In GeoAgro GIS, operations and commands are executed on the active layer, one of them is 'Edit cartography and layer properties'
To make the layer 'Fields (NRCS)' invisible, please click on the eye icon belonging to it and clear the visibility checkbox
The eye icon will change it's color to grey
And 'Fields (NRCS)' will not be visible on the map
And 'Fields (NRCS)' will be visible on the map
You can also hide or show an entire groups of layers, by clicking on the checkbox next to the group's name.
If you check the visibility box and it isn't drawing, it may be hidden by another layer on top of it.
On the image above all layers below 'Orthophoto' are hidden, and that is not because they are in 'Invisible mode' (please note that the eye icon is still orange).
The reason why they are not shown is because they are below an opaque layer, in this case 'Orthophoto'
For this reason, it's a common practice to order the layers following these tips.
- Point and Polyline layers on top.
- Below them the Polygon ones (but you can always use hollow Polygons).
- And at the bottom the Raster layers, such as Topographic maps (DRGs) and Satellite imagery.
There's a second method to handle the visibility of layers, by adjusting their transparency level.
The Orthophoto currently has no transparency, you can check that by clicking on the eye icon: you'll see that the level bar is at the top of the slide
Please drag the slide control a quarter down.
You'll notice that the layers below Orthophoto are now partially visible.
To make them even more visible, just repeat the process lowering the transparency level until you're satisfied.
