Introduction
Given that we have WinCan VX at our fingertips for handling all of our data and WinCan Map VX as a connected and/or standalone GIS application, we should where possible take full advantage of the features in WinCan Map to help keep the data organised and make life simple for the site teams doing the inspections.

Working with Background Tiles
Background tiles (or Ordnance Survey MasterMap layers) are extremely useful for showing just the general geometry and layout of the road and the surrounding areas, and they can usually be relied on quite comfortably for a reasonable level of accuracy.

Note – you may see that your data and point objects in Map have disappeared. This is because you have added the background layer as an external layer, and when you add new layers to WinCan Map, they are always added at the top of the layers list.
Because this layer is made of shapes filled with colour, you have effectively thrown a blanket over the other layers in your project.
To fix this, right-click on the layers and use the Layer Up, Layer Down, Layer Top and Layer Bottom options to rearrange them. They will always be rendered on the screen in the order from top to bottom that they are listed in the Layers Panel. It’s a good idea to always put the background layer at the bottom of the pile.
