For information about changing a layer's priority, see "Specifying General Properties for Layers" on page 159. In Autodesk MapGuide Author, there are two main types of layers: vector and raster. Vector layers contain spatial data that is made up of points and lines, such as cities, countries, and roads. Each vector layer can contain only one type of vector data, either text, points, polylines, or polygons. Raster layers contain spatial data that is made up of tiny squares (pixels) that form an image. An aerial or satellite photograph is a typical example of a raster image. Most of the layers you create will probably be vector layers, which you might place over a single raster image that you use as a background image. If you have Autodesk® GIS Design Server theme data and the Autodesk GIS Design Server Extension, you can create Autodesk GIS Design Server theme layers. If you have Oracle® Spatial data and the Autodesk MapGuide Provider for Oracle Spatial, you can create Oracle Spatial layers. If you have Autodesk DWG files, you can automatically create Autodesk DWG layers. If you have ArcView SHP files and the Autodesk MapGuide Provider for SHP, you can create ArcView SHP layers. Working with Map Layers in the Map Explorer To work with map layers, you use the Design tab of the Map Explorer in Autodesk MapGuide Author. Layers are listed under the Map Layers item. Layers can be part of a layer group, such as the Cities layer group in the following illustration. Layer group Map layers Working with Map Layers in the Map Explorer | 155
