Raster (or image) files are pixel-based data, such as digital photographs, that you can use as backgrounds for feature and drawing data. For example, you can display an aerial photograph of a city under a layer of streets.
Image files can be very large, especially if they cover extensive areas in detail. To make them easier to handle, images are often broken down into “tiles,” which cover smaller areas. Each individual image file can be georeferenced, that is, it has an associated file (for example, TFW for TIFF files) that specifies the location of the image within the coordinate system used in the map.
In AutoCAD Map 3D, you have two ways of bringing tiled images into your map when you use the Raster Provider in Data Connect:
- Bring each image onto its own layer. You can easily turn each individual tile on or off. If you place them in a single folder in Display Manager, you can turn them all on or off at the same time.
- Bring
multiple image tiles onto the same layer. This is useful if you
want to make a single photo background from a mosaic of individual
image tiles.
