![]() ![]() To register an image using a reference file, click the Load File button and navigate to the folder containing the file. In the case of GeoTIFF images, the MAP View coordinate system is automatically read from the image header-for other image formats, the coordinate system has to be specified manually in the MAP View Editor after the registration process (see more information on Specify coordinate system). When creating a new MAP View, the anchor point and scale are derived from the registration information (placement and image size). It is recommended to use the Image feature type for image registration and for better layer management and workflow. In either case, the Image feature type is the only one available for rasters. Choose either to create a new MAP View based on the image or choose to add the image to an existing MAP View. If the raster image was not imported to a MAP Layer, the Undefined Layer dialog box will appear. If the image is placed on a MAP Layer, the Register Image automatically registers the image using the coordinate system of the MAP View containing that MAP Layer. ![]() With an image selected, click the Register Image button on the MAPublisher toolbar or from the menu Object > MAPublisher > Register Image. Using an embedded, unflattened image with an existing transparency may result in incorrect registration. It will treat images that may have multiple layers as grouped objects and will prevent it from being registered properly. When placing an image, do not use the Convert Layers to Objects option. Register Image can be used on non-spatially referenced images that are already imported to the artboard using the Adobe Illustrator Place command (File > Place) or through Import as an Image feature type. Depending on the image format, check the position and coordinate system of imagery with the data provider before attempting to use this tool. The commonly used GeoTIFF format is embedded with geographic information such as position and coordinate system. Some raster image formats store the relationship between source image coordinates (pixel location) and real-world reference coordinates in an associated reference file but do not save the coordinate system information (e.g. To use Register Image, the geospatial properties of the raster image must be known. Use a product like Avenza Geographic Imager to transform images. Register Image does not have the capability to transform images from one coordinate system to another. If no matching vector data is found in the document, a new MAP view can be created to store the cartographic information of the image to allow for data digitization with accurate positioning. If the coordinate system of an image matches one of existing vector data, the image can be scaled and rotated to fit with the vector data. Register Image uses a coordinate system and coordinates-entered manually or loaded from a reference file-to properly georeference and scale an image. Register Image applies geospatial referencing to images imported to the artboard. ![]()
