Exporting Maps Often we want to use maps in PowerPoint presentations, papers or reports. If you do export the image make sure you save the map file so you can recreate the original image at sometime in the future. There are two basic options for transferring maps from ArcMap: 1. They can be copied using ‘Copy Map to Clipboard’ from the edit menu, 2. A copy of the map can be exported into a new format. 1. When copying the map it will be copied as an ESRI Map object with all of the detail and scalability seen in ArcGIS. The image can be pasted directly or, optionally, pasted as an enhanced meta file in the final document. 2. Export Map from the Edit Menu. a. If you are just sending maps to other people it is usually best to send the maps as PDF files. One of the nice benefits of PDF files beyond being transportable they are also searchable for text strings and generally not editable by the end user – what you created is what they will get. ArcGIS will directly export maps to PDF files without having to go through a secondary PDF writer. b. If you want to use a map in a PowerPoint presentation or other Windows package likely you will want to export the file as an enhanced meta file (EMF). Because EMF images are vector based they can be scaled in the importing program without loss of image resolution. EMF images can usually be ungrouped in a CAD or drawing package (even PowerPoint) so different parts can be resized, coloured or modified independent of the other parts of the map. When exporting maps in EMF format any labels and point symbols should be created using a common font or they will not appear correctly, or at all, when opened on another computers. If there is no common font that has the necessary symbols then you can convert Marker Symbols to polygons when exporting in ArcGIS 9.x. In the export dialog box there are options available at the bottom of the screen one of the options under 'Format' is to convert the symbols to polygons. c. JPEG images are a raster format that is often used for presenting information on the WWW, used on a variety of platforms/programs, or can be modified in a graphics package such as PhotoShop. JPEG images are preferred for colour images that will be used on the WWW or some page layout programs. Activity 4. Exporting a Map to Power Point Export the WRHA map layout created earlier with the 12 and 23 regions. Make sure that a legend has been created for the 12 community areas. Add a scale bar and north arrow to the map. Export both a JPEG and EMF image. Read both of these into a different power point slide. Try resizing each image to see what happens to the quality of the image as it gets larger. Ungroup the EMF to see the different ‘parts’ that the map represents.
