![]() ![]() The name of the symbol folder you have created in the Symbols folder in ExpertGPS (Subway, in this example).ģ. The Base URL (), found at the first line of the readme.txt fileĢ. ![]() ![]() The base URL you put at the top of the file should point to a Web site that contains the custom symbols you create, and it has to be constructed in a very specific way, so that ExpertGPS and Google Earth can locate your custom icons.ĮxpertGPS and Google Earth will construct a URL to locate your custom symbols by concatenating three parts:ġ. You must enter a specially-formatted base URL as the very first line of readme.txt The rest of the file is yours to put whatever copyright info you want. The readme.txt file you distribute with your custom map symbols has two purposes – to tell ExpertGPS and Google Earth where to find your symbols on the Internet, and to tell others the copyright and usage info for your symbols. You’ll also need a special text file named readme.txtĬreate a new file, or copy it from one of the other Symbol folders and edit it. You may have to adjust the transparent padding around oddly-shaped symbols like pushpins or arrows so that their tips are centered - there is no way to specify a "hotspot pixel" for individual symbols. When drawing waypoints on the map, ExpertGPS will align the center pixel of your symbol image on the exact latitude and longitude of the waypoint. Important: because ExpertGPS will be creating URLs to the symbols, you cannot uses spaces or special characters in the folder name or the names of any of the symbols you create! If you want to create a symbol called "New York" in a symbol set called "City Metro Symbols", replace the spaces with the underscore _ character, so the folder is named City_Metro_Symbols and the symbol image is named New_York.png Since this location varies based on your Windows settings, the best way to get there is to click Open Program Data Folder on the Help menu in ExpertGPS, and then open the Symbols folder.Ĭreate a new folder named Subway in the Symbols folder, and copy your PNG images there. If your image editor doesn’t support transparency, your logos will appear over a white rectangular background on the map.ĮxpertGPS stores all of its custom symbols in a special folder on your computer. I used Adobe Photoshop (any image editor will do) to create 20×20 pixel transparent PNG files from each logo. I then located the MBTA logo I wanted to use (as well as logos for the transit systems in Chicago, New York, and Washington, DC) at Depending on your project, you might import GIS or CAD data, or retrieve waypoints and tracklogs from your Garmin or Magellan GPS using ExpertGPS. I started by importing free GIS shapefiles containing the subway lines and stations from MassGIS, the official GIS data agency in Massachusetts, into ExpertGPS Pro. In this tutorial, I’ll be creating a system map for Boston’s MBTA system, the oldest subway in the world. By placing your custom map symbols online, anyone who uses ExpertGPS, EasyGPS, or Google Earth can view your maps with the custom markers you created. ExpertGPS allows you to create your own custom map symbols, which you can use on your own maps.
