252Part III: Digital Mapping on Your ComputerTo demonstrate the process of calibrating a map with OziExplorer, use ascanned copy of a 1:100,000 scale USGS topographic map. (Check outChapter 21 for sources of free maps.)FUGAWI is a popular Windows mapping programwith some of the same basic features asOziExplorer.Like OziExplorer, FUGAWI can read a number ofdifferent map formats with georeferenced dataFUGAWIas well as use do-it-yourself, calibrated, scannedimage maps. The program can also interfacewith a GPS receiver and handle waypoints,routes, and tracks. See a FUGAWI map in thefigure here.Comparing FUGAWI with OziExplorer, you’ll seethat FUGAWI isn’t shareware, it’s priced a littlehigher, and it comes bundled with a base set ofmaps.FUGAWI and OziExplorer both have extremelyloyal user bases. If you check around the Internet,you’ll see some strong feelings expressed aboutwhy one product is better than the other. (I thinkOziExplorer has a better user interface and supportsa few more advanced features.) If you’reconsidering FUGAWI or OziExplorer, downloadthe free demo versions of each program and seewhich one you prefer.For more information about FUGAWI and todownload the demo version of the software, visitwww.fugawi.com.
