The aggregate score based on the app's rating, number of users, and a number of other parameters closely linked to user satisfaction. The TopoNavigator4Pro special edition is addressed to TopoNavigator4 users who want to create aesthetically integral and easily readable maps of professional quality. All extra functions included in TopoNavigator4Pro were developed through a two-year evolution and close collaboration with many corporations, such as travel editions, advertising companies and scientific organizations Along with all the extended possibilities of TopoNavigator normal edition, Pro version also includes a series of tools and settings, aiming to pass the control of the informationΆs density to the user and to make custom symbolizing much easier. Furthermore, it is now possible to create a map image file that contains an even better label placement than the automatic one, so as to obtain a more readable result at regions or scales with rather dense information. This image can be imported in other cartography, or design software (e.g. ArcGIS, AutoCAD, CorelDraw or Illustrator) and, along with some vector layers imported from TopoNavigator4Pro, serve as a base map for more advanced map products.
