In the project “Centering On Moving Vehicle”, we learned how to have the map always centered on a moving vehicle. In this project, we go one step further and show how to have the map also rotating according to the direction of the moving vehicle. In this project, you will also see how to use the CompassAdornmentLayer that always indicates the north as the map rotates.
In the project, “Zoom Levels Partitioning”, we showed how to partition the existing predefined zoom levels to have a finer level of control on how to display layers based on scale. In today’s project, we show how to set your own ten zoom levels based on a reference scale, each zoom level being half in scale of the previous one. So, in this case, we limit the number of zoom levels to ten instead of the twenty predefined ones.
This project shows you how to set the current extent based on a collection of layers. You can use this technique for the common task of having the map set to the full extent. Instead of having to manually set the full extent, now you can pass all the layers you want the full extent to be based on.
