Note: Here is information about the four Google “map types”, as relates to the “Map ZL” zoom-level feature:
Note: In some areas, “Hybrid” and “Satellite” map types may not “zoom-in” past zoom-level 19.
You may enter a “zoom level” manually into the “Map ZL” input box and then click outside the “Map ZL” input box to update the Google map...preferably when the PolyPocket is empty, as any code in the PolyPocket is cleared whenever the “Update Map/Clear PolyPocket” button, or the yellow “U” button, or the blue “GR” button gets clicked.
This Google map web page works best on browsers that are “matchMedia” capable.
Here is a browser compatibility chart with a list of such browsers.
This Google map web page is “mobile-friendly” down to a “320x480-pixels” screen-size. But, due to the nature of maps, the larger the screen this web page is viewed on, the better. And browsers that are not “matchMedia” capable (such as Internet Explorer 9) will not receive automatic “zoom-level” adjustments at smaller screen sizes that optimize the map’s appearance.
The Pocket PolyArc creates extremely precise, pre-formatted 'polyarc' array-code for your Google API Maps...in mere seconds!
And clean-up of errantly-placed map markers is a snap! Just click the 'Remove Marker and Code Line' button on the upper-right of your computer screen, and the last map marker that you’ve generated on the Google API Map will be removed from the map, along with the marker’s associated stretch of red 'polyarc,' and the marker’s pre-formatted 'latitude-longitude' array-code. It’s that easy!
The pre-formatted 'latitude-longitude' array-code for each marker is generated in the 'Pocket PolyArc PolyPocket' that appears on the right-hand-side of your computer screen when you start adding markers to the map.
If you need to remove more than one map marker (and that includes the marker’s stretch of red 'polyarc' on the map, and associated pre-formatted 'latitude-longitude' array-code), keep clicking the 'Remove Marker and Code Line' button until you are satisfied with your polyarc’s course.
Note: The “ZoomLock” feature keeps the Google map at your desired “Zoom Level” after you have clicked the “Update Map/Clear PolyPocket” button! The “Midpoint Polyline” is discussed in the linked-to instructions Example 3. The “Location Popup Window” is discussed on the linked-to instructions Instructions page, under the “Group Section” heading, and is demonstrated in the linked-to instructions Example 4.
