The Basics of Google Map
An API key will be generated when you sign for Google Map. Make sure that you save the key as this will be used for all Google Map applications that you may want to use. Google also generates an example page based in Palo Alto area and you may copy and paste the HTML and save it on the web directory.
Google map also responds to various actions by the user such as dragging the map, clicking the interface, or changing the view. You can also write codes at the area you clicked or see the latitudinal and longitudinal coordinates of that area.
Some Map Controls and GMap Features
Google map gives the end user a variety of options. You can zoom in and out, pan, and change the viewing perspective from aerial to hybrid. The Add Control in your GMap has this activities as default.
Furthermore, the OpenInfoWindow method allows you to open information about the area of your interest. Usually, the info window contains HTML information like links, texts and images. Info windows are usually opened just above the area of interest but can be potentially placed anywhere the user desires.
Map overlays are another feature in the GMap. This consists of GMarker, GPoint and GPolyline. The GPoint and GMarker are used to create lines that can be plotted in the Google Map while the GPolyline is used to create a vector between two points. These lines and vectors come in different colors and weights.
Another astounding ability of the GMap is to open and read XML files. It comes handy when reading multiple points of interests and stores this information in an XML file.
The GMap is a very useful tool for drivers who want directions in the United States and Canada, plus it gives the estimated distance and trip time between two locations. You can also search local attractions such as parks, restaurants and other establishments using the GMap and know how to get there.
Using GMap has made it easy and convenient for drivers and tourists alike to get from one place to another. With its high-end applications you can save time and effort looking for the destination you desire… and it’s all free.
