What is the basics of Google maps and Google geolocation APIs. The maps API documentation was not published, but many developers already started experimenting as soon as the BETA was released.
In addition to providing a useful service, it has wanted to go even further by making a very plastic interface in which the maps flow easily in our browser, this feature makes it a very absorbing system for the user.
The maps are based on Javascript technology, which undoubtedly makes our lives easier, since you do not need to install any software and is compatible with practically all browsers, Firefox, Mozilla, Opera, Internet Explorer, Netscape… From Either way you can use the GBrowserIsCompatible() method to check for compatibility and display an error message if necessary.
However, it also offers us some limitations:
Updated: Please note that the first release of these limitations may have been resolved in modern versions, as the article and this listing were initially published in 2007.
- It does not provide a geocoding service, that is, you must provide the latitude and longitude of the desired location, which means that you must trust third-party geocoder tools to obtain the latitude and longitude of a given address.
- The one provided by Google to generate maps is limited to a single URL, which forces us to have a website for the development of applications.
- The is only valid for a directory of our website
- It can be used for commercial purposes, but it must be available to end users free of charge, it can also be used on protected sites as long as the authentication is free.
- Its use and traffic is not restricted but if you have more than 50,000 visits you should contact Google.
Updated: Yahoo! maps. We’re sorry.
Yahoo Maps also has its own API with some significant differences, from my point of view the biggest difference is that yahoo offers Geocoder.
Here is a small comparison:
Only accepts longitude and latitude Does not have a geocoder Provides its own geocoder Maps can be generated on any page with its corresponding Key Maps will only be generated in Yahoo Uses Ajax Does not use Ajax Can be used for commercial purposes as long as it is free for the user final Can be used for commercial purposes but written authorization is required You can add HTML or XML text in a small information window You can add HTML text in a small information window and allows the use of IFRAMES Its use is not restricted to a reasonable limit No restriction of use
Find a Geocoder tool
There are several free geocoder tools that provide latitude and longitude of an address but these are not Spanish so their use is limited but don’t worry there are solutions.
