GPolyline Function on Google Map

Google map is an appropriate means to create digital maps. By using the Google map you are given the ease of map-making process. One of the Google Map feature used by the designer of the map is GPolyline. GPolyline function on Google Map is make the points between the coordinates, of the points are later connected to form. 

Google Maps API can receive input coordinates in formats degrees latitude and longitude degrees, minutes and seconds without knowing the signs positive for North latitude and east longitude, while for South Latitude and Longitude West used a negative sign. Please note that Google Maps uses WGS'84 reference ellipsoid, so the data entered must also coordinate using WGS'84 as ellipsoidnya. As an example we will try to create a polyline Indonesia border. Where the Indonesia border have boundary points in the coordinates (7 ° 46'06 "N, 95 ° 33'06" E), (7 ° 5'48 "N, 96 ° 36'30" E),(7 ° 08.05 'N, 96 ° 36.5' E), (6 ° 21.8 'N, 97 ° 54.0E). GPolyline then the script used to create the boundary line is as follows :

var indothai = new GPolyline

([new GLatLng(7.768333,95.55167), new GLatLng(7.085556,96.60139),new

GLatLng(6.352222,97.9),new GLatLng(5.95,98.01806)],"#ff0000", 1);

Make Friends With Google Maps 5.7

With the latest update of Google maps have been blessed with the feature to download the maps explicitly for online use. Community have been waiting in line Google Maps for ages. Even if someone has a subscription mobile network, coverage is never perfect and his face when he is abroad. Google Map 5.7 can be implemented with a androide mobiles.

Google.inc as a company that supports Internet-based services, so I am relieved that they are improving the use of multiple online services. The Google Docs web is also planned to operate offline.

Therefore, what we have now exactly? You can download maps of 10 miles around a particular location. What we can not do, however, plan routes and navigate online within a storage area, and the application does not return any search results when used offline. Basically, you can only map wiev parts, used manually as a printed map on paper. So it's no cap in comparison with the possibilities, but a great start, we are waiting for more improwements.More information about Google Maps 5.7 can be found here.

Working Principle of J2ME Applications with GPS Module

J2ME applications are embedded on mobile devices can utilize existing technology to him. J2ME can use GPRS technology to build an Internet-based applications. Applications on a user (mobile users) can also be enriched with animated graphics, animated interesting by offering ever-increasing user interaction.
Applications built using the J2ME profile MIDP (Mobile Information Device Profile) is known by the name of the MIDlet. MIDP is specifically used on the handset itself with the CPU, memory, keyboard and the screen is limited eg mobile phones, PDAs and so forth. GPS module for tracking devices can be connected with J2ME-based applications, it is necessary configuration. General configuration is as follows.




J2ME-based applications access the GPS receiver built-in. Once the position information is obtained, then the data is transmitted periodically through GPRS connection to the server with the HTTP protocol GPS Tracking.
The working principle own J2ME applications we simplify as follows:

1. Initialization data.
2. Read data from GPS and wait until the GPS position data has been obtained.
3. If the GPS data has been obtained and the data transmission period (eg every 1 minute) has been reached then open the GPRS connection and send data over HTTP to format the URL as above.
4. Repeat step 2, and so on, this process is performed once every 1 second.
5. Implementation of the above will be looping with timer facilities that already exist in J2ME.

Know the J2ME Technology as the Application of GPS Support

J2ME is a combination that exists between a set of Java interfaces that are often referred to as the Java API (Application Programming Interface) with JVM (Java Virtual Machine) designed specifically for the instrument, namely the JVM with limited space. The combination is then used to perform manufacturing applications that run on mobile devices.
J2ME itself basically consists of 3 parts, namely the configuration, profiles, and packages are optional packages. Here's an explanation of the three parts of J2ME :

Configuration is the part that contains the JVM and some other class library. There are 2 pieces of configuration that is provided by SUN Microsystems, the CLDC (Connected Limited Device Configuration) and CDC (Connected Device Configuration). The target device from the CLDC configuration is the small tools, such as cellular phones, PDAs, and pagers. While the CDC is a superset of CLDC, so all the classes are defined in CLDC will exist also in the CDC. Configuration has been provided by the company's tools and placed in the relevant instrument that is ready for use.


Profile is part of the configuration expansion. That is, besides a set of classes contained in the configuration, there are also specific classes are defined again in the profile. The profile is very popular is its use of artificial profiles Sun Microsystems, namely MIDP (Mobile Information Device Profile). Profiles are provided by the company's tools and placed in the relevant instrument that is ready for use.

Optional packages are additional packages required by the application so that when the deployment process for those packages need to be distributed also some part of the application concerned. In contrast to the configuration and profile, if the optional packages are not provided by the companies concerned.

Google Maps and Advantage

Google Maps is Google's free service is quite popular. We can add Google Maps feature that already exists in the web with the Google Maps API. Google Maps API is a JavaScript library. Use / program the Google Maps API is very easy. All it takes is just a knowledge of HTML and JavaScript, and Internet connection.



By using the Google Maps API, we can save time and cost to build a reliable digital map applications, so that we can focus only on the data. Let the world maps data into Google's business only. Currently the last version of the Google Map API is version 3. This version, will appear faster than previous versions especially for mobile browser. We can build a web site that has maps for the iPhone and a phone with Android operating system.

How does GPS work ?

Each region on the earth's surface is covered by at least 3-4 satellites. In practice, each new GPS can receive up to 12 satellite channels at once. Clear sky conditions and free from obstruction to make the GPS can easily capture the signal sent by satellite. More satellites are received by the GPS, the accuracy provided will also be higher.

How it works GPS logically there are 5 steps:

1. Use calculation of "triangulation" from satellites.
2. For to calculation of "triangulation", a GPS measure distance using the travel time of radio signals.
3. For to measuring the travel time, GPS needs require a high time accuracy.
4. For to distance calculation, we must know with certainty the position and the level of a satellite in orbit.
5. Corrects final delay time signal must travel in the atmosphere until it is received receiver.

GPS satellites revolve around the earth for 12 hours in a precise orbit and transmit signal her information into the earth. GPS receiver mengambl that information and by using the calculation "triangulation" to calculate precisely the location of the user. GPS receiver compares the time signal transmitted with time signals received.From the information that can be known how many satellite distance. By calculating the distance range of GPS receiver can perform calculations and determine the position of the user and display the electronic map.

A GPS receiver must lock the signals from at least three satellites to calculate the 2D position (latitude and longitude) and track movement. If the GPS receiver can receive four or more satellites, it can calculate the 3D position (latitude, longitude and altitude). If it can determine the position of the user, then the GPS can calculate other information, such as speed, direction of the destination, route, destination travel, destination distance, sunrise and sunset and many more. GPS satellites transmit information in time so precession because the satellite, which is using an atomic clock. Existing atomic clocks on satellites jalam with atomic particles in isolation, so as to produce an accurate clock than the usual hour.

GPS Functionality

GPS or Global Positioning System, is a device or system that can be used to information the user where he is here on satellite-based earth's surface. To be able to identify where a person is given the tools it needs a GPS receiver which receives signals sent from GPS satellites. The position on the change becomes a point known as waypoint. Waypoint in the form of points of latitude and longitude coordinates of the position of a person or a location is then displayed on the screen on an electronic map. Data sent from the satellite in the form of radio signals with digital data. Wherever you are, then the GPS can help indicate the direction, as long as you see the sky. GPS service is available free of charge, did not even need to pay anything except buy a GPS receiver. GPS receiver module shaped and generate NMEA data containing position data. GPS receiver itself contains several integrated circuit (IC) technology is so cheap and easy to use by everyone. Examples of GPS receivers currently on the market is the Garmin 10x. GPS receiver module has the characteristics of the data can only provide information on the position but were unable to send data over long distances. Therefore, we need technology to transmit data remotely through the Internet. The technology is GPRS (General Packet Radio Service).




At present GPS is implemented on many people's lives. For example, use on aircraft, ships, cargo car. In addition, GPS can also be used for the benefit of individuals (personnal tracking systems), for example, used as vehicle tracking.
In general, the use of GPS, among others:

1. Supports the application of GIS (Geographic Information System) includes monitoring (monitoring), tracking (tracking), pemandauan (guidance).
2. GPS as a means of digitizing the earth.
3. GPS function to correlate the data.
4. GPS is an auxiliary device analysis, because the GPS uses information as a key position to analyze, make inferences, or decided.

After experiencing growth, the GPS currently widely used to meet human needs such as:

1. Navigation system in ITS (Intelligent Transport System). This system can be implemented on a police patrol car, train, ambulance, taxi, car delivery (Courrier).
2. As an ocean transportation navigation systems.
3. In the world of the military, GPS is widely used in tracking the troops and equipment. In addition, GPS is widely used in the enemy's reconnaissance forces.
4. GPS is also used in monitoring forest fires.
