Overview

Archived: In this article, we create an API to retrieve static maps using the GoogleMaps® system. So, in this way, your work can be so much easier using this API made for JavaScript.

To get this API click: http://embedded.ufcg.edu.br/~artur/Maps/Map.zip and to see the API documentation click http://embedded.ufcg.edu.br/~artur/Maps/docs/index.html.

Examples

Now, we'll see some examples illustrating the use of the Map API.

Showing Maps Automatically

One way to retrieve the map is using the <div> tag. Put all the values you want to your map and use the showMap() tag. It's really necessary that you set the map id with the same value of the div.

<body onload="init();">
<div id=map></div>
</body>
/**
* Embedded Systems and Pervasive Computing Lab
* WRT Effort - http://efforts.embedded.ufcg.edu.br/wrt/
*
* @author Artur
*/

function init() {
map = new Map(40.702147, -74.015794);
map.id = "map";
map.color = "green";
map.name = "y";
map.width = 400;
map.height = 200;
map.showMap();
}

Retrieving the map's source

Other way to retrieve the map is using the <img> tag. You set the parameters and using the method getSource() you can define the src value.

<body onload="init();">
<img src="" id=map>
</body>
/**
* Embedded Systems and Pervasive Computing Lab
* WRT Effort - http://efforts.embedded.ufcg.edu.br/wrt/
*
* @author Artur
*/

function init() {
map = new Map(40.702147, -74.015794);
map.color = "blue";
map.name = "x";
map.width = 300;
map.height = 300;
document.getElementById("map").src = map.getSource();
}

So,

Using external data source, like GPS

First, getting the GPS information. You define the device operations:

/**
* Embedded Systems and Pervasive Computing Lab
* WRT Effort - http://efforts.embedded.ufcg.edu.br/wrt/
*
* @author Artur
*/

function setup()
{
try {
so = device.getServiceObject("Service.Location", "ILocation");
getLocation();
}
catch (e) {
alert('(006) Error ::setup ' + e);
}
}

After that, the get location method:

function getLocation() {
try {
var updateoptions = new Object();
updateoptions.PartialUpdates = false;
 
var criteria = new Object();
criteria.LocationInformationClass = "GenericLocationInfo";
criteria.Updateoptions = updateoptions;
 
var result = so.ILocation.GetLocation(criteria, result);
var errCode = result.ErrorCode;
if (errCode) {
alert("(005) GPS Error: " + errCode + " " + result.ErrorMessage);
}
} catch (e) {
alert("(004) ::getLocation error: " + e);
}
}

Finally, the call back function:

function result(transId, eventCode, result)
{
var errCode = result.ErrorCode;
if (errCode) {
alert("(003) GPS Error: " + errCode + " " + result.ErrorMessage);
}
else {
map = new Map(result.ReturnValue.Latitude,
result.ReturnValue.Longitude);
map.id = "map";
map.color = "yellow";
map.name = "Artur";
map.width = 500;
map.height = 250;
map.showMap();
}
}
