Cesium JS

Cesium JS is an open source JavaScript application used to display 2D and 3D Geospatial models from an application.

CesiumJS is an open source JavaScript library to display World class 3D Globes and maps with the best performance, precision, visual quality and ease of use. Developers across industries, from aerospace to smart cities to drones, use CesiumJS to create interactive web applications for sharing dynamic geospatial data.

This is what it looks like below, at embed from spaceaware.io , a web that displays an interactive web application for the movement of satellites around the earth.

To see the movement of the satellite you can point Curson to the bottom left, to the white point, and set the time frame movement as desired, and you can display the status of the satellite in the image by clicking on the satellite points and displaying the satellite's trajectory. Meanwhile, to display 2D or 3D images, it can be arranged on the top left menu, by clicking on it and adjusting the appearance.

Free Live Map Javascript for your Marine Traffic

Live map of marine traffic for the status of your company's ships, which can be applied to your website. With the Javascript code below, you can install marine traffic maps on your own website. It's easy to do this by inserting the following line of code into the HTML of your web page, at the point where the map will be displayed: or if you want to configure the map dimensions, center area, zoom level and even the positions of your company's ships that you want to observe, use the following code and adjust the default value

the following is the script code:

width='100%'; // the width of the embedded map in pixels or percentage

heights='450'; // the height of the embedded map in pixels or percentage

border='1'; // the width of the border around the map (zero means no border)

shownames='false'; // to display ship names on the map (true or false)

latitude='37.4460'; // the latitude of the center of the map, in decimal degrees

longitude='24.9467'; // the longitude of the center of the map, in decimal degrees

zoom='9'; // the zoom level of the map (values between 2 and 17)

maptype='1'; // use 0 for Normal Map, 1 for Satellite

trackvessel='0'; // MMSI of a vessel (note: vessel will be displayed only if within range of the system) - overrides "zoom" option

fleet=''; // the registered email address of a user-defined fleet (user's default fleet is used) - overrides "zoom" option

</script>

You can set the width and height of the map/map, as well as add ship names by changing the shownames status to true, and setting the map/map display according to your long lat area. And you can also display a normal map view or a satellite map by changing the maptype value

In the program below latitude and longitude, I changed it to the latitude and longitude of the Indonesian region.

latitude='6.1750';

longitude='106.8283';

Google Chart Tools

Google Chart Tools help display live data on your site. You may check out the rich gallery of interactive charts and data tools provided by google charts.

Using Google charts, you can create ready-to-use charts that you embed in your website. You usually load some google chart libraries, provide the data to be graphed, select options to customize your chart, and finally add the javascript for your chart.

Example Google Chart using Pie Chart :

<html>

<head>

// Load the Visualization API and the corechart package.

google.charts.load('current', {'packages':['corechart']});

// Set a callback to run when the Google Visualization API is loaded.

google.charts.setOnLoadCallback(drawChart);

// Callback that creates and populates a data table,

// instantiates the pie chart, passes in the data and

// draws it.

function drawChart() {

// Create the data table.

var data = new google.visualization.DataTable();

data.addColumn('string', 'Topping');

data.addColumn('number', 'Slices');

data.addRows([

['Mushrooms', 3],

['Onions', 1],

['Olives', 1],

['Zucchini', 1],

['Pepperoni', 2]

]);

// Set chart options

var options = {'title':'How Much Pizza I Ate Last Night',

'width':400,

'height':300};

// Instantiate and draw our chart, passing in some options.

var chart = new google.visualization.PieChart(document.getElementById('chart_div'));

chart.draw(data, options);

}

</script>

Google Chart Galleries

To help you visualize your data, Google provides a number of charts gallery to help visualize your data needs. Our Google Chart provides a variety of charts to help you visualize your data. You can use our charts to see how your data is distributed, how your data changes over time, or how your data compares to others.

Type of Google Charts :

Geo Chart, Scatter Chart, Column Chart, Histogram, Bar Chart

Combo Chart, Area Chart, Stepped Area Chart, Line Chart

Pie Chart, Bubble Chart, Donut Chart, Org Chart, Treemap

Table, Timeline, Gauge, Candlestick Chart

Geo Chart :

A geochart is rendered within browser using SVG or VML. It is not scrollable or dragable , a geochart identified with one of three ways :

The region mode colors whole regions, such as countries, provinces, or states.

The markers mode uses circles to designate regions that are scaled according to a value that you specify.

The text mode labels the regions with identifiers (e.g., "America" or "Europe").

Region Charts

Fills the entire regions countries with colors

<html>

<head>

google.charts.load('current', {

'packages':['geochart'],

});

google.charts.setOnLoadCallback(drawRegionsMap);

function drawRegionsMap() {

var data = google.visualization.arrayToDataTable([

['Country', 'Popularity'],

['Indonesia', 500],

['Vanuatu',200],

['Australia',500],

['Saudi Arabia',600],

['China', 700],

['Brazil', 300],

['Canada', 500],

['France', 600],
