Visualization: Geochart - Google Chart Tools - Google Code Overview A geochart is a map of a country, a continent, or a region with two modes: The region mode colorizes whole regions, such as countries, provinces, or states. A Geochart is rendered within the browser using SVG or VML. Examples Regions Example The regions style fills entire regions (typically countries) with colors corresponding to the values that you assign. function drawRegionsMap() { var data = google.visualization.arrayToDataTable([ ['Country', 'Popularity'], ['Germany', 200], ['United States', 300], ['Brazil', 400], ['Canada', 500], ['France', 600], ['RU', 700] ]); var options = {}; var chart = new google.visualization.GeoChart(document.getElementById('chart_div')); chart.draw(data, options); }; </script> </head> <body> <div id="chart_div" style="width: 900px; height: 500px;"></div> </body></html> Markers Example A marker style map renders bubble-shaped markers at specified locations with the color and size that you specify.

A Simple Trip Meter using the Geolocation API Introduction The Geolocation API lets you find out where the user is and keep tabs on them as they move around, always with the user's consent. This functionality could be used as part of user queries, e.g. to guide someone to a destination point. The example here is a trip meter showing the initial location and maintaining a display of the distance they have travelled since the page was loaded. Step 1. You can easily check for compatibility by testing for the presence of the geolocation object: // check for Geolocation supportif (navigator.geolocation) { console.log('Geolocation is supported!') Step 2. In this example, you're building a trip meter, so declare the following HTML: <div id="tripmeter"><p> Starting Location (lat, lon):<br/><span id="startLat">??? The next few steps will use the Geolocation API to populate all those empty spans. Step 3. getCurrentPosition() will asynchronously report on the user's current location. Step 4. Unfortunately, not all location lookups are successful.

LeafLetJs Animating Google Earth (3D) & Map (2D) for Live GPS via Ajax and RestFul Web Service Download demo project - 10.28 KB Introduction I work for a company 'Momentum Technologies' in Australia which provides real time video streaming solutions. For the last couple of days, I have been thinking of making a sophisticated dashboard with live maps (all 3D, 2D, street view), tracking live positions of the camera, streaming video on the side with a whole lot of other information and settings to customize the dashboard view. I started my research and was impressed with bing maps initially but as they revoked their 3D maps feature, I ended up using Google maps for my solution. I also did research on Ajax, Jquery and restful services pattern so that I could interact with server side. Click here to watch the demo video. I am a regular lazy viewer of CodeProject and this is my first article to share the working behind my prototype. Summary The prototype is quite simple and there is no complex logic involved in it. Let's Get Started... Page Design RestFul Web Service Google Earth and Maps

Data URL Maker, Data URL CSS Optimizer and the Data URL Toolkit DATAURL.NET is home to some open source tools for creating and working with Data URLs (RFC 2397). Two of these tools are web-based and available here: Data URL Maker converts files to Data URLs.Data URL CSS Optimizer optimizes CSS files by embedding external images as Data URLs. Various modules, code examples and GUI/command line tools for UNIX systems are available in Downloads. What are Data URLs? Data URLs are a Uniform Resource Identifier scheme that allow you to include data items inline in a web page as if they were being referenced as external resources. History The data URL scheme was defined in RFC 2397 specification of the Internet Engineering Task Force. What do Data URLs look like? Data URLs use the following syntax: data:[mimetype][;base64],[data] Let's say we have a small file icon image we want to embed in an HTML document. This HTML tag would display the following image: Advantages of Data URLs Using Data URLs for the web can have several advantages: Data URLs save HTTP requests.

Leaflet - a JavaScript library for mobile-friendly maps Tool for Google Maps v3 (version 3) This application is also available with Large map. This is a drawing tool for polyline, polygon, polygon with holes, rectangle, circle, marker(icon), direction(route, path). This application uses the Google Maps API Version 3 (V3). It has all the features of Google Maps MyMaps and has direct access to the code for the shapes (overlays) you create. Code will be presented in the textarea. The OpenStreetMap map type has been added to the Google Maps map types. The feature 'polygon with hole' ('donut') is built-in in V3. The V2 feature enableEditing now exists for V3. And for editing - if you have a kml file uploaded on a server, and you want to edit its coordinates, you may use my edit tool Edit tool for Google maps polyline and polygon You will need a PC or laptop with a large amount of computer memory if your kml file has 1000 coordinate pairs or more. If you need to learn how to use KML, this is where you start KML Other useful links:

Geospatial video mapping with Google Earth by SPAR Point Group staff | January 09, 2014 Remote GeoSystems, Inc. has released geospatial video mapping software using Google Earth as a base map for aerial and mobile inspections and monitoring. Called LineVision Google Earth, the application is a video viewer that allows users to geospatially “navigate” a video recording by clicking a location along the aerial or terrestrial GPS track positioned in Google Earth to spatially “forward” or “reverse” the video to that exact location. The video then automatically advances to that point in the video so analysts and subject matter experts can visually interpret what was recorded at that specific place and time. Remote GeoSystems said professional applications include powerline and pipeline inspections, UAV and terrestrial unmanned systems, aerial lidar and mobile mapping projects, border security and narcotics interdiction, road and railway corridor assessment, humanitarian and emergency response and military mission planning and review.

GPS Visualizer map input form: Plot quantitative data This is a special version of the GPS Visualizer map form that's designed for plotting quantifiable data on a map. You can colorize and/or resize the points according to a generic frequency field named "N", or you can use a more typical field, such as altitude, population, or category. If you have track data, or if you don't need to automatically colorize/resize your data points by a particular parameter, you'll probably be better served by the normal Google Maps form, the Google Earth KML form, or the JPEG/PNG/SVG form. The coordinates of your data can be given as latitude/longitude, as geographic places (city-state pairs, states, or countries), U.S. Please contact Adam Schneider, using the address on the bottom of this page, if you have any questions about how this form works!

Maps API The Google Maps JavaScript API v3 is a powerful, popular mapping API.

javascript - Unable to get Mapbox leaflet-omnivore to load markers from .csv Here's the working snippet I've used, and everything works ok: omnivore.csv('teams.csv').addTo(map); However, you don't need to rush into changing the code, because, in your case, any change goes wrong as long as you load your file using the file protocol: instead of loading the file from a web server, using the http protocol: In my case, I use the XAMPP solution stack package, that installs everything I need to host web pages. Therefore, I've created a folder in the htdocs folder, and I've putted the html and the csv files inside: Running on a web server, you'll see that leaflet-omnivore.min.js is loading very quick, under 100 ms!
