I want to write an application using openstreetmaps rather than mkmapview, but I'm not sure whether I can add an overlay onto the map. Does this functionality exist?
You should consider http://cloudmade.com/ if you don't want to use MKMapView, or you can use OpenStreetMap data as tiles and use the TileMaps demo
Overlays are basically another layer above maps, so you can reproduce it's behavior yourself.
There's an example from Craig Spitzkoff pre-annotation days you may want to look at: http://spitzkoff.com/craig/?p=108

I'm working with nokia HERE maps and I want to add an additional layer of visualization graphics on top of a map. Since the possibilities to interact, manipulate and customize the graphics created by the HERE api are limited, I would like to work with d3.js/SVG for my visualizations.
My straight forward and obvious solution would have been to just add an absolute positioned SVG element on top of the map and giving it the same dimensions. But of course that takes every possibility to interact with the map. Is there any solution to add an overlay to the map which allows me to put SVG on it while maintaining the full interactivity (panning, zooming, clicking) of the map? Also it should be possible to interact with the SVG.
I know that there is a possibility to add a custom overlay of tiles provided by a tile server to HERE maps but that's not really what I'm looking for. I'm looking for something like the solution google has to offer to this problem. A set of custom layers which are always in sync with the corresponding map and have their own initialize, draw and remove methods. Is there something similar for HERE maps?
I think you are after the nokia.maps.map.provider.CanvasProvider class. This class provides a ground overlay bound to a specific area which offers a draw() method. The attach() method is the equivalent of your intialize I think, and you can refresh the overlay using update().
Depending upon your use case, I've also found the following techniques useful regarding SVG, Images and HERE Maps:
For an SVG marker which is anchored to a point and doesn't resize
use: SVG Markers
Alternatively override the Marker class and write using the low
level graphics commands to add flexibility to the rendering of a
marker anchored to a point. Like this: Defaced Marker
To add an image bound to a specific area use the ImageProvider class
To add a series of tiled images from a TMS (Tile Map Service) use the ImgTileProvider class
Alternatively if the [zoom][col][row] is useful to you and you
want to write SVG based stuff yourself try something like this example - which combines
SVG with 256x256 pixel markers.
Note that the HERE Maps API for JavaScript only supports SVG Tiny.
A class like the old nokia.maps.map.provider.CanvasProvider isn't even available on the new v3 API from Here.
Your best bet is on Leaflet using custom providers loading Here map tiles. Then you just load this Custom Overlay class and you're all set to draw D3, WebGL, whatever you need. Leaflet only loads the tiles from the providers and exposes some simple APIs. You will not have to deal with any of the providers' APIs.
Just don't forget to add your app_id and app_code to the provider class.
I would like to create a JSF web application to display a graphic structure (composed of hierarchical elements organised in a database) where, if possible, the user could eventually zoom in/out, add new elements...
But I haven't been able to identify a single JSF component (or compatible component) to help me do that.
This is what I would like : http://www.yworks.com/products/yfileshtml/demos/Complete/demo.yfiles.graph.orgchart/index.html
But it's not free and not in JSF.
I thought of the PrimeFaces mindmap component, but it is not compatible with IE8 and this is a requirement for my projet...
My second thought was to use RichFaces' Paint2D to manually draw info in rectangles and links between rectangles with calculated coordinates, but this seems a bit complex...
http://livedemo.exadel.com/richfaces-demo/richfaces/paint2D.jsf?c=paint2d
A final thought was to use CSS to display rectangles, but I can't display links and interact with the structure...
Any better idea ?
Thank you for your help !
OmniFaces has a component for creating a hierarchical tree.
Maybe you could use that to display a custom markup, and work out a way to manipulate it with Javascript, in order to get the behavior you want.
If that is not feasible, I'd suggest you to study a little bit of HTML5 Canvas, see what you can do with that. You can get inspired here checking out this is open source (GPL) HTML5 mind map app, the code is at GitHub.
I am trying to create an interactive map where users can click on different provinces in the map to get info specific to that province.

So far I've only found solutions that have limited functionality. I've only really searched for this using an SVG file, but I would be open to other file types if it is possible.
If anyone knows of a fully functioning way to do this (jQuery plug-in, PHP script, vector images) or a tutorial on how to do it manually please do share.
jQuery plugin for decorating image maps (highlights, select areas, tooltips):
http://www.outsharked.com/imagemapster/
Disclosure: I wrote it.
Sounds like you want a simple imagemap, I'd recommend to not make it more complex than it needs to be. Here's an article on how to improve imagemaps with svg. It's very easy to do clickable regions in svg itself, just add some <a> elements around the shapes you want to have clickable.
A couple of options if you need something more advanced:
http://jqvmap.com/
http://jvectormap.com/
http://polymaps.org/
I think it's better to divide my answer to 2 parts:
A-Create everything from scratch (using SVG, JavaScript, and HTML5):
Create a new HTML5 page
Create a new SVG file, each clickable area (province) should be a separate SVG Polygon in your SVG file,
(I'm using Adobe Illustrator for creating SVG files but you can find many alternative software products too, for example Inkscape)
Add mouseover and click events to your polygons one by one
<polygon points="200,10 250,190 160,210" style="fill:lime;stroke:purple;stroke-width:1"
onmouseover="mouseOverHandler(evt)"
onclick="clickHandler(evt)" />
Add a handler for each event in your JavaScript code and add your desired code to the handler
function mouseOverHandler(evt) {};
function clickHandler(evt) {};
Add the SVG file to your HTML page (I prefer inline SVG but you can use linked SVG file too)
Upload the files to your server
B-Use a software like FLDraw Interactive Image Creator (only if you have a map image and want to make it interactive):
Create an empty project and choose your map image as your base image when creating the new project
Add a Polygon element (from the Shape menu) for each province
For each polygon double click it to open the Properties window where you can choose an event type for mouse-over and click,
also change the shape opacity to 0 to make it invisible
Save your project and Publish it to HTML5, FLDraw will create a new folder that contains all of the required files for your project that you can upload to your server.
Option (A) is very good if you are programmer or you have someone to create the required code and SVG file for you,
Option (B) is good if you don't want to hire someone or spend your own time for creating everything from scratch
You have some other options too, for example using HTML5 Canvas instead of SVG, but it's not very easy to create a Zoomable map using HTML5 Canvas,
maybe there are some other ways too that I'm not aware of.
Just in case anyone will search for it - I used it on several sites, always the customization and RD possibilities were a perfect fit for what I needed. Simple and it is free to use:
Clickable CSS Maps
One note for more scripts on a site: I had some annoying problems with getting to work a map (that worked as a graphic menu) in Drupal 7. There where many other script used, and after handling them, I got stuck with the map - it still didn't work, although the jquery.cssmap.js, CSS (both local) and the script in the where in the right place. Firebug showed me an error and I suddenly eureka - a simple oversight, I left the script code as it was in the example and there was a conflict. Just change the front function "$" to "jQuery" (or other handler) and it works perfect. :]
Here's what I ment (of course you can put it before instead of the ):
<script type="text/javascript">
jQuery(function($){
$('#map-country').cssMap({'size' : 810});
});
</script>
Go to SVG to Script
with your SVG the default output is the map in SVG
Code which adds events is also added but is easily identified and can be altered as required.
I have been using makeaclickablemap for my province maps for some time now and it turned out to be a really good fit.
I had the same requirements and finally this Map converter worked for me. It is the best plugin for any map generation.
Here is another image map plugin I wrote to enhance image maps: https://github.com/gestixi/pictarea
It makes it easy to highlight all the area and let you specify different styles depending on the state of the zone: normal, hover, active, disable.
You can also specify how many zones can be selected at the same time.
The following code may help you:
$("#svgEuropa [id='stallwanger.it.dev_shape_DEU']").on("click",function(){
alert($(this).attr("id"));
});
Source
You have quite a few options for this:
1 - If you can find an SVG file for the map you want, you can use something like RaphaelJS or SnapSVG to add click listeners for your states/regions, this solution is the most customizable...
2 - You can use dedicated tools such as clickablemapbuilder (free) or makeaclickablemap (i think free also).

I am new to opengl and visual c++. I have done a sample application which rotates 3D shapes in opengl. I want to allow the user to rotate and zoom the object. Please give me an example of how to do this.
I have tried NeHe tutorial: http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=48
I can't understand the class structure in the example. Is there anysimple way to achieve this?
I have found a library as well: http://www.nigels.com/glt/gltzpr/
But still can't figure out how to do this.
Please help me.
Zooming is usually done through gluLookAt. The third parameter is the view distance.
Here is some basic example running this :
http://graphics.stanford.edu/courses/cs248-01/OpenGLHelpSession/code_example.html
Look in display() to see how the viewing distance is used and in MouseMotion() to see how the value is modified and the painting updated.
I need to build a custom designed bar chart that displays some simple data. Below are my requirements. Can anyone suggest the best web technology for my requirements.
high browser compatibility
ability to draw shapes
ability to fill shapes with gradients
ability to have onclick and onmouseover events for the different shapes (bars in the chart).
Thanks guys. I was thinking of using svg but looking for suggestions.
How about Raphaël - it's SVG/VML.
It says:
Browser compatibility:
Raphaël currently supports Firefox
3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+.
Ability to draw shapes
circle, rect, ellipse, image, text, path
Ability to fill shapes with gradients
yes
Ability to have onclick and onmouseover events
yes:
... every graphical object you
create is also a DOM object, so you
can attach JavaScript event handlers
or modify them later.
Everything in the reference
On top of that, there's a plugin called gRaphael which makes the creation of charts easier.
Simple data - Google Charts API or Google Visualization API may suit you.
Details for all features of image charts can be found on the Chart feature list
You may also take a look at the comparison of the Charts API and the Visualization API.
Another candidate of course is JQuery SVG - if you're already familiar with jquery you may prefer this one.
There's a comparison of JQuery SVG and Raphaël on SO:
jQuery SVG vs. Raphael
I recommend using Adobe Flex. Below is an example of how easy pie chart creation can be in Flex:
<mx:Panel title="Pie Chart">
<mx:PieChart id="myChart"
dataProvider="{expenses}"
showDataTips="true"
>
<mx:series>
<mx:PieSeries
field="Amount"
nameField="Expense"
labelPosition="callout"
/>
</mx:series>
</mx:PieChart>
<mx:Legend dataProvider="{myChart}"/>
Based on your criteria:
high browser compatibility: Flex is used on more than 95% of all browsers and behaves the same in all browsers. No more need to check if your web app is running in ie, firefox, chrome, etc... because any browser that has a flash player is compatible.
ability to draw shapes: Flash's greatest strength is the ability to draw. Charts are completely customizable and skinnable to achieve the look you need.
Ability to fill shapes with gradients - done easily by setting style attributes or a custom skin.
ability to have onclick and onmouseover events for the different shapes - see this link for some easy ways to create user interactions with charts.
Hi i hope this link may help you i found it while searching for a solution similar to what you're looking for:
http://www.artetics.com/Articles/using-various-javascript-libraries-to-create-pie-chart
i'm trying gRaphael, i'm having difficulties on finding documentation though. you have to read the code and use the exploded instead of the min.js
I would like to share jquery.jqplot.js. It has lots of jQuery options, but depends on other plugins such as syntaxhighliter etc.
