Alright so I've been working on a custom version of leaflet and is currently pretty advanced compared to it's stock counterpart. The problem with it is however that some core functionality isn't required in most custom versions of Leaflet. My problem here is, is it possible to add a search algorithm to the layer control to search for specific layers.
I've tried several plugins that don't immediately search for layers and tried to rewrite them so it works for layers. I've also got the plugin that groups all layers in an expandable group. I'm not the best at google searches but I can't find an answer to this problem anywhere.
Since it's part of police software I can't write any code here without permission, due to the dutch laws (even if it doesn't contain crucial code).
I hope someone can help me with this issue, since it's a huge part of this piece of software. I'll have over 200 layers. They might already be grouped but searching is way nicer and faster in some occasions.
Just post some examples or links below that might work. Thanks for helping in advance!
In your place, I would add all layers to layers-control and leave only the most important ones visible on the map.
I would also add input to the layer-control and searchable in the DOM. I would probably approach this problem in this way.

I've read through the documentation of PDFMake, and PDFKit, and WPS: PostScript for the Web but haven't been able to find any reference to anything other than background layers, from looking at various documentation, it sounds like Optional Content Groups are what I need, but how to handle them using Javascript, I've no idea (I've found little about OCG and layers generally, which isn't sounding promising)!
Any suggestions would be greatly appreciated!
Having tried a few libraries, PDFKit appears to be the best bet, it doesn't discuss layers, but each object you add does exist as a layer, and placing items on top of each other will layer them.
It has been a long time since I have had to do Image Mapping! Probably like 4-5 years.
The last time I achieved this using the tag and creating tags for polygonal shapes. This of course works, and is still supported html, even in HTML5. Question is though, is this still a good way to go for image mapping? Or should i scrap this direction and aim to use Canvas or SVG techniques instead?
There are a couple of factors in regards to the decision:
The client uses IE7, so the solution has to work with IE7 and IE8, hence me thinking not to use SVG or Canvas, it would be easier I guess to use the old school map tag, at least it will easily work across all platforms.
The Map has quite custom styles (strokes around the areas with a margin gap too)
Each area has a rollover state, with a popup with content unique for each region. This will have to be achieved with JS. Are there any issues using JS to interact with the DOM structure of the map using map tag?
It's not essential, but I would to make the map somewhat responsive to the viewport.
Using the tag frankly feels really old school, dated and dirty. But, to be honest for my case, it seems like the most suited solution. What does everyone think?
Any feedback welcome,
Thanks,

For your requirements I think best suite is SVG. By some work around you can make use of all time favorite jQuery with SVG and build cool stuff so quickly. I was able to develope a ticket booking tool on theaters with SVG maps within two weeks.
Also now every one needs every thing on mobile and it works on mobile with just no efforts.
Try to convince client to upgrade IE, that will be best for you. All the best.
I need to display a map of the US and, above that, a layer of states, another of counties and another of places (as per defined by US Census). Also, depending on some criteria, I need to dynamically toggle one layer or another, and to colorize some parts of the layer (e.g. fill some counties in red, others in green, etc). The map itself can be plain simple, I don't need roads or anything that detailed.
My first attempt was done with d3 based on this example, but I'd really like to switch to a tiling-based solution as it seems more responsive, lightweight, smoother and better supported for mobile devices.
I've been looking on the web for a solution (commercial and non-commercial, as a service or locally implementable) but I haven't found one to fulfill all my needs. For example, I've found MapBox which even has a very nice editor, but you can't fine-control the layers you define. I can hide/show a layer, but I can't colorize just a part of it. Google Maps was of course my first option but I didn't find a way to do as above.
Do you know if is there any solution out there that I could use?
I would have a look at the products supplied by boundless. They enable you to use a wide range of technologies and provide the final product in a number of ways. They use Geoserver as a tiling server into which you can output tiles or features depending on what your needs for that layer is.
You can connect to it using ESRI, Quantum GIS or use the included web based map. They are open source so there is a community version that can be used for free or a commercial version that is basically the same but comes with enterprise support.
You can find them here.
Here is my requirement:
I need to create a visualization of links between different representations of a person. The image below I think indicates that fairly clearly.
Additionally, those rectangles would also contain some data about that representation of a person (such as demographics and the place). I also need to be able to handle events when clicking on the boxes or the links between them, as a sort of management tool (so, for example, double clicking a link to delete it, or something along those lines). Just as importantly, since the number of people and links will varies, I need it to be displayed by spacing out the people in a roughly equidistant fashion like the image shows.
What would be a javascript library that could accomplish this? I have done some research and have yet not found something that can cleanly do this but I'm hardly an expert in those libraries.
Here are the ones I've looked at:
Arbor js: Can dynamically create the spacing and links of the graph but I'm responsible for rendering all the visuals and there's really no hooks for things like clicking the links.
jsPlumb: Easily create connections between elements and draws them nicely enough but doesn't seem to address any layout issues. Since I don't know how many people will be on the screen, I have to be able to space them out equidistant and that doesn't seem to be a concern of jsPlumb.
D3.js: This creates a good visualization with the spacing I need but I don't see how I can show the data inside each node or do things like like mouse events on the links or box.
I'm feeling a bit lost so I'm hoping someone could point me to something that could help me or maybe point me to an example from one of these libraries that shows me that what I want is possible.
I ended up using Arbor with Raphael as my rendering library and it's worked out very well.
Take a look at Dracula Graph Library. It's a simple library that seems to do both layout as well as rendering graphs (using Raphael under the hood). It's a bit underdeveloped however.
I've found a feature on two different websites that I'd like to include on one of my web projects, but I can't figure out how they're doing it. I think they're using either jQuery or mootools, but I'm not sure.

I'm new here so I don't have the reputation to post the other link, but if you do a Google search for "Andrews Institute of Orthopaedics" its the top result. I'll see if I can answer a few questions to earn my keep.
The thing that I like about these is that the images and text (including links) are all rotated together. I've done a few web searches related to cycle, rotate and slide but it's not coming together for me. Can anyone give me a nudge in the right direction?
The page you linked is using prototype for this (usually because that's what the author knew, as with most libraries), and it is custom script they've written. However, jQuery has a lot of plugins with various styles, just see what one fits your taste best. I'd suggest taking a look here and a look here.
Anything you find can be automated on a timer like the site you linked, or use buttons, or both. These are all pretty flexible, I'd start by finding the plugin you want, try and get it going, then asking a question here if you have problems getting it to behave exactly how you want.
