Drawing polygons on Google Maps - javascript

I was drawing polygons using Polygon Creator Class on Google Maps. As you see this tool is not easy to use. For example, it's impossible to add new polygon or edit some of them after getting result code.
In following link when you zoom in between polygons you will see gaps that I want to remove. To recreate the issue please open following link and zoom in between polygons:
http://jsbin.com/bovogaqowu/1/edit?js,output
Now question is, how to remove gap between these polygons ? In this case I can't use the tool that I used to create this map.
And which tool is better to use in this situation ?
Thank for your time

I would suggest you using the Google's official tool for drawing, editing, locatiing and even finding driving directions for the markers you have placed on the maps. You can always save these edited maps and retrieve them later when you need them.
Please click the following link and get started!!
Even I tried drawing some polygons side by side and there were no gaps :)
Hope this would help!!

Adding multiple icons to a pushpin with Bing maps api v8

Bing maps v8 - I am trying to represent more than one icon/symbol at a particular location in the map.
For example, at a particular location, i want to have a pushpin that denotes the location plus I want to have another icon/symbol below the pushpin which represents the severity of the location say (highly crowded - red, moderately crowded - yellow, and less crowded - green).
I am not interested in showing this in the pushpin (image) itself, but I want to have it under the pushpin image along with the title of the location.
With version 7 of bing maps, it was possible to add - atleast a border with different color for puspin image which would satisfy my requirement, but in v8 bing maps it is not possible to add custom CSS/HTML.
Also I want the puspin to be draggable. There are HTMLPushpins but they do not supply proper dragging of pushpin.
Any help at the earliest or need more info? Thanks in advance!
A sample image : As you see the markup in the following link works, but it just does not work in bing maps I dont know why!

I highly recommend taking a look at using SVG templates for pushpins. This will allow you to easily change the color using the shapes color option. Here is a tool that provides some examples of different SVG pushpin templates: http://bingmapsv8samples.azurewebsites.net/#SVG%20Pushpin%20Maker
If you can provide a screenshot of the pushpin you want to create, I can see if I can put together an SVG template that matches it.

How do you create custom interactive areas on Google Maps?

I'm trying to create a map that shows county/district areas using Google Maps that will allow users to click on the area to retrieve relevant pop up information.
I have two datasets that I think would help, one being a list of UK Postcodes which would in turn allow me to determine different postal areas and the other is a dataset from Ordance Survey that contains province borders (county/district borders).
I've looked into KML Files and ImageMap but I'm not sure how to create these areas using the data I have?
I'm looking to achieve the sort of map that is used here:
http://content.met.police.uk/Page/YourBorough
Any help is greatly appreciated!
Thanks.
The way to work with Google maps is by using their api closely. You cannot go with simple image mapping.
Try those two links for starters:
https://developers.google.com/maps/documentation/javascript/examples/polygon-simple
and
https://developers.google.com/maps/documentation/javascript/reference#Polygon.
In short - you may need to draw a polygon for every area, bind a click event to it, then show Info Window with the relevant information for the user.
In case you're new to google maps, you may need to take more time inspecting their Api and the examples they give.
Best regards.

highlight building google maps v3

Im trying to highlight specific building within a map using the google maps v3 api. I was wondering if anyone had any idea how to do this. I've been looking through google api documentation and come across nothing at the moment.
For example: http://goo.gl/maps/GyrDB - This is a map of a section manhattan, as you can see the 3d building. Im trying to highlight specific ones on hover.
Thanks :D
If you have information about where the building is, then you can use a Polygon to highlight it. If you don't have information about where the building is, then you are probably out of luck. The Google Maps API doesn't have any way of interacting with the map at that level.
Now, I suppose that one thing you could do is:
download the Google Maps tile,
find the point in the image that the user clicked on,
do a flood fill of that point with some awful colour,
set to clear all the pixels which are not the colour,
overlay that image on top of your map
You would also need to be clever about buildings which lie in more than one tile.
HOWEVER, this might run you afoul of the Terms of Use. I know that they disallow modifying the artwork; I am not sure if this would count as modifying the artwork; you'd need to look carefully at the TOU and maybe ask a lawyer. Or ask Google. (Don't ask me, I am not a lawyer.)
In many countries, every building is a cadastral parcel and there Web Map Service (WMS) layers showing them, provided for free by state bodies.
Using these layers, you can get building polygon coordinates. For ex: https://snag.gy/WtU7ZT.jpg

tiled textures across a google map in javascript

Using the google maps v3 javascript API, it's possible to add 'GroundOverlays' as a picture. Have a look here:
http://jsfiddle.net/9YYJB/1/
However, I'm working on a project where I'm trying to add a texture to the whole world map. Obviously I can add a single, absolutely massive gif/png overlay but I'd rather add a tiling texture. I've been digging around in the API and can't find any way to do this.
Anyone have any ideas on how this could be done?
Thanks very much
Yes, what you want to use is an image map type. This allows you to add tiles on top of the regular Google Base Map. If you want to completely replace the Google tiles, you would need to implement a Custom Map Type. My favorite example of that is the Liberty City Map.

Highlighting custom locations on map

I would like to do something like what is shown in the screenshot - http://themanyfacesof.com/wp-content/uploads/2010/03/map.png
I want to be able to highlight certain areas on a map using PHP as a server side technology and jQuery(preferable) on client side with some tooltip functionality. Is there anything available or any idea how this could be achieved with the complexity involved?
Completely client-side solution: http://jvectormap.owl-hollow.net/
Look into using Google Maps for this. You can overlay lines and polygons which effectively means you can do anything - for example Loughbrough University does this.
A good way to start is to
Log in to Google
Go to Google Maps, then to my maps and create a new map
Draw polygons and line using the tools provided
Right click and copy the link for Google Earth, visit this link but change the output to KML output=kml. KML is just like XML
You now have a file with the exported polygons and lines that you drew. You can then re-draw these onto a Google Map programmatically
I did this the other day to get some rather complex polygons drawn onto a map without having to trial and error the latitude and longitude coordinates for them.
Hope that helps.
