I used Google Map v2 in my app. When I am trying zoom street, the map becomes blur and not clear. I look related questions on stack overflow but I can not find solution. Sorry for my bad english . Thank you

I have been trying for some weeks to come up with a price map. My inspiration is the heatmap found on the website of Housing.com . The link to the map is:
https://housing.com/dsl/heatmaps/mumbai/buy
I have tried:
Google maps Javascript API 3
heatmap,js library
and many other websites.
The resulting map that I am getting is visually less appealing.
Have they defined boundaries for very small regions and then introduced the gradient(which, again I am unaware how to implement.)
Any thoughts on how it might have been implemented are welcomed.
They don't use Google Maps Heatmaps Layer in the application, or any other library for creating heatmaps. You can see that between the requests the webpage makes are images like this, this and also more for bigger zoom levels. They just render these images over custom styled google maps as tiles.
More on how to render custom tiles over google maps, check this part of docs. For more information how to style the map below the heatmap to look like in the example, check this parts of docs.
Creating tiles images to render over your google maps can be troublesome, there are some tools, like this one which should be able to help you, but is paid. I don't know of any free solutions, you can create it manually although it might take some time.
Hope this helps you to better understand the implementation techniques behind the referenced map.
I guess that Leaflet has a projection bug. I'm trying to display a image over the Leaflet map using the "ImageOverlay" layer, but it's not fit well such as in Google Maps. We have a Python script that generate temperature graphs using latitude and longitude coordinates as y and x axis. Does anyone know if there is any solution to this trouble?

I think you should post this as a Leaflet issue (https://github.com/Leaflet/Leaflet/issues) if you haven't already done so.
Also, it would be great if you could post a JSFiddle or similar with an example of the code you're using to spot any problems.
I'm pretty sure there's nothing wrong with Leaflet's projection code, but there might well be some issues with the ImageOverlay or how you're using it.
I have a large non-map image that I want to allow people to view on a browser at multiple zoom levels. I want to display the image in google maps API or openlayer so that people can zoom in/out and pan. I was hoping i could then add additional layers to overlay things of interest on the image. I am looking at MapTiler to chop the image up into tiles that can be generated at multiple zoom levels, but I'm getting very confused...
MapTiler wants to know about the spatial reference system (SRS) for georeferencing of my my image files, and well I don't know what I'm supposed to tell it ;) I have no georeference data - I just want it to generate tiles for my image, and then allow me to display that image in google maps or openlayer. In addition, openlayers seems very dependant on georeference data..
Am I looking at the wrong solution, or are there any pointers to getting this to work? Can OpenLayers be used to display a custom set of image tiles at multiple zoom levels without georefence data?
Found the answer. It is possible in both OpenLayers and Google maps to display a custom map, providing your own tiles for the map...
This google groups posting details how you can use MapTiler to generate non-georeferenced images, which can then be shown on a OpenLayers image.
In MapTiler, you need to choose rastor image and then ensure that you don't add any georeferencing data to the image with MapTiler.
If i get this right maybe google maps custom overlays will fit your needs?
Suppose I have a Google maps co-ordinate in one sublocality, is it possible to find surrounding sublocalities in, say a 5 mile radius?
My guess is we can probably zoom into that co-ord at a high zoom level, like 13 or 14,but can we capture the labels on the map around our co-ord? That would be fine for my purposes.
Has anyone attempted this, or is there a demo lying around somewhere?
Google places webservice is the thing you are looking for.
http://code.google.com/apis/maps/documentation/places/
I've never tried this before, but this api should be what you are looking for: http://code.google.com/apis/maps/documentation/localsearch/
I have a little project with Google Map API: to show a small map on page. But the Google logo and copyright word are overlap together.
Can I move them out? And how?

You could do this fairly easily with CSS, but you'd break Google's Terms (see section 7.4).
If you can't make your window bigger, you could use an alternate mapping solution, like OpenLayers
