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

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 have a large high-resolution image that I am using for an overlay using Google Maps v3 API. This works fine for desktop and laptop computers with a reasonable network connection, but unsurprisingly it does not work so well for mobile users.
What's the best/easiest way to break the image up into 2D tiles at the various zoom levels so I can act as a tile server for Google Maps via the API?
Is there a program that will reliably generate the tiles for me and provide me with the necessary zoom and coordinates for each resulting tile and/or give me the correct tile if I provide the zoom and coordinates?
Is it pretty easy to write a tile server to do it on the fly once you gather the right info? Perhaps there's source code out there that I can use as a model? (I found a tile server at http://blog.gmapify.fr/a-map-tile-server-part-2-understanding-google-maps-tile-overlays-and-building-up-a-tile-server which is certainly helpful, but it doesn't serve tiles from a source image, so I'd have to at least figure that part out...)
Or perhaps there is step-by-step algorithm that I can manually follow if that's more straightforward? (Since it's only one image and it covers an area on the map of maybe a square mile, manually doing it like that is perhaps feasible if not preferable.)
you can check MapTiler http://code.google.com/p/maptiler/. It can generate the tiles you need.
Tile server is really easy to write. The easiest way is just to host static files (your tiles) in a directory structure. The directory structure is then usually servername/zoom/x/y.png (or zoom/y/x.png). Such structure is also produced by MapTiler. MapTiler also generates an example web page using the tiles (but I guess it uses Google Maps API v2).
Information about using your tiles in Google Maps API v3 can be found here: http://code.google.com/apis/maps/documentation/javascript/maptypes.html#CustomMapTypese
You can do the entire thing clientside without tile pre-cutting
See https://github.com/Murtnowski/GMap-JSlicer
slicer = new JSlicer(document.getElementById('map'), 'myImage.png');
slicer.init();
Very simple.
There's a really good video tutorial on making maps with maptiler, which can be found here:
Mobile Maps That Aren't Terrible
It focuses on mobile maps, but also covers maptiler and other basics. I found that very helpful.
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?
How much control do I have regarding the styling of a google map?
Can I make it more closely resemble a site's colour scheme or are we stuck with pastels?
Controls
There is a decent description of the process to override the set of builtin Controls. So you have total control over the UI elements overlaying the map.
Map Tiles
I don't agree with the previous answers that you are out of luck if you want to change the images in the map itself.
The range of map types available give you a few options outside the pastel default map:
G_NORMAL_MAP, G_SATELLITE_MAP, G_HYBRID_MAP, G_PHYSICAL_MAP, G_MAPMAKER_NORMAL_MAP,
G_MAPMAKER_HYBRID_MAP, G_SATELLITE_3D_MAP, G_DEFAULT_MAP_TYPES, G_MAPMAKER_MAP_TYPES
Obviously, this only works if you are willing to create the tiles, but Custom Tilesets are quite well supported by the Google Maps API and there a few good examples out there:
World of Warcraft tileset
Batmud tileset
Tower of the Hand tilset
Update
Google recently announced support for Styled Maps in the Google Maps API. You can extensively customize the color scheme used by Google Maps. So you can customize the look of your mashup, without resorting to custom tilesets.
You can probably change around all the controls, perhaps by making your own or subclassing the google default versions. You won't be able to change the colors on the map itself without generating all new map images, at which point you are probably better off using something other than google. If thats what you want, you should consider OpenStreetMaps.
I've looked into this before. From what I've found is that the styles of layers/overlays on the map are pretty much determined by Google (minus a few size option for some overlays). What I have found is that you'll either need to subclass the existing overlays or create entirely new overlays that mimic the existing functionality, which in some cases can be painful given their complexity (such as street view and others).
Last I checked, you were stuck with the colors you were given (this was a year ago). You can check http://code.google.com/apis/maps/ for more info.
I have large images that I would like to have dragging and zooming controls like Google Maps. I started looking into Google Maps API and some other related websites, but I could not find something simple and easy.
MapKi tutorial suggests me to automatically cut tiles and add it as a custom map. This makes sense, but I have so many images in the file server that I don't have time to go through all of them and cut the tiles and figure out zoom levels for each. One good solution would be writing a script that can do this automatically, but that would take a lot of effort and time that has made to look for another solution if there is any.
Hence, is there a way to have similar functionalities as Google Maps controls for images without creating new images or tiles out of the original image. It would be great if you can either post some code or link to the tutorial/documentation. Or, if you know how to do this with Google API without making those tiles, please direct me to the right path. I'm a total newbie with Google Maps API.
I have found the DragZoom for Google Maps, but I don't think that's what I'm looking for.
You're looking for something like Djatoka
You should take a look at the IIIF protocol used by libraries and museums for zooming extremely large images (tens of thousands of pixels on a side +), preparing collections of images on canvases, presenting annotations on those images, etc.

…and just for the record here's an open source tiling server with a frontend viewer:
http://iipimage.sourceforge.net/
Check out https://github.com/Murtnowski/GMap-JSlicer
slicer = new JSlicer(document.getElementById('map'), 'myImage.png');
slicer.init();
It's super simple, no need for tile pre-cutting. Just point at a single image and go.
