Form Google Maps URL that searches for a specific places near specific coordinates

You can use the query parameter ll for your lat and long, and you can use the query parameter q for what you want to search.

http://maps.google.com/?ll=39.774769,-74.86084

Or you can

http://maps.google.com/?q=your+query

Yeah, I had the same question for a long time and I found the perfect one. Here are some parameters from it.

https://maps.google.com/?parameter=value

q=

Used to specify the search query in Google maps search.
eg :

https://maps.google.com/?q=newyork or
https://maps.google.com/?q=51.03841,-114.01679

near=

Used to specify the location instead of putting it into q. Also has the added effect of allowing you to increase the AddressDetails Accuracy value by being more precise. Mostly only useful if q is a business or suchlike.

z=

Zoom level. Can be set 19 normally, but in certain cases can go up to 23.

ll=

Latitude and longitude of the map centre point. Must be in that order. Requires decimal format. Interestingly, you can use this without q, in which case it doesn’t show a marker.

sll=

Similar to ll, only this sets the lat/long of the centre point for a business search. Requires the same input criteria as ll.

t=

Sets the kind of map shown. Can be set to:

m – normal  map
k – satellite
h – hybrid
p – terrain

saddr=

Sets the starting point for directions searches. You can also add text into this in brackets to bold it in the directions sidebar.

daddr=

Sets the end point for directions searches, and again will bold any text added in brackets.You can also add "+to:" which will set via points. These can be added multiple times.

via=

Allows you to insert via points in directions. Must be in CSV format. For example, via=1,5 addresses 1 and 5 will be via points without entries in the sidebar. The start point (which is set as 0), and 2, 3 and 4 will all show full addresses.

doflg=

Changes the units used to measure distance (will default to the standard unit in country of origin). Change to ptk for metric or ptm for imperial.

msa=

Does stuff with My Maps. Set to 0 show defined My Maps, b to turn the My Maps sidebar on, 1 to show the My Maps tab on its own, or 2 to go to the new My Map creator form.

additional info:

http://maps.google.com/maps?q=loc: put in latitude and longitude after, example:

http://maps.google.com/maps?q=loc:51.03841,-114.01679

this will show pointer on map, but will suppress geocoding of the address, best for a location without an address, or for a location where google maps shows the incorrect address.
