Can i search for the landmarks like Hotels,Cinemas,etc from the latitude and longitude using geocoder? If yes.how?

Where are the lat and long in this gps string?

Can anyone tell which are the latitude and longitude in this gps tracking string ?
*hq,35632708012xxxx,VP1,V,226,001,42020,28871,0Y42020,14583,30Y42020,28872,13#
Position should be in Romania if it helps.
Edit: it is from a chinese GPS tracker purchased from eBay, it looks like attached image.
The data string is what I got sent to my server.
It works crappy, for example if I send command "GOOGLE" should returna google link but it returns a text advertisement in Chinese that contains something like "free shipping" :/
From what I asked around the protocol is similar to "H02", but it looks like I am missing some "N"/"S" between the numbers that should be the lat/long positon, so I am confused.

Geomapping using Qlikview BI tool

I have a dataset with country names (to and from) which is similar to travel starting country and the destination country.
For example: if the travel is between India to Australia then the country origin will be India and the destination will be Australia.
I have collected the latitude and longitude for both origin and destination place.
Now I want to plot the lat and log for origin and destination country using Qlikview tool.
I'm using Qlikview11 Personal edition.
Two ways to achieve this case:
1. Using GeoQlik extension
Install GeoQlik extension in Qlikview Click to Install GeoQlik
Open GeoQlik extension in Webmode and choose Line Graph.
Add the dimensions as Country Origin and Country Destination
Add the lat and log positions as in below image.
Similarly you can do it for Country Destination.
You can also adjust the line width and color properties also.
Demerit: In GeoQlik trial version, you cant able to save the visualizations.(need to be licensed version to enjoy all the features)
2. Using Line Graph
Ref from : http://qvdesign.wordpress.com/2012/06/22/new-qlikview-chart-type-dynamic-network-flow-charts/
They used static image of world map as background. They created a line graph with X and Y coordinates running axes from 0 to 200 and set as transparent.
Here the fuzzy thing is I don't know how they calculated lat and long positions!
You can use the Qlikview Mapping Extension that installs with the product. See the "Extension Examples.qvw" in the installed examples. Note the instruction on the first sheet that directs you to complete the installation by launching the .qar file. In the Extension Examples is a sample showing how to plot lines and points on a map.

How to get city by latitude and longtitude?

I need to get city name by latitude and longtitude. (Use xcode)
There is google with itself's api geocode, but it don't want to return nearest city (i need only nearest city) and it returns cyrilic names of places. How to solve my problem?
You could use the Geonames.org webservice for "Find nearby populated place / reverse geocoding" (scroll a bit down), see this example.

Rails Geocoder Function

With the geocoder gem, if I wanted to find pictures nearby one particular picture by a mile I could do pictures.nearby(1) but what if I had a user with a location and wanted to find pictures nearby my user, how would I do that
Instead of nearby() you can use
Pictures.near([u.lat, u.lon], 1) # venues within 1 miles of a user
See GitHub/geocoder

Program a webpage that returns Lat and Long from Google Map when an address is entered?

I've looked at
http://code.google.com/apis/maps/documentation/staticmaps/#Locations
But it doesn't show how Google Map would return Lat and Long when an Address is entered.
Check out the "geocoding" and "reverse geocoding" sections
http://code.google.com/apis/maps/documentation/geocoding
A sample page that does what you're describing:
