I have an application which uses geography informations.
I don't want to implement this feature because I think I could find a free services which provides needed informations to me.
Anybody can help me which service I could use?
(Geography information means country, county, town data.)
Try this:Google Maps API
The "Geocode" feature allows you to pass it any Address and it will figure out the Latitude/Longitude for you!
Then you can later use the Lat/Long to generate a Map with a Marker on that point.

I have a question regarding appropriate use of the GeoIP Location in Qualtrics as part of display logic.
I wish to restrict the display of one question only to participants from London, England. I have looked at the support page regarding this topic. However, there is no further help about what values are accepted in specific fields available in GeoIP location. I have simply typed in "London" (see image below); however, they could also require coordinates or other values.
Could you please advise how to set up the display logic with GeoIP Location only to London, England?
Is it possible to restrict the GeoIP even further only to certain London Burrough for example? Can you please provide an example?
Is it possible to restrict the GeoIP location to a polygon coordinates? For example, I will set up the polygon using map polygon tool. Is it possible then restrict the display logic only to GeoIPs only within the polygon? Can you please provide an example?
Thank you for any help.
I need to know in which country (and hopefully some more info, like city or area or state and it would be great if I could get whether this is on land or sea) a coordinates set lies in.
I have tried the wikimapia api but it is extremely difficult to get around to it.
for example I have this call
http://api.wikimapia.org/?function=box&key=example&bbox=23.72251,37.96918,23.73094,37.9731&format=json
which brings some information about an area in Athens, Greece.
The problem is that not only this api call is depreciated, but when i try to get the country by adding &category=2977
http://api.wikimapia.org/?function=box&key=example&bbox=23.72251,37.96918,23.73094,37.9731&format=json&category=1176
this doesnt work(the category id i got it from this gist)
I would guess that this might have something to do with the method being depreciated, but when I change to the new method place.getbyarea it is not working at all.
http://api.wikimapia.org/?function=place.getbyarea&key=example&bbox=23.72251,37.96918,23.73094,37.9731&format=json
Any ideas? thanks in advance
Why do you want specifically the API of Wikimapia to get your information? To recover the city and country from GPS coordinates, some others API’s are much more appropriate I think, here some examples:
Google Maps (used here in a webpage)
Here Maps
Bing Maps
Apple Maps (Mapkit.js)
Algolia Places
OpenStreetMap Nominatim
Is there a library or service that returns the US federal congressional district given a US address?
You can do this on govtrack.us. I am not sure if there is a code framework for this, but you could probably write one from this information.
Full disclosure - I work for a company that also provides congressional district data - smartystreets.com
Keep in mind that this information changes often and I have been looking for the last 4.5 years and haven't yet pinpointed an actual, absolutely reliable source for this data. All of the companies I have looked at, including mine, say that their source is the US Postal Service but no one in the US Postal Service has been willing to tell me how frequently the data is updated within their system and what their source might be. So, just be aware.
I'm one of the creators of Geocodio and we had this problem ourselves. So we made it part of our geolocation tools!
You can use the Geocodio API or spreadsheet upload to look up Congressional districts, Representative/Senator contact information, etc. Docs: https://www.geocod.io/docs/#congressional-districts
You can use the Sunlight Foundation Congress API, which is free to use. Go to: http://tryit.sunlightfoundation.com/congress You can determine congressional district by zipcode (not completely reliable since zipcodes can traverse multiple districts) or by latitude/longitude. Just use Google geocoding to retrieve lat/lng from your address, and then you can look up the congressional district.
The whoismyrepresentative.com/api site can translate a zipcode into a congressional district. You can do a call with the url below, replacing 10038 with your zipcode.
http://whoismyrepresentative.com/getall_mems.php?zip=10038&output=json
Hope that helps!
**Also note that the sunlightfoundation site returns a 404 error and govtrack.us does not have an api for searching for congressional districts.
Can I get the country information just from Latitude and Longitude of the user? I know it should be easy to get it from Geocoder APIs from Google. But is it possible to derive that information without using any services like Google's?
Could you please let me know?
The only way of doing this is by using a third party API or creating your own database, which is a lot more work that it's worth. Have you looked to see if there is a GeoIP database that you can download for your programming language of choice (Or a generic one?)
Edit: This looks like it might have the data you need
There are a lot of geocode services out there (like http://geo-autocomplete.googlecode.com/svn/trunk/demo/ui.demo.html for example) where user can write a location (or part of it) and it will be resolved to real existing location.
There is also a lot of info provided with the search result (like country ISO code, coordinates, etc..), but none of the services seem to provide country and city code.
What I mean is a code used to phone to certain are. For example Country code for Germany will be 49 and for city of Dusseldorf will be 211.
Is there any service, where I can get this info from the user input. Or is there any way to combine the two. For example I get city name from google geocode service and the try it on some city codes database. If yes, can anyone please provide me with links.
You can use for instance Yahoo's GeoPlanet. For more elaboration on services to solve your problem you might want to check out this answer on gis.stackexchange.com, which seems to cover the kind of service you need.
