geocoding

问题 I am using http://ubilabs.github.com/geocomplete/ to have a form submit latitude & longitude. If I just do the trigger below it works and fills up lat & lng fields. However, when I add the submit jquery code, it submits blank fields. I know its some timing thing since I can see the fields fill up but not sent via POST. But I can't figure it out, any suggestions? <script> $(document).ready(function(){ // Area for any jQuery $("#geocomplete").geocomplete({ details: "form", types: ["geocode",

问题 I am attempting to geocode addresses in R using the geocode() function in the ggmap package. I have done this on my personal computer relatively easily and want to attempt this on my work computer. Generally, I am supposed to register with Google, library the ggmap package, read-in my security key, and then I can use the geocode() function. But I get errors. See below: # Library package library(ggmap) # Set key file gmAPI <- "key_file.txt" # Read-in Google API key gmAPIKey <- readLines(gmAPI)

问题 I'm planning to use the Google Maps V3 API to geocode a batch of address stored in an array. These address will be retrieved from my database and geocoded so I can create markers for them on the map. However I understand that Google has placed a limit on the rate of geocoding requests sent to them, so I am wondering how I can use PHP to limit the rate of geocoding requests , to maybe 1 geocode every 10 seconds? sleep(10); ? 回答1: Yep, sleep(10) would do that. Alternatively, run the geocoding

问题 I am writting an application which needs to find the current location. The code is returning lattitude and longitude correctly but doesnt return the real address(reverse geocoding) what could be problem. Someone please help, i am new to android. I am testing on emulator with android 4.0 updateWithNewLocation() is called from onLocationChanged(Location loc) method void updateWithNewLocation(Location location) { if (location != null) { double lat = 29.00;//location.getLatitude(); double lng =

问题 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

问题 Assume this structure of a Geo::Coder::Google data dump --- dd $location; . address_components => [ { long_name => "Blackheath Avenue", short_name => "Blackheath Ave", types => ["route"], }, { long_name => "Greater London", short_name => "Gt Lon", types => ["administrative_area_level_2", "political"], }, { long_name => "United Kingdom", short_name => "GB", types => ["country", "political"], }, { long_name => "SE10 8XJ", short_name => "SE10 8XJ", types => ["postal_code"], }, { long_name =>

问题 I want to display midway in a google map. I followed this url : https://developers.google.com/maps/documentation/javascript/examples/directions-waypoints. Where I did make mistake that map didn't show multi-midway. When I used this method status is not ok HTML <input id="start" type="hidden" value="25.687158,32.639656" name="start"> <input id="end" type="hidden" value="24.088931,32.899795" name="end"> <input class="midway" type="hidden" value="27.300000,32.550000" name="midpioints[]"> <input

问题 I have to Geo Code 1000s of addresses to obtain Lats and Longs so that I can later run some data and geo analysis on those addresses. In the past, I used Google's API to obtain this information, however, now Google requires Credit card information to generate API key. Even then it has limit of about 60 address per hour or per day (can't remember exact limit). I was wondering if someone can guide me how to go about obtaining Lat and Long for 1000s of address with python? 回答1: SmartyStreets has

问题 I see two formats being used like: 41.45063 N and (N 40°48'27.34"). I assume: If i use first format then i need only 2 colums: Decimal, Direction If i use the second format then i need 4 colums: Degree, Minute, Second, Direction Which format is used to store in the database and how to convert from 1 format to the other. Also are we storing only the cordinates or even the direction like N,S,E,W? I am using cordinates for local places in MySQL. 回答1: You can convert the second format into the

问题 I have an app that needs to convert many addresses to CLPlacemark to get the latitude/longitude. In the Apple documentation it's explained that we should not perform many GeoCode request, Geocoding requests are rate limited. In my App, to perform the Geocoding I just request one Address and when I get the answer I will request the next one, until I have received the lat/long for all my addresses. I will put this code in a dedicated thread to not block the user. It seems to work but is it a
