geocoding

How can I check if a geopoint is within the area of a given shapefile? I managed to load a shapefile in python, but can't get any further. Richard This is an adaptation of yosukesabai's answer. I wanted to ensure that the point I was searching for was in the same projection system as the shapefile, so I've added code for that. I couldn't understand why he was doing a contains test on ply = feat_in.GetGeometryRef() (in my testing things seemed to work just as well without it), so I removed that. I've also improved the commenting to better explain what's going on (as I understand it). #!/usr/bin

I am trying to see whether the user is within a certain distance of an address. I have successfully managed to get the users location, and convert the address with forward geocoding. I am left with two sets of coordinates. I am trying to make an if statement saying if they are within "a distance", print something! Currently when i print the coordinates inside the placemark function i get the desired coordinates. When i call them to create eventLatitude and eventLongitude they become 0.0. I know this is a ascycronous problem, but i am unsure on who to resolve this. Can someone give me an

I'm attempting to use ggplot2 and maps to plot the names of the counties in NY state. My approach was to find the means of latitude and longitude by county (I assume this is the center of the county but this may be faulty thinking) and then use geom_text to plot the names on the map. It's not behaving as I anticipated as it's plotting multiple names per county. The outcome I'm looking for is that the center of each text (county) is at the center of it's respective county. In addition to solving the problem I'd appreciate helping to understand what's wrong with my thinking with ggplot. Thank

If i have a jpeg map with size sizeX, sizeY and some calibration points on the map (X, Y, Lon, Lat) What would be the algorithm for calculating the corresponding XY point in the map with a given Longitude / Latitude pair? Here's what worked for me, without so much bs. int x = (int) ((MAP_WIDTH/360.0) * (180 + lon)); int y = (int) ((MAP_HEIGHT/180.0) * (90 - lat)); The lat,lon coordinates were given to me by Android devices. So they should be in the same standard used by all Google Earth/Map products. If using the Equidistant Cylindrical Projection type map , here is what you need to do: Find

I have a textbox in my page which gets a location name and button with text getLat&Long . Now on clicking my button I have to show an alert of latitude and longitude of the location in the textbox. Any suggestion? You can use the Google Geocoder service in the Google Maps API to convert from your location name to a latitude and longitude. So you need some code like: var geocoder = new google.maps.Geocoder(); var address = document.getElementById("address").value; geocoder.geocode( { 'address': address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { // do something

Our site has the option to insert your postcode in, which in turn works with geocoding to work out the latitude and longitude. This code has not been changed for years but today if the user trys to insert a postcode or update it from yesterday or before the error 'The remote server returned an error: (403) Forbidden.' pops up. The requests have not shot past 2,500 so I cant see Google blocking us because of that.. Any ideas?? The version 2 Geocoding API was turned off September 9th as announced... From Upgrading Your Geocoding API Application To v3 Version 2 ("v2") of the Geocoding API was
