latitude-longitude

问题 I am developing wpf application. I have one static world map of 500 width and 500 height. I have one form in my application. In this from user enters the latitude and longitude and submit the details. I want to show the exact location of these latitude and longitude on my static map. So I am trying to convert these latitude and longitude into pixels. I am using ellipse to show the circle on my static map. How should I convert the geographical coordinates into pixels in C# ? Can you please

问题 I only want to display a google map of a specific area on the mobile screen. The map should not move beyond that area when there is user interaction such as zoom or moving the map. For example: These are latitude and longitude bound: LatLng one = new LatLng(42.0140555,-88.2131937); LatLng two = new LatLng(40.993729,-87.6622417); 回答1: I have found the solution this way. Do this on onMapReady() function. @Override public void onMapReady(GoogleMap googleMap) { mMap = googleMap; //get latlong for

问题 I am trying to substitute values in a data frame from values in another data frame based on a condition. Both data contain latitude, longitude and height but one of them is shorter. I want to pick any point from the shorter data frame (5103 rows) , find the closest values on latitude and longitude (by calculating distance) on the second one (188426 rows) and then replace the height value on the longest data frame with the height on the shorter one. The first data frame is topo.rams in the

问题 I want to get city name from longitude and latitude. I am using following code but it is returning the entire address with city name, postal code, province and country. I just want only city name. $.ajax({ url:'http://maps.googleapis.com/maps/api/geocode/json?latlng='+position.coords.latitude+','+position.coords.longitude+'&sensor=true', success: function(data){ alert(data.results[4].formatted_address); } }); Please see the result from geocoding { "long_name" : "Vancouver", "short_name" :

问题 I am getting coordinates - lat/lon and I want to check if these coordinates are in the continental United States or not. Is there a easy way to do it in C#? I can convert the coordinates into MGRS or UTM. Thanks! 回答1: Oh wow, they have it just for you: http://econym.org.uk/gmap/states.xml All the coords of the US states! Build up a polygon and apply any polygon-contains-point algorithm. The classic algorithm is ray-casting, and its even pretty simple. Let me know if you have any trouble with

问题 I have 1100 station location (latitude and longitude) data and 10000 house location (latitude and longitude) data. Is it possible to calculate the lowest distance between station and house for each house by using R codes? I also want the station that gives the lowest distance for each house. Is it possible? 回答1: Here's a toy example for finding mass distances between m points and n cities. It should translate directly to your station/house problem. I brought up worldcities, spun the globe (so
