Social Networking :: Calculate Distance From Latitude And Longitude In Google Maps V3
Jan 8, 2014
I have variable as
var from_Lati = 19.132324234 // from latitude
var from_longi = 19.11233334 // from longitude
and I have TO latitude and Longitude in Array as
var To_Lati = [18.132323,18.90941,18.31232423] // to latitude in array
var To_Longi = [18.2132123,18.242423,18.43243] // to longitude in array
I have gone through many reference on internet but can't find the solution for calculating the distance with respect to array.. Now I want to find the distance between them using JavaScript...
I want to caclate Latitude and Longitude from address in asp.net. I have written the necessary code ,but could not get the desired result
I have put an alert and tested it.Its working fine until geocoder.geocode()function is called.Alert put inside the function is not working.It seems there is some issue with function.
This is my javascript function
function calculateCoordinates() { var txtAddress1 = document.getElementById('<%= txtAddress1.ClientID%>'); var txtLatitude = document.getElementById('<%= txtLat.ClientID%'); var txtLongitude = document.getElementById('<%= txtLong.ClientID%>'); var address = txtAddress1.value;
I am working on a ASP.Net project(c#). I have SQL Server Database linked with it. The project has the list of client present in the city. A page will show the list of client on a datagrid . Clicking on a client will redirect to another page which show the details of that client. I want to display Google map picture or Google street picture of that client along with the details on that client details page through Longitude and latitude. Each client details will be fetched from the database to show on that page and every client longitude and latitude value is also saved in a column in the database.
This is code for searching latitude and longitude . so how to save into database.
function GetLocation() { var geocoder = new google.maps.Geocoder(); var address = document.getElementById("txtAddress").value; geocoder.geocode({ 'address': address }, function (results, status) { if (status == google.maps.GeocoderStatus.OK) { var latitude = results[0].geometry.location.lat();
I want to create a google maps that it can Calculate Distance, Travel Duration, draw (plot) Route between two locations and display Directions. Now I want to hide Directions Panel.
I used a Google Maps Distance Finder API that comes with two textboxes, one for the source, and one for the destination. It also comes with a button, that when clicked, will find the distance between the two locations using the funciton GetDistance(). The code before the function initializes the map. I created another button and used VB.Net to run SQL code first, and then to automatically populate the two textboxes, then I had it call the function GetDistance().
The issue I ran into is that the function won't calculate the distance, and the map never changes from its default state. I believe it's because it's not running the code that initializes the map. (I could be wrong) I have tried WebBrowser1, to call the click of the button, but I had to Inherit Forms, which I can't do, and I have also tried adding the top code into the GetDistance() function. Is it possible to call the initializing code before GetDistance()?
Here is the JS function code:
<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false&libraries=places"></script> <script type="text/javascript"> var source, destination; var directionsDisplay; var directionsService = new google.maps.DirectionsService(); google.maps.event.addDomListener(window, 'load', function () {

Here is the VB Code I use to call the JS Function:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click Dim cn As New OleDb.OleDbConnection("Provider = Microsoft.ACE.OleDb.12.0;" & _ "Data Source=|DataDirectory|Address Database One Calculation.mdb") cn.Open() Dim cmd1 As OleDb.OleDbCommand Dim sqlconnection1 As String

I have Postcode in my large database, which contains values like SL5 9JH, LU1 3TQ etc. Now when I am pasting above postcode to maps.google.com it's pointing to a perfect location.. My requirement is like I want to pass post codes to maps.google.com and it should return a related latitude and longitude of that pointed location, that I want to store in my database. So, most probably there should be some javascript for that If anybody have another idea regarding that please provide it
I am getting location by latitude and longitude from geolocation but location is not showing, If I pass latitude and longitude manually than its working good where is error in my code plz check my code.
Following the series of question, this is the code as of now has been developed and working fine. Now need to make some more tweek with this
1. Instead of distance from source to destination in KM can we have it in Miles
2. I need to show the distance between source and destinace only if destination falls under 25 mile radius from source else need to show the label message that no record found.
Here is the code
