the problem is Math funcation here calculate the things in radian i want it in degree. so i just found a formula to convert radian into degree but that formula does'nt convert the calculation correctly..
what to do bcoz there is'nt any other option to convert radian into degree..
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 have array of lattitude and longitude which is derived from one type of polygon, now i want to find all latitude and longitude from my database which are inside this polygon.So how can i achive this?
how can i raise event just after user change his position in google map using dragging map and get the latitude and longitude of center of google map and the miles its showing from center. i have got lots of pages on google related to it.. but not able to solve this.. please give me solution (i am using asp.net and javascript)
I want to get latitude and longitude from address in one of my asp.net application, i know it s possible using google apis but i want to do it without showing google map. How can i do that? I also want to get distance between two pairs of latitude and longitude.
var txtlat=document.getElementById('TextBox1').value=GMap1.getCenter().lat(); var txtlong=document.getElementById('TextBox2').value=GMap1.getCenter().lng();
It gives a JavaScript error as "Object doesn't support this property or method". How can i do this?
I've been struggling for the past couple of days to get this right. I'm in the process of building something that takes a whole bunch of geographic points, builds a heat map from the data, then overlays it as a tile on Google Earth / Google Maps. A bit like this: [URL]
I have all the heatmap functionality nailed using random xy points. The last part is doing the actual conversion to convert my real lat/lng pairs into x/y pixels to be rendered onto the heatmap image. Lets say I the image is 500px x 500px. I know the min and max values for the lat/lng points, so technically I need to divide the spread between the pixels to get a pixel value for each degree based on the top left pixel of the image (0,0). I've been through so many examples, but I just cant get them to work. The last one I tried was this:
[Code]....
I feed data into my heatpoint function using these 2 functions above like this. Here's a set of 4 points:
[Code]....
The problem I get is that the result is the same for all the points - they all get plotted to exactly the same point. Now, the data is fairly localised, so I dont really need to take the curvature of the earth into consideration.
i am developing a travel application. for that I need to calculate the future local datetime of a location using Datetime (a future date),longitude and latitude. (for Eg: i want to calculate the local datetime of a location on August-10- 2010 11.23 AM . Due to the day light saving time the datetime offset may change so i need to convert the august-10- 2010 11.23 AM to local time of the location) I have the inputs longitude, latitude and Date time. i can calculate the current local date using Longitude and latitude but cannot calculate accurately for *future date because of the day light saving time off set* . off set may varies on future dates. i am using asp.net and c# .
I cant seem to find a good example of how to build the query logic. We are allowing users to search based on lat/long and need to add radius as another parameter. So you enter 29.30125 as the latitude and -95.04590 as the longitude and pick say 15miles as the radius, i need to return all records that fall within that radius.. can someone suggest a good site to review this type of query?
I have latitudes and longitues in a table but they are in a nvarchar(50) field althought the values are like this -> 39.7355 I need to be able to convert those values to numeric to execute a calculation and update a new field
How to Track the Vehicles using Virtual earth control based on longitude and latitude.Every 5 seconds longitude and latitude values are coming from the database.based on these values vehicle position has to be changed. How to do it. Please give me complete code for this.
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 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.
