Comments

  1. These are undoubtedly the best examples I have come across. Simple and easy to understand. I have found them most helpful. I would be eternally grateful if you could post an example that finds the user's current location and then calculates the route with directions to a fixed location. Thank you and keep up the great work!

Is Google cheating?

               I found this piece of interesting fact, accidently while browsing the internet. Google shows different maps for India, China and USA. Confused hun! Well don’t be…Just read on… In Indian version of Google Maps, you can see Arunachal Pradesh and eastern part of Jammu and Kashmir as integral part of India. In US version of Google Maps, you can see Arunachal Pradesh and Jammu and Kashmir as a disputed region. In the Chinese version of the Google Maps, you can see Arunachal Pradesh and JnK as not a part of India.                 Many people complained this issue to Google. A Google employee responded : “ We do show different versions of this border, because we required to by law. Indian law requires us to show it one way, and the Chinese law requires us to show it another way . If we can legally do so, we strive to present borders in a neutral and objective manner, which is why the US version avoids taking either side and simply labels the border as disputed. ”

Map Loading...

    The blank web page seems so boring and dull when the map is still loading. You will come across such a situation quite often where you will be having a slow internet connection! We cannot do anything about the slow internet connection, but we can surely avoid the dull blank web-page by using a simple trick. We can place a "loading" image at the center of the web page so that the page doesn't look blank! An image like this:             The following code will show you how this can be done and here it is!     As you all can see the code is very very simple and the output will look as seen in the results section above. The image below shows the loading stage of the map.       Do let me know what you think about the examples shared here! Do leave your comments here! Till the next example, happy mapping!

GIS Technology to identify all properties in BBMP Limits

          The Bruhat Bangalore Mahanagara Palike (BBMP) has for the last two years, been in the process of conducting a massive exercise to map the 13.87 lakh properties in the 198 wards in the city. Geographical Information System (GIS) has proven to be an effective tool for analysing and displaying thematic maps of all the roads for proper evaluation and correction of zones.            As of now, 11 lakh properties have come under the tax net. The aim of this programme, which is perhaps the first such exercise being conducted in the country on such a large scale, covering 800 square km, is to bring all properties under the tax net and ensure that the BBMP has accurate information pertaining to the properties’ dimension, built-up area, land use and classification. The process of validation of GIS maps will be completed in January 2011.           The process uses satellite digital maps of the BBMP area to generate a vector map from the information obtained. These high r

Retriving co-ordinates...

         We have seen 2 Google Maps API v3 examples wherein we have retrieved the latitude-longitude co-ordinates of the point of click on the map. In the first example we have displayed the co-ordinates in the information window and in the second , we have displayed the co-ordinates in a form in the information window.         Today we will create a code to retrieve the latitude longitude co-ordinates in a text box while simultaneously a marker appears on the map as well. So, here goes the code. <html> <head> <title> Google Maps API v3 - Adding marker on Click and retrieving the co-ordinates in a text box </title> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var map;    //When using event as a parameter to a function declare map, strictly as a global variable function initialize() {     var myLatlng = new google.maps.L
