Hello everyone,
I am developing a web-based application using
google maps API.Though I have some programming knowledge,I am new to
this.So, I am going through Google Maps API and Mike Williams
tutorial.My current webpage geocodes single address and points a
marker on the google map using Javascript and VB.NET.I have an excel
file (this file I get from some other location and has approx 10000
records) containing Names, Address,State, Zip and many other
fields.For the existing file, I would like to add two more fields, lat
and long.My main task is to geocode all these addresses and store the
lang and lat in the same file.I dont want to use batchgeocode:
http://www.batchgeocode.com.. because if the data in excel file gets
updated later..my aplication will not give inaccurate results.so I
would like to write a program in such a way that, when it reads the
file and checks for the field values
lat = "null" and long = "null", it should geocode only that
particular address for the first time..This way I dont have to geocode
entire file everytime I run the webpage.Once I have all the addresses
and their lang and lat's.I can format the data into an xml file and
mark the locations on google map.May be this question was asked many
times before but could not find proper answer to it.I appreciate any
kind of help.
