Here is a program recommended by us postal service which gives you, among other things, the latitude, longitude time zone and elevation for all us zip codes
The program is for $150 per year subscription but there is a 30 day money back period.
Hope this is ok. Let me know if you have any questions, and thank you for clicking Accept if you are satisfied with the solution
where did you mention FREE in your question?
So you want to be able to downloaded the data to your computer for free?
Actually, no, but only if there is no other choice... I am deveoping an algorithm that requires the user to select their elevation from a drop down menu.... I want the user to be able to input their ZIP and get their elevation (which is actually the average elevation of the entire ZIP area.....
Hosting this large database will demand bandwidth and disk space, which I do not want to sacrifice....
The online website should be free to the user....
I suggest that you buy the database so you will have it saved on your computer say as an Excel spreadsheet. We will then set up formulas and drop down lists that pull the elevation for the selected zip code.
If you want my assistance in setting it up after you buy the database let me know. Otherwise I am out of here
You do not need to pay for my advice. Not a problem, I'll opt out
