I have a spreadsheet of data from a lake that was scanned. There are 3 columns, Latitude, Longitude, depth. I would like to pull this information the spreadsheet or database and have it build the lake. There are thousands of points to build the lake bottom.

I've looked up different ways but can't pinpoint something that will work. Java, PHP, AJAX, what would actually work. Java is what I was aiming for but I'm second guessing that after researching. I am stuck.

Please Help!!!
