Job Description

I require a simple utility (Windows 7 desktop) that can take a file containing comma separated values of LAT and LONG and determine which values fall within a specified U.S. zip code. This file can contain up to 15M entries.

Input (3 inputs):
1. Name of lat/long file. File is .csv or .txt file with two entries per row - lat and long. These entries are separated by a comma (i.e. 38.602249, -90.437665)
2. U.S. zip code
3. Name of output file.

Output (1 output):
1. Output file. This file will have a single column of lat/long coordinates that were found within the specified zip code.

Example:
1. Let’s say the input file has the following values:
32.338322,-95.290657
38.620827,-90.446241
32.725671,-96.638339
33.795749,-117.914236
38.602249,-90.437665
40.896655,-74.239174
27.418157,-80.386683

2. The user inputs “63161” as the zip code.

3. The resultant output value would contain the following two coordinates:
38.602249,-90.437665
38.620827,-90.446241

Implementation: This application will need to examine each lat/long entry in the input file and determine if it falls within the zip code. I assume this will require some type of web services call to a GPS database on the internet.
