I found getTile.m worked well for nearmap images, but it didn't work with google images.

GUI-based program for tidal analysis and prediction using up to 35 tidal harmonic constituents.
Author: John Boon
A very slick application. Well developed. One problem with it though is that for analysis you can only read in *.xls files... This limits you to 65536 hourly records, which is not enough for proper tidal analysis (need ~19 years). Would be preferred if you could pull variables from the workspace, then you could perform the tidal analysis using a longer time series of data. Well put-together though, and very user-friendly.
