Our pojata : geographical data : Google Earth is a wonderful piece of software: not only that the aerial views of the Earth surface are with a resolution of ten meters or better (some highly populated areas with one meter resolution) but, as you glide the pointer over the chart, the software displays longitude, latitude and elevation at the pointer position. Longitudes and latitudes are posted with a hundredths of a second precision, elevations in one foot increments.

The longitude and latitude precision seems unusually high; is it justified? The mean Earth circumference is 40,007.86 km; it follows that the distance on Earth surface corresponding to 0.01" amounts to 40,007,860/(360*60*60*100) = 0.3087 m. How nice: 1 ft = 0.3048 m, i.e. longitudes and latitudes are given with the same precision as elevations.

Nevertheless, it might be a problem with the elevation numbers. Google Earth gives for our pojata an elevation of 151 ft, which looks reasonable. However, when pointer follows Grabov Rat sea water front line, Google Earth gives elevations of 90 to 100 ft; one has to point quite off-shore, probably around 50 meters, to record elevation zero. The non-zero elevations at the shore canít be attributed to the tidal variations: Mediterranean Basin has no tides of that magnitude.
