| These paintings, like the GPS longitude, latitude, and time read-outs, simply mark the artist's presence. |
| To picture the difference, start with the way geographers mark longitude and latitude on Earth's surface. |
| Its goal is to visit each of the latitude and longitude integer degree intersections in the world, and to take pictures at each location. |
| Instead, as is shown on the map, most co-tidal lines lie at a marked angle to the longitudes and some are even perpendicular to them. |
| He returned with astronomically determined latitudes and longitudes for many of the places he had visited, essential data for accurate mapping. |
| They are primarily seen at 40 degrees south latitude, and they appear at many longitudes. |
