Determining longitude is incredibly difficult--for humans. Are animals fooling us into thinking that they have bicoordinate maps? New experiments show that at least some creatures effortlessly solve the seemingly insoluble problem of longitude.

An analysis of 10 years of campaign Global Positioning System (GPS) data collected in periodic surveys of the Basin and Range shows that vertical velocity measurement is less precise than horizontal measurements by approximately a factor of 3, and less precise than velocities from continuous GPS sites by a factor of 3-4. To obtain this level of precision, a method for conservatively quantifying...

Geocoding, the process of matching addresses to geographic coordinates, is a necessary first step when using geographical information systems (GIS) technology. However, different geocoding methodologies can result in different geographic coordinates. The objective of this study was to compare the positional (i.e. longitude/latitude) difference between two common geocoding methods, i.e. ArcGIS (...

We report simultaneous H110α and H 2 CO line observations with the NRAO Green Bank Telescope toward 72 H II regions in the SPITZER/GLIMPSE survey area (|l| = 10 • − 65 • and |b| ≤ 1 •). We used the H110α line to establish the velocity of the H II regions and H 2 CO absorption lines to distinguish between near and far distances. Accurate distances are crucial for the determination of physical pr...
