Figure 2 shows two-dimensional (geog. latitude-longitude) sliced maps of equivalent vertical TEC and two-dimensional (latitude-altitude) reconstructed electron density images.
The model covers the near Earth space between 200 and 40,000 km altitude and outputs debris distributions in one-dimensional (altitude), two-dimensional (altitude, latitude), and three-dimensional (altitude, latitude, longitude) formats.
A map projection transforms the Earth's spherical two-dimensional coordinate system called latitude and longitude to the plane or planimetric map surface.
Summing the number of records for each unique combination of bottom depth and sample depth results in a working dataset of 6987676 individual records sampled from 172012 unique locations in three-dimensional (latitude, longitude, sample depth) space.
So Richardson broke Germany down into a series of two-dimensional boxes, each measuring three degrees of latitude by three degrees of longitude.
Finally, we used thin-plate splines, a two-dimensional extension of regression splines, to model longitude and latitude and capture additional spatial variability unaccounted for after including our deterministic spatial predictors in the model.
Finally, we used thin-plate splines, a two-dimensional extension of nonparametric regression terms, to model longitude and latitude and capture additional spatial variability unaccounted for after including our deterministic spatial predictors in the model.
It recommended using geometric lines of latitude and longitude to convey a three-dimensional Earth on a two-dimensional surface, and it included the co-ordinates of over 8,000 locations in the ancient world.
Fig. 3 Two-dimensional structure of electron density on altitude latitude and latitude longitude planes.
Figure 3 shows the two-dimensional electron density results of GPS tomography on altitude latitude plane at 136°E longitude (Fig. 3a c) and latitude longitude plane at 300 km altitude (Fig. 3d f), respectively.
Furthermore, the stop-and-go flow scheme was applied in the 1st dimensional CCC to fit with the time constraints of the 2nd dimensional preparative HPLC.
