Any unauthorized user can crop any of the regions of or any data in a
vector map. We crop a region occupying an area of approximately from 10% to 90% of the vertices that are randomly selected in the polylines.
A precisely coded
vector map is ready for entering almost infinite data quantities.
Further analysis of the wind
vector maps disclosed new evidence that the inverse energy cascade process supplies the energy that forms and sustains Jupiter's numerous jet streams.
Vector map data reduction can be done by generalization of the spatial data.
Before every picture (three for each of my 15 experiments), we moved the reflector into the desired position, then ensured that the laser sheets were wide and intense enough for the PIV system to detect the necessary amount of smoke particles to produce a coherent velocity
vector map. The width of the laser sheet was important, too, because if it was too wide, the light intensity would be too low; if the sheet was too narrow, many pictures would have to be taken inside the model.
The results from trend surface analysis are summarized in a velocity
vector map (Figure 9).
A feature is the
vector map's representation of an object.
Whereas the previous section discussed tools for a table, this section will discuss tools for a
vector map. Spatial analysis means analyzing space; therefore, it makes sense that we have several tools for maps.
This includes optional superimposition of the
vector map data over the photographic image for better quality control and for map revision applications.
Therefore, all we need for this factor is a line
vector map that represents the ponds, streams, creeks, or waterways.
