ACTIVATING A PROJECT
In a database, the
graphical information is grouped by geographical areas, which is called a
project. In the "DF" database there is a single project
named "
As mentioned before a
project keeps data related to a geographical region. In order to have the
information captured from the earth surface represented in a plane, like the
computer screen or a paper sheet, we need to use a cartographic projection. The
cartographic projection used here is known as UTM/SAD69 which can be seen in
the Projection field. The SPRING documentation includes detailed information
about cartographic projections . Later you will have the opportunity to check other project
parameters as this one. At this point a window named "Control Panel" will be displayed. This window allows the user to select what data he/she wants to visualize. Two lists are highlighted Available IL’s and Selected IL’s. In the SPRING system the
same kind of information is grouped in categories. In this database
there are data of different categories, which will be described through these
steps. |
