NETWORK_OBJECTS
A NETWORK_OBJECTS file type is exclusively for the line identification and
nodes for network model maps in the SPRING. The first line in the file has the
keyword NETWORK_OBJECTS. This line starts the identification section, which is
a mandatory section. For this entity the information section is not mandatory, except
for the SEPARATOR item.
The data syntax in the NETWORK_OBJECTS file changes as a function of its
purpose, that is:
- Identify oriented lines in a network map - it is required to inform the
coordinates pair X/Y or Lat/Long, a label, a name (not mandatory), an object category
and the keyword LINES.
- Identify a network node - it is required to inform the coordinates pair
X/Y or Lat/Long, a label, a name(not mandatory), an object category and the
keyword NODES.
Still, in the data section it is possible to use different formats:
- Define a separator character ( ; or , ) between data through the keyword
SEPARATOR
- Use the keywords; LABEL, NAME, CATEGORY_OBJ, LINES or NODES:
- LABEL: identify oriented lines or nodes through a label (unique) associated
to an object category, from a network map. Each entity can have one or several labels,
but they have to have different coding (see more about object identification in
chapter 9);
- NAME: indicates a network entity name, it can have repeated names for different
labels. If the name is missing the system replicates the label as a name while importing;
- CATEGORY_OBJ: it is an identifier of the object category, when an entity is
represented in a cadastral map.
- LINES: network lines identifier.
- NODES: network nodes identifier.
The general format of the ASCII file for the NETWORK_OBJECTS entity is presented in the
example below.

NOTE: When exporting an IL from the network model, the option Lines and Identif.
in the
" Exporting" window, the
NETWORK and NETWORK_OBJECTS files
are created. When exporting, by default, the file name extension is "spr", with
the "_NETOBJ" suffix added to the IL's name, that is, *_NETOBJ.spr. However, when
importing the file has to have only the "spr" extension, in case the file was created
in a different system.
