Add an INSROP theme to a view document
To add a theme from the INSROP GIS database into a view, choose Add INSROP Theme in the View menu. This will initiate the following actions:
1. Get the thematic list of INSROP GIS data sets
2. Select a topic from which to add an INSROP GIS data set
3. Get the list of INSROP GIS data sets within the selected topic
4. Select an INSROP GIS data set within this topic
5. Get the definition file associated with the selected data set
6. Select one or several data themes within the selected INSROP GIS data sets
7. Set theme name and field name aliases
These steps are described in more detail in the following:
Get the thematic list of INSROP GIS data sets
The thematic list of INSROP GIS data sets is read from the overall dataset
definition file, datasets.def.
Select a topic from which to add an INSROP GIS data set
Based on the information acquired in Step 1, the user is presented a list of
data set topics, from which one topic may be selected. If you want to use data
sets from another location than the one defined for INSROP GIS, you must choose
<Other datasets>. You are the prompted to select a definition file (*.def).
This may be a data set definition file, in which case your next step is Step 6.
However, you may also choose to organise your alternative database(s) similar to
the INSROP GIS database, in which case you should select the proper datasets.def file at this step. Then you may use data sets (e.g. non-public ones) from
your own database in the same way you use data sets from the INSROP GIS database.
Get the list of INSROP GIS data sets within the selected topic
Based on the user's choice in Step 2, INSROP GIS goes to the proper database
sub-directory. This sub-directory comprises a topic dataset definition, which is read by INSROP GIS.
Select an INSROP GIS data set within this topic
Based on the information acquired in Step 3, the user is presented a list of
data sets, from which one data set may be selected.
Get the definition file associated with the selected data set
Based on the user's choice in Step 4, INSROP GIS goes to the proper data set
folder. This folder comprises a dataset member definition file, which is read by INSROP GIS.
Select one or several data themes within the selected INSROP GIS data sets
A data set may comprise one or several data set themes. INSROP GIS opens an
"Add Theme"-dialogue window, where the user may select one or more themes to add
to the view. This step is similar to the standard ArcView "Add Theme" menu
item. However, in addition to adding the selected themes, INSROP GIS gives the
themes the names defined in the dataset member definition file read in Step 5.
Set theme name and field name aliases
Since dBase tables only can store field names with max. 10 characters, INSROP
GIS includes a possibility to define field name aliases in Data set member attribute definition files (*.fld). When a *.fld file as defined in the Data set member definition files exists, filed name aliases are read from this file when the data sets are
added to the project. Also an alias name for the theme is set (instead of the
default one which is just the file name).
