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).
