In this model, each toolbox is an extension of ArcView GIS. They are different in using level and purpose. Users of DIGIS 1.0 interact with these toolboxes through a simple interface called Expending Function Interface. After activating needed toolboxes, users start to use functional menu bar, button bar, or tool bar for their various tasks in a familiar environment, an ArcView GIS environment.

The Core applications toolbox was expected for public uses. It has these characteristics:
- It can be used by both the district’s staffs and the citizens.
- It supports users to identify, query, and count up data.
- Included tools do not change any data in database. Users can retreive data from database rather than update data.
- Data to be retreived can be spatial or attribute data.
- Results produced by these tools are reported on maps or on forms.
- The toolbox is a good tool for people to retreive land-use and housing information in a short time.
The Planning applications toolbox was implemented for private use. Its features are:
- It can be used only by the district’s staffs. The Technical Division should use this toolbox to improve their daily issues.
- It helps user to manage and create different type of planning data. The toolbox is provided with many thematic drawing tools for creating exactly planning boundaries.
- It can be used for updating GIS data in database.
- The toolbox is not only good for technical staff to update planning data precisely and quickly but also valuable for manager to control planning areas within the district to meet the needs of people.
