The application design is made of two parts, i. e. a common database storing
and processing data, and a client application to visualize data and operate data-
base procedures. The database supports the tracking of time and user performing
changes, so that the history of any object can be reconstructed. The document

CAMPUS 1.0 is designed as a set of 19 gvSIG extensions monitored by the main
CAMPUS extension. These extensions can also be further extended by any other
party who would like to customize further, continuing the process of extensibility
of both gvSIG and CAMPUS.
CAMPUS 1.0 uses the following gvSIG tools:
•
geospatial libraries (vividsolutions, geotools packages);
•
database manager (GDBMS project);
•
scripting console (extScripting project);
•
GUI objects for representing data table content, geospatial and topology
symbols (com.iver.cit.gvSIG.project package); and
•
Symbology package (FMap).
GvSIG is based on the extensible platform ANDAMI (see Figure 4.5.) which per-
forms reading and mounting of extensions immediately after application start.
ANDAMI also provides a user interface for placing menus, toolbars and user win-
dows and offers a multilingual support. Text files (.properties) for each language
need to be added to the config folder of a _appANDAMI project, which contains
text labels in a term=translation manner. This allows further use of the application
in other languages.

The Cambodian cadastre would seem the ideal candidate for the implementa-
tion of free and open-source software. Technical and financial resources are lim-
ited in Cambodia, one of the poorest countries in South East Asia. During the
Khmer Rouge regime in the 1970s, all land records were destroyed. Now, a land
register is being built up from scratch through systematic land registration, village
by village. Each month, around 25,000 land parcels are registered through a dig-
ital land registration system. Computers and software licenses have been bought
to equip land registration teams in 15 provincial cadastral offices. The costs to
maintain the system and to meet future demands in terms of data volume and
user requirements are considerable. The idea of using of open-source software as
an alternative to proprietary database and GIS software is met with enthusiasm,
and efforts are underway to implement open-source software solutions. The obvi-
69
ous financial benefit is one of the reasons why open-source solutions are popular
in Cambodia. However, the cost of software licenses is probably the least of the
many chal lenges that the Cambodian cadastre is facing.
