Resumen:
In the last years there has been a continuous growth in functionality of geographic information systems (GIS) resulting in many different software artifacts. Even though each GIS is used in different areas
with different objectives, they all share many features and requirements
and therefore it is possible to apply techniques based on intensive software reuse, such as software product line engineering (SPLE). Although
there has been much research on software product line engineering in
the last years, the definition of a software product line for the domain of
geographic information systems has not been undertaken.
In this work we identify the requirements and functionalities of a generic
product for a web-based geographic information system, grouping them
into commonalities that allow us to reuse many software artifacts, and
variabilities that allow use to configure different products. Then, we define the functional and technological architecture of a software product
line that uses current technologies for web-based application development. Finally, we design a tool to configure and assemble the components to generate the possible products. The resulting platform is flexible
enough to adapt each product to the specific needs of each customer.
