Landscape photography database to support landscape change analysis

Repeat photography is an efficient effective and useful method to identify trends of changes in the landscapes. It was used to illustrate long-term changes occurring in the landscapes. In the Northeast of Portugal landscapes changes is currently driven mostly by agriculture abandonment and agriculture and energy policy. However there is a need to monitoring changes in the region using a multitemporal and multiscale approach. This project aimed to establish an online repository of oblique digital photography from the region to be used to register the condition of the landscape as recorded in historical and contemporary photography over time as well as to support qualitative and quantitative assessment of change in the landscape using repeat photography techniques and methods. It involved the development of a relational database and a series of web-based services using PHP: Hypertext Preprocessor language and the development of an interface with Joomla of pictures uploading and downloading by users. The repository will make possible to upload store search by location theme or date display and download pictures for Northeastern Portugal.
