“…Fenu et al, 2011; Ballantyne & Pickering, 2013; Fois et al, 2018; Orsenigo et al, 2018), the main threats to H. caput-felis are related to the degradation of the species' habitat from tourism and recreational activities and the expansion of housing and urban areas. Both the Spanish (Giménez et al, 2008; Agulló et al, 2010; Marco et al, 2011, 2016; Zaragozí et al, 2012) and Algerian (Agulló et al, 2017) coasts have experienced extensive urban development linked to tourism. We did not find that climate change, although a major driver of species extinctions (Gómez et al, 2015; Fenu et al, 2017; Orsenigo et al, 2018), is a threat to H. caput-felis but this could be because of the difficulty of detecting its effects (Fenu et al, 2017).…”

The assessment of the conservation status of a species is the first step in developing a conservation strategy. IUCN Red Lists assessments are an important starting point for conservation actions and the most commonly applied method for assessing the extinction risk of a species. In this study, the global conservation status of the rock rose Helianthemum caput-felis Boiss. (Cistaceae), a perennial Mediterranean plant, was evaluated using the Red List criteria. The distribution of the species was determined by monitoring historical localities and all other suitable sites along the western Mediterranean coasts for 6 years. For each confirmed locality, the ecological and population parameters and the main threats were recorded; these data were used in a quantitative analysis of the species' extinction risk. Our findings indicate there have been several recent extinctions, and there is a continuing decline in the species' area of occurrence, habitat quality and number of reproductive plants. The main threats are related to human activities. Extinction models indicate a probability of quasi-extinction risk of c. 30% in five generations or c. 45% in three generations, with the species likely to become extinct in seven currently known localities within the next 10 years. Application of the Red List criteria indicates H. caput-felis should be categorized as Endangered. This study confirms that legal protection and passive conservation measures are insufficient to guarantee the persistence of a plant species. Active conservation and management actions are needed to protect this and other threatened species of the Mediterranean Basin.

“…Currently there are thousands of FOSS projects ranging in size and popularity, with the most recognizable ones being Apache server and Mozilla (Mockus et al ). The movement has expanded into FOSS4G (free and open source software for geography) as discussed by Zaragozi et al (, and Steiniger and Hunter (). FOSS has been adopted and implemented by large companies such as Apple, IBM, Sun, NASA, and Google (AlMarzouq et al ).…”

Qualitative GIS is a relatively new methodological approach for analyzing and visualizing qualitative data within a geographic context. Qualitative data can take many forms, including interviews, documents, photographs, and audio and video clips. Content analysis for example, is an effective qualitative method for analyzing text-based data. We argue that basic concepts, (i.e. how to store data, data requirements, visualization techniques, and modes of analysis) within qualitative GIS have not been adequately defined, rendering difficult the replication of work performed and hindering the development of incremental knowledge in the field. Database management systems provide a means for storing, managing, and analyzing qualitative GIS data. A standardized and well-designed open source database system provides a mechanism for qualitative GIS projects, ensuring consistency and project replication. Qualitative GIS data stored in a database allows for additional visualization options, such as geographic word clouds. To demonstrate the concepts we performed content analysis on Master Transportation Plans from Calgary and Montreal using SpatiaLite, an open source database system. We developed Structured Query Language (SQL) queries to generate and populate groups and theme tables within the SpatiaLite database. We present our database design and queries in the hopes that they will help others conducting qualitative GIS research.

“…Geomatics field of study consist of several specialized fields including Geographic Information System (GIS), photogrammetry, remote sensing, Cartography and other scientific geospatial-based studies. Software application is very crucial in the process of obtaining, analyse, calculation, visualize, process and management of data as conducted by previous studies in environmental applications (Zaragozí. 2012;Jamaluddin et al, 2018;Abdul Rasam et al, 2014).…”

Abstract. Most universities students depend on the use of proprietary software as it has prominent capabilities to meet their needs. Although the proprietary software such as Adobe Flash Professional has a high capability to create a web-based multimedia system, budget constraints become the main reason why free software will be used as an alternative to proprietary software. This study is carried out to evaluate the potential free software for developing a web-based multimedia in cartography projects specifically for students in developing countries. Wix and Weebly are the two software that has been potentially explored among the ten selected software in the market. The current commercial software (Adobe Flash Professional) was also applied as a benchmark to the selected free software. This three software were individually utilised to design and develop a web-based multimedia of e-sport system and their technical capabilities were comparatively assessed according to elements of a common multimedia, website and other mapping assessment aspects. The finding showed that each of the software has unique characteristics and has successfully generated the end products according to the standard web-based multimedia title. Although these free software could produce a better looking, more flexible and time saving mapping platform than the end product created from the Adobe Flash Professional, they have limitation in creating menu function. This exploratory and cases study has also demonstrated that the alternative free software has potentials to replace the current proprietary software, while Wix is the best among the two selected software.
