In order to identify the Land Units of the Sarno river basin, research was conducted by analyzing the different environmental characteristics and drawing up thematic maps and synthesis GIS maps. In geomorphological terms, the study area has great carbonatic structures which, together with the Somma-Vesuvius volcanic complex, delimit a Plio-Pleistocene depression filled by transitional environment deposits and grooved by an extensive hydrographic network. Analysis of various aspects concerning the morphology, lithology, soil, vegetation and human impact on the area led us to identify 32 Land Units with homogeneous geolithologic, morphometric and geomorpho-logic attributes. The Map of Land Units is derived from the construction and synthetic overlay of various thematic maps comprising the Slope Map, the Lithologic Map, the Vegetation Map, the Soil Map, and the Land Use Map. It is an extremely useful innovative document both in environmental analysis and in land use planning in that it allows us to extract basic physical, biotic and impact themes to be elaborated for applicational uses.

This paper builds upon studies employing a syllabi-based methodology that suggest a tendency for critical geographic information science (GIS) courses to emphasize reading/discussion about GIS without actually doing GIS, and for traditional GIS instruction courses to emphasize the technical capacities of GIS software without incorporating critical theory in substantive ways. However, through ethnographic evidence we reveal that there is likely more innovative theory-practice transcending pedagogies being utilized than would necessarily show up in such a syllabi-based methodology. There are also very real and differentially manifest pragmatic, departmental, and institutional barriers in place to effectively incorporating critical social theory into courses that actually do GIS. We first catalogue these barriers as a means of ascertaining what can (and cannot) be done to overcome them through GIS pedagogic innovation. We then outline the (often-veiled) pedagogic strategies deployed by critical GIS scholars today to navigate and circumvent these barriers.

Geographical indications (GI) rights are unique as they have a regio-cultural basis and involve the knowledge and skill of communities. The enactment of the Indian GI Act 1999 was aimed to improve the economic status of the communities and key products for export by registration of GI. Analysis of the inspection body particular, institutional mechanism, and registration process revealed the need for elaboration of GI protection mechanism. Of particular significance is the need to protect the reputation of GIs, strengthen the local registration mechanism, and identify a mechanism for monitoring and conservation of GI. Analysis of food GI such as Bardhaman Sitabhog and Mihidana provide insights on the need for an enhanced protection mechanism to be provided under the GI Act and the rules which have a significant bearing on the post GI sustenance.

Laparoscopy-assisted gastrectomy for advanced gastric cancer still remains controversial. The aim of this study is to compare oncologic feasibility and technical safety of laparoscopic versus open gastrectomy for advanced gastric cancer with D2 lymphadenectomy by comparing patients' short-term postoperative outcomes.

Citizen science websites are emerging as a common way for volunteers to collect and report geographic ecological data. Engaging the public in citizen science is challenging and, when involving online participation, data entry, and map use, becomes even more daunting. Given these new challenges, citizen science websites must be easy to use, result in positive overall satisfaction for many different users, support many different tasks, and ensure data quality. To begin reaching these goals, we built a geospatially enabled citizen science website, evaluated its usability, and gained experience by working with and listening to citizens using the website. We sought to determine general perceptions, discover potential problems, and iteratively improve website features. Although the website was rated positively overall, map-based tasks identified a wide range of problems. Given our results, we redesigned the website, improved the content, enhanced the ease of use, simplified the map interface, and added features. We discuss citizen science websites in relation to online Public Participation Geographic Information Systems, examine the role(s) websites may play in the citizen science research model, discuss how citizen science research advances GIScience, and offer guidelines to improve citizen-based web mapping applications.

Background: This study aimed to compare and evaluate the spatial and statistical models to predict PM2.5 concentrations at ground level and at the macro scale in Mashhad. Methods: To investigate the status of air pollution in the metropolis of Mashhad air, three interpolating models including Ordinary Kriging (OK), Universal Kriging (UK) and inverse distance weighting (IDW) were used. Root Mean Square Error (RMSE) and correlation coefficient (R2) were employed to compare three models and choose the best one. As well as to select the most optimal conditions for the implementation of both OK and UK, used from Standardized RMSE. Results: The results showed that the highest monthly average of PM2.5 was belonged to September and “Sakhteman” station (95.1 μg/m3). Also, the lowest monthly average pollution had happened in "Torogh" station, in November (15.5 μg/m3). According to the data, the OK had the lowest RMSE (10.601) compared to the UK and IDW. Lower RMSE represents lower error between the predicted and measured values. So, OK model selected as better one in interpolation. Also, Judging by correlation coefficient (R2), the highest correlation belonged to OK compared to other two models. UK model showed a greater standard error of predicts than OK. The greatest standard errors of prediction were related to areas that have more distance from air pollution monitoring stations. Conclusion: it should be noted that the production and use of geo-referenced maps could quickly provide spatial analyses, and because it can be combined with GIS, the user is able to investigate the influence the various concentrations of contaminants.

A geographical information system(GIS)is used to capture, store, retrieve, analyzed and display the spa- tial(locationally defined)data. In contrast to traditional GIS, multimedia GIS is not only able to collect, analyze and store the data in traditional formats i.e. text, images(pictures)and graphs but also audio(sound), animations and video (moving pictures)as well. In this paper the advantages of multimedia GIS over traditioal GIS are explained.

Explaining much of what exists today or has happened in the past can be approached from both spatial and temporal perspectives. Often overlooked by traditional methodologies and paradigms the locational element can provide significant new analytical perspectives and explanations that open up fresh opportunities for research. The use of Geographic Information Systems (GIS) technologies in the pursuit of historical research is emerging as an intriguing approach to understanding our world and its underlying historical dimension.
