GIS eased into geography without much discord until the 1990s, when a flurry of commentaries about the relative merits of GIS made their way into a number of geographic journals. The ensuing decade was marked by varying degrees of friction between GIS practitioners and their critics in human geography. Despite the methodological chasm between the two groups, little discussion of the implication...
Incorporating the temporal element into traditional GIS is a challenge that has been researched for many years and has many proposed solutions. The implemented system “Extended Dynamic GIS” or EDGIS is based on the “geo-atom” and Space Time Point (STP). EDGIS provides a platform for spatiotemporal data representation, storage, and query in order to address the need for a dynamic GIS to manage c...
Background and Objectives: Public health issues and the spread of disease correlate with geography and always have locational aspects.. Therfore, in this study the spatial analysis of malaria disease reports between 2004-2014 in Bam were investigated using geographic information system (GIS). Materials and Methods: In this cross-sectional study, information on positive cases of malaria were ...
Biography Professor and Chair of the Department of Geography at the University of California, Santa Barbara and Director (Santa Barbara) of the National Center for Geographic Information and Analysis. Author of three books and about 80 articles in GIS, cartography and remote sensing. Former President of the Cartographic and Geographic Information Society. Only person to have given two Geocomput...
Building Information Modelling (BIM) provides a detailed 3D geometrical model with rich semantics which go beyond the standard Computer-Aided Design approach. In contrast, Geography Information Science (GIS) offers powerful spatial analytical tools. This paper seeks to propose and innovative research approach integrating some aspects of BIM and advanced GIS analysis. This may lead into beyond s...
تبدیل داده های ماهواره اى به فرمات بردارى مستلزم طبقه بندى و تفسیر اطلاعات سطح پایین با حفظ دقت اندازه گیرى و جزئیات فضایى است. در صورتى که راسترى نمودن یک نقشه که با داده هاى ماهواره اى مطابقت و سازگارى داشته باشد به مفهوم تجزیه و تنزل اطلاعات کارتوگرافى سطح بالاست. از این رو در ترکیب و مجتمع سازى داده هاى تصویر و کارتوگرافى در یک ساختار داده اى باید به اینگونه مبادله ها توجه نمود.
سیستم مدیریت پایگاه داده (DBMS) از مجموعه داده هاى مرتبط و مجموعه برنامه هاى کامپیوترى براى دسترسى به آن داده ها تشکیل شده است. به مجموع داده ها معمولاً پایگاه داده گفته مىشود و مجموعه برنامه ها معمولاً مدیریت پایگاه داده نامیده مى شود. به علت اهمیت اطلاعات در همه طرح هاى عمرانى در تمامى سطوح پایگاه داده یک منبع با ارزش محسوب مى شود. از این رو مفاهیم و اصول آن نیاز به بسط و توسعه دارد. هد...

Although feminism and the field of geographic information systems and science (GIS) have only recently begun speaking to each other, the feminist mapping subject is emerging across a variety of sites – academic, professional, and lay. However, it is most articulated in the work of critical GIS scholars. Both male and female, they are committed to nonpositivist practices of knowledge production ...
T he map has evolved over the past few centuries as humanity’s primary method for storing and communicating knowledge of the Earth’s surface. Topographic maps portray the general form of the surface and its primary physical and cultural features; thematic maps show the variation of more specialized properties such as soil type or population density; and bathymetric maps and hydrographic charts ...
