چکیده مقاله :

فناوری‌های بصری‌سازی می‌توانند ابزار قدرت مندی برای تبادل داده‌های علمی مدل‌های آمایش محیط‌زیستی بین پژوهش گران و استفاده کنندگان عام باشند. عدم یکپارچگی و غیرجذاب بودن نتایج فرآیندهای آمایش سیمای سرزمین از مشکلات عمده ی این افراد است. افراد غیرخبره معمولاً بخاطر فشردگی نقشه‌‌های گرافیکی گیج و سر در گم می‌شوند و قادر نخواهند بود این اطلاعات را به صورت تصاویری از سیمای سرزمین در ذهن خود ترجمه کنند. یکی از راه حل ها برای حل این مشکل استفاده از پیشرفت فناوری در رابطه با ابزارهای تصویرسازی سه‌بعدی است. ادغام سیستم های اطلاعات جغرافیایی با فناوری تصویرسازی سه‌بعدی اخیرا در برنامه‌ریزی شهری و طراحی سیمای سرزمین مطرح شده‌است، بنابراین در این مقاله سعی شده است تا برخی از اصول و مفاهیم اولیه در این رابطه جمع آوری و ارایه گردد. این مقاله به طورکلی در دو بخش اصلی تنظیم شده است، بخش اول به بیان اهمیت سه‌بعدی سازی داده های مکانی و بررسی تفاوت قابلیت‌های سه‌بعدی سازی در محیط نرم افزارهای CAD و GIS می پردازد و هم‌چنین به برخی از مشکلات و راه‌حل‌های مربوط به توسعه نرم‌افزارهای 3D GIS اشاره می‌کند. در بخش دوم برخی از سیستم‌های موجود سه‌بعدی ‌سازی معرفی و توضیح داده می‌شوند. مقاله ی حاضر در پی آشکارسازی قدرت 3D GIS، در تعامل بین برنامه‌ریزان، مدیران و مخاطبان عام است.

چکیده انگلیسی:

Visualization technologies are powerful tools for communicating the scientific outcomes of environmental planning models between the researchers and public participants. A common problem of landscape and environmental planning is that projects are rarely presented in a coherent and stimulating manner. Laypersons are usually overwhelmed by abstract, graphically sparse mapping and are unable to translate this information into landscape images. One of the solutions of this problem is benefit from improvements of 3D visualization technologies. Recently Integration of GIS and three-dimensional visualization technology has been introduced in urban planning and landscape design, so this paper attempts to explain some of the principles and basic concepts in this regard. This paper is generally presented in two parts: the first part expresses the importance of 3D visualization of spatial data and compares different capabilities of 3D making in CAD and GIS softwares, and it has also been referred to some of the problems and solutions of developing 3D GIS softwares. In the second part, some of the three-dimensional systems are introduced and explained. This represented paper is trying to reveal the power of 3D GIS in creating interaction between planners, managers and the general audience
