Dear Colleagues,

Three-dimensional generation, representation, and visualization of spatial reality by integrating georeferenced databases into GIS has proved highly applicable in many fields when aiming to analyze process or phenomenon dynamics or simulate the integrated development of territory, based on virtual reality. The diverse applicability of 3D models in scientific research entails different types of management, depending on the purpose and software used in analysis, thus leading to a wide variety of output database types and standardized structures, which would be integrated into specific platforms. However, the greatest challenge is to successfully create databases and construct methodologies to achieve standardized 3D models to be used for visualization and in modeling for integrated territorial analysis and derivation of secondary databases. Challenges are mainly related to the processing capabilities of computing technology, vector and raster data acquisition, possible process errors, and relation and compatibility of spatial digital data that are used for generating the final 3D models. All these emphasize the difficulties in the realization of 3D models given the multiple factors that must be considered. Modeling is therefore subject to a certain degree of subjectivity, hence the absolute need for highly accurate and correct three-dimensional models to be created and used in specialized research.

This Special Issue aims to publish research studies on the creation of 3D models based on case studies in various fields such as geography, spatial planning, agronomy, geology, engineering, hydrology, urbanism, construction industry, virtual and augmented reality, etc. Another main purpose of this Special Issue is to highlight possible errors that can occur in the modeling process and methodology construction to achieve a standardized realization of 3D models for integrated analysis and dynamic visualization of the territory and built environment.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. ISPRS International Journal of Geo-Information is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
