Dear colleague,


Let me invite you to the conference Surface Models for Geosciences that is organised as a part of symposium GIS Ostrava 2015 in Ostrava, Czech Republic, EU in January 2015. We have prepared first call for papers that is available at


Papers are going to be reviewed and published by Springer in the Lecture Notes in Geoinformation and Cartography Series.


The deadline for full papers submission is October 20, 2014.


Do not miss an opportunity to meet with colleagues that are working with surface models.

Vision of the conference



Surface models are central parts of many spatial applications in geosciences. Quality of any analytical or visual result generated by such applications is tightly interlinked with the quality of digital surface models. Each phase of model’s development requires adequate methods and contains issues which may substantially decrease the value of the model and value of subsequent analysis. The associated uncertainty has to be under the experts control and the evaluation of uncertainty should be adequately utilized in any manipulation, analysis and visualization of surfasse models.


Traditional methods of DEM construction are still more substituted by semi-automated and fully automated methods of construction and change detection, incorporating new ways of imagery utilization, data collected by UAV or even data from crowdsourcing. Data is integrated from various data sources with different concepts (i.e. embedding 3D geometrical entities like buildings), with different spatial resolution (i.e.  personal micro-world captured by prospective
new mobile devices) and other qualitative parameters.


The progress pushes forward the frontiers of GI Science & Technology and opens questions like how to merge, maintain and utilize such data, how to deal with spatially variable quality, and how to efficiently store, manipulate, share and portray the Big Data.


Well-known analytical methods are extended to cover uncertainty issues, temporal aspects (i.e. analysis and processing of time series of DEMs), multi-scale analysis and 3D analysis (i.e. in urban space). Also many new approaches for surface presentation, especially in 3D static and dynamic visualization, rendering and 3D printing, attract increased interest in both public and science.


The main objective of the conference is to present and discuss new methods, issues and challenges encountered in all steps of gradual development, maintenance and utilization of digital surface models and their integration with various spatial data and models.


Furthermore, the conference provides a platform to discuss requirements, features and research approaches for virtual reality, 3D modeling, continuous field modeling and other geosciences applications.
