EuroSDR project3D Data Management in Urban Areas |
Time table - Questionnaire - Contact
In the last years, substantial technological progress could be observed in the areas of collection and visualization of 3D data. New technologies for the collection of 3D data (in particular airborne and terrestrial laser scanner) as well as an increasing performance of CPUs and GPUs have made it possible that 3D data can be acquired for large areas and handled on standard PCs.
However, 3D Geographical Information Systems (GIS) are very often not fully capable to handle the requirements of managing 3D data. One problem is that 3D data management and 3D analysis are in a state where 2D GIS was 10 - 15 years ago. The other problem is that typically no integrated IMAP (Input, Management, Analysis and Presentation) solutions are available, but different software systems are needed to process 3D data. The integration of the different systems must be realized with data import and export interfaces.
In order to investigate this situation more in detail and to find solutions for the future, we propose a project with the following aims:
- Identification of the state-of-the-art and future requirements of 3D data management
- Identification of deficits of existing 3D GIS software and formulation of suggestions to software manufacturers.
- Identification of research tasks of 3D data management in urban areas.
- Identification of country specific similarities and differences of 3D data management in urban areas in the EU.
Time plan
The project will consist of two phases. In phase 1 a survey will be conducted to identify the state-of-the-art of 3D data management. The outcome of this survey will be used to define one or more test scenarios for a performance test of different software systems in phase 2.
Phase 1
The time plan and milestones of phase 1 are presented in Table 1. The project start was the 119th EuroSDR meeting in Udine on 27th October 2011. A questionnaire will be used in order to indentify the state-of-the-art, the future requirements as well as existing problems.

Questionnaire
The final version of the questionnaire can be found »here. The questionnaire consists of three parts:
- Part A contains questions about the market and the state-of-the-art of 3D data management. The questions can be answered by selecting one or more predefined answers. Optionally it is possible to add free-text comments.
- Part B contains general questions about 3D data management. These questions can be answered with free-text.
- Part C contains a form that can be used for specifying test data and test scenarios that will be used for the performance test in phase 2.
All participants have four weeks time to comment the questionnaire. Change requests will be incorporated and the final questionnaire will be released on 23th December 2011. Then, participants have four weeks time to complete the questionnaire. An evaluation and summarizing of the results is planned to be released four weeks later on 2nd March 2012.
Phase 2
The time plan and milestones of phase 2 are also presented in Table 1. In phase 2 it is planned to carry out a performance test based on the results of project phase 1. Since these results are not available yet, the times and dates of the plan could be subject to slight variations. The procedure is identical to project phase 1. First, a draft version of the performance test will be released which can be commented. Change requests will be incorporated and the participants will have approximately five months time to carry out the test. A release of the final results is expected at the end of the year 2012.
Contact
Anyone who is interested in the project can comment the questionnaire. Please feel free to suggest any kind of changes. You can add new questions or modify existing questions. The change requests will be incorporated in a final questionnaire.
Do you have any suggestions concerning companies or institutions that should be included in the project, such as laser scanning companies, software provider or public institutions that are working with 3D geospatial data? Please feel free to contact them by yourself or send me a contact email address. All invited organizations are also requested to comment the draft version of the questionnaire within the next four weeks.
