Subject: PhD position about storage/update of massive 3D city models at the TU Delft

Date: February 2, 2015 10:18:43 CET

To: Hugo Ledoux <h.le...@tudelft.nl>, Jantien Stoter <J.E.S...@tudelft.nl>

Dear colleagues,

The 3D geoinformation group (http://3dgeoinfo.bk.tudelft.nl) at the
Delft University of Technology in the Netherlands is currently
offering a PhD position about the efficient storage, update and
dissemination of massive 3D city models. This is a 4-year position
part, funded by the Dutch Technology Foundation (STW), and part of a
large project in the Netherlands in which 3 universities and 11
organisations are involved.

For more details about the position and how to apply:

The deadline to apply is March 2nd 2015.

Regards,
Jantien Stoter & Hugo Ledoux

# Efficient storage, update and dissemination of massive 3D city models

The Netherlands has recently launched a 3D map covering the whole
country in which all buildings, roads, trees, canals are 3D
geometries.
It was constructed by adding the third dimension, obtained
from airborne laser-scanners, to the objects in the 2D topographic
map.
This leads to a massive amount of information: 15M+ objects,
billions of elevation points, and billions of triangles.

The aim of the project is to investigate and develop methods to
efficiently store and maintain the dataset in a database, and to
disseminate it to practitioners.
The existing open-source database
solutions for managing 3D volumetric objects will be tested with
massive datasets and improved, if necessary.
The biggest challenge is
the management of massive TINs (triangulated irregular networks) in a
database.
The PhD student will have to design and develop new data
structures, implement them, and compare different alternatives (in
terms of storage space, query time, etc).
Furthermore, a prototype
download service that generates 3D datasets tailored to specific
applications will be explored, eg WFS for 3D objects and massive
triangulations.

The project will take place in the 3D geoinformation group under the
supervision of Prof. Dr Jantien Stoter and Dr Hugo Ledoux.
It is fully
funded by the Dutch Technology Foundation (STW), and it is part of a
large project in the Netherlands in which 3 universities and 11
organisations are involved.
We expect the PhD student to collaborate
with the other researchers and practitioners involved in the project.


# Research group

The 3D geoinformation research group (http://3dgeoinfo.bk.tudelft.nl),
part of the Faculty of Architecture and the Built Environment, focuses
on the technologies underpinning geographical information systems
(GIS), and aims at designing, developing and implementing better
systems to model 3D cities, buildings and landscapes. It is a
multidisciplinary group of around 12 people, including computer
scientists, geomatics engineers, and geographers.
It has a history of successful collaborations with the industry and
the government: its research has led to software, standards and
patents for the management of 3D geographic information.


## Doing a PhD at TU Delft

## Job requirements

Applicants should hold an MSc degree (or almost completed) in
geoinformatics/geomatics, computer science, applied mathematics, or in
a related discipline. They are expected to have good programming
skills, a good command of English (oral and written) and strong
interest in 3D modelling and/or computational geometry. Prior
experience with GIS is highly desirable.


## How to apply
