ABSTRACT
LiDAR Damage Assessment for Disaster Relief Efforts in Urban Areas
LiDAR data can be combined with spectral imagery to efficiently provide map and information support for relief and recovery in the aftermath of a disaster, such as an earthquake. This presentation will explain how LiDAR data can be used for crisis management, including the 3D reconstruction of urban areas in Port-au-Prince, Haiti, following the January 12, 2010 earthquake. 3D maps constructed from LiDAR data aid emergency management teams in determining the location of collapsed and standing structures, as well as supporting landing and routing tasks. In this study, the ENVI LiDAR processing tool was used to extract buildings and significant debris coverage from a dense LiDAR point cloud collection from the aftermath of the earthquake. ENVI image analysis software was used to fuse image data with the processed LiDAR data for enhanced road extraction efforts. Debris information was combined with the extracted road layer and used to construct an intact road network for input in ArcGIS Network Analyst to support ground team routing. Debris coverage and 3D urban topography was also used as an input into a helicopter landing zone and to identify areas to focus rescue efforts.

He improved his skills in private en public activities in many topics of positioning, surveying, geo-information and public governance as well. In the past he was directly involved in the establishing of Geonovum and the integration of the National Mapping Agency (Topografische Dienst) and Kadaster.

ABSTRACT
Kadaster succeed in generating ortophotos with a geometrical precision of 3 centimeters made by an Unmanned Aerial Vehicle (UAV)! This result is an international break-through in the search for useful applications of UAV's and photogrammatry in surveying. The experiment was started to use orthophotos in cadastral verification and surveying borders of ownership. In the actual process many customers are not able to make their attendance during juridical verifications and simply don't appear. It effects in making new appointments with customers to do verifications at other moments which costs extra time, money and effort of cadastral employees and customers as well. To improve this process for customers and Kadaster, an experiment started to use orthophotos. Because of its features, actual orthophotos with highly geometrical precions are highly representive of a new cadastral situation. The idea is to give customers an orthophoto on which they can verify their new border of ownership and respond during some weeks. To make well orthophotos, Unmanned Aerial Systems (UAS) seems to be a perfect instrument, because of the limitations of quality and highly costs of conventional aerial pictures. If orthophotos could be made with a minimal geometrical precision of 6 centimers - the actual tolerance of conventional cadastral surveying- they could also be used for cadastral surveying. Several experimental flights were made above Austerlitz and Nunspeet. Automatically taken pictures were stitched, georeferenced and postprocessed to orthophotos. In the end it resulted in a prooved process for generating orthophotos with a geometrically high accuracy of 3 centimeters.

BIO
Rob Peters is crisis information manager and CIO of a Dutch Public health & Safety District, called Kennemerland. His day to day work involves bridging disciplines, semantics and stakeholders to share information that will help to mitigate the next plane crash effects. He has worked 10 years in Geo-related information management, starting with project leadership of www.overheid.nl , the Dutch National gov portal. The role of Spatial Data infrastructures as enabler for government services has been the central them to his PhD thesis about the legitimacy of Law. As member of the taskforce architecture, he is responsible for writing the VERA, the National reference architecture for safety regions. He is representative of the Dutch safety region innovation platform and of the Base registries steering committee on behalf of the Fire brigade information managers. Rob received several international best paper awards on geo-semantics. He recently co-chaired the Gi4DM conference inviting his fellow crisis managers to demonstrate current practices and challenges in bad-weather crisis communications.

ABSTRACT
The Dutch fire brigades have spent many millions on geospatial data in recent years. The goal of this bottom-up effort was to enable our vehicles to have the knowledge about the object they were driving at (at top speed).The programme was called the ‘digitale bereikbaarheidskaart’ (digital approachability map). Having very little framework to work with, the implementation of those efforts met with some hard reality lessons. In parallel the Dutch National Safety council spent another huge investment on digital enablement of Netcentric crisis management. At the very end of 2012, those two efforts met and created the National ‘proxyserver’. This is probably the first sectoral information exchange server in The Netherlands and its very existence may mark a new area for SDI practices. It encompasses SKOS based on the fly semantic interoperability , high performance map layer updates and distributed synchronization with regional hubs. Key-elements in its design were the fundament built on the base registry addresses and buildings (BAG) and the parallel development of IMgeo2 . The next design phase will seek to involve CityGML, synchronization with municipal maintenance systems and some 3D coverage where we face underground incidents. It took specialist cross organization multi-team work to achieve such a stage of a national generic platform infrastructure. Looking back the investment actually could be seen as small. The user perspective could provide the geo- community with ammunition to support similar initiatives with implementation frameworks in the future.

ABSTRACT
Terrestrial Laser Scan technology now days is highly developed and the use of cloud data is getting more and more accepted in different applications. Can Terrestrial Laser Scan be as tools to support Crisis Management? The paper will focus how Terrestrial Laser Scan can be used for Crisis Management. The steps of the Laser Scanning process will be presented from data capturing, data registration and finally data converting from cloud data to vector data. The advantage of such tools will be presented based on live demonstration to show how objects can be recognized automatically, the converting of each object into vector format can show the strengths of Terrestrial Laser scan and for sure the limitation of such technology will be discussed either.

ABSTRACT
Development of a 3D engine for near real time 3D visualization and analysis on airports
The goal of the project Geo-Spatially Enhanced Situational Awareness for Airport Management (SESAAM) is to develop methods for assembling and providing a Complete Operational Picture (COP) for the management of all relevant movements on an airport. Special challenges are (i) the suitable combination of expensive positioning technology (e.g. multilateration) for safety-critical areas/ tasks and low-cost technology (RFID, tightly coupled WLAN/GPS) for others, and (ii) the development of methods for processing and visualizing the COP using an open system architecture but at the same time fulfilling requirements regarding completeness, reliability, and low latency. For 3D visualization and analysis of near real time 3D data (position and object information of planes and vehicles) a C++/OpenGL based 3D engine has been developed (COP-VIS). It supports multiple screen modes for 2D/3D and tabular data viewing and reporting. Object interaction can be object to object, object to 2D areas/ lines (fences and gates) or object to rule, where a rule can be an abstract description of a 3D body (eg. a sphere or cylinder) in combination with a defined activity in case condition becomes true (alert, recolor, logging). Position and object data is derived from a relational database system and display output to the various screens is directed by user defined queries. To achieve a near real time operation, developed COP-VIS engine analyses processing time per operation, alerts if processing time exceeds user defined maximum duration values and automatically switches off data layers if permitted. For landscape visualization COP-VIS supports textured height maps. Day time dependent lightning direction is supported as well.A combination of various low cost and certifiable positioning technologies and the developed COP-VIS engine is tested on Salzburg Airport (Austria). The results of SESAAM contribute to increasing airport operation efficiency and airport ground traffic security particularly due to low visibility as well as to the reduction of delays.

ABSTRACT
Indoor spatial information and crisis management
It is known that we spend more than 80% in indoor space our daily life. This implies that indoor spatial information is a crucial component of proper crisis management such as evacuation or rescue in case of fire like outdoor information. Due to recent trends of constructing high and complex building, indoor spaces become more and more complicated, and indoor spatial information is also getting important for efficient management of space and resources. In this talk, we will present recent progress on methodologies and applications of indoor spatial information including current activities for OGC IndoorGML, which is a candidate standard of indoor spatial information. And we will also discuss how the indoor spatial information and the standard can be applied for crisis management.
