Abstract
Natural and man-made disasters have had a great impact lately
worldwide. As global communication intensifies we are becoming
increasingly aware of the amount of damage that is done in terms of
injuries to and loss of humans and materials. Therefore a tremendous
amount of efforts goes into activities aiming at disaster mitigation and
early and effective rescue actions.In this context disaster response
planning plays a specific role. Disaster response planning consists of
three components: (a) development of damage simulation models, (b)
methods and models to rapidly assess damage, and (c) methods to allocate
limited resources in an optimal way.Among the various techniques applied
in this domain remote sensing technology can contribute in particular to
(a) and (b), but to a certain extent also to (c).
In this presentation the emphasis will be on the characteristics and use
of image-based techniques.We dispose nowadays of a large spectrum of
different sensors, operating from a variety of platforms like satellites
(optical, radar), aerial (images, LiDAR, helicopters, UAVs) and
terrestrial (Mobile Mapping systems, flying “mosquito†robots). We
will show how these techniques can be used both for simulation of
events, risk analysis and for the empirical analysis of events and
prevention, and for the monitoring of actual events.The true challenge
today lies not so much in sensing, but in data processing. Especially if
on-line processing and real-time responses are required, the lack of
performance in data processing techniques is still an annoying factor.
This presentation will cover all aspects from sensing to data
processing, supported by a number of exemplary international projects.

Abstract
The April 2015 major earthquake took place about 76 km northwest of Kathmandu followed by more than 300 aftershocks killed 9000 people and injured 25,000 people in Nepal. Recent official report by Government of Nepal (GoN) indicates that these earthquakes have affected the lives of eight million Nepalese people which is about one third of total population. This is a dangerous natural disaster which causes tremendous impacts on human vulnerability and leads to human, structural and financial losses and destructions. At international level, there are two major frameworks namely Hyogo and Sendai frameworks that address to the Multi-hazard environment including the threats to people’s lives, livelihood and assets. These frameworks can provide very good guidance to develop an action-oriented framework at the country level. Since land is fundamental to the recovery process, this presentation discusses land issues including access to land for shelters, protection of land rights, livelihood and early recovery from the earthquakes, and highlights how to incorporate these land issues into the action-oriented framework for recovery. Finally, this presentation presents land matters and Geo-information needs for post disaster reconstruction planning process within the context of Sustainable Development Goals (SDGs).

Abstract
The adoption and integration of geospatial information across the wide expanse of socio-economic sectors continues to advance at a rapid rate. For nations facing high risk of natural disasters, geospatial information is a critical element in the development of disaster risk management systems. A plethora of innovative geospatial technologies available today will help not only to produce these critical information, but also enable analytics to support quick and effective decision-making . Rajan Aiyer will discuss some of these technologies and how they are applied in pre- and post-disaster projects.

Abstract
Disasters are non-ordinary events and come in many shapes and sizes. They can be characterized by extraordinary delivery of wind, water and fire, and in the case of earthquakes, energy that moves the very ground we stand upon. Although the occurrence of disasters may be unexpected, measures can be taken to prepare for them. We can be ready to respond and understand what we must do to recover. Geospatial technologies, for example, can provide community leaders, planners, policy makers and emergency responders with critical data and disaster analysis tools. Satellite programs acquiring image data that are regular, synoptic and complete in coverage are invaluable for disaster assessment because they provide both the “before†and “after†views. Imagery from airborne and unmanned aerial systems (UAS) also provide critical information to assist responders with prioritizing their actions, planning paths of evacuation and delivering aid and supplies. Combining imagery with geographic information systems (GIS) and existing data of Spatial Data Infrastructures also allows analysis of current conditions and past disaster events in order to model risk, patterns of damage and predictions of future events. Spatio-temporal analysis of time-series remotely sensed imagery, 3D terrain data and point clouds provide advanced geovisualizations and animations that allow us to virtually experience disaster scenarios and evaluate possible responses. This presentation will discuss geospatial technologies and analyses being conducted by researchers at the Center for Geospatial Research (CGR), Department of Geography at The University of Georgia, USA that can be used for disaster preparation, response and recovery. Case studies will be presented using multi-temporal imagery from satellite, airborne and unmanned aerial systems (UAS) platforms that document current conditions and establish baselines for assessing future changes. Training staff and approaches for easy access to geospatial technologies also will be addressed because people with local knowledge and who are on-site when disasters strike are the most important component of disaster management.

Abstract
The 2015 earthquake sequence in Nepal, including the Mw 7.8 Gorkha earthquake of 25 April and the Mw 7.3 Dolakha earthquake of 12 May, triggered several thousand landslides in Nepal. These were predominantly located in high-relief areas of the Lesser and High Himalaya, north and northeast of the epicentre of the 25 April earthquake. A number of different organisations used optical and radar satellite imagery to map landslides in the immediate aftermath of the earthquakes. This mapping effort was largely successful in identifying the main areas that were affected by landsliding, along with the locations where major disruption to roads and other infrastructure should be expected. At the same time, the mapping effort was hampered by a number of different issues, including lack of suitable cloud-free imagery, difficulty in identifying coseismic landslides, and coordination between the different teams, data providers, and potential end-users. Here, we review the earthquakes and the patterns of coseismic landsliding, emphasising the key role of satellite imagery in allowing rapid assessment of the landslide hazard. We also describe the longer-term effects of the earthquake on landslide occurrence in the region, focusing in particular on the Upper Bhote Kosi valley, Sindhupalchok, as a representative example of the wider earthquake-affected area.

Abstract
Technology is changing the way in which we live our lives including
the way we work, communicate, socialise, purchase goods and services and
relax. Modern disaster reporting is becoming increasingly sophisticated
with the ready access to social media and user-friendly online mapping
tools. Citizen engagement in location enabled disaster reporting is more
obvious, and the availability of crowd generated geospatial data is
higher than ever before. Crowd generated geospatial content is current
and more diverse than conventional geographic information; however,
quality and credibility issues exist. Although spatial data
infrastructures (SDIs) have proven to be successful in supporting
disaster management activities in the past, delays in providing public
mapping portals and gaps in data are common. Crowd support and crowd
generated spatial data have the potential to speed up disaster
management actions and disaster mitigation actions.
Formal or authoritative SDIs have formed the base mapping framework for
emergency management authorities to utilise during emergencies. However,
these data are often not available for citizens to access quickly during
a disaster and therefore crowd responders are utilising other less
authoritative mapping sources to respond during disasters. The
utilisation of base maps such as OpenStreetMap, Google Maps or Bing Maps
is commonplace for crowd sourced mapping. In some instances, these base
maps are superior to the officially available government maps whilst in
other cases the official mapping is more current or complete. This
presentation will discuss the role of crowd sourced mapping during
disasters, the challenges data quality and credibility, the
opportunities that crowd sourced data presents and the role of
government agencies in spatial data access and management to support
disaster management.

Abstract
A study of disaster recovery and land tenure/land administration in other countries allows us to identify lessons for Nepal. Lessons can be drawn from previous earthquake events such as Haiti, and New Zealand. A number of key land administration challenges faced during the earthquake recovery and reconstruction periods are identified and summarised. This includes priorities for tenure security, land use planning, and property valuation. These priorities will often differ from country to country but common themes and options emerge.

Abstract
The United Nations in September agreed to the 2030 Agenda for Sustainable Development. The 17 Sustainable Development Goals and 169 targets as agreed demonstrated the scale, reach and ambition of this Agenda. These goals and targets should inspire and galvanize actions over the coming decade in areas crucial and important to humankind. Earlier in the year, the global community adopted the Sendai Framework for Disaster Risk Reduction with an emphasis on the importance of developing, providing and improving disaster risk information leveraging on geospatial information technologies. Under the United Nations Framework Convention on Climate Change, there is the much anticipated 21st Conference of the Parties later this month in Paris. Next year, the global community heads into Habitat III Conference seeking the New Urban Agenda that will provide solutions for the complexities within human settlements and urbanization. These international agendas and developments all have a people-to-place dimension.
Christchurch, New Zealand
Abstract
New Zealand typically experiences 20,000 earthquakes annually. However the southern city of Christchurch was considered a relatively quiet seismic area – until September 2010. What followed over an eighteen month period were 13,000 earthquakes and aftershocks. Christchurch suffered catastrophic damage to buildings and loss of life. Geospatial professionals were needed immediately to support the rescue effort by Urban Search and Rescue, Civil Defence, Police and Army. Support from Surveyors and GIS experts increased as the emergency response turned into recovery and then rebuild of the city. Today, five years on, the need for surveyors and GIS specialists is still as strong as ever and it is important to recognise their contribution to disaster recovery.

Abstract
Along with the damage to buildings and infrastructure, the April 25,
2015 Mw7.8 Gorkha earthquake caused quite significant deformation over a
large area in central Nepal with displacements of over 2 m recorded in
the vicinity of Kathmandu. In this paper we consider options for a
modernized geodetic datum for Nepal that will have the capacity to
correct for the earthquake displacements and ongoing tectonic
deformation associated with Nepal’s location on the India/Asia plate
boundary. The current Nepal datum is a classical datum developed in 1984
by the Military Survey branch of the Royal (UK) Engineers in
collaboration with the Nepal Survey Department. It has served Nepal well
however the recent earthquakes have provided an impetus for developing a
semi-dynamic datum which will be based on the most current available
ITRF and have the capacity to correct for tectonic deformation.
In the scenario we present here, the datum would be based on be ITRF2014
with a reference epoch set some time after the end of the current
sequence of earthquakes. The deformation model contains a grid of the
secular velocity field combined with models of the Gorkha Earthquake and
the May 12 Mw7.3 aftershock. We have developed a preliminary velocity
field by taking published velocities for Nepal and adjacent pars of
China and India from five previous studies and aligning them to the
ITRF. We are currently working on developing patches for the co-seismic
part of the deformation using published dislocation models. While these
models do a reasonably good job of modeling the deformation, there are
some significant discrepancies between their predictions and the limited
GPS measurements. We hope to improve these models by developing revised
grids that will incorporate increased GPS and INSAR measurements of the
deformation field. Top level control would be based on a CORS network
based around the existing Nepal GPS Array. Coordinates for existing
lower order coordinates would be determined by readjusting existing
measurements and these would be combined with a series of new control
stations spread throughout Nepal.

Abstract
Designing and implementing comprehensive and efficient policies for preventing and addressing the impact of natural disasters represent significant political and socio-economic challenge for any society. This challenge manifests itself in the conundrum of finding the right balance between the needs and the rights of affected population, the existing legal frameworks and the societal demands and the available state and community resources. There is no universal recipe for achieving this balance and each society has to find its own. However, there are set of principles which can guarantee equitable and efficient policies and mechanisms such as the principles of participation and consultative decision making. This discussion paper will set to explore these principle and elaborate on the variety of feasible and efficient models for addressing housing, land and property issues before, during and after natural disasters.
