3D GEOSPATIAL INDOOR NAVIGATION FOR DISASTER RISK REDUCTION AND RESPONSE IN URBAN ENVIRONMENT
Disaster management for urban environments with complex structures requires 3D extensions of indoor applications to support better risk reduction and response strategies. The paper highlights the need for assessment and explores the role of 3D geospatial information and modeling regarding the indoor structure and navigational routes which can be utilized as disaster risk reduction and response strategy. The reviewed models or methods are analysed testing parameters in the context of indoor risk and disaster management. These parameters are level of detail, connection to outdoor, spatial model and network, handling constraints. 3D reconstruction of indoors requires the structural data to be collected in a feasible manner with sufficient details. Defining the indoor space along with obstacles is important for navigation. Readily available technologies embedded in smartphones allow development of mobile applications for data collection, visualization and navigation enabling access by masses at low cost. The paper concludes with recommendations for 3D modeling, navigation and visualization of data using readily available smartphone technologies, drones as well as advanced robotics for Disaster Management
Disaster management: An integral part of science & technology system and land administration management system
Disaster management is a multidisciplinary field, which requires a general coordination approach as well as specialist approaches. Science and Technology system of a country allows to create policies and execution of technical inputs required which provide services for the specific types of disasters management. Land administration and management agencies, as the administrative and management bodies, focus more on the coordination of designated tasks to various agencies responsible for their dedicated roles. They get help from Scientific and technical inputs & policies which require to be implemented in a professional manner. The paper provides an example of such integration from India where these two systems complement each other with their dedicated services. Delhi, the Capital of India, has such a disaster management system which has lot of technical departments of government which are mandated to provide their services as Emergency Service Functionaries. Thus, it is shown that disaster management is a job which is an integral part of Science & Technology system of a country while being implemented primarily with the help of land administration and management agencies. It is required that new policies or mandates for the Science and technology organizations of government should give a primary space to disaster management3D Geo-Informatio
Data consistency checks for building a 3D model: A case study of Technical University, Delft Campus, The Netherlands
GIS is changing rapidly its face with the advancement of computing technologies. From merely a 2D representation of real world features, it is moving to present more and more applications in 3D formats. Today 3D GIS is an essential way of handling the spatial data in urban planning. In cities where every inch of land is measured and is consumed by construction of buildings, mere 3D visualisation of the features is not enough. For certain applications which require extensive details of the building architectures, it becomes a prerequisite to maintain a topological accuracy among the features to be represented. This paper describes the process of topologically correcting 2D features to serve as the basis to create topologically correct 3D city models. The 3D model is created from an existing 2D large-scale topographic map and LIDAR height data.OTB OnderzoekOTB Research Institute for the Built Environmen
Early low-temperature responsive mitogen activated protein kinases RaMPK1 and RaMPK2 from Rheum australe D. Don respond differentially to diverse stresses
Rheum grows luxuriantly in a niche of low
temperature (LT) at high altitudes in Himalayan belt. The
plant is expected to harbor novel genes particularly for tolerance
to LT. Using differential display, two cDNAs
RaMPK1 and RaMPK2, showing homology to mitogenactivated
protein kinases (MAPKs) were isolated. As compared
to RaMPK1, RaMPK2 exhibited strong up-regulation
in response to LT. RaMPK1 was novel in terms of possessing
a small glutamine and proline rich region at the
N-terminal end. Secondly, though RaMPK1 showed
homology with salicylic acid (SA) responsive MAPKs, the
gene was down-regulated by SA but activated by jasmonate
(JA). Abscisic acid (ABA) and polyethylene glycol (PEG)
also down-regulated RaMPK1. RaMPK2 showed downregulation
within 5 min of exposure to JA and SA treatments,
followed by gradual increase in expression. Expression
of RaMPK2 was wavy in response to ABA and PEG
treatment. Results are discussed in light of the novelty of
these MAPKs

3D Cadastres in India: Examining the status and potential for land administration and management in Delhi
Urbanization and the trend towards complex infrastructure development challenges the traditional two-dimensional (2D) cadastral representations used in conventional land administration. Three-dimensional (3D) representations are argued to serve as the future basis upon which to spatially define rights, restrictions and responsibilities (RRRs) in these environments. In Delhi, the capital city of India, where horizontal expansion via new settlements in peri-urban areas, and vertical expansion by densification of city infrastructure, are both prevalent, the need to manage this increasingly complex 3D infrastructure environment presents a great challenge for land administration and management agencies. This paper explores both the current and potential future application of 3D representation in Delhi, with respect to land use planning, development and management. A cross-cutting thematic case study analysis is undertaken: policy drivers, legal frameworks, organizational aspects, and technical standards are considered. For each aspect a separate analytical approach is used. Based on the results, it is concluded that current practices related to 3D representation are somewhat immature and not adequate for capturing the future vertical growth of Delhi. This could lead to legal and physical boundary inconsistencies and irregularities, and dispute cases. However, by learning from international developments and standards-based approaches, agencies have the potential to enhance and support processes in their respective land administration systems. To realize this potential, internal and external policies, institutional settings and, technical and financial arrangements need to be reformed. In the short term it is recommended to focus on raising awareness for the widespread adoption of 3D representations in relevant agencies in Delhi
Integrated flood disaster management and spatial information: Case studies of Netherlands and India
Spatial Information is an integral part of flood management practices which include risk management & emergency response processes. Although risk & emergency management activities have their own characteristics, for example, related to the time scales, time pressure, activities & actors involved, it is still possible to identify at least one common challenge that constrains the ability of risk & emergency management to plan for & manage emergencies effectively and efficiently i.e. the need for better information. Considering this aspect, this paper explores flood management in Netherlands& India with an emphasis on spatial information requirements of each system. The paper examines the activities, actors & information needs related to flood management. Changing perspectives on flood management in Netherlands are studied where additional attention is being paid to the organization and preparation of flood emergency management. Role of different key actors involved in risk management is explored. Indian Flood management guidelines, by National Disaster Management Authority, are analyzed in context of their history, institutional framework, achievements and gaps. Flood Forecasting System of Central Water Commission of India is also analyzed in context of spatial dimensions. Further, information overlap between risk & emergency management from the perspectives of spatial planners & emergency responders and role of GIS based modelling / simulation is analyzed. Finally, the need for an integrated spatial information structure is explained & discussed in detail. This examination of flood management practices in the Netherlands and India with an emphasis on the required spatial information in these practices has revealed an increased recognition of the strong interdependence between risk management and emergency response processes. Consequently, the importance of an integrated spatial information infrastructure that facilitates the process of both risk and emergency management is addressed.OTBArchitecture and The Built Environmen
