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

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

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

Spatial dimensions of land administration and user rights over groundwater: Case study of Kerala, India vs. Coca Cola

Supporting the management of rights related to groundwater based on input from hydrogeology software is contributing to bridging the gap between the technical and administrative aspects of groundwater management. The research reported herein is focused on a specific example (or ‘use case’ in UML terminology), resulting from a court action by Kerala State in India, against the Coca-Cola company, on the overexploitation of the local groundwater aquifer. The use case reports on the economic and policy contexts conducing to the establishment of the Coca-Cola bottling plant in Plachimada, and the ensuing court actions, triggered by the local community assembly first, and then by Kerala State authority, on the grounds of the introduction of toxic waste into the groundwater, making the water unfit for human consumption, and the depletion of the aquifer. Considering the specifics of the use case, the ISO/TC211 Land Administration Domain Model (LADM, DIS 19152) is used as a basis for the development of a specialized profile addressing the need to define laws and regulations with proper spatial and temporal dimensions, to represent the rights to groundwater use by the local communities. Two alternative scenarios are reported: the first is based in the consideration that all the different Property parcels are regulated by Private Law; the second, further develops on the consideration of groundwater as a Public Trust, thus regulating private use through the Public Law domain. The modelling here provided goes from a subset of the LADM conceptual classes to more specialized classes, and is reported through the use of class and instance level (object) diagrams. These build on the existing spatial unit package and the legal and administrative profile, demonstrating the flexibility which can be introduced by LADM. Specifically concerning the representation of spatial units, a previously proposed ‘Mixed 2D/3D’ spatial profile is further developed, addressing the needs of the use case. In combination with the ‘Level’ representation of LADM to organize spatial units, it can contribute to an easier reuse of existing, 2D based, land parcels data, into the proposed 3D and time based model architecture. Concluding, the modelling and architectural framework here reported contributes to a more informed decision in the choice of groundwater rights to be made by the law, policy and courts, taking into account societal needs and changes induced by new socio-economic contexts. The resulting institutional setting will be best informed with spatial and temporal data, and the legal solution chosen be it public or private law focused, can be recorded in a system based on the LADM standard; it allows for much flexibility and only a few specific classes need to be added and further specified in order to be implemented. system based on the LADM standard; it allows for much flexibility and only a few specific classes need to be added and further specified in order to be implemented.OTB ResearchOTB Research Institute for the Built Environmen
