A Standardization Perspective towards the In-teroperability of Temporal Information – An Ex-ample of Land Administration Domain Model

Abstract

GIS is used for modeling the dynamics of earth phenomena Geographic data is therefore the recordings of chosen applications at a specific time regardless of whether the time information is recorded As time changes their positions shapes or attributes may change Due to the lack of agreement on how temporal information is presented and recorded how to deal with the heterogeneous design of time aspects from data collected by different domain stakeholders becomes a critical issue Users processing the data without knowing the correct time may cause the analysis results to be meaningless and even totally wrong decisions If there is no standard of time record a large amount of data will not be able to exert its application value The focus of this study is to develop a standard temporal-based model so as to correctly record and determine the valid time range of the data description status in each domain automatically make it have a time quality description The main method is to propose a decision tree which decided by four-phase design workflow with semantic considerations summarize ten phenomenon descriptions All scenarios are designed with specific time attributes and develop the overall structure of service sharing explore the topology and effective operation mode of temporal data and finally through the integration and application of cross-domain data to verify the feasibility of this framework According to the standardized temporal record framework proposed in this paper the LADM profile can be more flexibly applied to Taiwan cadastral management effectively controlling the description of historical states and the relationship between different versions
