Aesthetics 3D Geovisualization For Flood Disaster Based on XYZ Coordinate

Abstract

Geovisualization can convert spatial and non-spatial data into an accurate visualization of flood modelling but less realistic. Contrarily, Multimedia can produce realistic visualizations by applying aesthetic parameters, but not based on data, inaccurate. This research successfully combined both Geovisualization and Multimedia that created an accurate and realistic visualization of flood modelling. An experimental methodology was used for the flood transformation data through geovisualization technique and carried out the 3D mapping objects through photogrammetry by using drones. Both modellings were combined by overlapping the X, Y, Z coordinates. Multimedia techniques were used to remodeling, animate, design interface, action script, and to apply aesthetic parameters. The success of this study was measured through a comparative evaluation; comparing between the model of this research, and two other models from previous studies. The result was 84.6% of the respondents chose this research modelling. The researcher used Alpha Cronbach's reliability test with SPSS for validity checking. The result showed a significant reliability value of 0.935. In the theoretical contribution, this research modelling produced visualizations of flood modelling based on accurate data and aesthetic values. While in practical contribution, this modelling can be used as a source of information for the decision-makers for flood mitigation plans.
