Abstract: The present invention relates to a method for visualizing a disaster situation in a clear manner within a grid system by converting a lot of spatial data related to disaster safety, such as, building space information data and other Excel-based data into geocoding and location-based data. When disaster safety-related information flows into a computer, a spatial data visualization program built into the computer is executed to convert data into geocoding and location-based data. Thus, in a method of visualizing a disaster situation based on a grid system map which is clearly expressed in a grid system on a monitor, the disaster safety-related information is visualized as a disaster risk analysis map through a geocoding process and a grid spatial information conversion process. The geocoding process is a process of spatially joining them based on an attribute after geocoding the building geospatial information data and Excel-based data to convert the collected information into new grid space system data. After a lot number and a new address are extracted from address-based Excel data, the lot number and the new addresses are converted into a Parcel Number (PNU) code. In addition, basic spatial information PNU field is checked and joined with a table using a PNU value, and then checking data. Regarding the grid spatial information conversion process, the joined figure data is organized. After property maintenance such as year of completion, classification by property, and integration by grid, a Null grid is deleted and a total floor area of a building is calculated for each grid, so a center point of the building is extracted. Moreover, data for each grid is spatially joined to complete grid data.
