Standardizing the mathematical basis of spatial data in the construction of a pilot urban GIS database in Soc Trang province

Abstract

Building a GIS urban database plays an important role in the process of developing smart cities. To have a complete urban database that contains a lot of information in many fields, it is necessary to collect data from many different sources. Information from many different sources must be standardized, in which spatial data must ensure the required mathematical basis. This article introduces a method of standardizing spatial data in coordinate form based on conversion parameterscasestudy in buildingplanning database of Soc Trang province. Themethod in this article brings high accuracy, economy, and supports the management of updating data into big data.
