It is important to compare and analyze alternative geocoding techniques since the requirement for exact location data in a variety of areas, including emergency response, urban planning, and geographic information systems (GIS), keeps developing. The precision of cadastral maps, once aligned with topographic mapping standards, has seen advancements over time. However, due to the fragmented compilation process, the accuracy of these maps can vary significantly across large regions. The study aimed to compare the positions of addresses identified on Google Maps with those derived from lot parcel data in Arau, Perlis. The objectives were to create a comprehensive database for geocoded addresses and to evaluate the accuracy of these geocoded addresses against their corresponding positions on Google Maps. The problem statement highlighted that while cadastral maps had historically maintained high accuracy, improvements over time and a fragmented compilation process led to significant variations in accuracy across large regions. The methodology involved collecting geocoded addresses and lot parcel data, developing a database, and conducting a comparative analysis using spatial statistical methods to assess discrepancies and accuracy levels between the two datasets. The results indicated varying degrees of accuracy between the geocoded addresses and the Google Map positions, revealing areas where cadastral map improvements were necessary. Findings for this study were, there were 95% matched address, 5% tied and 0% unmatched. The study concluded that, although Google Maps provided a reliable source for address positioning, there were notable discrepancies when compared with lot parcel data. These findings underscored the need for continuous updates and integration of geospatial data to enhance the accuracy and reliability of cadastral maps, ultimately aiding in better urban planning and land management in Arau, Perlis.
