Cadastral Mapping App Running Smoothly on iPad Pro

The video below features an interactive cadastral property map application running on an iPad Pro developed by TatukGIS customer TSUKASA Consulting in Japan using the TatukGIS Developer Kernel for Delphi + Mobile. The video demonstrates how smoothly DK developed GIS/mapping functionality runs on iOS. The customer also used the DK to compile the same application for macOS.

The dataset featured in the video is composed of SHP format point and polygon layers containing approximately 110,000 polygons representing individual land parcels. The dataset is representative of a mid-sized city in Osaka Prefecture in Japan, though the data visible in the video has been altered (fictionalized) to ensure there is no violation of data privacy.

Like any DK developed application, the app perfectly supports Japanese language characters.
