In order to improve the synchronization efficiency of the high-capacity agriculture spatial data in the wireless network, a new 4-tuple synchronization model (MCOD) is proposed. The model represents the relationships among the atomic change types, synchronized data, synchronized operations and synchronized metadata. In this work, a new typology with 11 atomic change types of the agricultural features...
SVGT which is based on XML is one of suitable map formats used in Mobile GIS. However, the tags used in SVGT are still the large amount of data. Moreover, there is no existing SVGT map for applications often. To bridge the MapInfo map and SVGT, this paper presents a compact mobile map format called SSVGT, which simplifies the representation and process of map data for mobile devices. SSVGT exploits...
