Progressive transmission represents an effective means for the transmission of spatial data over the web. We classify current implementations of this paradigm as either view- or scale-based, which transmit data in a manner which is a function of the required map region or scale respectively.
Transmitting vector data over the Web is a challenging issue. Existing methods for vector delivery over the Web focus on progressive transmission techniques. Long standing problems in the formalization of dynamic generalization and the time needed for complex...
20 Ιουν 2011 · This chapter provides a critical overview of these issues and of the few prototype systems that have been described and developed for progressive vector map transmission.
In this paper we propose a novel methodology for progressive transmission which overcomes this dif-culty. Results demonstrate that signi cant reductions in the amount of data transmitted are ...
1 Ιαν 2007 · This paper proposes and implements a new methodology for progressive transmission of vector lines and polygons over the Internet. The methodology generates continuous vector data through ...
This paper proposes a new progressive transmission with quadtree in order to improve progressive transmission of an image in two viewpoints of bitplane and spatial transmission, in addition to compression efficiency.
1 Σεπ 2017 · In order to improve the performance of web-based GIS application for vector data, the approach of progressive selection and transmission is an effective way, and a feature selection is an essential method towards progressive vector transmission.
