Abstract

The invention discloses a cross-media electronic document technology platform supporting spatial data. The cross-media electronic document technology platform comprises a MapPDF editor and a MapPDF reader and is characterized in that the MapPDF editor is used for embedding MXD maps exported from ArcGIS into a PDF file to generate a Map PDF map file; the MapPDF reader is used for browsing the Map PDF file; the technology platform uses the Geospatial PDF standards to build data models and uses the GeoPackage standards to build map information packets, and the map information packets are used forstoring multi-dimensional heterogeneous spatial data. The cross-media electronic document technology platform has the advantages that the Geospatial PDF standards and the GeoPackage standards are adopted, the cross-media feature of PDF is utilized, the spatial data, application logic, mapping information and printing and publication information are integrated, and the limitation of a traditionalelectronic map on usability, portability and readability is well solved.

Description

technical field [0001] The invention relates to a map visualization tool. More specifically, the invention relates to a cross-media electronic document technology platform supporting spatial data. Background technique [0002] With the rapid development of visualization technology and network technology, map visualization has greatly expanded both in the medium it uses and in the field of application. New forms of maps have emerged one after another, and the functions of maps have also been greatly expanded. At the same time, the visualization technology of digital maps has also promoted the deepening of map representation methods, and has made major breakthroughs in describing geographical environments and explaining objective laws compared with traditional maps. [0003] Different forms of maps rely on different media. Generally speaking, the media for map dissemination can be divided into three categories: printed media (mainly refers to flat paper), electronic media (m...
