GML이 지리 데이터 저장, 전송 및 교환을 위한 사실상의 표준이 되면서 점점 더 많은 지리 데이터가 GML 형식으로 존재하게 되었습니다. 응용 프로그램에서 GML 문서는 많은 수의 자세한 마크업 태그와 많은 양의 공간 좌표 데이터를 포함하기 때문에 일반적으로 크기가 매우 큽니다. 데이터 전송 속도를 높이고 네트워크 비용을 줄이기 위해서는 효과적이고 효율적인 GML 압축 도구를 개발하는 것이 필수적입니다. GML은 XML의 특수한 경우이지만 현재 XML 압축기는 일반 XML 데이터용으로 설계되었기 때문에 GML에 직접 적용하면 효과적이지 않습니다. 본 논문에서는 GML 문서를 효과적으로 압축하기 위한 압축기인 GPress를 제안한다. 우리가 아는 한, GPress는 특별히 GML 문서 압축을 위한 최초의 압축기입니다. GPress는 좋은 성능을 얻기 위해 GML 문서의 고유한 특성을 활용합니다. 실제 GML 문서에 대한 광범위한 실험을 통해 GPress는 압축 비율에서 XMill(기존 최고의 XML 압축기 중 하나)보다 성능이 뛰어나며 압축 효율성은 기존 XML 압축기와 비슷하다는 것을 알 수 있습니다.

Abstract: As GML is becoming the de facto standard for geographic data storage, transmission and exchange, more and more geographic data exists in GML format. In applications, GML documents are usually very large in size because they contain a large number of verbose markup tags and a large amount of spatial coordinate data. In order to speedup data transmission and reduce network cost, it is essential to develop effective and efficient GML compression tools. Although GML is a special case of XML, current XML compressors are not effective if directly applied to GML, because these compressors have been designed for general XML data. In this paper, we propose GPress, a compressor for effectively compressing GML documents. To the best of our knowledge, GPress is the first compressor specifically for GML documents compression. GPress exploits the unique characteristics of GML documents to achieve good performance. Extensive experiments over real-world GML documents show that GPress evidently outperforms XMill (one of the best existing XML compressors) in compression ratio, while its compression efficiency is comparable to the existing XML compressors.
