MGCP Topographic Dataset

The Multi-national Geospatial Co-production Program (MGCP) is a coalition of over 30 countries dedicated to producing high-resolution topographic vector data throughout high interest areas of the world. Data is extracted from high resolution imagery in 1° x 1° cells at a scale of 1:50 000. All data produced must meet a minimum horizontal circular error accuracy of 25m and meet MGCP Technical Reference Documentation (TRD) specifications, which details extraction guidelines and feature catalogues to ensure consistency. Cell and subregion metadata delivered in XML files based on ISO standards 19115 for geographic content and 19139 for XML implementation is available for the data.

Data: boundaries and markers, hydrography (rivers, lakes, waterfalls,…), industry, physiography (soil surface, volcano areas,…), place names, population (buildings,…), transportation (roads, runways,…), utilities, vegetation.

多国地理空间协同生产计划（MGCP）是由超过30个国家组成的联盟，致力于全球高关注度区域的高分辨率地形矢量数据的制作。数据通过1° x 1°的单元格，从高分辨率影像中提取，比例尺为1:50,000。所有生成数据必须满足至少25米的水平圆形误差精度要求，并符合MGCP技术参考文档（TRD）的规定，该文档详细阐述了提取指南和特征目录，以确保数据的一致性。基于ISO 19115地理内容标准和19139 XML实现标准的XML文件中包含的单元格和子区域元数据可供数据使用。
数据：边界和标记，水文（河流、湖泊、瀑布等），产业，地形（土壤表面、火山区域等），地名，人口（建筑物等），交通（道路、跑道等），公共事业，植被。
