چکیده
National administration of surveying, mapping and geoinformation started to launch the project of national fundamental geographic information database dynamic update in 2012. Among them, the 1:50000 database was updated once a year, furthermore the 1:250000 database was downsized and linkage-updated on the basis. In 2014, using the latest achievements of 1:250000 database, comprehensively update the 1:1000000 digital line graph database. At the same time, generate cartographic data of topographic map and digital elevation model data. This article mainly introduce national 1:1000000 cartographic data of topographic map, include feature content, database structure, Database-driven Mapping technology, workflow and so on.

An Investigation on Selecting Cartographic Scales on Sediment Delivery Ratio in Jamash Watershed
Multicipality inputs of different analysis of digital data in modern methods of map processing causes the changes in results of erosion and sediment models. In this context, selecting a cartographic scale as the major input of spatial data has become a challenge issue in erosion and sediment modeling. Therefore, in this study, using topographic maps and selecting to spatial scales (1:25000 and ...

From now on, the French National Mapping Agengy (IGN France) is set up with the BD TOPO®. This is a topographic vector database that covers the whole national territory. IGN has decided to product base maps at 1:25k and 1:50k from this database. On topographic mountain maps, rocks areas are among the most difficult map elements to represent, dealing with digital cartography. In the past, they w...
متن کاملCartographic and Topographic Mapping of the Icy Satellites of the Outer Solar System
Cartographic and topographic mapping of the major satellites of the Outer Solar System has been in progress since the late 1980’s, beginning with Voyager image data, and incorporating Galileo and recently Cassini imaging data as released to the public. Global image mosaics, based on cartographic control nets, have been produced for all these satellites. In addition, digital topographic maps hav...
متن کاملMethods to Measure Map Readability
Several countries are currently working on setting up geoportals as part of their national spatial data infrastructure (SDI). A key ability of these geoportals is that the user should be able to view (and download) data from several sources from one access point. This will certainly make the access to geospatial data easier. However, there is also a cartographic challenge that has to be solved....
