Mairie de Loevenich (), from the Topographic Survey of the Rhineland by Tranchot/Müffling, sheet 57 (published 1806/07).. A map series is a group of topographic or thematic charts or maps usually having the same scale and cartographic specifications, and with each sheet appropriately identified by its publisher as belonging to the same series.
The organizational unit for the NTDB is the National Topographic System (NTS), based on the North American Datum (NAD) 83. Each file (data set) consists of one NTS unit at either the 1:50,000 or 1:250,000 scale. Furthermore, the data is now available by themes within a file. The ground data is depicted through points, lines, and areas.
Sep 29, 2022 · The Topographic Change working group is defining the concepts, practical tools, and design for a national scale mapping and monitoring system that will enable an ongoing nationwide assessment of multi-scale 3D changes in the Earth’s surface, both natural and anthropogenic in origin, and demonstrating its functional capabilities for the ...
The Map Library at the University of Winnipeg is a full depository for Canadian National Topographic Map Series (NTS) maps. We currently have NTS maps for all areas of the country at the following scales: 1:50,000, and 1:250,000 series. We also have older (1st and 2nd edition) NTS maps at various scales NTS Maps – Early Editions.
ICESat-2 ( Ice, Cloud, and Land Elevation Satellite 2 ), part of NASA 's Earth Observing System, is a satellite mission for measuring ice sheet elevation and sea ice thickness, as well as land topography, vegetation characteristics, and clouds. [9] ICESat-2, a follow-on to the ICESat mission, was launched on 15 September 2018 onboard Delta II ...
Non-conforming maps help make the National Topographic System (NTS) more efficient. Generally, non-conforming map sheets can be identified by their irregular lines on the grid; however, some non-conforming 1:250 000 maps are identified by a light/dark pattern of lines and repositioned labels.
