Merged Extracted Vector Shoreline

Created from the Cartographic and Geospatial Technology Program’s (CGTP) Extracted Vector Shoreline Series, the Merged Extracted Vector Shoreline is a seamless vector shoreline file designed to provide users a topologically clean shoreline file depicting the Mean High Water line for the continental U.S., Hawaii, Alaska, and U.S. territories.

The main purpose of the Charted Vector Shoreline Project is to provide public access to accurate and current coastline and shoreline data. The project targets scales between 1:10,000 and 1:80,000 with emphasis on the larger scales. Using processes and software designed by the Cartographic and Geospatial Technology Programs (CGTP), the vector data are automatically extracted from the NOAA Nautical Charts.

From each chart, Mean High Water and Mean Lower Low Water lines are extracted as vector lines from the binary raster files used in nautical chart production. The resulting vector high and lower low water lines are derived from the legal depictions on nautical charts for the United States. The resulting line files are checked for accuracy and converted from paper-charted units to geographic positions and imported to the shape file format used in GIS (Geographic Information Systems) applications.

Drones’ 3D printed parts: Sculpteo gets up in the air with Hexadrone

3D Printed Parts for Drones

It’s well known that drones and 3D printing definitely make a good pair. Additive manufacturing technologies allow droning professionals and hobbyists to build their own aircraft. With today’s technology, drones can perfectly match their owner’s needs. Alexandre Labesse, CEO of the French company Hexadrone shared his views on the influence of 3D printing in the […]

Aibot X6 uses Leica Nova MultiStation for accurate geospatial data without GNSS

(Norcross, GA /Kassel, Germany, 1 October, 2014) – At this year’s INTERGEO in Berlin, Leica Geosystems and its sister company, Aibotix, will present a solution for accurate positioning of the Aibot X6 without GNSS. The UAV can be tracked accurately with the Leica Nova MultiStation to define the exact position. Using the Aibot X6 together with the Nova MultiStation can inspect top surfaces of aircrafts in hangars, enabling users to rely on its proven functionality without the support of GNSS. The UAV, equipped with Leica Geosystems’ 360° prism, flies over the aircraft and takes high-resolution images of its surface. This solution helps, for example, to ascertainlightning strikes and effectively document […]
