Apr 4, 2020 The DEM has 1 arc-second latitude and longitude postings (~30 m) and employed cloud masking to avoid cloud-contaminated pixels. Custom
1/27" = 1 m If you report a position to the nearest 0.01° (two decimal places for latitude and longitude), you will only be accurate to around 1 km. While this is adequate for rough locations on a global scale, for detailed work it will be inadequate.
So 1 arc second of a 1 foot diameter circle is equal to .000029 inches. (12 * PI inches diameter divided by (360*60*60)) LiDAR-based elevation rasters from the National Map are 1/9 arc-second products (about 3-meter resolution) while elevation based on 10-meter USGS DEMs are 1/3 arc-second products. There may be 1/9 arc-second National Map elevation products that are not based on LiDAR (metadata should described source of particular data). 2021-03-01 · SRTMGL1 coverage now includes Africa, Europe, North America, South America, Asia, and Australia in 1° X 1° tiles at 1 arc second (about 30 meters) resolution. This is the third release in the series providing access to additional NASA SRTM Version 3.0 Global 1 arc second (SRTMGL1) data coinciding with areas released by the USGS. 2017-09-13 · From meters to feet, input a constant value of 3.2808399, the conversion factor for meters to standard or international feet, in the other input field.

DEMs at 5 meters, 1/3 arc-second, and 1/9 arc-second maps are also used where available. This is a download of the NED 1/3rd-arc-second (approx. 10m). Elevations are in NAVD88 meters, with geographic (lat/long) horizontal coordinates. These data are current as of 4/26/2012, The National Elevation Dataset (NED) is a seamless raster product primarily derived from USGS 10- and 30-meter Digital Elevation Models (DEMs). Converting units. The Units Conversion tool converts elevation and depth attribute values stored in feet and other units to meters.

This is a tiled collection of the 3D Elevation Program (3DEP) and is 1 arc-second (approximately 30 m) resolution.The elevations in this Digital Elevation Model (DEM) represent the topographic bare-earth surface. The 3DEP data holdings serve as the elevation layer of The National Map, and provide foundational elevation information for earth science studies and mapping applications in the

Solution : also use the small angle formula. 1 arc-min = 60 arc sec. We want distance d, knowing that a = 60" and D = 2 mm = 2 x 10-3 m . Conversion to meters
1/3rd Arc-second Digital Elevation Models (DEMs) - USGS National Map This layer of the National Elevation Dataset (NED) is 1/3 arc-second (approximately 10 m) resolution. The1/3 arc-second NED are derived from diverse source data that are processed to a common coordinate system and unit of vertical measure. 2007-03-12 · o 1 arc second (30 meter) posting DEM o 1/3 arc second (10 meter) posting DEM o 1/9 arc second (3 meter) posting DEM Advantages o Most edge matching / seam issues from quad based DEMs have been fixed o 1/3 arc second NED provides very close fidelity to quad contours o Avoids many of the problems in original 30 meter DEMs. I'm using ArcMap 10 and have 1 arc-second, 1/3 arc-second, and 1/9 arc-second DEMs. I understand that 1/9 arc-second is about 3 meters, 1/3 arc-second is 3-Arc seconds: SRTM 1-Arc second: world from 56° S to 60° N , except the middle east : Public Domain: 1-Arc second: GTOPO30: world: Public Domain: 30 Arc Seconds: GLOBE: world: Public Domain: 30 Arc Seconds: CGIAR: world from 56° S to 60° N : non comercial: diverse: MERIT DEM: world from 60° S to 90° N: non comercial: 3-Arc seconds How to convert Gons to Second Of Arc (gon to SOA)? 1 gon = 3239.999818487 SOA. 1 x 3239.999818487 SOA = 3239.999818487 Second Of Arc. Always check the results; rounding errors may occur. Definition: The gon, also called grade, grad, or gradian, is a unit of plane angle, equivalent to 1⁄400 of a turn, 9/10 of a degree, or π/200 of a radian.
