To demonstrate how easy it is to combine data from multiple sources into one map, let’s walk through an example. Say you’re using Surfer and have an aerial photo from Google, a DEM from the USGS, and drillhole data you’ve collected yourself. In this situation, you’d import all of...
When you just want physical prints, you can visit theUSGS storeto get them delivered at a cost. Overall, the natural and physical landscapes in the USGS topo maps have become an extremely valuable base map source of data. Check out these sources and see for yourself....
The Lidar data is in UTM meters and my CAD drawing is in Minnesota state plane feet. I can create surfaces using the Lidar DEM files, but I'm having trouble re-projecting and converting the elevations from meters to feet. I can re-project using ArcMap, but I don't have the spatial...

All I had to do was return USGS data, process it into an array of coordinates and then move the camera from point-to-point along that path until it hit its destination. Simple, right? Not quite, early iterations of the project ended up as incredibly bumpy rides (if you’re prone to ...
Some file import, map display, and geometric geodesy UI functions have been removed Errors File Import UI Functions • The demdataui function has been removed. Use the readgeoraster function instead. • The vmap0ui function has been removed. Use the vmap0read function instead. Map Display...
Data Collection– Sentinel-1, Sentinel-2, Sentinel-3, Sentinel-5P, DEM Layers– True color, false color, NDVI, SWIR, land cover classification, etc. It’s a really nice feature to be able see for yourself what the imagery will look like before you download it. This is a big improvement...
Two DEM data sources include: 1/3rd arc-second (10 m) National Elevation Dataset (NED) produced by USGS; 1 arc-second (30 m) global ALOS AW3D30 Digital Surface Model produced and distributed by the Japan Aerospace Exploration Agency; Both elevation rasters can be considered to represent ...
(2019b) recently proposed Version 4.0 of Fmask to enhance the cloud detection for Landsat data by integrating a Digital Elevation Model (DEM) to normalize the Cirrus Band. However, omission and commission errors of cirrus clouds were still observed. Cirrus clouds are abundant in the atmosphere (...
Where to get SRTM3? There are many versions of SRTM3. I got them from hereftp://srtm.csi.cgiar.org/SRTM_v41/SRTM_Data_GeoTIFF/(可用,亲测) (there where some tiles broken but owners claim they have fixed them already). 原文链接:How to configure SRTM elevations in WorldWind WMS...
