![]() Ways to Travel: One of the best ways to get from Las Vegas to Antelope Canyon (and to see it) is to take a guided tour. Lower Antelope Canyon can be visited without advance reservations just drive up to the entrance off Highway 98, and you will be assigned a guide (based on availability). There are five separate sections of the canyon each of which can be visited. Advance reservations are highly recommended, as they limit the number of visitors each day. Reservations: Antelope Canyon is on the lands of the Navajo Nation and can only be visited with an official guide as part of a group or private tour. Antelope Canyon is about a five-hour drive from Las Vegas, so if you leave Vegas very early in the morning, you can do it as a day trip and still make it back for a late dinner. where(dem.gt(1900).and(dem.lte(2000)), 17) Map.addLayer(demclass.Located in the Arizona desert, a bit northeast of the Grand Canyon near the Utah border, Antelope Canyon is a spectacular slot canyon natural wonder and a great place to visit in Arizona. In our case, we classify heights between 0–2000 mamsl: // Remap values. (remember that it can never be lower than the resolution of the image). Then we reclassify the heights according to the distance between contour lines. mosaic (): var dataset = ee.ImageCollection(‘JAXA/ALOS/AW3D30/V3_2’) var elevation = lect(‘DSM’) // projection var proj = elevation.first().select(0).projection() var slopeReprojected = (elevation.mosaic(). For ALOS, you should re-project an image tile using a projection of one of the image tiles, rather than using the default projection returned by. Shuttle Radar Topography Mission (SRTM) Basic creation: Option 1įirst, we add the repositories of the image collections that contain the DEM (digital terrain model). In the case of ALOS, it is necessary to reproject an image tile using a projection of one of the image tiles, rather than using the default projection:ĪLOS Global Digital Surface Model “ALOS World 3D of 30m (AW3D30)” ![]() Dataįor this article, I will be using two datasets. ![]() The extraction of contour lines was carried out from the Google Earth Engine platform and QGIS for 3D was visualized, using the Qgis2threejs module. The Google Earth Engine API provides a library of functions that can generate level lines from the global digital models available from the ALOS and STRM projects. Earth Engine hosts satellite images and stores them in a public data archive that includes historical images of the Earth dating back more than forty years. Google Earth Engine is a platform for scientific analysis and visualization of geospatial data sets, for academic, non-profit, commercial and government users.
