In this video, we show you how to extract contours using Google Earth, GPS Visualizer, and QGIS and how they compare to contours created from lidar data. We use the Equator platform to source free, public lidar data in the US and generate contours directly from the information on the fly.

We are constantly making improvements to our user interface. If the UI in this video doesn't match the current UI of the Equator platform, watch our latest video on extracting data from Equator's newest interface: kzfaq.info/get/bejne/hc2paaleq8nekZc.html

Amazing. I will be using similar visualizations for drone survey vs goog earth resolution in a digital portfolio format. But I will have to include a video presentation. You did this so well.

WOW! I'm not completely following what you're doing here, but I've been very interested in maps, topo, and lidar. I just searched you tube to see if there's anything I don't know, and obviously there is! Oddly enough the spot you zoomed into is 2 counties north of me in Iowa! On the site I use we just got 2020 lidar color hillshade for my area, which is awesome! It picks up my ATV trails through the timber, even logs lying on the forest floor. I use the maps to help with farm maintenance and also help in my hunt for arrowheads. And it's just neat to explore places I normally wouldn't be able to go.

good afternoon. Can this technique be used to study the shores of the seas and lagoons? I am interested in the height and slope of the coast. Thanks

Hi, first time to see equator app, just asking is it free and is it cover the entire world? Bcoz sometimes it's only in the US.... thanks

@equatorstudios 2 жыл бұрын

You can access 30 m DEM data anywhere in the world using Equator. The high-resolution lidar is only in the US, some parts of Canada, and New Zealand. Some aspects of the platform are free and other's are paid. You can try everything out for free though!

How can I get an elevation profile/cross section like you show in Excel from geotiff LIDAR data?

@equatorstudios Жыл бұрын

Once you have a LiDAR file imported onto the map, use the cross section tool on the right-hand toolbar. Then, after the profile is drawn, click 'view cross section' in the menu on the left.

Okay, im trying to do this but im having issues at the 2:00 when it comes to contour.

@elizabetev3780 4 ай бұрын

did you find a way? Struggling with the same

@equatorstudios 2 ай бұрын

QGIS has changed their interface and tools in the latest versions. An alternative to the Vector > Contours option is to use the Contour plugin.

Is that lidar data available for Africa? Good presentation.

@equatorstudios 8 ай бұрын

Currently, we only have JAXA data available for Africa, which is 30m resolution.

using qgis 3.36.1 under vector tab cannot find contour

@equatorstudios 2 ай бұрын

In the older version of QGIS, the Contours is under the Vector tab. This is not available in the more recent versions, so an alternative method would be to us the Contour plugin.

Is it a fee to extract and download contours from a map?

@equatorstudios 16 күн бұрын

Equator offers a free trial that allows you to extract and download contours for a limited number of project locations. After the trial has ended, there is a fee.
