ASTER Global Digital Elevation Model (ASTER GDEM)

**Qui najua** · 2020-03-17, 11:24 PM

Now you can easily create and obtain a global digital elevation map (ASTER GDEM).With the help of the global mapper it is possible to create usage maps for Atoll.
A DEM data which is acquired by a satellite-borne sensor "ASTER" to cover all the land on earth.
Easy-to-use topographic information of the global terrain.

This is a global digital elevation map - resolution 30 meters. Do you have a resource - for a resolution of 5 meters?

I am interested in the Caucasus at a resolution of 5 meters.
Is there such an opportunity, with a resource of 5 meters?

Can you explain that a bit more in detail?

I am new to mapping, I am trying to find/create a map of the Netherlands for use in Atoll.

Good afternoon!
Dear Dmitry!
The quality of the document that is uploaded to https://www.4shared.com/img/XgnTzs6n...or_Coverage_Pr is very poor.
Can I upload a document in good quality so that I can examine the contents?

Hi Slava,

Thanks for the offer, I managed to use GlobalMapper and ASTER GDEM v2 to at least get the elevation data into Atoll.

However, I noticed something strange in the ASTER data: it looks like "holes" on the image:

ASTER_v2_holes.zip

(I put the image into a zip as the forum engine resizes every PNG or JPG image to useless resolution),

And if I use the above map area, in Atoll it is quite clear that those "holes" are affecting the coverage projection.

The same "holes" are not there with the "SRTM Worldwide Elevation Data", but the resolution of the later is not that great (although they both should be 1 arc second resolution.

Am I doing something wrong? Or these "holes" are really errors in the map data?
