Problems with creation of accurate DEM with S1 images

[ABraun]

@Camaross62

ok ABraun thank you for the answer, I asked you this because a colleague with a computer that has lower characteristics than mine (16GB of RAM, but a processor of only 1.8 GHz) succeeds in the following operation instead. I thought mine was a problem with Java cache memory settings. I will try to do separate the various operations.

Have you incresed the maximum RAM available to Java? It is described in these posts.

• S2 export into tiff - NaturalRGB or Falso color infrared RGB - #5 by marpet
• S1 TOPS Coregistration error - Java heap space error? - #14 by funkenbeachin
• Problem creating image from a band - #2 by obarrilero

In case you only need this small AOI, why do you select all bursts in the Split process? You reduce the processing time and the chance of unwrapping errors if you keep the raster as small as possible.

I cannot tell if the conditions are good for the generation of a DEM, this mostly depends on the vegetation cover of your area (which is always bad) and how the interferogram looks like.
