Hi All-
Is anyone aware of any 1-arcsecond SRTM elevation data available for S.E. Peru, particularly in Madre de Dios? Are there any other sources, such as ERS In-SAR (20 meter) for that area of interest?

1 arcsecond SRTM is only available for the US, so for Peru you'd have to work with the 3 arcsecond data, or find an alternative source.

Thank you for your reply.

Tom,

To clarify a bit, the data is there: it is just classified, therefore "unavailable." You may submit a petition (FOIA) under these terms.

However, my experience tells me it's a long, tough road to traverse (which usually is a dead end), particularly if a published product is your end result. Your best bet is to request the result you need (ie. shaded relief image) instead of trying to obtain the elevation data since it's the DOD's paranoia that you're trying to allay. You never know when and where they're going to cave. Public access to once classified data is becoming more and more common. This may especially be true since the US currently maintains fair relations with Peru. Perhaps with the blessing of their Embassy, who knows...?

Have you looked at national sources? The Peru national land survey... ?

it's a worth to have a look:
