SRTM Interpolation Trial Version

Question

Hey guys

I'm new to ArcGis and the general topic geo data.

I came to ArcGis because I need to interpolate the 90m SRTM data (Europe) and I found this post. I want to use the data later in a game I'm developing.

So I just downloaded the trial version of ArcGis and clicked a little bit through the Applications (ArcGlobe, ArcMap, ArcScene). But I can't find ArcGIS Spatial Analyst which was mentioned in the old post.

So is it possible to perform the SRTM interpolation with the trial version? If so, how can I do it?

Thanks for help and replies

from the help files on SRTM which means that you need to use arcobjects

Supported raster formats

So you will have to examine that documentation

Mission (SRTM)

The HGT format is used to store elevation data from the Shuttle Radar Topography Mission (SRTM). SRTM-3 and SRTM-1 v2 files can be displayed.

Single file—extension *.hgt

Read-only (Write—developer only

Thank you for that tip 
 I resampled data from 90m to 30m, but how can I save the resampled data as .hgt again?

SteveLynch · Answer

You could simply use the Resample (in Data Management) tool and choose bilinear interpolation.
