SDTS Raster to Grid Conversion in ArcGIS 10

[KenLucas]

Hi, fellow scroungers of online data,
    The SDTS Raster to Grid Conversion command button, available in arc 9.3 allows us to convert the digital elevation model data, available online from the US Geological Survey gis data website. The DEM data converted to grid, with the command button, can then be processed, by spatial analyst tools, to make contour lines. I can not find this conversion command button in the customize commands list for GIS 10.0.  How is this conversion is being done by users of Arc 10.0?

I don't think there's a downloadable trial of ArcInfo Workstation. However, the ArcGIS for Desktop trial includes the Data Interoperability extension which says it supports SDTS as an import format.

SDTS rasters are also supported out-of-the-box so just try adding the SDTS data to ArcMap.

Disclaimer: I'm going by help documents, so my answer may not be correct!
