Small areas of a 1:1,000,000-scale map, entitled Ministerio de Guerra Mapa Fisico Politico del Peru, produced in 1984, were adapted for digitizing to fill gaps in source data for South America. The map had a contour interval of 1000 meters. Digitizing was done by the Geographical Survey Institute of Japan.

USGS used ANUDEM-based contour-to-grid techniques to create DEMs from these digitized map areas. That procedure is described in Section 5.A.vii.

Plate 29 has broad peaks and sharp spikes at increments of 1000m, with a subsidiary peak/spike at 500m, and few values below 400m. The latter is consistent with the coverage of this data set, which includes no coastal areas.
