The USGS DEM standard is a geospatial file format developed by the United States Geological Survey for storing a raster-based digital elevation model. It is an open standard, and is used throughout the world. It has been superseded by the USGS's own SDTS format but the format remains popular due to large numbers of legacy files, self-containment, relatively simple field structure and broad, mature software support.
A USGS DEM can be classified into one of four levels of quality. This is due to the multiple methods of data collection, and certainty in the data.
The USGS DEM format is a self-contained (single file) set of ASCII-encoded (text) 1024-byte (1024 ASCII chars) blocks that fall into three record categories called A, B, and C. There is no cross-platform ambiguity since line ending control codes are not used, and all data including numbers is represented in readable text form. There is no known binary analogue of the format, although it is common practice to compress the files with gzip.
Demai (Hebrew: דמאי) is the third tractate of Seder Zeraim ("Order of Seeds") of the Mishnah and of the Talmud. There is some debate as to the literal meaning and origin of the word. It is concerned mainly with laws related to produce where it is suspected that ma'aser rishon (the first tithe for the Levi), terumat ma'aser and ma'aser sheini (the second tithe) or ma'aser ani (the tithe for the poor), depending on the year of the Shemittah cycle, have not been properly separated in accordance with Num. 18:24-28. It consists of seven chapters and has a Gemara from only the Jerusalem Talmud.
DEM was the ISO 4217 currency code for the Deutsche Mark, former currency of Germany.
