The Online Map Creation (OMC) Utility
Entry ID: Online_Map-OMC-00
Summary
Abstract:
(Summary adapted from the Internet Scout Project Volume4, Number5,
October 25, 2000) Online Map Creation (OMC) is a resource for geologists, geographers, or anyone needing to make a map figure for a research paper or conference talk. Here you can create Postscript-formatted maps of just about any locality by inputting geographical coordinates. OMC is a subset of GMT (Generic Mapping Tools) ... ![]()

Quality
Known bugs: Plotting maps with topography and/or bathymetry
contours with a Lambert Azimuthal projection results in a map where only the area specified in the input form gets the contours. Performance of OMC depends on internal processing time and ratio in a given situation. Internal processing (map generation, postscript ... ![]()
Use Constraints
The OMC offers the plotting of contour lines for bathymetry
(water depth) and topography (elevation of dry areas). The information used are derived from the ETOPO5 data set which is available from U.S. National Geophysical Data Center (NGDC). E. S?ding of GEOMAR made a global GRD-file from ETOPO05 and allowed us to use this with OMC. Here this data set is only used to illustrate the relief of the area mapped: the contours are not annotated. The deviation of the contours from the "real world" might reach tens to hundreds of meters. It is not intended to give serious morphological information (e.g. for navigational purposes).
