Spherical Cap Complete Bouguer Correction – Processing Methodology
In this article I discuss the Spherical Cap Complete Bouguer Correction for gravity observations and my processing methodology for computing these corrections.
Global DEM and Bathymetry Rendering
Combining multiple raster datasets with MapInfo virtual rasters and MapInfo raster rendering algorithm technology, I have prepared a new visualisation of global terrain and topography that mimics the kind of color scheme used in an atlas.
Large Raster Rendering Performance in MapInfo Pro
MapInfo Pro can render huge rasters and promises to do so in constant time at any scale. But, if you try it, you might run into problems. In this article I want to share some tips for achieving high quality and high-performance rendering of huge rasters.
Comparing the Quality – CGIAR SRTM DEM vs MERIT DEM
In this article I compare two publicly available global scale DEM rasters – CGIAR DEM vs MERIT DEM.
MERIT DEM now available for download in MRR format
The MERIT DEM is a global scale terrain DEM at 3 arcsecond resolution with coverage from 60 degrees South to 90 degrees North. So, it excludes Antarctica but includes the Northern Latitudes, which is a considerable improvement over similar DEM’s derived from Shuttle Radar Topography Mission (SRTM) data. It was developed by Dai Yamazaki at the University of Tokyo.
