Map Projections

If you are primarily interested in buying a map for decor purposes then, the main thing to know is that a map projection determines the shape of the map, just as map style determines the color scheme of a map.

Map Styles explained

All of our satellite imagery maps are derived from one very large whole-world image or another, also known as the source image. Each of these very large source images consists of data from specific satellites, specific image capture instrumentation, a time period over which the data was collected etc.

Buying a map for decor
For aesthetic purposes it is enough to know that these different source images (and the maps derived from them) have different color palettes. For that reason we refer to them as different "styles". We currently carry two styles, namely "New Generation Winter" and "Spectrum World".

Buying a map for reference purposes
Since these satellite imagery maps are cartographically correct, accurate and the data is of very high resolution, they can be used for reference and educational purposes. The source images are seamless mosaics of cloud-free satellite scenes that are geo referenced. Some source images incorporate bathymetry data (topography of the ocean floor) from various surveys and occasionally data from different satellites.

Spectrum World style (MODIS and GEBCO data)

Spectrum WorldThe land cover imagery was collected using NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) in August 2004. Ocean bathymetry is derived from the RAMP II dataset (Radarsat Antarctic Mapping Project Digital Elevation Model), Version 2, 2001 and GEBCO (General Bathymetric Chart of the Oceans), 2003. Polar sea ice is based on a combination of sources including MODIS data and observations of Antarctica made by the National Oceanic and Atmospheric Administration's AVHRR sensor (Advanced Very High Resolution Radiometer).

New Generation WinterNew Generation Winter style (MODIS winter data)

The land cover imagery was collected using NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) in February 2004. Polar sea ice is based on a combination of sources including MODIS data and observations of Antarctica made by the National Oceanic and Atmospheric Administration's AVHRR sensor (Advanced Very High Resolution Radiometer).
