Aerial render of the Build The Earth project on a modified Airocean World Map. Build the Earth was created by YouTuber PippenFTS in March 2020 as a collaborative effort to recreate Earth in the video game Minecraft. [1] During the COVID-19 lockdowns, the server aimed to provide players with the opportunity to virtually experience and construct ...
The use of JPEG is discouraged, since it is a lossy compression format and so will result in a blurry map or diagram. The quality of GIF images is better than JPEG. GIF images allow for the creation of animations. PNG is a lossless, truecolor image format. It is good for all maps and particularly for maps with more than 256 colours.
The generic meaning of the six parameters in a world file (as defined by Esri [1]) is: Line 1: A: pixel size in the x-direction in map units/pixel; Line 2: D: rotation about y-axis; Line 3: B: rotation about x-axis; Line 4: E: pixel size in the y-direction in map units, almost always negative [b] Line 5: C: x-coordinate of the center of the ...
National Transfer Format (NTF) – National Transfer Format (mostly used by the UK Ordnance Survey) Shapefile – open, hybrid vector data format using SHP, SHX and DBF files (by ESRI) Spatial Data File – high-performance geodatabase format, native to MapGuide (by Autodesk) TIGER – Topologically Integrated Geographic Encoding and Referencing
The shapefile format is a digital vector storage format for storing geographic location and associated attribute information. This format lacks the capacity to store topological information. The shapefile format was introduced with ArcView GIS version 2 in the early 1990s. It is now possible to read and write geographical datasets using the ...

The Geospatial Data Abstraction Library (GDAL) is a computer software library for reading and writing raster and vector geospatial data formats (e.g. shapefile), and is released under the permissive X/MIT style free software license by the Open Source Geospatial Foundation.
