  3. Shapefile - Wikipedia

    en.wikipedia.org/wiki/Shapefile

    The shapefile format is a geospatial vector data format for geographic information system (GIS) software.It is developed and regulated by Esri as a mostly open specification for data interoperability among Esri and other GIS software products. [1]

RPF – Raster Product Format, military file format specified in MIL-STD-2411 [11] CADRG – Compressed ADRG, developed by NGA, nominal compression of 55:1 over ADRG (type of Raster Product Format)

  6. Data model (GIS) - Wikipedia

    en.wikipedia.org/wiki/Data_model_(GIS)

    It was termed "georelational" because in keeping with the principles of relational databases, the geometry and attributes could be joined by matching each shape with a row in the table using a key, such as the row number or an ID number. [20] The spatial database (also called the object-based model [20]) first appeared in the 1990s.

    en.wikipedia.org/wiki/IntelliCAD

    IntelliCAD is a CAD editor and development platform with an API published by the IntelliCAD Technology Consortium (ITC) through shared development. IntelliCAD emulates the basic interface and functions of AutoCAD, however, it is particularly able to incorporate and interchange freely between a wide variety of file types (i.e., .dwg, BIM, TIFF, etc.).

  8. Product key - Wikipedia

    en.wikipedia.org/wiki/Product_key

    The 25 characters of the Product Key form a base-24 encoding of the binary representation of the Product Key. The Product Key is a multi-precision integer of roughly 115 bits, which is stored in little endian byte order in an array of 15 bytes. Of these 15 bytes the least significant four bytes contain the Raw Product Key in little endian byte ...

  9. Spatial reference system - Wikipedia

    en.wikipedia.org/wiki/Spatial_reference_system

    A spatial reference system (SRS) or coordinate reference system (CRS) is a framework used to precisely measure locations on the surface of Earth as coordinates.It is thus the application of the abstract mathematics of coordinate systems and analytic geometry to geographic space.
