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 ]
GeoJSON [1] is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.It is based on the JSON format.. The features include points (therefore addresses and locations), line strings (therefore streets, highways and boundaries), polygons (countries, provinces, tracts of land), and multi-part collections of these types.

Certain JSON implementations only accept JSON texts representing an object or an array. For interoperability, applications interchanging JSON should transmit messages that are objects or arrays. The specifications allow JSON objects that contain multiple members with the same name.
The syntax of Nim resembles that of Python. [27] Code blocks and nesting statements are identified through use of whitespace, according to the offside-rule.Many keywords are identical to their Python equivalents, which are mostly English keywords, whereas other programming languages usually use punctuation.
Well-known text (WKT) is a text markup language for representing vector geometry objects. A binary equivalent, known as well-known binary (WKB), is used to transfer and store the same information in a more compact form convenient for computer processing but that is not human-readable.
COFF – (no suffix for executable image, .o for object files) Unix Common Object File Format, now often superseded by ELF; COM – Simple executable format used by CP/M and DOS. DCU – Delphi compiled unit; DLL – Dynamic library used in Windows and OS/2 to store data, resources and code.
