  2. GDAL - Wikipedia

    en.wikipedia.org/wiki/GDAL

    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.

  3. GIS file format - Wikipedia

    en.wikipedia.org/wiki/GIS_file_format

    The Object-based model stores them in a single structure, loosely or directly based on the objects in object-oriented programming languages. This is the basis of most modern file formats, including spatial databases that include a geometry column along with the other attributes in a single relational table.

  4. Shapefile - Wikipedia

    en.wikipedia.org/wiki/Shapefile

    It is now possible to read and write geographical datasets using the shapefile format with a wide variety of software. The shapefile format stores the geometry as primitive geometric shapes like points, lines, and polygons. These shapes, together with data attributes that are linked to each shape, create the representation of the geographic data.

  6. GeoJSON - Wikipedia

    en.wikipedia.org/wiki/GeoJSON

    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.

    GeoJSON – open, lightweight format based on JSON, used by many open source GIS packages; GeoMedia – Microsoft Access based format for spatial vector storage (by Intergraph) ISFC – MicroStation based CAD solution attaching vector elements to a relational Microsoft Access database (by Intergraph)

  8. Nim (programming language) - Wikipedia

    en.wikipedia.org/wiki/Nim_(programming_language)

    Nim notably provides type classes which can stand in for multiple types, and provides several such type classes 'out of the box'. Type classes allow working with several types as if they were a single type. For example: openarray – Represents arrays of different sizes, sequences, and strings; SomeSignedInt – Represents all the signed ...

  9. JSON streaming - Wikipedia

    en.wikipedia.org/wiki/JSON_streaming

    JSON streaming comprises communications protocols to delimit JSON objects built upon lower-level stream-oriented protocols (such as TCP), that ensures individual JSON objects are recognized, when the server and clients use the same one (e.g. implicitly coded in). This is necessary as JSON is a non-concatenative protocol (the concatenation of ...
