OpenStreetMap ( OSM) is a free, open geographic database updated and maintained by a community of volunteers via open collaboration. Contributors collect data from surveys, trace from aerial imagery and also import from other freely licensed geodata sources. OpenStreetMap is freely licensed under the Open Database License and as a result ...
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. As a library, it presents a single abstract data model to the ...
Mapnik is an open-source mapping toolkit for desktop and server based map rendering, written in C++. Artem Pavlenko, the original developer of Mapnik, set out with the explicit goal of creating beautiful maps [2] by employing the sub-pixel anti-aliasing of the Anti-Grain Geometry (AGG) library. Mapnik now also has a Cairo rendering backend.
QGIS is a geographic information system (GIS) software that is free and open-source. [ 2] QGIS supports Windows, macOS, and Linux. [ 3] It supports viewing, editing, printing, and analysis of geospatial data in a range of data formats. QGIS was previously also known as Quantum GIS.
josm .openstreetmap .de. JOSM ( listen ⓘ) (Java OpenStreetMap editor) is a free software desktop editing tool for OpenStreetMap geodata created in Java, originally developed by Immanuel Scholz and currently maintained by Dirk Stöcker. [ 5] The editing tool contains advanced features [ 6] that are not present in OSM's default online editor, iD .
Align the map to the area you want to edit. Click 'Edit' by the website banner. Now you should see the 'Add Feature' options at the top, with buttons for 'Point', 'Line', and 'Area'. Click 'Area'. You can now start to form a shape, clicking on each corner, adjusting the edges of the shape as needed.
OpenStreetMap Foundation. / 52.55098; -1.81860. The OpenStreetMap Foundation (abbreviated OSMF) is a non-profit foundation whose aim is to support and enable the development of freely-reusable geospatial data. Founded in 2006, it is closely connected with the OpenStreetMap project, although its constitution does not prevent it supporting other ...
Graphics software (Inkscape) ≠ mapping software (QGIS can "read" the georeferencing of a file); With matrix as well as vector sources, you can create files via QGIS matrix as well as vector; Vector graphics consist of points, lines and polygons (and possibly polylines or relations). Anglicisms: Matrix = * = bitmap raster vector ≠.
