MapShaper - Tools for editing Shapefile, GeoJSON, TopoJSON and CSV files

  •        54

Mapshaper is software for editing Shapefile, GeoJSON, TopoJSON, CSV and several other data formats, written in JavaScript. The mapshaper command line program supports essential map making tasks like simplifying shapes, editing attribute data, clipping, erasing, dissolving, filtering and more.

shapefile - A cross-platform streaming parser for the ESRI Shapefile spatial data format.

For a live example, see See also ndjson-cli for examples of manipulating GeoJSON using newline-delimited JSON streams. See Command-Line Cartography for a longer introduction. In-browser parsing of dBASE table files requires TextDecoder, part of the Encoding living standard, which is not supported in IE or Safari as of September, 2016. See text-encoding for a browser polyfill.

leaflet-omnivore - universal format parser for Leaflet & Mapbox.js

Leaflet supports the GeoJSON format by default. What if you have something else? That's where omnivore comes in.Omnivore also includes an AJAX library, corslite, so you can specify what you want to add to the map with just a URL.

PostGIS - Spatial and Geographic objects for PostgreSQL

PostGIS is a spatial database extender for PostgreSQL object-relational database. It adds support for geographic objects allowing location queries to be run in SQL. PostGIS adds extra types (geometry, geography, raster and others) to the PostgreSQL database. It also adds functions, operators, and index enhancements that apply to these spatial types.

geobuf - A compact binary encoding for geographic data.

Geobuf is a compact binary encoding for geographic data.Think of this as an attempt to design a simple, modern Shapefile successor that works seamlessly with GeoJSON. Unlike Mapbox Vector Tiles, it aims for lossless compression of datasets — without tiling, projecting coordinates, flattening geometries or stripping properties.

tippecanoe - Build vector tilesets from large collections of GeoJSON features.

Builds vector tilesets from large (or small) collections of GeoJSON, Geobuf, or CSV features, like these.The goal of Tippecanoe is to enable making a scale-independent view of your data, so that at any level from the entire world to a single building, you can see the density and texture of the data rather than a simplification from dropping supposedly unimportant features or clustering or aggregating them.

topogram - Continuous area cartograms with d3 and TopoJSON

This is a JavaScript implementation of an algoritm to construct continuous area cartograms, by James A. Dougenik, Nicholas R. Chrisman and Duane R. Niemeyer, ©1985 by the Association of American Geographers. It relies heavily on d3 for rendering and TopoJSON both for writing and reading topological JSON geodata. The included example combines TopoJSON-encoded and boundaries of the United States from Natural Earth with 2011 US Census population estimates to size each state proportionally.

turf - A modular geospatial engine written in JavaScript

Turf is a JavaScript library for spatial analysis. It includes traditional spatial operations, helper functions for creating GeoJSON data, and data classification and statistics tools. Turf can be added to your website as a client-side plugin, or you can run Turf server-side with Node.js (see below).Download the minified file, and include it in a script tag. This will expose a global variable named turf.

tiled - A generic tile map editor

Tiled is a general purpose tile map editor. It is meant to be used for editing maps of any tile-based game, be it an RPG, a platformer or a Breakout clone. Tiled is very flexible, for example there are no restrictions on map size, tile size or the number of layers or tiles. Also, it allows arbitrary properties to be set on the map, its layers, the tiles or on the objects. Its map format (TMX) is relatively easy to understand and allows a map to use multiple tilesets while also allowing each tileset to grow or shrink as necessary later.

Inkscape - Vector Graphics Editor

Inkscape is a vector graphics editor, with capabilities similar to Illustrator, CorelDraw, or Xara X, using the W3C standard Scalable Vector Graphics (SVG) file format. It supports many advanced SVG features (markers, clones, alpha blending, etc.) and great care is taken in designing a streamlined interface. It is very easy to edit nodes, perform complex path operations, trace bitmaps and much more.
