Data conversion tools
- Core geospatial processing libraries:
- ArcPy - Python interface to the ArcGIS geoprocessing framework for automating spatial analysis, data management, and mapping.
- gdal (⭐5.9k) - Translator library for raster and vector geospatial data formats.
- loam (⭐227) - JavaScript wrapper for GDAL in the browser.
- Simplification and generalization:
- Distillery - Web application to simplify and project TopoJSON.
- Feature Service Layer - Use the
maxAllowableOffset parameter to return generalized geometries with the query operation.
- Generalize method - GeometryEngine can produce a geometry with fewer vertices programmatically. Several APIs support it: JavaScript, iOS, Android, .NET, Qt, and Java.
- PostGIS ST_Simplify - This operation returns a simplified version of the given geometry using the Douglas-Peucker algorithm.
- Mapshaper (⭐4.1k) - Web application to simplify shapes, edit attribute data, clip, erase, dissolve, filter, etc. Supported file formats: Shapefile, GeoJSON, TopoJSON, and CSV files.
Data integration tools
- FME Server - ETL allowing to easily transform almost any dataset into an ArcGIS compatible format and vice-versa. Support for 500+ formats and technologies.
- Koop - JavaScript toolkit for connecting spatial APIs. Transform geospatial data on the fly and serve as GeoJSON, vector tiles, feature services, and more.
- node-red-contrib-arcgis-rest - Query, delete, update, or insert data with low-code programming for event-driven applications of the JS Foundation.
- Tray.io - Manual, scheduled, and webhook triggers to apply edits, get features, layers, etc. using Tray Platform's ArcGIS connector.
Debugging tools
- json-schema.org - Vocabulary that allows you to annotate and validate JSON documents (including multiple validators).
- Postman interceptor - Interceptor enables you to sync cookies from your browser and capture network requests directly from Chrome.
- netbalancer.com - Windows application for local network traffic control and monitoring.
Design and styling
- Best practices, books, videos, and training:
Developer guides
- Data hosting - Store, manage, and access your data as data services.
- Demographics - Discover local facts and demographic information with the GeoEnrichment service.
- Maps - Display 2D maps and 3D scenes using the basemap layer service and data services.
- Offline - Display, analyze, and edit data while disconnected.
- Routing - Find routes and directions with the routing service.
Helpers
- esri-loader (⭐460) - A tiny library to help you lazy-load the ArcGIS API for JavaScript (i.e., from the CDN) in applications built with popular JavaScript frameworks and bundlers.
- react-sceneview (⭐12) - A simple Esri SceneView React component that builds on the ArcGIS API for JavaScript.
Map and data exploration
- ArcGIS Map Viewer - Web application to create, explore, and share web maps for 2D applications.
- ArcGIS Scene Viewer - Web application to create, explore, and share web maps for 3D applications.
- geojson.io (⭐2.1k) - Web application to visualize, generate, and edit geospatial vector data. Supports GeoJSON, TopoJSON, CSV, KML, WKT, and Shapefile.
- Mapshaper (⭐4.1k) - Web application to simplify shapes, edit attribute data, clip, erase, dissolve, filter, etc. Supported file formats: Shapefile, GeoJSON, TopoJSON, and CSV files.
- Smart Mapping - It is built into the Map and Scene viewer, but some APIs like JavaScript and Python also provide utilities to help build data exploration tools.
Playgrounds
- arcgis-arcade-playground - Try the portable scripting language for creating ArcGIS custom visualizations and labeling expressions.
- geometry-inspector - Quickly show EsriJSON, GeoJSON, or WKT on a map, or draw on a map to get EsriJSON, GeoJSON, or WKT.
Spatial Analysis
Specifications
- Common data types - JSON formats of the geometry and spatial reference objects as returned by ArcGIS REST API: Point, Multipoint, Polyline, Polygon and Envelope.
- GeoServices spec (⭐103) - Open Web Foundation REST-based API that provides complete access to structured geospatial data used by Esri.
- Spatial reference specifications - List of Well-Known ID (WKID) integer value or a text string definition referred to as Well-Known Text (WKT) to define a spatial reference.
- Web Map spec - Sharable 2D maps. It describes the JSON object that defines a web map.
- Web Scene spec - A JSON structure that defines the contents (viewpoint, camera, basemap layer, layers, styles, etc.) for a shareable 3D scene.
