Placematic Mapping & GIS Tools

Free online tools for working with maps, GeoJSON and HERE APIs. No login required.

GeoJSON Editor

Tool to verify and visualize your data stored as a GeoJSON. Just paste it in textarea to confirm that's correct, as well as an visualize it on the map.

HERE Polyline Decoder

Tool to validate, convert, visualize and interact with polyline data directly on an interactive map.

HERE Polyline Encoder

Tool to validate, visualize, and instantly convert GeoJSON data into polyline format on an interactive map.

HERE Route v8 Decoder

Tool to validate, decode, visualize, and convert HERE Routing API v8 responses, including polyline geometry and all route sections, directly on an interactive map.

Our free geospatial converter tools help developers work faster with location data. Whether you need to validate a GeoJSON file, decode a HERE Flexible Polyline, or inspect a HERE Route v8 API response — these tools let you do it instantly in the browser, without writing a single line of code.

HERE API Developer Playground

A collection of interactive tools for exploring, testing, and understanding HERE APIs.

HERE Truck Routing API

It’s designed as a developer-friendly demo / helper tool for working with HERE routing (for logistics/truck or other transport modes) inside the Placematic environment.

HERE EV Routing API

This tool is a web-based EV route planner built with HERE Routing v8 API. It automatically adds optimal charging stops, visualizes the full trip on a map, and exposes all EV routing parameters, requests, and responses for developers.

HERE Route Optimization API

This tool is designed as a developer-friendly helper for testing, understanding, and integrating HERE Route Optimization / Waypoint Sequence capabilities.

HERE Isochrone API

It’s intended as a developer tool/demo for exploring HERE isochrones within the Placematic environment.

HERE Autocomplete and Lookup API

This tool is designed as a developer-friendly helper for testing, understanding, and integrating the HERE Search stack.

HERE Reverse Geocoding API

This tool is designed as a developer-friendly helper for testing, understanding, and integrating the HERE Reverse Geocoding stack.

HERE POI Discover API

This tool is designed as a developer-friendly helper for testing, exploring, and integrating the HERE POI Discover API.

HERE Map Tile API

Tool offers a clean and efficient way to interact with HERE’s map styles, traffic overlays, and tile infrastructure.

The HERE API Developer Playground is a set of interactive demos built on top of HERE Technologies APIs. Each tool lets you test real API requests — routing, geocoding, isochrones, EV charging stops, POI discovery — directly in the browser with live map visualization. Designed for developers evaluating HERE APIs and building location-aware applications.
