1. Gratic

Gratic operates as a vector cartography editor for orienteering and terrain maps that runs directly inside an open browser tab.

Overview

The software runs on any modern browser across Windows, Linux, and macOS without local installers or client binaries. Organizers drag a bounding box over their competition terrain to stream height values and public vector data straight into an active document. Surveyors access projects using an email sign-in code without needing to manage passwords or balance client seats.

Key Features

Gratic structures elevation data tile by tile from connected spatial repositories, enabling mappers to inspect terrain contours without indexing raw tiles manually. The editor generates contours and terrain breaklines directly at user-selected vertical intervals inside the document. Connected data services include land surveys in Finland, PDOK in the Netherlands, IGN in France, and the national cadastre in Cyprus, alongside worldwide OpenStreetMap queries. Built-in tools allow teams to import scanned historical surveys and georeference them against satellite imagery in the same view. Files export directly in formats compatible with OCAD.

Pros

Cons

Best for

Gratic is purpose-built for sports cartography, terrain navigation, and orienteering course production.

2. Felt

Felt provides an AI-native GIS platform designed for distributed teams conducting spatial analysis and collaborative map drafting inside a web browser.

Overview

Felt delivers spatial data handling through browser-based interfaces, combining SQL workflows, design styling, and real-time collaboration. The tool ingests structured files and live cloud sources without requiring desktop software configuration. Teams can generate interactive dashboards, compute raster layers, and review shared trail routes simultaneously.

Key Features

Felt connects directly to databases, warehouses, and storage buckets to load geodata without manual local conversion. The platform accepts almost any spatial file format, including Shapefiles, GeoJSON, GeoPackages, KML, File Geodatabases, and GeoTIFFs, with a file size limit of up to 100 GB each. Its Felt AI interface allows mappers to ask questions and build maps in plain language. Field teams can log on-site track information offline using the dedicated field application. Processing complies with SOC 2 Type 2 and GDPR standards, maintaining private maps until users share them.

Pros

Cons

Fees

The free plan includes 3 seats and 25 viewers. Viewers are free on every plan, and nothing is added automatically to invoices.

3. ArcGIS Online

ArcGIS Online delivers cloud-hosted GIS mapping that connects data through geography and browser-based spatial analytics.

Overview

Operated by Esri, ArcGIS Online allows institutions to create, analyze, and store spatial datasets within managed cloud infrastructure. The platform links field workers, analytical models, and public-facing map interfaces. Its services support hosted DEM layer elevation analysis and multi-region cloud data storage hosting.

Key Features

ArcGIS Online hosts, publishes, and manages data as hosted web layers. Mappers can deploy hosted elevation layers to model terrain values, derive elevation profiles, and visualize elevation models. The software connects with enterprise infrastructure including Snowflake, BigQuery, Databricks, Microsoft Azure, Autodesk, and AWS. Mobile tracking and data collection operate through ArcGIS Field Maps, while real-time data analysis runs through the ArcGIS Velocity add-on. Systems operate under FedRAMP Moderate and ISO 27001 compliance.

Pros

  • On direct vector and geodata imports, Felt and Mapshaper spell this out in more detail.
  • On real-time team collaboration and sharing, Gratic spells this out in more detail.
  • On local browser-only processing and privacy, EasyMaps and Felt spell this out in more detail.

4. OCAD

OCAD produces vector-based cartography software developed in Switzerland for creating and publishing specialized maps.

Overview

OCAD has developed professional software for map production since 1989. The desktop software provides precise drawing environments configured for sport navigation, topographical publishing, and city layout plans. Surveyors pair the desktop environment with handheld devices to gather point data and mark terrain obstacles.

Key Features

The software features digital elevation model support with contour generation and hill shading, alongside GPX and KML import. Users analyze vegetation and terrain structure through processed LiDAR and DEM data. The OCAD App connects digital field mapping on mobile devices directly with desktop map projects. Drawing suites include legibility verification tools, route analyzers, and direct upload pipelines to sports platforms like Livelox and SPORTident Center.

Pros

  • Native tools evaluate terrain profiles and vegetation density directly from LiDAR sources.
  • Integrates mobile track recording with desktop projects via the OCAD App.
  • Exports directly to competitive timing and tracking systems like SPORTident Center and Livelox.

Cons

  • On direct vector and geodata imports, Felt and Mapshaper spell this out in more detail.
  • On real-time team collaboration and sharing, Gratic spells this out in more detail.
  • On 3D terrain rendering and elevation profiles, ArcGIS Online and Felt spell this out in more detail.

5. Mapshaper

Mapshaper is a free and open-source spatial data editing tool that operates inside modern web browsers.

Overview

Mapshaper processes vector geography in client-side memory using visual controls or terminal-style commands. The platform executes topological simplification, attribute modification, and format conversions without server uploads. Cartographers use it to inspect surveyed boundaries, clip track extents, and sanitize geodata files.

Key Features

The editor imports Shapefile, GeoJSON, TopoJSON, GeoPackage, FlatGeobuf, GeoParquet, GeoTIFF, KML, and CSV files. Mappers can run sequentially chained commands from left to right through a command-line interface. Core features support shape simplification, polygon clipping, erasing, dissolving, and attribute filtering. The web application runs in recent versions of Chrome, Firefox, Safari, and Internet Explorer.

Pros

  • All spatial calculations run in browser memory so data stays on the local machine.
  • Supports complex format transformation and shape simplification across major vector standards.
  • Includes an integrated command-line interface for batch spatial manipulation.

How we compared

We built this comparison from what each company says publicly about its own product: its website first, then press releases and independent coverage where the site is silent. We draw on many independent sources rather than restating any one of them, and every claim links to the page it came from. Where a firm clearly does not offer something, the table shows ✗. Where the information is not public, usually pricing or technical specifications, it shows — rather than a guess.

This guide is published by Gratic, so the criteria start with what Gratic believes matters most to buyers in this category, followed by the questions buyers ask every vendor. Gratic's own limitations sit alongside everyone else's.
