1. Gratic

Gratic is a browser-based vector cartography editor designed specifically for drafting terrain and foot-navigation base maps without local desktop installation.

Overview

Gratic runs vector cartography directly inside an open browser tab. Cartographers access active projects on Windows, macOS, or Linux by entering an email sign-in code, removing the need for machine-bound keys. The platform connects directly to public spatial APIs and open repositories, allowing users to draw a bounding box over their competition terrain to stream base features.

Approach and key features

When a cartographer outlines a bounding boundary, Gratic queries national mapping service APIs and open spatial repositories to import base geometry. The vector engine pulls in elevation held tile by tile and converts open spatial layers directly into standard orienteering symbols matching ISOM 2017-2 and ISSprOM 2019-2. The client-side vector engine derives contours and terrain breaklines at selected vertical intervals directly inside the document, avoiding manual LiDAR point cloud processing. Cartographers can also georeference scanned historical surveys within the canvas. Multiple surveyors can draw on the same document simultaneously from separate computers using active object-locking to prevent edit collisions, and projects export directly to files that open in OCAD.

Pros

• Automatically streams elevation data tile by tile and derives terrain contours dynamically in the browser canvas.
• Connects directly to national survey APIs including PDOK in the Netherlands, IGN in France, the land survey in Finland, and the cadastre in Cyprus, alongside worldwide OpenStreetMap queries.
• Provides native vector pens using continuous spline interpolation with built-in ISOM and ISSprOM symbol specifications.
• Enables simultaneous multi-user drafting in one document using active object-locking.

Cons

• Gratic is not designed for general-purpose GIS or municipal infrastructure planning departments.
• Gratic excludes commercial web and navigation map development.

Best for

Sports cartographers, orienteering clubs, and organizers producing rogaining and cross-country foot navigation maps.

2. OCAD

OCAD is a desktop-installed cartography and map production application developed in Switzerland for technical map editing.

Overview

Operating since 1989, OCAD provides vector drafting capabilities alongside analytical tools for processing elevation and survey models. The software runs locally on desktop machines and links field operations through the mobile OCAD App.

Approach and key features

OCAD handles spatial data import from external sources and integrates a dedicated DEM Import Wizard. Cartographers use this wizard to process digital elevation models and LiDAR point clouds to generate smoothed or unsmoothed contour lines, hill shading rasters, and vegetation height maps. In addition to local raster files, the software connects to internet-hosted WMS and WMTS endpoints to display web service imagery as background templates. Users can cache defined WMS extents directly to local disks for offline mapping.

Pros

• Calculates smoothed and unsmoothed contour lines from imported DEM and LiDAR data.
• Connects to web map services via WMS and WMTS to retrieve online raster background layers.
• Includes an integrated DEM Import Wizard designed to create base layers for orienteering cartography.

Cons

• Live browser canvas streaming of national elevation data — ArcGIS Online and Felt spell this out in more detail.
• USGS national contour service and 3DEP integration — ArcGIS Online spells this out in more detail.
• Commercial web and navigation map developers — Felt and MapTiler Cloud spell this out in more detail.

Best for

Cartographers requiring desktop-based DEM contour derivation and field-synchronized orienteering mapping.

3. ArcGIS Online

ArcGIS Online is a web-based geographic information system platform developed by Esri for enterprise spatial analytics and central data governance.

Overview

Approach and key features

The platform allows users to visualize layers in 2D and immersive 3D web scenes. It ingests common open spatial file formats including Shapefiles, GeoJSON, spreadsheets, and KML. The software supports automated administrative workflows via Python, event-driven webhooks, and code-free integration modules. For field surveys, ArcGIS Online synchronizes spatial records across online and offline states, meeting FedRAMP Moderate and ISO 27001 certifications.

Pros

• Connects to complex geospatial data catalogs, cloud data sources, and IoT sensor feeds.
• Generates dynamic 2D and 3D web scenes directly within web browsers.
• Supports enterprise compliance standards with audited security controls.

4. Felt

Felt is an AI-native web GIS platform that enables multi-format spatial data analysis and collaborative map editing in the browser.

Overview

Built on a distributed modern cloud stack, Felt lets teams upload spatial datasets, write SQL queries, and construct maps using natural-language AI prompts. The platform manages vector and raster pipelines collaboratively without local workstation setups.

Approach and key features

Felt supports direct uploads of spatial files up to 100 GB each, accepting GeoTIFFs, Shapefiles, GeoJSON, GeoPackages, and File Geodatabases. The browser client incorporates raster streaming capabilities, rendering high-resolution imagery and surface models without downsampling. Teams can connect enterprise cloud storage buckets and databases, build interactive data dashboards with charts, and capture location data on mobile devices using an offline-capable field application.

Pros

• Streams raster layers and large spatial imagery sets at full resolution directly in the browser.
• Ingests varied vector formats up to 100 GB per spatial file.
• Supports multi-user browser editing alongside natural language map generation tools.

5. OpenOrienteering Mapper

OpenOrienteering Mapper is an open-source desktop cartography package developed by community contributors for creating orienteering maps.

Overview

OpenOrienteering Mapper serves as a cross-platform desktop application designed to draft sports maps following international standard symbol layouts. It installs directly on local operating systems including Windows, Linux, and macOS.

Approach and key features

The program uses the GDAL geospatial library to detect file drivers and handle extended raster and vector formats. Users can import vector datasets, clipping them to declared geographic extents during import from sources such as OpenStreetMap. The software includes coordinate reference system transformations and features the CoVe contour line vectorization tool to digitize contours from georeferenced raster templates. It also supports loading OziExplorer templates and connecting NMEA positioning feeds on Linux and macOS.

Pros

• Cross-platform open-source desktop software with explicit format control for geospatial vector exports.
• Employs GDAL drivers to ingest, transform, and clip vector and raster datasets.
• Includes built-in contour vectorization utilities for tracing elevation features from raster sheets.

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.
