Atlas vs Global Mapper

Atlas and Global Mapper represent two different philosophies in GIS: browser-based collaboration versus desktop processing power. If your team is debating whether to invest in a cloud mapping platform or a desktop GIS workhorse, this comparison covers the key differences to help you decide.

Introducing Atlas and Global Mapper

Atlas

Atlas is a browser-based collaborative GIS platform for teams. It combines a no-code map builder, real-time collaboration, spatial analysis, and an app builder with forms, filters, and dashboards. Everything runs in the browser — no installs, no license servers, no IT tickets.

Global Mapper

Global Mapper is a desktop GIS application developed by Blue Marble Geographics. It is known for supporting an exceptionally wide range of data formats (300+), affordable pricing relative to other desktop GIS tools, and strong LiDAR processing capabilities. It runs on Windows and includes both vector and raster analysis tools.

Quick Comparison Table

Platform and Accessibility

Atlas

Atlas runs in any modern browser on any operating system. There is nothing to install, update, or manage. Your entire team accesses the same projects from anywhere, and stakeholders view shared maps without creating accounts.

• Pros: Zero IT overhead, cross-platform, accessible from any device
• Cons: Requires internet connection, no offline processing for large local files

Global Mapper

Global Mapper is a Windows-only desktop application. Each user needs a license installed on their machine. It processes data locally, which can be an advantage for large files and sensitive data that cannot leave the organization.

• Pros: Local processing for large datasets, works offline, no dependency on internet
• Cons: Windows-only, requires installation and license management, no mobile access

Which to Choose?

Choose Atlas if your team works across devices and locations and you want zero-install onboarding. Choose Global Mapper if you need to process large files locally on a Windows workstation, especially in environments with limited internet access.

Ease of Use

Atlas

Atlas is built so that someone without GIS training can upload data, build a map, and share it within minutes. The interface uses drag-and-drop, inline help, and visual configuration — no menus buried three levels deep.

• Pros: Fastest path from data to shareable map, accessible to non-GIS users
• Cons: Less control over advanced cartographic output and coordinate system management

Global Mapper

Global Mapper is considered one of the more approachable desktop GIS tools, but it still assumes familiarity with GIS concepts like coordinate systems, projections, and attribute tables. The interface is functional but dense, with toolbar-heavy navigation.

• Pros: More accessible than ArcGIS or QGIS for desktop GIS, good documentation and tutorials
• Cons: Still requires GIS knowledge, interface can feel dated, learning curve for LiDAR workflows

Which to Choose?

Atlas wins on onboarding speed for mixed teams. Global Mapper is the better pick when your users already have GIS fundamentals and need a capable desktop environment that is less intimidating than ArcGIS.

Collaboration and Sharing

Atlas

Collaboration is a central feature. Multiple users work on the same map simultaneously, leave comments on features, manage permissions, and share live interactive maps via link. Embedding maps in websites takes a single copy-paste.

• Pros: Real-time co-editing, comments, role-based permissions, no-login sharing, embeds
• Cons: All collaboration requires internet access

Global Mapper

Global Mapper has no built-in collaboration. Sharing means exporting a file (Shapefile, KMZ, PDF map) and sending it to a colleague. There is no web publishing, no live sharing, and no multi-user editing.

• Pros: Files can be shared through any method (email, cloud storage, USB)
• Cons: No real-time collaboration, no interactive web maps, file-based sharing is slow and lossy

Which to Choose?

If your workflow involves multiple people reviewing, editing, or interacting with maps, Atlas is the clear choice. If your workflow is single-user desktop processing with occasional file handoffs, Global Mapper's export options may suffice.

Data Formats and LiDAR

Atlas

Atlas supports the most common web GIS formats: CSV, GeoJSON, Shapefile (zipped), KML, and GPX. The built-in geocoder handles address-to-coordinate conversion. It focuses on vector data for mapping and operational workflows.

• Pros: Covers the most common import needs, built-in geocoding, seamless upload
• Cons: No raster import, no LiDAR support, no CAD format reading

Global Mapper

Global Mapper is a format powerhouse. It reads and writes over 300 spatial data formats including Shapefiles, GeoTIFF, ECW, MrSID, LAS/LAZ (LiDAR), DWG/DXF (CAD), FGDB, and many more. Its LiDAR module supports point cloud classification, filtering, feature extraction, and terrain model generation.

• Pros: Industry-leading format support, full LiDAR processing suite, raster and vector in one tool
• Cons: Format breadth adds interface complexity, LiDAR module costs extra

Which to Choose?

If you work with LiDAR data, raster imagery, or obscure formats, Global Mapper is likely the only tool you need. If your data is vector-based (spreadsheets, GeoJSON, Shapefiles) and your goal is to map and share it, Atlas handles those formats with far less friction.

Spatial Analysis

Atlas

Atlas provides no-code spatial analysis: buffers, spatial joins, heatmaps, geocoding, and attribute-based filtering. Results appear as new layers on the interactive map, ready to share immediately.

• Pros: Analysis accessible to non-technical users, results are instantly shareable
• Cons: No terrain analysis, viewshed, watershed, or raster-based operations

Global Mapper

Global Mapper offers a broad range of analysis tools: terrain analysis, watershed delineation, viewshed calculation, raster math, volume calculation, contour generation, and vector geoprocessing. It handles both raster and vector analysis in a single application.

• Pros: Deep analysis toolset covering terrain, hydrology, and volumetrics, combines raster and vector
• Cons: Analysis results stay on the desktop; sharing requires export and separate distribution

Which to Choose?

Atlas is the right pick for operational vector analysis that needs to be shared with a team. Global Mapper is the right pick for terrain-focused, raster-heavy, or LiDAR-based analysis where processing power and format flexibility matter more than sharing.

Cost and Pricing

Atlas

Atlas has a free tier for individuals and small teams. Paid plans scale with projects, storage, and team seats. Pricing is transparent and published on the website, with no hidden costs.

• Pros: Free tier, predictable scaling, no per-machine licensing headaches
• Cons: Enterprise features (SSO, dedicated support) cost more

Global Mapper

Global Mapper costs approximately $535 per year for a standard license. The LiDAR module adds roughly $300 per year. Each user needs their own license. Volume discounts are available for larger organizations.

• Pros: Very affordable for desktop GIS, perpetual license options available, clear per-seat pricing
• Cons: Per-machine licensing adds up for teams, LiDAR is an extra cost, no free tier

Which to Choose?

Atlas is more cost-effective for teams that need collaboration and sharing — one platform replaces the need for per-user desktop licenses plus a separate sharing solution. Global Mapper is an excellent value for individual GIS analysts who need a desktop processing powerhouse.

Final Thoughts

Atlas and Global Mapper serve different stages of the GIS workflow. Global Mapper excels at processing; Atlas excels at collaboration and delivery.

Choose Atlas if you:

• Need a team-wide platform for mapping, analysis, and sharing — all in the browser
• Want non-technical stakeholders to access and interact with maps
• Value real-time collaboration and instant web publishing
• Work primarily with vector data and operational workflows

Choose Global Mapper if you:

• Need to process LiDAR, raster, or CAD data on the desktop
• Require support for 300+ spatial data formats
• Need terrain analysis, viewshed, or watershed tools
• Work as an individual analyst or small GIS team on a Windows workstation
