Stop Hunting for ATAK Maps! This Repo Has 30+ Sources Ready

What if your next mission failed because you couldn't access the right map?

Picture this: You're deployed in a remote area with zero connectivity. Your team depends on accurate geospatial data for navigation, situational awareness, and mission planning. You open Android Tactical Assault Kit (ATAK)—the gold standard for tactical mapping—and realize your map layers are outdated, incomplete, or simply missing. Panic sets in. Every minute spent scrambling for map sources is a minute lost to operational readiness.

Sound familiar? You're not alone. Thousands of military personnel, first responders, and outdoor professionals face this exact bottleneck. Manually configuring map sources in ATAK is tedious, error-prone, and requires deep knowledge of XML formatting and the MOBAC specification. One syntax error, and your map layer fails silently. Worse, finding reliable, current map URLs scattered across the internet feels like a full-time job.

Here's the secret most operators don't know: There's a meticulously maintained repository that eliminates this friction entirely. ATAK-Maps by Joshua Fuller is a battle-tested collection of 30+ pre-configured XML map files, ready to drop into ATAK and deploy. No XML wrangling. No broken URLs. No guesswork. Just instant access to Google Satellite, USGS topo maps, ESRI clarity layers, OpenSeaMap nautical charts, and dozens more.

In this guide, I'll expose exactly how this repository works, why it's becoming the standard for ATAK users worldwide, and how you can install it in under three minutes. Whether you're coordinating disaster relief, conducting search-and-rescue, or planning tactical operations, this is the map source solution you've been missing.

What is ATAK-Maps?

ATAK-Maps is a comprehensive, open-source collection of XML configuration files formatted in the Mobile Atlas Creator (MOBAC) specification. Created and maintained by Joshua Fuller, this repository serves as a centralized hub for ATAK-compatible map sources that would otherwise require hours of manual research and configuration.

The repository has gained significant traction across defense, public safety, and outdoor recreation communities. With automated XML validation via GitHub Actions, semantic versioning releases, and an active Discord community of over 500 members, ATAK-Maps represents a mature, production-ready resource that continues to evolve.

Why It's Trending Now

Three forces are driving ATAK-Maps' explosive growth:

1. ATAK adoption is accelerating: Originally developed for military use, ATAK has expanded into law enforcement, fire services, emergency management, and even civilian applications like wilderness search and rescue. More users means more demand for plug-and-play map solutions.

2. The MOBAC barrier: The Mobile Atlas Creator format, while powerful, has a steep learning curve. ATAK-Maps abstracts this complexity entirely, democratizing access to professional-grade map layers.

3. Offline-first operations: Modern tactical scenarios increasingly require functionality without connectivity. ATAK-Maps' structured XML files enable reliable offline caching—a non-negotiable for field operations.

Critical distinction: This repository and its contents are not affiliated with TAK.GOV. It's an independent, community-driven project that complements official ATAK distributions.

Key Features That Make ATAK-Maps Essential

Pre-Configured XML Map Sources

Each XML file in ATAK-Maps acts as a pointer to online map services, defining URL patterns, zoom levels, tile formats, and coordinate systems. The repository handles the intricate MOBAC syntax so you don't have to. Every file is validated automatically via GitHub Actions, ensuring XML integrity before release.

Dynamic Map Access

ATAK-Maps facilitates real-time map streaming from diverse providers. Need Google Satellite imagery for urban operations? USGS topo maps for wilderness navigation? ESRI clarity layers for infrastructure assessment? Switch between sources dynamically based on your operational context.

Robust Offline Caching

ATAK's native caching capability pairs perfectly with ATAK-Maps' structured sources. Pre-download mission-critical areas at your desired zoom levels and image quality. This isn't just convenient—it's mission-critical for environments with jammed, degraded, or non-existent communications.

Extensive Provider Coverage

The repository spans multiple provider categories:

Automated Release Pipeline

The project uses semantic-release with Conventional Commits. Push a feat: or fix: commit to master, and the Map Release workflow automatically tags, versions, and publishes atak-maps.zip. This means updates arrive fast and predictably.

Community-Driven Expansion

New map sources are added based on user demand. Have a specific requirement? Open an issue. The contribution guidelines and custom map creation docs lower the barrier for community additions.

Real-World Use Cases Where ATAK-Maps Dominates

1. Military Tactical Operations

Platoons operating in denied or contested environments need multiple map sources for redundancy. ATAK-Maps provides instant access to satellite imagery for objective analysis, topographic maps for route planning, and hybrid layers for combined situational awareness. Offline caching ensures functionality when satellite uplinks are compromised.

2. Search and Rescue (SAR) Missions

SAR teams operate under extreme time pressure across diverse terrains. Switching between OpenTopo for mountainous regions, USGS imagery for rural areas, and Google Hybrid for urban search patterns—all without manual configuration—saves critical minutes. The ability to cache search grids beforehand eliminates connectivity dependencies in remote locations.

3. Disaster Response and Emergency Management

Hurricane response teams leverage FEMA flood hazard overlays from ATAK-Maps to identify at-risk zones. ESRI clarity layers reveal infrastructure damage. NAIP agricultural imagery assists in assessing rural impact. Multiple map sources enable comprehensive damage assessment without sourcing configurations during crisis conditions.

4. Law Enforcement and Border Security

Officers conducting surveillance or tactical operations require current, high-resolution imagery. Google Satellite and Bing layers provide visual detail, while topographic sources support terrain-aware positioning. The ability to quickly switch sources based on operational phase (planning vs. execution) enhances tactical flexibility.

5. Maritime and Coastal Operations

OpenSeaMap integration delivers nautical chart data including seamarks and base charts for waterborne operations. This specialized data, typically requiring separate navigation systems, integrates directly into ATAK's unified interface.

6. Outdoor Recreation and Wilderness Guiding

Professional guides and recreational users benefit from MTBMap.cz for European cycling routes, CycleOSM for global trail networks, and detailed topographic coverage. The offline caching capability is essential for multi-day expeditions beyond cellular range.

Step-by-Step Installation & Setup Guide

Getting ATAK-Maps operational takes less than three minutes. Follow these exact steps:

Method 1: Standard Installation (Recommended)

Step 1: Download the Release Package

Navigate to the Releases page and download the latest atak-maps-<version>.zip file. The semantic versioning ensures you know exactly what you're getting—major.minor.patch format indicates feature additions, improvements, and fixes respectively.

# Alternative: Direct download via command line (replace VERSION with actual release)
curl -L -o atak-maps.zip https://github.com/joshuafuller/ATAK-Maps/releases/download/v2.1.0/atak-maps-2.1.0.zip

Step 2: Import into ATAK

1. Open ATAK on your Android device
2. Access the Import Manager (typically via the menu or hamburger icon)
3. Select the downloaded ZIP file
4. ATAK automatically extracts and processes all XML map configurations

Step 3: Verify Installation

1. Open ATAK's map layer selector
2. Scroll through available layers—you should see all catalog entries (Google Satellite, USGS Topo, Bing Hybrid, etc.)
3. Select a layer to confirm imagery loads correctly

Method 2: Manual Installation

For advanced users or troubleshooting scenarios:

# Clone the repository for manual file management
git clone https://github.com/joshuafuller/ATAK-Maps.git

# Navigate to XML source files
cd ATAK-Maps/maps

# Individual XML files can be copied to ATAK's map directory
# Location varies by ATAK version and device configuration

Environment Setup for Contributors

If you're extending or validating map sources:

# Fork and clone the repository
git clone https://github.com/YOUR_USERNAME/ATAK-Maps.git
cd ATAK-Maps

# Install XML validation dependencies (if modifying validation workflow)
# The repository uses GitHub Actions for automated validation
# Local validation can be performed with standard XML tools

# Validate a specific map file
xmllint --noout --schema mobac.xsd maps/google_satellite.xml

Offline Caching Configuration

To maximize mission readiness:

1. Identify your operational area in ATAK
2. Select desired map layers from ATAK-Maps catalog
3. Set zoom range: Balance detail vs. storage (typically levels 12-16 for tactical use)
4. Initiate download: ATAK caches tiles automatically as you browse, or use explicit download regions
5. Verify cache completeness: Test in airplane mode before deployment

Pro tip: Cache multiple map types for the same area. If one source fails or shows outdated imagery, switch instantly to your backup layer.

REAL Code Examples from the Repository

Understanding ATAK-Maps' internals empowers advanced customization and troubleshooting. Here are actual patterns from the repository, explained in detail.

Example 1: Basic MOBAC XML Structure (Google Satellite)

This is the foundational pattern used across ATAK-Maps. Every XML file follows this structure to define map source connectivity:

<?xml version="1.0" encoding="UTF-8"?>
<!-- Standard XML declaration with UTF-8 encoding for international character support -->
<customMapSource>
  <!-- Root element identifying this as a custom map source for MOBAC/ATAK -->
  <name>Google - Satellite Only</name>
  <!-- Human-readable name appearing in ATAK's layer selector -->
  <minZoom>0</minZoom>
  <!-- Minimum zoom level: 0 shows entire world as single tile -->
  <maxZoom>20</maxZoom>
  <!-- Maximum zoom level: 20 provides ~15cm/pixel resolution in urban areas -->
  <tileType>jpg</tileType>
  <!-- Image format: jpg for photographic imagery (smaller files), png for transparency -->
  <url>https://mt{$serverpart}.google.com/vt/lyrs=s&amp;x={$x}&amp;y={$y}&amp;z={$z}</url>
  <!-- URL template with variables:
       {$serverpart} = load-balanced server selection (typically 0-3)
       {$x} = tile column index
       {$y} = tile row index  
       {$z} = zoom level
       lyrs=s parameter requests satellite layer specifically -->
  <tileUpdate>None</tileUpdate>
  <!-- No automatic tile refresh; ATAK uses cached tiles until manually cleared -->
</customMapSource>

Why this matters: The {$serverpart} variable enables parallel tile requests across Google's mt0-mt3 servers, dramatically improving load speeds. The lyrs=s parameter is the critical differentiator—change to lyrs=y for hybrid, lyrs=m for roadmap. This single-file pattern scales to dozens of sources by varying URL parameters.

Example 2: WMS-Based Map Source (FEMA Flood Hazards)

Web Map Service sources require additional parameters for proper coordinate transformation and layer selection:

<?xml version="1.0" encoding="UTF-8"?>
<customMapSource>
  <name>FEMA NFHL - Flood Hazard Zones (WMS)</name>
  <minZoom>5</minZoom>
  <!-- Higher minimum zoom: FEMA data is irrelevant at global scale -->
  <maxZoom>19</maxZoom>
  <tileType>PNG</tileType>
  <!-- PNG preserves transparency for overlay on other map sources -->
  <url>https://hazards.fema.gov/gis/nfhl/rest/services/public/NFHL/MapServer/export?bbox={$bbox}&amp;bboxSR=3857&amp;imageSR=3857&amp;size=256,256&amp;format=png&amp;transparent=true&amp;layers=show:0&amp;f=image</url>
  <!-- WMS export endpoint with critical parameters:
       bbox={$bbox} = bounding box in EPSG:3857 coordinates (automatically computed)
       bboxSR=3857 = source spatial reference (Web Mercator)
       imageSR=3857 = output spatial reference (must match for ATAK compatibility)
       size=256,256 = standard tile dimensions
       transparent=true = enables overlay compositing
       layers=show:0 = specifies which WMS layer to render -->
</customMapSource>

The technical challenge: WMS services return dynamically rendered images rather than pre-cached tiles. ATAK-Maps' XML translates between ATAK's tile-based requests and WMS's bounding-box paradigm. The bbox={$bbox} variable is automatically populated by ATAK's tile coordinate system—you never manually calculate extents.

Example 3: Overlay Map Source (GRG Terrain Shading)

Overlay sources add information layers atop base maps without replacing them:

<?xml version="1.0" encoding="UTF-8"?>
<customMapSource>
  <name>GRG - Google Terrain Shading Overlay</name>
  <minZoom>0</minZoom>
  <maxZoom>20</maxZoom>
  <tileType>jpg</tileType>
  <url>https://mt{$serverpart}.google.com/vt/lyrs=p&amp;hl=en&amp;x={$x}&amp;y={$y}&amp;z={$z}</url>
  <!-- lyrs=p requests Google's terrain shading layer (hillshading only, no base map) -->
  <overlay>true</overlay>
  <!-- CRITICAL: overlay flag tells ATAK to composite this semi-transparently
       over the active base map rather than replacing it -->
</customMapSource>

Operational impact: Overlay layers enable multi-source compositing. Combine Google Satellite base with terrain shading overlay and FEMA flood zone overlay simultaneously. Three data dimensions, one unified view. The <overlay>true</overlay> element is the enabler—without it, sources replace each other rather than stacking.

Example 4: GitHub Actions Validation Workflow

The repository's quality assurance is automated. Here's the actual validation workflow that prevents broken XML from reaching releases:

# .github/workflows/validate-maps.yml
name: XML Validation

on:
  push:
    paths:
      - 'maps/**.xml'  # Trigger only when XML files change
      - '.github/workflows/validate-maps.yml'
  pull_request:
    paths:
      - 'maps/**.xml'

jobs:
  validate:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      
      - name: Install XML validation tools
        run: |
          sudo apt-get update
          sudo apt-get install -y libxml2-utils
      
      - name: Validate all map XML files
        run: |
          # Iterate through all XML files in maps directory
          for xml_file in maps/*.xml; do
            echo "Validating: $xml_file"
            # xmllint performs well-formedness check
            xmllint --noout "$xml_file" || exit 1
          done
          echo "All XML files validated successfully"
      
      - name: Check required XML elements
        run: |
          # Custom validation: ensure critical elements exist
          for xml_file in maps/*.xml; do
            # Verify customMapSource root element exists
            if ! grep -q '<customMapSource>' "$xml_file"; then
              echo "ERROR: Missing customMapSource in $xml_file"
              exit 1
            fi
            # Verify name element exists for ATAK display
            if ! grep -q '<name>' "$xml_file"; then
              echo "ERROR: Missing name in $xml_file"
              exit 1
            fi
            # Verify URL template exists
            if ! grep -q '<url>' "$xml_file"; then
              echo "ERROR: Missing url in $xml_file"
              exit 1
            fi
          done

Why this automation matters: Every pull request is automatically validated. No malformed XML reaches production. The paths filter ensures validation runs only when relevant files change, conserving CI minutes. This is how ATAK-Maps maintains reliability across 30+ sources with community contributions.

Advanced Usage & Best Practices

Layer Redundancy Strategy

Never depend on a single map source. Configure ATAK with three tiers:

• Primary: Highest resolution current imagery (Google Satellite, Bing)
• Secondary: Government/authoritative sources (USGS, NAIP, NaturalResourcesCanada)
• Tertiary: Global fallback with guaranteed availability (OpenStreetMap derivatives)

Zoom Level Optimization

Custom Map Creation

For proprietary or internal map services, extend ATAK-Maps following the MOBAC XML Reference:

1. Identify your WMS/TMS endpoint
2. Determine spatial reference system (must be EPSG:3857 for standard ATAK)
3. Construct URL template with {$x}, {$y}, {$z} or {$bbox} variables
4. Validate with xmllint before submission
5. Test in ATAK with small zoom range before full deployment

Performance Tuning

• Server rotation: Ensure {$serverpart} variables use all available endpoints
• Tile format selection: Use JPG for photographic layers (smaller), PNG for overlays requiring transparency
• Cache management: Regularly clear and re-cache critical areas; imagery updates periodically

Comparison with Alternatives

The verdict: ATAK-Maps dominates for users prioritizing speed, reliability, and zero cost. Manual configuration suits organizations with dedicated GIS staff and unique source requirements. Commercial packages may appeal to entities requiring formal support SLAs, though they rarely match ATAK-Maps' breadth.

FAQ: Common Developer and Operator Questions

Q: Can I cache these maps for offline use? A: Absolutely. ATAK's native caching works seamlessly with ATAK-Maps sources. Browse an area while connected, and tiles cache automatically. For mission-critical operations, explicitly download regions beforehand. Cache storage location varies by Android version—typically /sdcard/atak/ or equivalent.

Q: Are these maps free to use commercially? A: The ATAK-Maps XML files are MIT Licensed—free for any use. However, the underlying map imagery has separate terms. Google, Bing, and ESRI layers have usage restrictions for commercial applications. Government sources (USGS, NAIP) are typically public domain. Always verify provider terms for your specific use case.

Q: Will more maps be added? A: Continuously. Submit requests via GitHub Issues. The automated release pipeline means new sources ship fast—often within days of validation.

Q: Why are some OpenStreetMap sources restricted? A: OSM tile servers implement usage policies that may block ATAK's user agent or high-volume requests. ATAK-Maps includes these for reference while exploring solutions—typically via alternate OSM mirrors or self-hosted tile servers.

Q: Can I modify these for my organization's internal maps? A: Yes—MIT License permits modification. Fork the repository, add your internal WMS endpoints following the XML patterns, and maintain your private distribution. Consider contributing generic improvements back upstream.

Q: How do I troubleshoot a map that won't load? A: Check three things: (1) Internet connectivity and URL accessibility via browser, (2) ATAK's map layer selector shows the source (confirming successful import), (3) Zoom level is within the XML-defined min/max range. Enable ATAK's debug logging for detailed error traces.

Q: What's the difference between TMS and WMS sources in ATAK-Maps? A: TMS (Tile Map Service) uses pre-rendered tiles at fixed zoom levels—faster, simpler, but less flexible. WMS (Web Map Service) renders custom images on-demand for any bounding box—slower, but supports dynamic layers and custom styling. ATAK-Maps includes both; TMS for speed, WMS for specialized data.
