This paper provides a critical and objective review and assessment on the Wyoming LiDAR Data Portal – What is it? How did it get to its current point? What can it do for current users? What can it do for potential future users? In providing a viewpoint on the advances in data access, we also examine its current limitations.

What Is the Wyoming LiDAR Data Portal?

The Wyoming LiDAR Data Portal is an open-access data portal and service that is operated by the Wyoming Geographic Information Science Center (WyGISC) – a unit of the University of Wyoming School of Computing. The Portal is a one-stop shop for filtering and retrieving LiDAR (light detection and ranging) elevation data and associated derivative products collected in the state of Wyoming.

The portal was launched after a 2023 budget appropriation from the Wyoming state legislature that funded the development of a Digital Terrain Model (DTM) and a two-foot contour dataset from topographic LiDAR obtained via the USGS 3D Elevation Program (3DEP).

Why the Wyoming LiDAR Data Portal Matters for Mapping and Planning

LiDAR uses laser pulses to measure distances from an aircraft to the ground, generating detailed elevation models. In a state with varied terrain — from high plains to mountainous regions — such data has practical relevance.

Sample Use Cases:

• Flood hazard assessment and modeling
• Transportation and infrastructure site evaluation
• Forest and wildfire management planning
• Watershed and hydrologic modeling
• Environmental monitoring and analysis

Inside the Wyoming LiDAR Data Portal: What You Can Access

Phase one of the project resulted in the Wyoming LiDAR Hub, a publicly available site offering multiple datasets and tools:

1. Statewide Digital Terrain Model (DTM)

• Built from standardized LiDAR datasets.
• Useful for terrain and slope analysis.

2. Two-Foot Contour Dataset

• Facilitates detailed topographic planning.
• Supports preliminary engineering designs.

3. Data Download & Explorer Tools

• Interactive map allows users to select and download data.
• Organized by project boundaries, collection dates, and regions.

All files are available in common GIS formats. However, users should be prepared to handle large datasets and have access to appropriate software such as ArcGIS or QGIS.

Development and Data Standards

WyGISC developed the datasets in collaboration with Woolpert, a geospatial services provider. The U.S. Geological Survey (USGS) collected the original LiDAR data through its 3DEP program to ensure alignment with national elevation standards.

Example: Floodplain Planning in Riverton

In communities like Riverton, where flood risks are a concern, planners can use LiDAR-derived models to simulate water movement and identify vulnerable areas. This can improve preparedness and influence land-use planning. Still, accuracy depends on how well LiDAR data is integrated with local hydrologic and soil models — a challenge for less experienced teams or under-resourced agencies.

Current Limitations of the Wyoming LiDAR Data Portal

While the portal represents a significant step forward, there are nevertheless several practical limitations to consider:

• Data Complexity: LiDAR files are large and require technical skill to process.
• Incomplete Coverage: Although the datasets aim for full statewide coverage, in practice, not all regions are equally represented in terms of resolution or update frequency.
• Learning Curve: First-time users unfamiliar with GIS platforms may face a steep learning curve.
• Tool Limitations: The online tools are still in development and may lack advanced analysis functions.

What’s Next for the Wyoming LiDAR Data Portal?

As outlined in the University of Wyoming’s May 2025 update. Phase Two of development will focus on:

• Adding more localized and recent LiDAR data
• Developing new derivative products (e.g., vegetation models)
• Enhancing data explorer and download functionality
• Engaging local agencies and researchers for feedback and partnerships

Getting Started: Practical Steps

For users interested in exploring the portal:

Step 1: Visit the Portal

You can access the full collection of statewide LiDAR datasets directly through the Wyoming LiDAR Data Portal — no login or registration required.

Step 2: Use the Explorer

Zoom in on areas of interest and click tiles for dataset details and download options.

Step 3: Select Data Type

• Choose the DTM for terrain modeling.
• Choose contours for planning or design requiring elevation context.

Step 4: Prepare Your Tools

Ensure you have access to GIS tools capable of handling large geospatial datasets.

Conclusion: Evaluating the Wyoming LiDAR Data Portal’s Impact

The Wyoming LiDAR Data Portal is a promising public data resource that supports a wide range of environmental, engineering, and research applications.

For professionals and organizations already working with geospatial data, it offers a convenient way to supplement existing datasets. For new users, the benefits may require an investment in software and training.

Ultimately, it’s a foundation — not a silver bullet — for better spatial understanding in Wyoming.
