Slope failures along highway corridors can create serious safety, environmental, and financial risks. When erosion, instability, or drainage issues emerge, agencies often need to make urgent decisions with limited data, all while managing traffic impacts in challenging site conditions.
RPM helps reduce that uncertainty by delivering high-resolution terrain models with full embankment coverage, allowing engineers to evaluate slope geometry, drainage pathways, and erosion features using a reliable, defensible baseline. Our approach captures detailed information without placing crews on unstable slopes or relying on sparse data from conventional surveys.
RPM’s patent-pending mobile mapping configuration features an extendable LiDAR system that reaches beyond the vehicle’s wheelbase, providing a clear line of sight to downward embankments and backslopes. This design enables detailed capture of roadside terrain that is frequently missed by conventional vehicle-mounted systems or requires time-consuming and higher-risk field surveys.
The result is a clearer understanding of slope conditions and stronger data to support faster, more confident mitigation planning.
How RPM Supports Slope Assessment & Mitigation:
- Detailed slope and embankment surface models, including backslopes and difficult-to-access terrain
- Provides critical data to aid identification of high-risk areas for erosion, scour, or potential failure
- Repeat mapping to monitor change over time and detect emerging trends
- Reliable geometry for geotechnical review and mitigation design
- Improved safety by minimizing on-slope field exposure and traffic-side survey work
- Accurate baselines for remediation, stabilization planning, and documentation
Mobile Mapping
To support slope and embankment modeling across infrastructure corridors, our patent-pending
mobile mapping system can rapidly capture terrain, grades, and surface conditions far faster than conventional RTK or total station methods while collecting
significantly denser spatial data.
This approach enables critical earthworks and stability features to be documented efficiently while maintaining the level of accuracy required for design validation, risk assessment, and engineering workflows.

FAQ
Welcome to FAQs
Please select a frequently asked question from the menu below.
How does RPM help reduce uncertainty in slope assessment?
RPM’s patent-pending extendable, truck-mounted LiDAR system reaches far beyond the vehicle’s wheelbase, capturing dense, continuous coverage of slopes and embankments; areas that are often incomplete or lack detail when surveyed using traditional methods or standard vehicle-mounted systems.
By collecting more complete data upfront, RPM minimizes the need for interpolation. As a result, final models and derived products are grounded in real measurements rather than estimates, delivering greater accuracy, increased confidence, and more informed decision-making for clients.
Can RPM help identify potential slope hazards?
Yes. RPM provides high-resolution terrain data that enables teams to identify potential slope hazards, including areas at risk of erosion, instability, or failure. Its detailed terrain models also support drainage analysis, helping engineers understand how water moves through the area. By revealing both surface conditions and drainage patterns, RPM equips clients with the insights needed to proactively assess risk and make more informed decisions.
Is RPM able to help monitor slope changes over time?
Yes. RPM can perform repeat data collection to monitor slopes over time, capturing high-quality datasets that enable accurate change detection and trend analysis.
While RPM provides the data and supports identifying where and how conditions are changing, we do not perform engineering analysis to determine why those changes are occurring. This allows clients and their engineering teams to apply their own expertise to interpret the results and make informed decisions.
How does RPM improve safety during slope assessment?
RPM captures data quickly using Mobile Mapping, RPAS-based LiDAR, and photogrammetry, significantly reducing the need for field crews to work on or near hazardous slopes, embankments, or active roadways. By operating from within the vehicle or at a safe distance, RPM minimizes exposure to unstable terrain and traffic while eliminating the need for lane closures.
