1 LiDAR Engineering and Design Applications Sample Data

2 High density LiDAR will return points on any visible part of a structure. Modeling of Existing Structures 2

3 The distance between any two positions within a LiDAR point cloud can be measured with a high level of relative accuracy Ft Ft Ft Ft. Relative Measure 3

4 Elements within a point cloud can be classified and separated. Notice how different colors are used to represent different parts of the bridge. Trusses Deck Railing Piers Point Classification 4

5 50.6 Ft Ft Ft Ft Ft Ft. LiDAR returns are recorded with an intensity value. This can be thought of as the brightness of the object. The result is a grayscale type image. LiDAR Intensity Image 5

6 Notice that this is the same area as in the image before Ft Ft Ft Ft Ft Ft. Using computer software to generate best-fit models, features such as buildings can be vectorized to create line work for design projects. Vectorized Features 6

7 Custom oblique photography can be added to your project to reveal hidden details and verify the origin of LiDAR returns. Notice that this is the same area as in the two images before. See our Photography Sample Oblique Photography 7

8 Power lines and towers can be vectorized from LiDAR data also. See our Corridor Mapping Sample Vectorized Features 8

9 Accurate elevation contours can be created for your entire project area using LiDAR data. See our Topo & Contour Sample Smoothed Elevation Contours Labeled On DEM 9

10 LiDAR data can be used to calculate material volume against a reference plane. When before and after LiDAR is collected, highly accurate volume change calculations can be made. See our Volume Calculation Sample Volumetric Analysis 10

11 PAR logs an in-flight static control session using a survey grade GPS unit. The ground control for this process is monumented and tied to NGS control near the job site. Also, an OPUS solution is processed after the flight, and RTK/VRS ground truthing control is collected. NGS Monument Ground Control 11

12 Technology PAR utilizes the latest Aerial Photography and LiDAR technology from Leica Geosystems. LiDAR Photography Utilizing the Leica RCD 30, PAR can capture highly accurate multispectral aerial imagery at various resolutions ranging from 1 to 1 GSD. Through the implementation of high rate airborne GPS and IMU data collection, the need for ground control is significantly diminished, and for mapping grade projects, eliminated altogether. Utilizing systems such as the Leica ALS70, PAR can collect high density elevation data with a point spacing ranging from 5 to 50 pts/m 2. This data can be used for detailed 3D modeling of the ground and surface features. LiDAR allows for detailed surface mapping in areas where access prohibits other cost-effective means of data collection. Dense woodlands, hydrological basins, and busy cities are easily captured using LiDAR, during the day or even at night. Industry Applications With LiDAR and aerial acquisition, the possibilities are vast. Many industries have realized the power of this technology and its ability to save them time and money while maintaining unbeatable accuracies. Data Applications: Aerial Facility Inventory Construction Progress Monitoring Disaster Damage Assessment Elevation Contour Lines GIS Analysis Levee Elevation Data Pipeline/Power Line/Railroad Corridor Mapping Planimetric Mapping Route Selection Support Survey Support Volumetric Calculation Watershed Analysis Three-dimensional surface modeling has countless applications. Surface models are used for construction planning and design, hydrological models, digital canopy (tree height) models, geological studies and much more. Complete Service Planimetric Mapping From producing inputs for you next CAD project, to full CAD basemap development and GIS analysis, PAR can get the job done. CAD Basemap The PAR team works together with our clients to produce a completely customized product that fits the end user s needs. Elevation Contours The staff at PAR has extensive experience in surveying, GIS, mapping, and CAD. PAR is a full service company for geospatial solutions. Cost Effective PAR can save you time, and money. When site access and ground conditions are slowing progress for time sensitive work, PAR can get the job done with proven speed and accuracy. Our company structure is lean and built to operate with the highest efficiency; therefore, we can tackle projects as small as 50 acres while remaining cost effective. The end result is a fast, accurate, and reliable product. 12
