Utilizing Aerial Mapping Technology for Landfill

Robinson has extensive experience supporting Landfill Operations with the utilization of Aerial Mapping Photography, Low Altitude Mapping Photography (LAMP), and Light Detection and Ranging (LiDAR)

ATLANTIC CITY UTILITY
AUTHORITY LANDFILL

ATLANTIC-CITY

ROBINSON was contracted to obtain new black & white aerial mapping photography, perform aero triangulation and compile 50-scale topographic mapping with one-foot contours for approximately 225 acres of the ACUA Landfill, near Atlantic City, NJ.

As part of this project, Robinson identified and field-located existing surface utilities/drainage features, within the project limits, including manholes, catch basins, etc., including material types and sizes of utilities.

These utilities included but were not limited to storm and sanitary sewer mains, aerial transmission lines, fiber optic lines and utility mark-outs.

ENCAP PROJECT

ENCAP

ROBINSON was contracted to obtain new color aerial mapping photography, perform aero triangulation and compile 30-scale topographic mapping with one-foot contours for approximately 2.5 sq. miles of the Hackensack Meadowlands in Bergen County, NJ. This landfill area was designated to be at capacity and suitable for capping and redevelopment.

SPROUT BROOK LANDFILL

ROBINSON was contracted to obtain new color aerial mapping photography, perform aero triangulation and compile 30-scale topographic mapping with one-foot contours for approximately 2.5 sq. miles of the Hackensack Meadowlands in Bergen County, NJ. This landfill area was designated to be at capacity and suitable for capping and redevelopment.

PENNSAUKEN

SPROUT-BROOK-LANDFILL

ROBINSON is annually contracted to obtain new black & white aerial mapping photography, perform aero triangulation and compile 100-scale topographic mapping with two-foot contours for approximately 150 acres of the Pennsauken Landfill.

GLOUCESTER

GLOUCESTERL

ROBINSON is annually contracted to obtain new black & white aerial mapping photography, perform aero triangulation and compile 100-scale topographic mapping with two-foot contours for approximately 210 acres of the Gloucester Landfill.

Aerial Mapping Technologies

What is LAMP?

LAMP is a helicopter based camera system. It utilizes a Wild RC-30 precision aerial mapping camera with Forward Motion Compensation (FMC) and stabilized in the three axes using a gyroscopic mount. The combination of the slower forward speed of the helicopter and the use of FMC allows for unparalleled clarity in the photographic image. The improved image clarity allows for ground control points to be observed much more closely than with conventionally flown photography.

Utilizing LAMP is the safest technical approach to create a new Digital Terrain Model of the hard paved surfaces and the right of way corridor. It keeps surveyors out of harm’s way while at the same time using licensed surveying professionals to collect required ground data for a fully integrated DTM. LAMP makes use of high resolution cameras to create crisp final results and it is highly useful to the following kinds of surveying projects, among others: landfill operations, debris management, street planning, power line organizing and patrolling, pipeline preparing and patrolling, park organizing, subdivision arranging, and railroad preparing and patrolling.

LiDAR Complements LAMP Technology

Light Detection and Ranging (LiDAR) is a remote sensing technology which uses laser light pulses to measure the distance and the ground. This technique can be used to determine the elevation of an area. The LiDAR sensor on the aircraft captures the light intensity that is returned. Since LiDAR data can penetrate vegetation, there are two products that can be created from LiDAR including the first return file which is a combination of all data classes received from the first-return of each laser pulse and attributed to the canopy surface and the bare earth file which is the data from only the last return of each pulse and attributed to the ground surface. LiDAR can be used to estimate debris volumes post-event if there is recent pre-event LiDAR data for the same area.

LiDAR & photogrammetric mapping complement each other in that where photogrammetry is better suited for a quick, qualitative analysis in determining the identity of surface features, LiDAR data allows for large areas of 3-dimensional data to be collected in a very cost effective manner.
