Field Survey

e-Logics is focused on client relationships where we can add value. We have therefore designed and mastered a number of core competencies to realize tangible benefits. One of these competencies is to capture inventory and assets of infrastructure spread over large territories. Our strength lies in our ability to provide information in a more efficient, rapid, safe and cost-effective manner.

Our systems and processes are designed to capture and assess inventory and infrastructure assets and features managed by:
- Metropolitan Councils and Municipalities
- Transportation authorities (road, railway, public transport, etc.)
- Utilities (telecommunications, electricity distribution, etc)


Data collection services and tools include a geo-referenced land videography system. This open scalable solution relies on the use of high resolution digital cameras (IEEE1394), positioning systems (GPS receivers, DMI, IMU) and photogrammetric features to create a unique spatial referenced data collection tool.

 

The data collection process is split into two phases:

Phase 1 involves geo-referenced image data collection from a road/rail vehicle or via aerial survey. Image data collection surveys are based primarily on the use of hardware (1600 x 1200 pixel resolution cameras, GPS, computers etc.) and software components installed on a rail or road vehicle travelling at traffic speed. The image capture frequency can by specified as per requirements, whether it is on the basis of distance (e.g. 1 image every 5 meters) or fixed frequency (e.g. 5 frames per second).

 
 

Phase 2 involves desktop data extraction. The data extraction entails the use of software to view and interpret geo-referenced digital imagery and identify assets.

Asset inventory information is extracted as per the client requirements. Any visible element on captured imagery can be positioned geographically and measurements (distance etc.) calculated.
 
 

The main fields of application include the following:

  • Video logging
  • Inventory of roadside furniture and assets
  • Road lane measurements
  • Railway infrastructure survey
  • Inventory of forest roads
  • Inventory of electric distribution networks and/or telecommunications infrastructure
  • Inventory of municipal utilities
  • 360-degree imaging
  • Centerline data capture and inventory of data relevant to emergency response programs
