Existing line projects required acquisition of nadir and oblique digital video, nadir Infrared, high-resolution stills and LiDAR data. Processing resulted in delivery of Digital Terrain Models, Geo-referenced Mosaics and associated high-resolution images, Plans depicting pertinent topographic features in CAD and profiles. As an extension of this work, Optimal Geomatics undertook data analysis for some of the existing lines to identify danger trees in the proximity of the ROW.

New line projects required acquisition of nadir and oblique digital video, oblique high-resolution stills and LiDAR data for the proposed corridors 0.25 - 0.5 miles wide. After detailed analysis by Optimal Geomatics, this data was presented as Digital Terrain Models, CAD Plans, Geo-referenced Mosaics and other high resolution still photos.

This project required acquisition of nadir and oblique digital video, oblique high-resolution stills and LiDAR data for an existing power line ROW. Data was provided depicting left, right and center line profiles extracted from a DTM, detailed CAD plan drawings in MicroStation format, Geo-referenced Mosaics with associated still images, video clips, and landowner information.

These projects required acquisition of nadir and oblique digital video, oblique high-resolution stills and LiDAR data for a number of existing power line ROWs. Detailed engineering design data was provided in electronic format including DTMs, detailed CAD and P&P drawings in MicroStation format, Geo-referenced orthophotos and associated high resolution still images and video clips.

This project required complete mapping and records for the 33 and 132 kV network including production of overhead line profiles. Clearance checking was provided for ground and adjacent vegetation / structures. The project also included a complete engineering analysis of the entire network as surveyed. Deliverables were compliant to company and national transmission line engineering specification. Delivery of all data was in a format fully integrated into a desktop GIS and overhead line design system.

This project required an aerial survey for a proposed line, production of overhead line profiles, location of structures, stringing of conductors and completed engineering analysis and design. Digital video of the corridor was also required.

This project involved mapping to GIS accuracy, then entire EKPC overhead transmission line system and substations. Deliverables included GIS data in ESRI ArcView format.

This project required Optimal Geomatics to provide ACAD Map files of the COMED system showing locations of structures, attachment points and structure orientation. Optimal Geomatics provided Digital Downward and Forward Looking video, IR and high-resolution still images of the line. Deliverables included locating all structures, lines, fences, and road crossings, completing a customized attribute table, detailed anomaly reports, and providing data in a customer specified format. All data was then converted to SmallWorld.

This project required Optimal Geomatics to provide digital video, IR and high-resolution still images of 12,000 structures in the client's service territory. Deliverables included locating all structures, supplying the digital images in CD format and providing a written report of any anomalies with location and images. The data was integrated into an ESRI GIS.

This project required Optimal Geomatics to provide digital downward and forward looking video, IR and high-resolution still images of all structures in the line. Deliverables included locating all structures, completing a customized attribute table, detailed anomaly reports, and providing data in a customer specified format. Many potential anomalies were discovered and reported in the initial analysis. Data and imagery were integrated into the EPRI Power Line Management System.

This project required Optimal Geomatics to provide digital DTV, IR and high-resolution still images of all structures in the line. Deliverables include supplying original media, a processing platform and training for WFEC personnel. The data was integrated into an ESRI GIS.

This project required Optimal Geomatics to perform high altitude and low altitude aerial mapping to deliver the specified data set for use in Altalink's GIS system. The low altitude mapping data was acquired using Optimal Geomatics' proprietary Vid/Tracker system mounted on a Jet Ranger helicopter. The imagery acquired included downward looking full motion video and high resolutions color photographs. From this data, using proprietary software Optimal's technicians were able to determine accurate structures location and using software developed specifically for the project, were able to determine comprehensive structure attributes that included construction details and field proximity.

The second portion of the project involved using photogrammetry to map a 1600m wide corridor with color digital imagery. This imagery is used in the GIS land base to show structure locations and access points. All data was delivered in ESRI ArcMAP format.

For this project, Optimal Geomatics merged data from its exclusive Vid/Tracker system in conjunction with the client's vector mapping data. The two data sets were compared and Optimal determined up to data structure data and produced mosaic imagery of the ROWs for the client to integrate into GIS.

Optimal utilized the data it derived from imagery and other data sources to undertake a Class Location study of the pipeline ROWs. Hard to Evacuate Areas (HEAs), High Consequence Areas (HCAs), Outdoor Congregating Areas (HCAs) were defined and Class Location was determined using a customer-specific algorithm that works on a sliding mile concept. Deliverables included a structure database, Class Location polygons and imagery which the client integrated with its GIS.
