Dec, 2003       USA, Arizona, Phoenix       

Airborne Laser Survey of 470 km of 230 kV and 500 kV power transmission lines located in Phoenix and adjacent area. The purpose of implementation of the survey is uprating, reconstruction of power transmission lines as well as identification of critical clearances of power lines. OPTEN’s Data Processing Group delivered the following products: feature coded LiDAR data for use in TL-Pro, orthorectified digital imagery, forward and downward looking video in MPEG format, spreadsheets with calculated temperature of the conductors and catenaries values.

Oct, 2003       Slovenia       

Realization of airborne laser survey of 50 km of power transmission lines comprising Formin - Ljutomer and Ljutomer - Lendava with derivation to Ormoz. The deliverables included processed laser data in PLS-CADD, electronic model of line in ALTEX OBSERVER format, specialized database on geoinformation platform ArcView as well as sheets of features and parameters of OPL.

Oct, 2003       Slovenia       

Airborne laser survey of 130 km corridor for 400 kV Cirkovce - Pince transmission lines construction. The final products comprised feature coded data in PLS-CADD, the model of power line in proprietary ALTEX format, planimetric drawings of anthropogenic objects in ACAD, format DXF, and in addition to it the Client was transmitted PLS-CADD project files.

Oct, 2003       Slovenia       

Implementation of airborne laser survey for the design of 48 km of 400 kV Bericevo - Krsko transmission lines for IBE, the leading power engineering and construction company in Slovenia. As a result of the implemented work the following deliverables were handed over: fully processed LiDAR data in PLS-CADD, electronic model of line in ALTEX OBSERVER format, DXF files and manageable PLS-CADD project files.

Jul, 2003 - Sep, 2003       USA       

Survey of 138 kV power transmission line in the USA. The survey objective was to acquire accurate and updated information for line reconstruction.

The deliverables included fully processed (feature coded) LiDAR data in PLS-CADD, high-resolution digital orthophoto mosaics, oblique high-resolution pictures of all structures, digital videos of right-of-way and alternative routes, and weather monitoring data along the route for sag-tension analysis.

As part of the contract, using special procedures and software developed in-house we significantly reduced the size of LiDAR data in PLS-CADD while preserving the accuracy of the original dataset. This allowed us to prepare manageable PLS-CADD project files that included little redundant information.

May, 2003 - Jun, 2003       Russia       

Survey of 870 km of 110 kV and 220 kV overhead power transmission lines.

The project objective was to survey existing power lines and produce detailed and updated documentation as well as to register right-of-way land use.

Using airborne laser survey data we performed sag-tension analysis, identified critical clearances, produced 3D vegetation maps, created high-resolution digital orthophoto map and ArcView GIS of the transmission network.

Apr, 2003 - May, 2003       Europe       

Survey of 700 km of overhead power transmission lines.

110 kV, 220 kV and 400 kV lines.

This survey was conducted as extension to projects we performed in 2002 (please refer to description below).

Apr, 2003 - May, 2003       Europe       

Airborne laser survey and mapping for power engineering and construction company. For 90 km of transmission lines design and construction our Client required highly accurate three-dimensional data on true ground relief and objects on the surface.

Deliverables production included detailed objects recognition and feature-coding of data, orthophoto map production. The final product was delivered ready to use in PLS-CADD.

Feb, 2003 - Mar, 2003       New Zealand       

Survey of 1,800 km of overhead power transmission lines. This survey was conducted as extension to 2002’ contract. (please refer to description below). In pursue of our Client’s requirements, in 2003’ deliverables we switched the format of video data to coordinates and time annotated digital video in MPEG format, changed some parameters of orthophoto map production and increased data density on pole lines.
