As the name implies, 2D CAD is used for drawing two-dimensional features which is best suited for traditional orthographic projections, such as plans, cross sections and elevations. QSP has been creating these types of 2D CAD drawings for utility companies over twenty two (22) years. In addition to the types of 2D CAD drafting services described above (Topographic and Profile Data Production) we also have experience in drafting 2D Site Plans, Construction Drawings, Resurvey Plans and Station Drawings.

In recent years, QSP expanded our drafting services to include 3D CAD as well. Through the use of a variety of different sources of information including exisiting records, assets photographs and LiDAR scan data we can create and/or update 3D intelligent models containing utility infrastructure (ie. equipment, piping, cables, etc.) with corresponding attribute information for both above and below grade assets. We are also proficient in producing isometric drawing files from the 3D models.

Garbage In, Garbage Out.  This phrase is true in GIS as well as the Records attribute information that is associated to it.  Today, more than ever, all companies should keep current and accurate records of their assets.  However, with enormous amounts of information being collected and input to a database, it is easy to lose track of the quality of record information that is contained within it.  As a result, the challenges  of creating, keeping and maintaining reliable records can be daunting.  QSP has the knowledge and experience to help our clients with this problem.

In addition, it was only recently when formal requirements were implemented for accurately recording the presence and location of utility infrastructure.  In 2011, CSA S250 – Mapping of Underground Utilities standards were introduced because many of the map records that exist are inaccurate, obsolete or in formats incompatible between utilities.  QSP understands these new requirements and respect the reasons why they are in place.

The types of Records Services that QSP provides to our clients include;

• Verification and correction of record mismatches and duplication
• Data entry
• Data updates
• Document scanning and imaging
• Database QA /QC
• Metadata creation

Over the years QSP has completed numerous GPS field data collection projects for our clients. By providing guaranteed quality through internally enforced processes, procedures and standardized deliverables it allows our clients to immediately integrate our field collected data into their GIS database. Our GPS Technicians/Technologists are all fully trained to use survey grade GPS equipment, recognize the potential impacts of environmental conditions and know how to optimize the quality of the assets or landbase features being collected, including;

• RTK status – RTK (FLOAT), DGPS, or GPS
• Satellite Geometry (PDOP, HDOP, VDOP, etc.)
• Number of satellites available
• Obstructions, line of site to satellites and any multipath influences
• Hardware damages

Depending on the project size, timeline and requirements QSP can perform field data collection exclusively or provide supplemental assistance to our client’s staff.

Since 2013 QSP Geographics has offered terrestrial laser scanning (LiDAR) services to our clients. We provide highly accurate, three-dimensional point cloud images that enables the end user to view, navigate, measure and analyze the 3D data using GIS and/or CAD software. To date, our LiDAR services have been used for Infrastructure and Utilities projects.
