Abstract: Using Global Mapper to Develop Terrain Files For Hydraulic Analysis

GEI recently completed a two-dimensional hydraulic analysis for a hydropower client on the Ohio River. The client needed to fix a damaged portion of hydropower infrastructure and GEI was hired to design the infrastructure. There was concern about elevated velocities both during construction and post-construction (compared to existing conditions) by the hydropower owner, the contractor, the engineer, and agencies involved in river navigation and hydropower regulation. GEI needed to show the client, contractor, engineer, and regulators that velocities associated with the post-construction design and construction process were not significantly greater than the existing conditions. USACE's HEC-RAS software was used to estimate the velocities around the powerhouse for a range of river flows and three different terrain conditions: Existing, during-construction and post-construction. The velocities for the "during-construction" and "post-construction" conditions were compared to the "existing conditions" to quantify velocities for engineers and the contractor and their equipment (.i.e. barges) and to verify velocity deltas were negligible.

GEI used Global Mapper to develop the three terrain files (Digital Elevation Models). The "existing conditions" terrain file consisted of a Digital Elevation Model (DEM) created using LiDAR ground points and bathymetric survey points. Other portions of the dam that were not present in either survey were created using georeferenced shapefiles and known elevations for those areas. The "during-construction" and "post-construction" conditions were modified versions of the "existing conditions" DEM. They contained georeferenced shapefiles from engineered drawings with known elevations and other portions of the DEMs were modified by editing the point cloud. This included eliminating portions of the dam and replacing with a one-dimensional dam structure inside the model and creating a ramp along the river bank that will be used for access for construction vehicles and equipment.

Roel Nicolai

Roel Nicolai

Presented at: BMUC Amsterdam 2017

Speaker Bio

Dr. Roel Nicolai is a former Principal Geodesist with Shell International. He graduated in 1978 with an MSc in geodesy from TU Delft and worked in the Hydrographic Service of the Royal Netherlands Navy and Rijkswaterstaat before joining Shell in 1984. In 2014 he was awarded a PhD at the University of Utrecht on the subject of the mysterious origin of portolan charts, a subject he had studied as a hobby in his spare time for 10 years. Dr. Nicolai is currently semi-retired and occasionally engages in geodetic consultancy work.

Abstract: The Origin of Portolan Charts - A Medieval Geodetic Mystery

Portolan charts are realistic and detailed nautical charts of the Mediterranean and Black Seas which appeared suddenly in Italy in the 13th century. One of the most remarkable characteristics of these charts is their close resemblance to a modern map on the Mercator projection. Roel Nicolai analysed five charts as part of his PhD research using quantitative geodetic and statistical techniques. The results are surprising. The charts are demonstrated to be more accurate than has been assumed until now and are shown to be mosaics of five to ten sub-charts, some of which have considerable overlaps. Nicolai's analysis also shows that the map projection can only be an intentionally applied design feature of the original charts. These charts are not the simple, medieval maps they have been believed to be until now. They are quite sophisticated and cannot be medieval. Their origin must lay considerably further back in time.

Abstract: Vertically Challenged: Using Global Mapper to Create Vertical Shift Grids for Use in Geographic Calculator

Suncor has a few 3D custom coordinate systems for our assets in Northern Alberta. Up until the release of Geographic Calculator 2015, we could only use Geographic Calculator to convert to and from the horizontal part of the custom coordinate systems. Thus we had to use other, less efficient, methods for the vertical coordinate conversion. GC v2015 introduced "Custom vertical grid support in conjunction with Global Mapper" which meant I could use Global Mapper to create Blue Marble Grid files. GC can read the BMG files to perform the correct vertical coordinate conversion.

Bob Saunders

Bob Saunders

Sr. Geotechnical Engineer
Thurber Engineering Ltd.

Presented at: BMUC Calgary 2017

Speaker Bio

Bob is a Senior Associate and Geotechnical Engineer with Thurber Engineering Ltd. and has worked in the Calgary office for over 10 years. He has a B.Sc. in Civil Engineering from the University of Calgary (1981) and a Master of Engineering in Geotechnical Engineering from the University of Alberta (1989). He has over 30 years' experience in a wide range of geotechnical projects in Western and Northern Canada. Bob began his career in permafrost engineering and worked on several major northern pipeline projects including the Foothills Alaska Highway Gas Pipeline, the Norman Wells Pipeline, the Mackenzie Gas Project and the Alaska Pipeline Project. His Master's project was on wheel ditcher productivity in permafrost.

Mr. Saunders' main area of experience is with linear infrastructure projects (mostly pipeline), specializing in geohazard assessments and trenchless crossing design. Given the nature of linear projects to traverse long distances through diverse terrain and varied landforms, working in this field has inspired a need and a passion to embrace GIS and integrate its use into the geotechnical engineering workflow. Global Mapper has been one of the tools adopted by Bob and Thurber to assist with this integration. Bob has been an avid user of Global Mapper since Version 6.

Abstract: Slope Analysis for Linear Infrastructure Projects Using Global Mapper

Slope stability is one of the more important geohazards considered when assessing new linear infrastructure projects. The stability of natural slopes is affected by several factors; strength, groundwater conditions and gradient (slope angle). With the increased availability of processed bare earth LiDAR DEM for most major projects, slopes can be assessed in greater detail at a desk study level than previously possible.

Thurber Engineering Ltd. uses Global Mapper as our principal GIS tool for geohazard assessments. The workflows described in this presentation are focused on how we work with and manipulate bare earth DEM, as opposed to landform and landslide characterization, which are also done with Global Mapper. Several methods of analyses are outlined in this presentation, from simple slope gradient take-offs at points, to more complex proximity to steep slope analyses using buffers and perpendicular offset lines. Data preparation and visualization with custom slope shaders are also discussed.

Abstract: Creating Spatial Communication Through Integrated Mine Planning

Integrated mine planning allows mining operators, regulators, communities, and first nations to set and meet realistic performance goals for the reclaimed closure landscape. Topographical models are used in integrated planning as a framework to track the mining mass balance and the timing of material placement. However, 2D mapping outputs and paper reporting of the topographical models are not sufficient to bring clarity and alignment on the integrated planning process to operators, regulators, communities, and first nations. Mixed reality representation in a HoloLens application can bridge the gap, providing clarity and alignment on the long term performance goals for the closure landscape.

Abstract: Development of the iGlass Map Utilizing the GeoCalc SDK

Katalyst Data Management ( provides full life cycle subsurface data management solutions for seismic, well and project domains. Every step in the data management process is handled in-house, from data capture and verification, to data storage and organization, to marketing seismic data online. Katalyst's SaaS offering is securely managed over private cloud for both metadata and actual data files, amounting to several petabytes of data in multiple data centers for many reputed customers across the globe.

It is in the development of the iGlass map that Katalyst employs GeoCalc SDK (both the Java and .Net editions) from Blue Marble. This library is utilized in order to upload navigation information from external files in standard industry formats (such as SegP1, UKOOA among others). This is also utilized when users want to export selected seismic lines' navigation information into standard industry formats. For either operation (inbound or outbound), the users get a choice of coordinate transformation. As Katalyst stores spatial data in WGS84 datum, it often becomes necessary to apply transform for either input or output navigation data in other datum as suitable for different parts of the world such as NAD27 or ED50 or SAD69 or SIRGAS 2000. Katalyst clients feel assured when they know about use of IOGP-compliant GeoCalc for coordinate transformation.
