Newsletter Volume 3, Issue 3

ComputaMaps is pleased to announce the opening of our latest corporate office in Brazil. With LTE spectrum auctions completed earlier this summer that include exacting coverage and access requirements tied to the FIFA World Cup in 2014, Brazil will be a first mover to the 4G technology in the region. “We see tremendous opportunities related to the LTE buildout in Latin America and the fact that 60% of operators plan to have their networks on air by the end of 2013,” said Albéric Maumy, managing director of ComputaMaps.“This new office builds on our existing Latin American presence and reinforces our commitment to the region.”

While most readers of this newsletter know ComputaMaps for our telecom “Planner” products, earlier this year we launched a DxM product line targeting other vertical markets with our quality 3D geodata including digital surface models (DSM), digital height models (DHM) and digital terrain models (DTM). Digital elevation models (DEMs) are derived from stereo satellite imagery, LiDAR and/or topographic contours and spot heights digitized from pre-existing cartography. Standard DEMs include:

  • DTM - Bald earth digital terrain models of the ground surface only, with optional transportation features (bridges, overpasses, elevated highways);
  • DHM - Digital height models of the ground surface overlaid with all buildings, elevated highways and bridges; and,
  • DSM - Digital surface models of the ground surface overlaid with all above-ground features (including man-made features and vegetation).

Our main article below explains how ComputaMaps geodata is used by customers in other vertical markets, including civil engineering, mining and for floodplain analysis by public and private sector organizations. As always, we hope you enjoy this edition of our newsletter and welcome your feedback.

Understanding Terrain is Fundamental: ComputaMaps DxM


While any RF engineer understands that a DTM and related clutter are fundamental for wireless network planning, they may not realize the roles these same products can play in other vertical markets. Before the computer age, national mapping agencies expended tremendous resources to generate contours for cartography given its importance for nation building. Now, using satellite imagery and other means, it is possible to have any region of the world at your fingertips. ComputaMaps recently launched our DxM product line of 3D geodata for markets not addressed by our Planner telecom products. The DxM products excel in applications for civil engineering, mining and hydrology/floodplain analysis.

Around the world, civil engineers need to understand the topography of their project's location, whether the structure being contemplated is a highway, power transmission lines, oil and gas pipeline, dam, etc. As with all ComputaMaps products, the quality and accuracy of the geodata is critical. If the simulations and calculations do not translate into the real world, then the effort is futile. Reliable DTMs, available in resolutions from 1-5m allow for an understanding of geospatial data critical to the planning and development of the essential infrastructure required to support a growing civilian population. ComputaMaps can support rural and urban requirements, including building polygons where necessary.

The geodata requirements of a mining operation vary depending on its status in the project lifecycle. The industry is highly regulated, and geodata has an important role to play in exploring for appropriate sites, as well as the safe development, regulatory compliance and operation of a subterranean or open pit mine. In the planning process, geodata can support environmental impact and hydrological studies, as well as hazard assessments and related infrastructure planning. Once the mine is operational, DxM data can be used to fulfill regulatory filings and in support of site remediation efforts. In this final use case, the data and related orthoimagery can be submitted as evidence that the former mining site has been returned to a state similar to the surrounding area.

The DxM suite of products also has a role to play in water management, including floodplain analysis and sea-level monitoring for coastal areas. A floodplain map delineates the area that can be expected to flood, typically once every 200 years. A DSM can be used to show a floodplain indicating the normal channel of water and surrounding land use, in conjunction with ground elevation contours, flood levels and floodplain limits. Flood routing and floodplain hydraulics are used to route runoff and external inflows through the civil engineered drainage system network of pipes, channels, storage/treatment units and diversion structures. ComputaMaps’ account team works with our public and private sector customers needing this information to ensure they receive fit-for-purpose data in the required format.

With the introduction of the DxM product line we are hoping to share our quality geodata – including an extensive off-the-shelf archive – with new customers needing accurate terrain data through our global sales and support offices. While ComputaMaps has introduced products for other markets, we also remain focused on telecom in support of the global migration to LTE.
