The GIM 2016 Business Guide contains a series of interviews with key players and experts in the geomatics industry (including the article Trends in the Geomatics Market for 2016 by T MacKinnon), geospatial company listings, extensive product and market reports, an events calendar and more. It is distributed among subscribers of GIM International, visitors of international trade shows throughout the year and is available free as a downloadable online edition.
Bathymetry is used to measure water depths to help model physical underwater terrain found beneath large bodies of water. Similar to the same way that LiDAR models are represent 3D features (or relief) of land terrain, bathymetric maps illustrate the terrain or land that is located under large bodies of water.

Recently, someone contacted me looking for information on where they could find topographic map data for the Thunder Bay area, so I assumed that they must have already checked the Canadian data page, so suggested that they check out the Ontario Basic Mapping web site (OBM).
The Ontario Basic Mapping (OBM) site by the Geography Network is a great online resource with simplistic interactive interface that provides users tools to create customized map views and the ability to download various topographic base mapping data for the entire Province of Ontario. The site contains GIS layers created from 1:10,000 base maps from the Ontario Ministry of Natural Resources that people can download including layers for transportation, water, municipal, elevation, parks and conservation areas.
Today I have included more information about the OBM including a video on how to download free topographic data from the site.
Critical Questions To Ask About Laser Scanners
Choosing 3D laser scanners should be a quantitative process with significant ramifications for your project deliverables, project workflow, resources, personnel, time and cost. The initial step is to define your deliverable’s specifications and the necessary workflow to create the 3D model, and then match these with the laser scanner specifications.
Before making the final decision to invest in laser scanning technology, be sure to ask the following seven questions to ensure that you have a clear understanding of how the 3D laser scanner specifications, workflow and upfront cost will impact your long-term operations and productivity.
This free digital book by Robert Gardiner, a laser scanner and 3D computer modeling specialist helps answer seven must-ask questions will help you choose the right laser scanner for your business.

The RADARSAT-1 Story: A Canadian Satellite
The RADARSAT-1 Story: A Canadian Satellite is a 136 page book about the creation and operation of the first Canadian commercial Earth observation satellite, RADARSAT-1. RADARSAT-1 utilized synthetic aperture radar to obtain images used to help better manage natural resources and monitor climate change. RADARSAT-1 was featured on the back of the Canadian 100 dollar bill in 2004.
The RADARSAT book includes an extensive gallery of photos and images and documents how the RADARSAT program became an important part of Canada’s space history. You may also want to download some of the freely available RADARSAT-1 data.
Synthetic-aperture radar (SAR) is a type of radar data that can be used to generate 3D images of terrestrial object, such as topography. SAR images have multiple applications in remote sensing and topographic mapping of surfaces.
The images are created from radio pulses that are transmitted towards a target area, then received and recorded. The pulse waves are usually transmitted and received with a single beam antenna, and the wavelengths used can be anywhere from a meter to a few centimeters.
The book Land Applications of Radar Remote Sensing demonstrates the use of SAR with topography and land cover. The authors go into extensive details on speckle and adaptive filtering, as well as digital elevation models (DEMs) and terrain modeling.

QMap – A field data collection program using QGIS
QMap is a field data collection application built using QGIS and python plugins. It is very similar to QGIS but with an interface that makes it easier for most people to use for data collection in the field and was designed to work with windows based tablet devices. Custom forms are built using Qt Designer and follows a convention based approach in order to save configuration. The application also supports QGIS project files (.qgs) so that you can easily use it with your QGIS desktop mapping projects.
To download the application or get more info about QMap go to http://nathanw2.github.com/qmap/
