Over the past decade Real Time Kinematic (RTK) surveying with Global Navigation Satellite Systems (GNSS) has become common practice in geomatics. RTK surveying can allow people to achieve relative positioning with centimetre (cm) precision, however there are several important factors that need to be considered and thus a need for a good guide of best practices …
Total stations combine a number of technologies to achieve remarkable accuracy and reliability. The first, an extension of traditional transits and theodolites, is the ability to …
The total station can be used to survey in locations where you do not know the value of the point upon witch it is setup upon. This technique is often used when you have two points with known established coordinate values but are not in an ideal place to perform your survey from, or at times where you wish to progress further into an unknown survey region.
Mealy Mountains located in the southern portion of Labrador, is situated south of Lake Melville, north of Sandwich Bay and borders the Labrador Sea. The mountain range encompass over 26 thousand square kilometers of forests, tundra, wetlands, coastal barrens, lakes, beaches and bogs. This large remote region contains many scenic areas, many of witch I was fortunate enough to get to see while surveying various areas of the soon to be National Park.
Digital Terrain Modeling is the process of simulating or representing the relief and patterns of a surface with numerical and digital methods. It has always been an integral component to geology related fields such as geomorphology, hydrology, tectonics and oceanography but over the past decade has also become a major component to non geophysical applications such as GIS modeling, surveying and land use planning.
Terrain Models are derived from data represented by digital elevation models (DEMs) and can include shaded relief models, slope and aspect models, perspective scene generation, and drainage basin analysis (and other models).

When the total station is set up and level over the known point it will require another known point to help calculate the coordinate reference system that the unknown measurements will be measured with. That is to say that the total station will …
I recently wrote an article for GIM in their Perspectives Section, about why the geospatial community needs to improve people’s understanding of the relevance of geographic information and how this lead to forming GeoAlliance Canada. Read the full version here …
