GIS / Cartography

Cartography is the practice of creating maps or visual representations of geographic areas. Traditionally maps have always been created on paper, but since the wide spread use of GIS, has evolved more into digital formats. GIS, an essential tool for urban and resource planning, allows people to solve and model real world situations by incorporating spatial and tabular data.

LiDAR & Remote Sensing

LiDAR, a specialized remote sensing technique uses high precision GPS with an Inertial Measurement Unit to determine accurate surface locations. The resultant measurements consist of geographic locations that can be further processed to produce different spatial data products.

Surveying

Surveying is the technique, profession, and science of determining terrestrial positions of points and the distances and angles between them, these points are usually on the Earth’s surface, and most often used to establish maps and boundaries for property ownership.

Geomatics:

:a geospatial term that originated in Canada due to the similarity in origin with both official languages (English and French). It encompasses various tools and techniques from a multitude of geographic disciplines (geographic information systems (GIS), remote sensing, cartography, global navigation satellite systems (GNSS), photogrammetry, geography, surveying, and other related forms of spatial mapping).

Originally, I created tmackinnon.com as an online portfolio to help my career while studying Applied Geomatics Research at COGS but since then it has become a place on the web where I share information about geospatial resources using maps, literature, examples, photos and other interesting information that I have learned from my work experience or during some of my travels.

I have been fortunate enough over the past 20 years to work in almost all geomatics related disciplines that included a unique opportunity to travel all across North and Central America, allowing me to better appreciate geography.

Digital Terrain Modeling

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).

Real world example of slope and aspect

Digital Terrain Modeling – Aspect models

In digital terrain modeling the Aspect of a surface refers to the azimuth to which a slope is orientated. The aspect or orientation of a slope can produce very significant influences on it, so it is important to know the aspect of the plane as well as the slope.Together the slope combined with the aspect of the surface can virtually define the surface plane completely in digital terrain modeling

GPS Calendars

GPS or GNSS Calendars are different then traditional calendars that most of us are used to working with, yet they are pretty common these days due to the increased use of GPS equipment. Yet there is never one around when you need one, so if you find your self doing a lot of GPS field work like myself then you may notice that you will working in Julian Days & GPS Weeks frequently so will want to print off your own copy or use an online utility to help you out.Now one can easily calculate this info but I find it quicker to just resort to reference pages or use online utilities and here a few that I use ...

Example of an Aspect Map

This image is an Aspect Model that I derived from a digital elevation model (DEM) of Lismore, Nova Scotia. The aspect values of the slopes of the DEM are represented in the model by a 0-255 grey scale color ramp. Click here to learn a little more about Aspect Models and how the image below was created.

Leica GS20 PDM GPS Sensor & GIS DataPro Processing Software

The Leica GS20 PDM (professional Data Mapper) handheld GPS unit was a small GPS device that was included with the RTK GPS unit that was purchased for my LIDAR research project at the AGRG in 2003. The GS20 did not come with very good user guides so we created a brief user guide ...
