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 …
Using acronyms and abbreviations is commonly practiced in the Geomatics industry and most of the time people just assume that everybody else knows what every acronyms and abbreviation stands for. Well that is obviously not the case most of the time and over the years I have created myself a little digital cheat-sheet of geomatics acronyms and abbreviations that I use with my work in my writing.
The design of the spatial database is the formal process of analyzing facts about the real world into a structured model. Database design is characterized by the following phases: requirement analysis, logical design and physical design. In more common terms, you basically need a plan, a design layout and then the data to complete the process.
GIS Spatial Modeling is the process of modeling, examining, and interpreting geographic data. It uses a set of defined methodology and analytical procedures to derive information with spatial relationships between geographic phenomena. It can be useful for evaluating suitability and capability, for estimating and predicting, and for interpreting and understanding real world situations. …
A digital elevation model (DEM) or sometimes referred to as a digital terrain model (DTM) is a quantitative representation of the topography of the Earth. DEMs are used as a source of elevation (and to create other digital terrain models) for many different purposes
A color shaded relief (CSR) model utilizes chromo stereoscopic techniques to help emphasize the depth of the Z dimension from traditional shaded relief models that already portray the presence of an elevation difference.
Canadian GIS and Geomatics Resources is an extension of my web site that I started back in 2005 after I noticed that there was a real need to have one good place on the web to help find Canadian geospatial resources. The site helps provide others with …
Geographic information systems commonly known as GIS has become a rapidly growing technological field that allows Geomatics Specialists to solve and model real world situations by incorporating digital spatial and associated tabular data. It is often defined as a comprehensive computerized information system made up of hardware, specialized software, spatial data and people to help manipulate, analyze and present the information used for storing, manipulating and analyzing spatially indexed information.
GIS operates on many levels and over the past decade has become an essential tool for most urban and resource planning and management organizations. On the most basic level, GIS can be used for simple digital cartography, to create various types of maps.
However the real power of GIS is through its abilities to use both spatial and statistical methods to analyze attribute and geographic information together. The end result of such an analysis can be vast amounts of derivative information, interpolated information or prioritized information.

GIS technology can be used for scientific investigations, resource and utilities management, modeling, assessments, development planning, cartography and route planning and many other applications.. Some of these and other aspects of the GIS field are currently covered on this web site including projects related to spatial database modeling, Geostatistical spatial modeling, mobile mapping, cartography, and interactive web mapping.
Below are some examples of GIS from a few of the many GIS based projects that I have been involved with over the past few years. The links are to PDF versions of papers, presentations and or manuals related to GIS, I have many more, if anybody is interested in a particular topic then feel free to let me know, as I may have a document available related to that topic.

Cartographic Map Design
Cartography or map making is the practice of creating maps or visual representations of a surface, as you would see it from above it.
Traditionally maps have always been created using pen and paper, but since the introduction and wide spread use of geographic information systems (GIS) better computers, and the Internet cartography practices have evolved more into a variety of digital formats.
Most maps today are now generated using map software that falls into one of three main types; GIS, CAD, or specialized map graphic design software.
These days many consider cartography to be more precise, thanks to advancements in computer technology, satellites and GPS. Earlier maps, though, were created by hand using simple instruments with mathematical equations.
Ptolemy, a Greek cartographer from the 14th century derived a projection consisting of set of geographical coordinates to map the Roman Empire. Eratosthenes, another Greek cartographer was the the first person to determine the circumference of the Earth. Many centuries later, and still some of their techniques are still used by cartographers in map making.
My cartography experience began during my time studying geology at Acadia University. I was involved in several geology field mapping courses creating geology maps. Then while studying remote sensing techniques at COGS, I started to use various GIS and graphic design software packages to create mapping products. These days I create maps on a daily basis for the majority of projects that I am involved in.

Canadian Cartographic Association
The Canadian Cartographic Association (CCA) was founded in 1975 with the aims of promoting interest in maps and related cartographic materials, furthering the understanding and knowledge of maps, and advancing education in cartography through the use of maps.
Three decades later, the aims remain the same, although the CCA now considers its constituency to extend beyond Cartography to embrace closely related fields such as GIS. Membership is open to anyone with an interest in any aspect of mapping and members are drawn from the ranks of government, industry, and education, and from the general public.
At the 2018 CCA annual general meeting I was elected to the position of Vice President. Membership is open to anyone in the geospatial community, both individuals and organizations interested in cartography. The core group that makes up the CCA area great bunch of people that are constantly encouraging more people to get involved. Click here, to find out how to join the CCA
Much of the material in the cartography part of my website originated from my original online portfolio that I used to further my career.
Since then it has morphed into more of a resources section related to remote sensing that includes helpful information about cartography and maps, including various related books, images, maps, data and much more.
