Geomatics Acronyms and Abbreviations

Canadian Geomatics Acronyms and Abbreviations

Geomatics Acronyms and Abbreviations

Geomatics has become a pretty common term in Canada lately and includes many different disciplines such as geographic information systems (GIS), remote sensing, cartography, land surveying, global navigation satellite systems (GNSS), photogrammetry, geography and other related forms of spatial mapping.

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.

Below is the collection of common geomatics acronyms and abbreviations that you may find in the Canadian Geomatics industry (GIS, GPS, remote sensing, cartography, geography, surveying, Government etc.). If anybody knows of any key ones that missing off of this little Geomatics Acronyms and Abbreviations cheat-sheet then let us know and we will gladly add them to the list.

[page updated May 2016 – The list is now over 300, thanks to many people who continue to send us more Geomatics Acronyms and Abbreviations not on the list.]

Advancing Geographic Information Science

Advancing Geographic Information Science: the past and next twenty years

Advancing Geographic Information Science: the past and next twenty yearsLast summer (2015) marked the 25th anniversary of first International Early Career Scholars Summer Institute in Geographic Information. In celebration of the success of those institutes, scholars were invited to submit papers that would become part of a new 30 chapter digital e-book published by the GSDI Association Press.

Advancing Geographic Information Science, edited by H. Onsrud and W. Kuhn is the result of several invited and solicited submissions on Advancing Geographic Information Science. The main theme ‘Past and Next Twenty Years’ was chosen to help review the research challenges experienced over the past twenty years while discussing  some of challenges that will emerge during the next twenty.

Some of the technical influences on GIScience described in the book include databases, open source software, spatial data, GPS, web mapping services, mobile computing, crowdsourced data, and many other GIS related topics.

If you are concerned about data and many of the other issues surrounding GIS in the geospatial community, including ‘where the field has been‘ and ‘where the field is headed‘, then downloading and reading this book will be well worth your time. It can be ordered in print or downloaded digitally for free

GIS Conference and Events in Canada

GIS Conferences and Events in Canada

[page last updated March 2016]

Attending professional GIS conferences or  geomatics related events is always a great way to stay current with what is happening in the geomatics industry and provides amble opportunity to enjoy a good time while networking and mingling with others in the geomatics sector. GIS conferences or geomatics related events - 2005 CIG Conference in Ottawa

Many professional organizations across Canada offer great geomatics related conferences and events every year, so we created the Canadian GIS Conference and Events section on CanadianGIS.com as a way to provide the geospatial community with free information about the various related conferences, events, workshops, training seminars and webinars that are being offered.

Our events section includes a variety events related to GIS, remote sensing, surveying, cartography, geography and all other geomatics disciplines (and from British Columbia to Newfoundland).

We are fortunate enough to be able to attend several GIS conference and events every year all across Canada so we also post summaries of past events (when we can) with photos for those that were not fortunate enough to attend but wanted to know how the conference or event turned out.

Listed below are some of the upcoming GIS conferences, events and webinars.  If you know of one that is not listed in our events section or are planning a geomatics related conference or event and would like to have it listed for free  and promoted out through the Canadian GIS & Geomatics networks then let us know.
