Geomatics Acronyms and Abbreviations

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.

Geographic Information Systems (GIS)

GIS have become a rapidly growing field that allows people to solve & model real world situations by incorporating spatial and tabular data. GIS operates on many levels and has become an essential tool for most urban and resource planning and management organizations. In this section I include helpful online resources, information about  GIS, and various samples (I also have another website fully dedicated to GIS: CanadianGIS.com).

Cartography / Map Design

Custom graphic map of Pictou County, Nova Scotia

The practice of creating maps or visual representations of a surface from above it is known as Cartography. Traditionally maps have always on paper, but since the introduction & wide spread use of GIS, cartography has evolved more into digital formats. In the cartographic section I include helpful online resources, information about cartography and samples maps.

Geomatics – GIS data base modeling

Spatial Database Modeling of forest stands in Kejimkujik National Park

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.

Geomatics – GIS Spatial Modeling

GIS Model of Average Annual Precipitation of the Annapolis Valley, Nova Scotia

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. There are four traditional types: spatial overlay surface analysis, linear analysis, and raster analysis.

Here, ESRI Geostatistical Analyst was used to create a model that can be easily used to depict the amount of precipitation that a community in the region would experience based on the data from the databases.

CanadianGIS

CanadianGIS.com is an extension of my web site that I started back in 2006 after I noticed that there was a real need to have one good place on the web to help find Canadian GIS resources. The site helps provide others with resources about Canadian GIS data, basic information about Canadian companies that provide GIS services, locations of Canadian data and maps, information about GIS events, places to find Canadian GIS employment and education info and many other great resources.

Digital Elevation Models (DEMS)

Digital elevation model (DEM) of Lismore, Nova Scotia

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
