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.

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 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.

Converting between UTM, MTM and LAT/LONG

I am sure that most of us have run into times when we have features that have defined coordinates of one system that we need to use with a different one. (E.g. your map is in UTM (Universal Transverse Mercator) but you have been given GPS points in Lat/Long).

If you ever find yourself in need of quickly getting values converted from Geographic to UTM / MTM (Modified Traverse Mercator) or UTM / MTM to Geographic then here is a a free online geographic coordinate convertor tool that I often use provided by Canadian Spatial Reference System

Google Earth Time Zone Clock

Time Zones in Google Earth

Every now and then I come across some little utilities that help to make things easier while working in the field and these pages are mainly my way of sharing them with others while creating a go-to place where I can easily find them when I need them.

Here is a neat little Google Earth file that has often been helpful on many of my field trips when trying to remember where time zones start and stop. Just open the file in Google Earth, then point and click your location to get info on that time zone.

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.
