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.
Decimal degrees (DD) is a way of expressing latitude and longitude geographic coordinates as decimal fractions (e.g 54.135°) and an alternative to the more common format of Degrees, Minutes, and Seconds (DMS). But there are many times when you are supplied with latitude and longitude coordinates in decimal degrees but you need them to be in Degrees, Minutes, and Seconds. There are several easy solutions that you can use, but I prefer to use this converter that I created in Excel.
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 …
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
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.
“My career and has allowed me to be involved in many projects that go well beyond what my education prepared me for.”
When I started off my geomatics career I thought it was better to become specialized in a particular trait and that would maintain my career path. Well that did work out pretty good for a few years, and I became very efficient in one aspect of geomatics (orthophotography and imagery analysis). However one day I realized that I was focused only a narrow spectrum of the skills that I had worked so hard to learn. As a result I was losing many other skill-sets that I had developed.
Since then I have almost gone to the other extreme and have become diversified, experienced and well rounded with a multitude of geomatics skills which has in turn often provided me an edge in my career and has allowed me to be involved in many projects that go well beyond what my COGS education prepared me for. And I find that it makes for a more interesting career when your job allows you to combine a multitude of different geomatics aspects together.
