Cartography

Converting between UTM, MTM and LAT/LONG

Canadian using a UTM map

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

UTM Zones in Google Earth

UTM 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 I needed to know what UTM zone I was working in. Just open the file in Google Earth, then point and click your location to get info on that time zone.

Geomatics – Cartography

Cartography or Map Design 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) and computers, cartography practices have evolved more into the digital world. Most maps today are now generated using map software that falls into one of three main types; GIS, CAD, and specialized map graphic design software.

Kejimkujik National Park and Historic Site ortho photos

Below is a poster created showing a seamless ortho photo mosaic of Jeremys Bay Campground, Kejimkujik National Park and Historic Site created from several 25 cm resolution aerial photos flown while studying at COGS in 2003. The image has the location of campsites layered on top and was created for a Spatial GIS Vegetation Database and GIS Spatial Modeling project that I worked on during the summer of 2004.
