Oct 10 quiz review Flashcards
Google Earth is a free and common internet-based mapping program that can be used to search for locations on the earth by place, name, or ?. The satellite imagery for these locations can then be viewed from multiple angles and perspectives (3D), along with other mapping layers for that area (roads, facilities etc).
Further, there are tools in Google Earth for displaying GPS and ? datasets, and sharing these customized maps with others. (The Imagery for Google Earth is constantly being updated from various sources and is of varying quality.)

ACTIVITY: Folder Organization
It is always a good idea to organize the information you collect as a result of field activities you perform. It can cost your company ? and ?
…AND your own reputation is on the line if you are unable to retrieve information in a fast and efficient manner.

Search for Place Name Locations in Google Earth
It can be a good idea to learn something ? of time about the various places you visit in your work life – prior to actually leaving on your trip. This can help avoid frustrating delays in ? or worse, not finding your field sites at all!

(Notice the different types of place names that can be entered – City Names, Park Names, River Names etc etc .)
ACTIVITY: Google Earth Setup
To change the units that the coordinates are displayed in, and the units of elevation, make the following change to your Google Earth Setup now.
? Menu > Options
Show Lat/Long as Decimal Degrees
Show Elevation as Meters, Kilometers

Google Earth – Navigating
Google Earth Help > User Guide > Navigating in Google Earth
Left mouse button, press and drag to pan.
Roll the wheel to ?. Press the ? and drag to tilt and rotate.
You can also use the Navigation joystick controls at the upper right part of the display.
To reset the display: n > north at the top; u > reset tilt to top-down (up);
r > reset both north & tilt.
And there are many other ways to manipulate and navigate the display.

Google Earth – Measuring
You can measure the distances between objects that are visible in the google earth imagery.
Goto the “Tools” Menu > ?
You can use the Ruler to measure along a simple 2-point line (includes heading info), or you can use the “Path” option for more complicated measuring lines that are more than 2 points or clicks of the mouse.
There are several options for setting the ? ? (m, ft etc).

Save an Image for each site
Once you have located both of your sites in google earth, you will proceed to save an image of each location to a separate .jpg file.
Before you save an image for each site, please zoom out so that the entire section of land with the surrounding range/township roads are visible. (1 section = )
Goto File Menu > Save > Save Image
1 mile by 1 mile
Finally, Print the Map to PDF File Menu > Print
Map Options button > Turn on Title and Description, Legend, ? and ? options. Add a title and description to the map.
Select the Print button in the toolbar.

Convert Geographic Coordinates to Legal Land Locations
Not everyone understands geographic coordinates as well as you do (). In order to facilitate additional communication about land locations, it can be important to describe places using multiple land references – in order to reach all the intended target audiences at the office or in the field.
A converter program is available from the ? Website that will convert geographic coordinates to the ??? (legal land) location format. (and vice versa)
The online coordinate conversion program can be found at the following website:
Alberta Energy Regulator (AER)
Alberta Township system
http://www1.aer.ca/GISConversionTools/conversion_tools.html
Pick the last tool: Convert latitude/longitude to Alberta Township System (ATS)
Enter the geographic coordinates for both site locations shown in Google Earth (your placemarks) in either decimal degree form (first field only) or in degrees, minutes, seconds format. (don’t confuse Lat/Long info!)
