Digital Geoscience Maps Tutorial: Finding a map
Let's suppose we want to solve the following problem. We wish to
find units in a bedrock map around Frobisher Bay.
We want to look for bedrock maps, so be sure the radio button next to
"Index - Bedrock Geology Maps" is selected, to make that layer active.
To find the map, we can either find it:
- spatially by zooming and panning to the location, then using the Select Tool,
![select select](/web/20061102135920im_/http://gdr.nrcan.gc.ca/digmap/images/select_rect_1.gif) - or we can use the Find Tool,
, to search for the map.
Let's try both ways:
- Spatially
- First we will zoom in to the southern tip of Baffin Island. Click the
button, then use the mouse to draw a rectangle around the maps there.
- Click the Selection Tool,
, then click within one of the orange rectangles. When you find one with title "Frobisher Bay", you're done!
- We can now display this map (see below).
If it isn't on-screen, you may have to click the Pan Tool, ,
and drag the map around until you see it, or use the four blue arrows to
pan in each cardinal direction. (Hint: Frobisher Bay is very close to Iqaluit).
Once you find the map that contains Iqaluit, use the Select Tool,
, to display
the attributes of the map. Notice that the title is "Frobisher Bay" and
that this is an A Series map with series number "1979".
- Now let's try finding the same map with the Find Tool:
- Press your browser reload button to restart the application.
- Now click the
button to activate the Find Tool.
- Select the field "Title" for the search. Type "Frobisher" in the input field, then press the "Find String" button.
- One record is found. Click the
to automatically zoom to the map. We note that the title is "Frobisher Bay"
and that this is an A Series map with series number "1979". We have found
the map we are looking for.
Displaying the map and getting more information |
Now that we found the map, we want to see this map. With the search
results still in the Text Display Area, you can use
the button to add the selected map to your selected layers in the legend
and to automatically display it. You can use the button
to display the
map's legend and interact with it. Also, by clicking on the layer title,
you will get metadata about that map.
