Renewable Resources Resource Management Part-time Studies Course

School of Construction and the Environment

To support you and your education, BCIT is adapting applied learning in formats appropriate to the unfolding global situation. Spring and Summer PTS classes are being delivered in an online format unless you are notified otherwise.

Course Details

Introduces various mapping systems (such as the NTS and BCGS) that are used in the resource industry, as well as the coordinate systems (Lat/Long, UTM) that are commonly referenced. Other topics include the calculation of map and photo scales, indexing, radial line plotting and basic interpretation of aerial photography.



This course was retired after the Fall 2007 term and is no longer offered through BCIT Part-time Studies.

Learning Outcomes

Upon successful completion, the student will be able to:

  • Describe uses, features and characteristics of a map.
    • Describe how TRIM series and MOF maps are used in resource management.
    • List the typical components of a map and the reason for each.
    • Use common mapping symbols for creating simple maps.
    • Triangulate or locate a position on a map given three compass bearings.
    • Provide a lat./long. or UTM coordinate of a position on a map sheet.
    • Be familiar with the NTS and BCGS system of indexing map sheets.
  • Use scales to determine distances on a map or estimate distances on an aerial photo.
    • Describe the types of scale on a map and the advantages of each.
    • Use a triangular scale to measure distances on a map.
    • Produce a hand drawn map to scale showing features common in a forested area.
  • Describe the characteristics, uses and features of aerial photos.
    • Describe how aerial photos are created in order to allow for stereo viewing.
    • List advantages of aerial photos over maps.
    • Use three different methods to calculate estimated scale of an aerial photo.
    • Describe the differences between a map and an aerial photo and describe how these differences affect the use of each.
    • Define displacement and describe how displacement affects the use of aerial photos.
    • Determine the direction of North on an aerial photo.
    • Use an air photo index to determine the photos required to cover a specific area on the ground.
    • View stereo pairs of photos in three dimensions.
  • Estimate the size of areas on a map or aerial photo.
    • Use a dot grid to estimate areas on maps and photos.
    • Describe at least two other methods for estimating areas.
    • Describe limitations of area calculations from aerial photos.
  • Use a topographic map for determining slope and stream flow direction.
    • Interpret the boundaries of a watershed on a contour map.
    • Determine slope and aspect of specific locations on a contour map.
    • Project a road of specific grade onto a contour map.
  • Describe the advantages and disadvantages of ortho photos.
    • Describe in general terms how an ortho photo is created.
  • Use aerial photos to navigate in the woods.
    • Use images on an aerial photo to find features on the ground.
    • Estimate distances and bearings to find locations on aerial photos.
  • Timber type using aerial photos.
    • Describe and identify the aerial photo characteristics used in timber typing and the delineation of polygons.
