Paper Collection

The paper collection is a non-circulating research collection of sheet maps, globes, air photos, microforms, digital atlases and cartographic reference works. 

Each semester, we compile a list of newly acquired maps and atlases [1]. As of March 31, 2011 the cartographic collection comprised almost 200,000 items including:

  • Sheet Maps: [2]Over 170,000 sheet maps which are broken into 2 categories: thematic & topographic.
  • Atlases: [3] Over 4,000 atlases on a variety of topics and locations.
  • Air Photos: [4] Over 11,000 paper air photos focusing on Ottawa and the surrounding area, including the Ottawa Valley and the Gatineau region.
  • Wall Maps: Over 300 wall maps that can be borrowed from the MADGIC reference desk for classroom use.
  • Globes/3D Objects: 31 globes/3D objects are available and can be borrowed from the MADGIC reference desk.

Air Photos

Our print air photo collections are self-serve and available during library opening hours.  The photos are for in-library use only.

Main Collection

Our main collection contains over 11,000 print air photos focusing on Ottawa and the surrounding area, including the Ottawa Valley and the Gatineau region.  Air photos in this collection are in black/white or colour depending on the series. 

Find air photos from this collection using our online index [5].

To locate an air photo in the library, first search for it in our catalogue using a keyword search [6] for "aerial photograph".  Air photos are filed in their boxes numerically by flight line, then photo number.

Northern Communities Collection

This sub-collection of air photos covers selected communities and natural features in Nunavut, the Northwest Territories and northern Quebec.

Photos from this collection are not included in the online index.  Ask at the Maps, Data, and Government Information Centre [7] for assistance.

Nunavut

Limited coverage of Frobisher Bay, Gjoa Haven, Hall Beach, Hall Lake, Igloolik, and Lake Harbour. Individual photos can be in editions dated from 1968 - 1976. Various scales.

Northwest Territories

Selected populated areas such as Fort Resolution, Fort Simpson, Hay River, Inuvik, etc. and natural features such as the Mackenzie Delta, etc. Individual photos can be in editions dated from 1968 – 1976. Various scales.

Northern Quebec

Some populated areas such as Fort George, Poste-de-la-Baleine, etc and some natural features such as Grande Riviere de la Baleine, Hopes Advance Bay, etc. Individual photos can be in editions dated from 1968 - 1976. Various scales.

British Columbia

Only Hackett River.

Digital Air Photos and Orthophotos

Our collection of digital photos includes the City of Ottawa, sections of the National Capital area and selected other Canadian cities.  Consult our GIS pages [8] for descriptions of the photos and indexes.  This collection is only available to Carleton students, faculty and staff.

Air Photo FAQ

Can I photocopy an air photo?

Most of our air photos may not be photocopied unless permission is obtained from the copyright holder.  For more information on photocopying, please visit the MADGIC Reference Desk.

Can I use my digital camera to photograph an air photo?

Not without written permission from the copyright holder, unless the photo is more than 50 years old and therefore no longer subject to copyright law.

Where can I buy these air photos?

Copies of the 1:30,000-scale photos flown in 1987 and 1988 and the 1:10,000-scale photos flown in 1991 can be purchased from the Ontario Government at the Ministry of Natural Resources' Store. Copies all other photos can be purchased from the National Air Photo Library in Ottawa. These government agencies will also have many other photographs that Carleton University does not.

What is meant by the scale of the photograph?

Scale refers to the relationship of distance on photographs or maps to the actual ground distance. It is a ratio that could represent any unit of measurement. For example, a scale of 1:40,000 means 1 inch on the photograph equals 40,000 inches on the ground, or 1 centimeter equals 40,000 centimeters on the ground.

Why does scale matter?

Medium and small-scale (over 1:30,000) photos are used for general planning. Large-scale (1:30,000 and less) photos are used for detailed work, such as finding lot lines.

Do I get more detail with an enlargement of an air photo?

No. An enlargement only appears to show more detail than a 9-by-9 inch photograph. Photographic resolution deteriorates with each enlargement factor.

Why are most photographs acquired looking straight down from the aircraft?

Because most aircraft photography is used for cartographic purposes so the photographs acquired looking straight down or vertically will have the least distortion.

What is meant by resolution?

Resolution refers to the ability to distinguish the smallest visible objects on a photograph. Resolution is a result of the combination of film type and the camera lens system.

What is meant by flight line?

A flight line is a path on a map or chart to represent the track over which an aircraft has been flown or is to fly.

Sheet Maps and Atlases

Sheet Maps

Some of our maps can be found using the search box above, but many of them are not listed in our catalogue. They are organized using a numerical map classification system. Within this system, maps are separated into topographic or thematic.

Topographic

  • Show features of the earth’s surface.
  • Provide more detail; scales are 1:1,000,000 or larger.
  • Show contours or land elevations
  • Sheets are contiguous.
  • Issued by a national government agency.

Topographic maps are arranged by area classification [9] only, and have a call number ending in a 7.  Topographic series have indexes found in the first folder of each series.

Example: 1007 = Canadian topographic map

Thematic

  • Show a particular theme or subject: geology, population, tranportation, etc.
  • Can be produced at any scale.

Thematic maps are organized by area classification [9], and have a call number ending
