Prince Edward Island Aerial Photograph Archives
The province of Prince Edward Island has always been pretty good and open about making their PEI aerial photography available. They have an in house library in Charlottetown where prints and copies can be ordered as well as an online interactive web map service allowing users to search and download lower resolution versions of their aerial photography.
The online initiative began shortly after the 2000/02 Corporate Land Use Inventory Project had completed. This extensive project involved creating orthophoto maps from over 16 thousand 1:17.5k false color infrared images. The orthophotos were then tiled to match the provinces topographic map series and all land use of the island was updated using air photo interpretation and heads up digitizing.
The project was a large success and stirred fond interest from other government departments and the public leading to the scanning of historic photos from the provinces air photo library. An online map interface was then developed to help make it easier for users to search photos and the ability to download images was included for easier access. Electronic versions of the images on CD-ROM are available from the PEI Resource Inventory and Modeling section in Charlottetown (e.g. 34 CDs provide full coverage of the Province in the 2000 series).
Selecting a different air photo series of the left will change the points on the map to represent the flight lines of aerial surveys for that particular year. This tool is great for projects that involve historic work in the same area.
PEI Aerial Photograph Interactive Map Tool
The PEI online map application displays the collection of aerial photos that are available from a set as points on the interactive map. Then users can view a thumb-nail of any photo simply by double clicking on one of the map points. Larger version of the file can then be downloaded, images are in JPEG format (reduced in size by 25% from the in house scans), with download file sizes ranging from 2 to up to 10 mb.
Aerial photographs of Prince Edward Island are available for download from surveys of 1935, 1958, 1974 and 1990, 2000 & 2010. The type of imagery available depends on the aerial photo survey of that particular year, thus you will find that there are colour images, false colour infrared and black and white images.
The department has also gone ahead and generated some quick-search pages allowing users to browse Aerial Photographs by community if they do not wish to use the interactive map tool. So users can pick a community from the provided preset short-cut list to see a list of photographs available in that area.
For example you can click on Charlottetown and it will open up a page containing thumb nails with relevant photos for the Charlottetown area with links to download the corresponding image or open it up larger into your browser.
There is also a set of images on their interactive map tool of oblique aerial images of select places across the island that can be viewed similar to the way the traditional air photos are with the map tool.
The province of Prince Edward Island continues to do a great job at making their aerial photography available to the public and this interactive map tool is your key to finding aerial photography for anywhere in Prince Edward island that you can then use with ArcMap, MapInfo, Google Earth or any other GIS based software as well as other non GIS uses.
