Panchromatic Airphoto Interpretation:
Panchromatic aerial images were acquired over the city of St. Catharines and Niagara-on-the-Lake (Queenston) and their surrounding areas. The images were interpreted using the seven elements of visual image interpretation (tone, shape, size, pattern, textture, shadow, and association) in order to identify fifteen different types of features (divided into two sections). By discerning different types of features in a panchromatic aerial photo, one is able to gain basic practical familiarity with analog aerial photography as well as basic practical familiarity with panchromatic images. Lastly, because black and white photos are a good introductory material for individuals who have never practiced image interpretation before, the images provided were a good source as there are numerous different types of features that can be identified within a city.
Stereoscope Usage, Elevation Estimates and Photogrammetry:
The purpose of the following assignment is aimed to serve as an introduction to the use of stereoscopic aerial photographs (stereo pairs) and basic photogrammetric calculations. By performing the approximate stereopair viewing method, the exact stereopair viewing method, and using introductory photogrammetric calculations, the assignment asked a variety of questions in order to help gain knowledge and insights on how to interpret and work with stereoscopes and stereoscopic aerial photographs.
This project was completed in partnership with Jordan Hamilton.
Georeferencing of Scanned Aerial Imagery and Change Detection:
The purpose of the following assignment served as a means to introduce the exploration and design of geodatabases in the form of both design and creation through theory based learning as well as practicality through geodatabase design based on scenarios. The knowledge gained from the assignment included, learning about multiple aspects about the three different types of geodatabases and the components of a geodatabase. It also taught how to choose the most appropriate geodatabase based on certain situations. Lastly, the ability to work with geodatabases using ESRI’s ArcGIS: ArcMap and ArcCatalog software. By designing geodatabases that include feature classes, domains, and subtypes, and integrity rules to point and linear feature classes, the goal of learning how to think through geodatabase design, data integrity, behaviour, and accuracy was achieved.
