Agisoft Metashape Pro Software We are going to be using software specifically written to produce three dimensional modelscreated from overlapping photos taken from any type of imaging equipment. This is a Russiancompany called Agisoft called Metashape Pro. Over the years Scott has had several projects thatmake use of Metashape Pro Read more…
For today’s lab, we will be looking at image segmentation using SciKit-Image, while there are other software platforms that we could use SciKit-Image is used as it offers a large selection of algorithms and provides a good framework for testing hyperparameters (hyperparameters are the variables used to control machine learning Read more…

Today we will be leveraging the cloud, the short version is that the cloud is any service that uses IT resources accessed through the internet and not on the campus we are currently at. For remote sensing this is particularly advantageous as we can access data without the restrictions of Read more…
Today we will be processing some Radar data using a program called SNAP, an OpenSource application released by the European Space Agency for processing Sentinel data, and can perform most of the remote sensing tasks we have done to date. Start by opening snap and we will take a look Read more…
Introduction In today’s lab, we will be doing our work inside a web browser (if you are connecting from home you will still need the VPN); using a website https://jupyter.gis.unbc.ca. This is the first of several labs this semester where we will be working primarily with code as opposed to Read more…
Sentinel Data Download We will start the lab today by downloading some data you will need for this week’s assignment; once we start the download, we will move on to the rest of the lab while it downloads. Sentinel data can be downloaded from the European Space Agency Data Hub:https://scihub.copernicus.eu/dhus/#/home Read more…
