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…
Accessing the GIS Lab The GIS Lab is available 24/7 to students enrolled in a GIS class; while the lab is not being used for other classes (see the home page https://gis.unbc.ca/ for the schedule), you may use the lab while other classes are ongoing so long as all students Read more…
In the Lab: BC TRIM NOTE: The BC TRIM dataset is very large, attempting to load certian layers for the whole province may take an excessive amount of time. Please zoom in on your area of interest before loading the layer. After you have loaded a layer for your area Read more…
Introduction Today we will be making maps that can be published on the internet (and actually publishing them!) The process of publishing the map is actually quite straight forwards, however, the cartographic principles we use do change somewhat. Up to this point, we have had a great deal of control Read more…
1. Examining Satellite Images In this section, you will be working with Sentinel-2 satellite imagery, where most images you see contain Blue, Green and Red (more commonly known as RGB) the Sentinel-2 images contain 13 bands. The full list of bands is available from the European Space Agency: https://sentinel.esa.int/web/sentinel/user-guides/sentinel-2-msi/resolutions/radiometric There Read more…
