So you want to make a Map: Where and How to find Data (QGIS)

Before you get started with GIS, you need data. This session shows you how geospatial data is made and collected, the types of formats that can be brought into QGIS, and a variety of local data sources. The version of QGIS that is used in this video is 3.40.11. To help access the data used in the exercise, here are the links: • Sampling Data - https://ed.marine-geo.canada.ca/index... • Coastline Data - https://natural-resources.canada.ca/s... • Elevation/Bathymetry Data - http://www.ngdc.noaa.gov/mgg/image/2m... 0:00:00 Introduction/Start 0:02:22 What is Geospatial Data? 0:04:00 How is Geospatial Data Collected? 0:10:04 Types of GIS Data 0:13:01 File Formats 0:14:08 Vector Formats 0:14:47 Raster Formats 0:15:20 Coordinate Systems 0:17:52 Datums 0:20:20 Scale Issues 0:20:56 Data available at the GIS Centre 0:22:27 Free Data Sources 0:25:52 Running Scenario 0:26:32 Accessing and bringing in ASCII data to QGIS 0:43:54 Evaluating ASCII data brought in (there are issues!) 0:46:35 Changing symbology of points 0:49:18 Accessing and loading vector line data (coastline) 0:55:49 Accessing and loading raster data (elevation and bathymetry) 1:02:01 Changing layer order to improve visibility 1:03:43 Changing raster layer colours 1:09:23 Saving QGIS Project 1:12:04 A few more tips 1:13:46 Contact information
