Categories, Sub-Types and Properties of Spatial Data - ARCHIVED

This tutorial covers the main categories and sub-types of spatial data used in GIS, as well as three properties that make datasets spatial: map projections, datums and coordinate reference systems. We’ll also discuss the distinguishing characteristics and applications of vector and raster data, as well as their associated sub-types (vector: points, lines and polygons, raster: singleband, composite and thematic) and common file formats. This understanding will provide the necessary skills to navigate online geospatial archives, such as Canada’s Open Maps, and download relevant datasets in the optimal format for your intended use – which we’ll cover in Part II of this tutorial.
