Get started with QGIS	Vector data use X and Y coordinates to define the loctions of points, lines, and areas (polygons) that correspond to map features. To map a delimited file, the file need to have geospatial information (e.g. X Y Coordinates). X Y Coordinates are longtitude and latutide in degrees. WGS 84 is the most often used geodetic datum to represent coordinates A variety of basemap can be added to QGIS through adding an XYZ Tile layer.
Spatial Analysis in QGIS	Projection is the way to convert locations in a global onto to a flat plane. Choosing a right projection for a study area is crucial before any spatial analysis. The radius of created buffers is measured by Eucilidean distance.
Change layer properties	Make the point hollow to show overlapped points. Use contrasting colors to highlight the points against the basemap.
Creat print layout and Save the project	The basie elements for a maps are scale, legend, north arrow, title, and the content. You can save the map in three types: pdf, image, and SVG.
