I want to plot a heat map which shows the different usage in different areas. But the thing is, in my original dataset, the data got truncated, which means that each point represents a small area rather than a certain point of latitude and longitude. For example,
(14.21, 55.38)-> represents a square of place for (14.21XXXXXX,55.38XXXXXX)
I have searched the tutorial file and tried, but I can only get my points with different shapes and darkness, rather than making them continuously showed in a map. I am new to GIS and MapInfo.
Can you give me some ideas of how to transfer my points to grids, or how to directly use the points to create heatmap which is not displayed discretely?
