How to plot a geographical surface temperature heat map?
34 ビュー (過去 30 日間)
I have this Temp_Data.mat file (attached) that contains Latitude (917x345), Longitude (917x345), and sea surface temperature (917x345) matrices. Everything is very straightforward. I want to plot the surface heat map.
But the problem is the Latitude and Longitude range is very small for this problem. It only covers 41.25°N to 41.75°N and -71.45°W to -71.20°W. So, I am facing problem plotting this heat map. Specially, the coastal boundaries are very bad when I use the geoshow or geoplot function.
I just want to know if it is possible to plot for such a small spatial domain in MATLAB. Please let me know. Any feedback from your side will be highly appreciated.

Hi Ashfaq, as per my understanding, you have three matrices namely Lat, Lon and Temp, and you want to create a heatmap from them. Since the range of longitudes and latitudes is small, you want some method that creates plot with narrower lat. and long. limits on the axes. For achieving that, you can try using the geolimits method like this:
geolimits([41.25 41.75], [-71.45 -71.20])
