More effective way to display map

Hi all,

I generated few outputs from the Nutrient Delivery Model (i.e. p_export.tiff). What would be the best way to create a nice map for a poster presentation. The file is a tiff file but it is not recognized as a raster when I try to convert it to a polygon file. I am new to the forum so I apologize if I am posting this question under the wrong topic.

Thanks for any suggestions you will have!

Welcome, Laura,

In general, you should be able to use QGIS, ArcGIS, or even a graphics program to display a tiff file and select a color map for it. You need not convert it to a polygon in order to display it.

If the software you are using is giving you a specific error or problem, then you might have a general GIS question better suited for google or

Good luck!
