Splitting data so that two maps can be made

[DanielBon]

Hi I'm new to using ArcPro, and I need help splitting data.  I have wildfire data that has years from 1878-2019 and I would like to split it to show two sperate maps. The maps would show years from 1879-1948 and then 1949-2019 to show changes in wildfire activity. I just need an explanation on how to split the data. I know the basics of how to insert the data, the attribute table and map making. It's just splitting the data is what is causing trouble.  I uploaded the file below for an example

Thanks!

This sounds like a job for definition queries! I haven't seen your data (you provided a project file, but that doesn't include the data. You might try saving it as a map package, which does include data), but I assume it's all in one layer / feature class. If there are attribute(s) allowing you to separate based on years, you can use the same source for more than one layer, each with a definition query to show the particular years of interest.

I'm honestly still having trouble as the definition query is not showing. Ill share the dataset below. I appreciate the quick response! I cannot share the dataset as it says it does not support the .tif file. Ill share the webpage below that has the data set. I'm just using the "Contiguous_US_First_Year_Burned" data

Ah, that might be the problem - you can't query raster data, only vector data. TIF is raster, just like JPG, PNG, GIF, etc. It looks like that page offers a few different options; make sure you use "Wildfires_1878_2019_Polygon_Data.zip". Polygon means vector. Vector means discrete features that can be queried. 

You're welcome for the quick response! Welcome to the community.
