Method & Code

Below is a description of our method and some code chunks that we used to produce the habitat prediction model maps.

Upload 2021 Census Data "American Indian/Alaska Native/Native Hawaiian"

We used the 2021 AIANNH Census Data specifically to look at the boundaries of Indigenous Land in the US. However, the goal was to identify the boundaries for the Yankton Sioux Tribe.

Subset the Data: Yankton Sioux Tribe

Now, we are speciically looking at the Yankton Sioux Tribe boundary data.

Plot Boundary and Reproject the Coordinate Reference System (CRS)

We want to plot the boundary data so we can see what it looks like. Next, we want to change the CRS to 26914. CRS is used to describe geographic data in Geographic Information System (GIS). The number 26914 refers to a specific CRS which covers the central part of North America from Canada to Texas.

Add Digital Elevation Model (DEM)

Now, we are going to add the DEM to the boundary.
