activity : nca4-tribal_lands_northerngreatplains_v2-process



Modified the “Tribes NCA-NGP Region” to add appropriate Tribal Code used in the Tribal Trust Lands shape file layer.

Joined the Tribal Trust Lands shape file layer to the Tribes NCA-NGP Region table in ESRI ArcMap based on the Tribal Codes fields of each.

In ESRI ArcMap, color symbolized the above Joined Tribal Trust layer based on Reservation name with unique foreground color for each. Downloaded and added to ArcMap view the Tribal Lands layer from national map website: Color symbolized the Tribal Lands Layer so that it matches same color symbols for reservation name as Tribal Trust Layer. Added State and North Central Climate Sci Cntr (NCCSC) boundary and clipped all above tribal lands to NCCSC boundary. Save the map view as TIFF image in ArcMap.
