GIS OU Hierarchy Guide

Annie Yu -


The DATIM GIS OU Hierarchy Guide below provides a reference for the prioritization, community, and facility level definitions for each OU as displayed in DATIM with information on whether it's possible to map that level in the DATIM GIS Module. The reference also provides the common name for these levels (e.g. municipality or parish). Finally, the guide shows the level of the facility along with the percent of facilities that currently have associated latitude and longitude.

This guide is oriented for use with the GIS Module and identifies the appropriate level to select in the drop-down menu if you want to map at the prioritization level, community level or facility level. If mapping is not currently supported at one of those levels, please select the next available level up and the GIS module will aggregate results to that higher level. *IMPORTANT NOTE: mapping at a level higher than a variable was collected or calculated on is currently only advised for count variables, NOT percentages because the GIS module aggregates by summing values.*
