Spatial Data Diagnosis: Creating Heat Maps for Broken Data Sources


Blog series on reviewing spatial data and identifying broken files and issues, including creating heat maps for broken data sources.

Here we are. Another #MarcoMonday, another route on our Q+A quest. Piggy backing on last week’s journey to finding those users responsible for the most broken ArcGIS Map Documents and Layer Files, let’s delve more into those datasets associated with broken ArcGIS Map Documents. For instance…


What are the most commonly referenced datasets in broken map documents?

To better answer this, we will need a lot of help from our friend Integrated Marco Desktop and maybe a little nudge from Integrated Marco Commander.

Although all inventory-friendly applications within Integrated Marco Studio make it possible to determine this type of information, Integrated Marco Desktop is one of our favorites for finding this information quickly. Within this Add-In to ArcGIS Desktop, there lives a hot method for determining dataset and ArcGIS Map Document brokenness relationships – Heat Mapping.


Heat map in Excel of broken ArcGIS Map Documents (.mxd), spatial data files, shapefiles, geodatabases, feature classes, etc.

With the help of the Heat Map from Inventory Log tool, you may create a heat map diagram based on the output generated by the Data Inventory Logger tool. The output shows the path to each dataset (both full and short), whether it is broken, and which Map Document or Layer File in which it is used. Those colors associated with each swatch help you to quickly identify their status as well, with orange tones associated with broken data and blues with working connections.
