Watch the Intro into the Arcmap Add-In to see an introduction to the various GBDX capabilities exposed in Arcmap.

If there is a specific text query, enter it into the query box. If no specific query is desired, leave the query box blank. Note: Entering a query will refine the returned results, but all further steps remain the same whether a specific query has been entered or not.
Vector Services AOI will be outlined in Green. As soon as the AOI is drawn, a query is sent and the vector sources within the AOI are returned.
Once a vector type is toggled, a percentage will display by selected vectors, informing the user of the stage of the loading process – only vectors that have 100% complete loading process will be added to the Table of Contents and to the map.
If the user wants to choose a different AOI, simply click Select Area again and the Vector Services tab will be cleaned. Draw the next AOI to issue the query for sources available under the new AOI. Note: All layers within the Table of Contents will remain when new AOI is generated or when the Vector Services window is closed.
See GBDX Catalog in Arcmap to view the step-by-step for GBDX Catalog in Arcmap.
Once ready click the Select Area button.
Note: Filters can be applied before or after the AOI is drawn. If filters are applied after the AOI is drawn the results in the table will automatically update.
Catalog AOI will be outlined in Green. As soon as the AOI is drawn, a query is sent and the catalog items within the AOI are returned.
Note: Table fields can be sorted by clicking field name.
In addition, you can view the footprint of each entry by hovering over the corresponding entry or toggling the desired entries.
A dialog will prompt you to save table entries to a CSV file.

If a specific date range is required toggle Specify Date Range and select desired dates, or if a query is required add it to the Add a Query Filter.
After the AOI is drawn and filters/parameters are selected click Go. A polygon layer with a populated attribute table will be added to the table of contents after processing is finished.
This tool calculates the change between two aggregations over the same area that represents different time slices. Geohash size must be consistent in order to obtain valid results from this algorithm. The algorithm performs a sparse cosine similarity based on all field values for each row, and calculates the difference between all fields individually. The output feature class will have the union of fields from both input features. Any pivot table will work.
Step 2: Click Refresh drop down lists then select the two desired aggregation layers from each drop down list.
This tool shows a similarity heatmap based on a selection. Similar in nature to a "more like this" function. If many cells are selected then there will either be an output layer for each selected cell, or the average will be calculated. If an average is selected, then a graph of similarities between each feature will be printed out.
Step 2: Click Refresh drop down lists then select the desired aggregation layer that contains the selection from the drop down list.
Step 3: Make a geohash selection with the ArcMap Select Features tool or from the attribute table on the selected aggregation layer.
