PHOTO GEOTAG TOOLS Toolbox (ArcGIS)
PHOTO GEOTAG TOOLS Tools is a collection of tools for processing and clustering photo metadata to generate Tag Maps and similar Visualizations:
Tagrunner All/Standard: This tool will cluster photo locations, calculate statistics (photos/ user numbers per cluster) and generate Alpha Shapes for the placement of labels.
Cluster Photo Locations: This Tool will cluster large point datasets and calculate basic statistics. Output is a point shapefile. This is an example of different photo locations clustered at Toronto High Park:
Calculate Weights: This is a Python based Model Builder script that runs a Weighting Algorithm to calculate a) a weighted number between photo count/ user count and b) to calculate the single densest cluster per tag ('HImP'). The following weighting formulas have been tested:
1+ [Join_Count] *(sqr(1/( [Join_Count] / [COUNT_User] )^3))→ Standard weighting formula
1+ [Join_Count] *(sqr(1/( [Join_Count] / [COUNT_User] )^2))→ less importance on User_Count in comparison to photo count
sqr(([Join_Count]+(2*sqr([Join_Count])))*2)→ Ignores User_Count, this will emphasize individual and very active users
This tool has been successfully tested in ArcMap 10.4.
