Published on

In this session, two ACEs passionate about advanced spatial analytics come together. Advanced spatial analytics is music to their ears, akin to hearing The Beatles for the first time. Listen in to see how two ACEs solve challenging spatial analytics problems to unlock key location intelligence insights using the Alteryx Platform. You won’t want to miss how John creates dynamic map atlases filled with hundreds of pages of insight. Plus, this session covers how Deanna leverages spatial and demographic datasets to perform site selections for hospital locations that reveal optimal new sites benefitting underserved populations. This dynamic duo welcomes your curiosity and questions, so bring your questions on how to integrate Alteryx into your current spatial analysis processes and learn from the best!

Across the Universe: Advanced Spatial Use Cases in Alteryx

  1. 1. # A L T E R Y X 1 9 PRESENTED BY ACROSS THE UNIVERSE: ADVANCED SPATIAL CONCEPTS IN ALTERYX John Hollingsworth JohnHollingsworth@clearchannel.com Deanna Sanchez DSanchez@teknionusa.com
  2. 2. # A L T E R Y X 1 9 COMPLETE SESSION SURVEYS ATTENTION 2 You were handed a survey as you entered the room. It should take less than 2 minutes to complete Please return your completed surveys B E F O R E YO U L E AV E the room Surveys are anonymous, and we rely on your opinion for improvement
  3. 3. # A L T E R Y X 1 9 3 With Alteryx, I can work at 10x speed with 10x visibility vs. competing tools. JOHN HOLLINGSWORTH When I use Alteryx, I feel so grateful. All other softwares are so cumbersome. A L T E R Y X U S E R S I N C E D a y 1 ( 1 / 3 1 / 2 0 0 6 )
  4. 4. # A L T E R Y X 1 9 4 With Alteryx, I can open a new world of spatial and demographic analytics, at speeds I only used to dream about. It allows me to consistently go above my current stage, always learning, growing and advancing to the next level. DEANNA SANCHEZ When I use Alteryx, I feel like a Unicorn! Unique, capable, and able to accomplish the impossible. A L T E R Y X U S E R S I N C E 2 0 0 5
  5. 5. # A L T E R Y X 1 9 5 TODAY’S AGENDA 1. Create and Use Fractal Grids 2. Group Grids Into Threshold Groups 3. Site Selection for Healthcare 4. Spatial Match Patients to Catchment Areas 5. Append Demographic Data 6. Find New Locations 7. Q&A
  6. 6. # A L T E R Y X 1 9 BUSINESS PROBLEM 6 - Create a printed street atlas for our coastal markets to be used in disaster response after a hurricane. - Trial and error determined that an appealing label output required a maximum of 50 labeled points in each map. - Using a uniform grid size to create pages resulted in some pages that had too many point labels or too many pages for the atlas to be useful. Too many points resulted in too many labels.
  7. 7. # A L T E R Y X 1 9 WHAT IS A GRID? 7 The Make Grid tool will take an input stream of spatial objects and a side length to create a field of square polygons to cover: a) the entire dataset or b) each individual polygon spatial object All of our inventory in Atlanta 10 mile grid based on those points Tool properties and icon
  8. 8. # A L T E R Y X 1 9 10 MILE GRIDS 8 Pros: Only 44 pages in the resulting atlas Cons: Some of the grids have hundreds of points to label in them
  9. 9. # A L T E R Y X 1 9 2 MILE GRIDS 9 Pros: Getting closer as only two grids have more than 50 points in them. Cons: Now there are 293 pages in our street atlas To get to less than 50 points in each grid, the grid size was 1.65 miles and resulted in 348 pages!
  10. 10. # A L T E R Y X 1 9 10 Fractals are a mathematical concept that essentially means to divide/continue/evolve a shape into smaller (and similar or identical) copies of itself. ‘Fractal Grids’ are square polygon objects that are dynamically sized based on how much stuff is inside them. If they contain more than the maximum number of objects, then they are split into four grids. Use them to divide and conquer. WHAT ARE THEY AND WHEN WOULD I USE THEM? FRACTAL GRIDS
  11. 11. # A L T E R Y X 1 9 DIVIDE GRID BY FOUR, COUNT POINTS WITHIN, FILTER, REPEAT 11 46 14 169 105 21 13 10 8 57 78 45 42 Repeat Until Done334
  12. 12. # A L T E R Y X 1 9 FRACTAL GRIDS 12 Starting size of 16 miles Pros: All 107 resulting grids have 50 or fewer points. Cons: None. Output meets criteria. But is there a way to even improve on this?
  13. 13. # A L T E R Y X 1 9 FRACTAL GRIDS 13 Size calculated based on Minimum Bounding Rectangle of the input data Set side length to zero in the macro input Now only 98 resulting pages!
  14. 14. # A L T E R Y X 1 9 BUSINESS PROBLEM 14 - Evenly allocate portions of the market for service technicians to visit - Try to assemble groups of points that add up to as close to 50 points as you can so that the work of visiting the sites can be evenly distributed among the technicians
  15. 15. # A L T E R Y X 1 9 GROUP GRIDS TO MEET THRESHOLD 15 Iterative macro groups nearby grids together to get as close to the threshold value as possible. 53 resulting groups
  16. 16. # A L T E R Y X 1 9 FREE MACROS! BOTH OF THE MACROS IN THE FOLLOWING DEMONSTRATION ARE AVAILABLE ON THE PUBLIC GALLERY 16

  18. 18. # A L T E R Y X 1 9 BUSINESS PROBLEM 18 • Analyzes drive time distances and spatially matches patients to their hospital catchment drivetime areas • Determines top Experian MOSAIC Segmentation for each hospital patient group • Finds block groups with similar demographics and calculates percentage of top segment • Spatially matches patients outside of catchments areas to target block groups • Generates maps of patients within existing catchment areas, and those in underserved areas • Visualizes target block groups containing patients where new hospital locations may be optimally sited SITE SELECTION FOR HEALTHCARE WORKFLOW
  19. 19. # A L T E R Y X 1 9 WORKFLOW INPUTS HOSPITALS AND PATIENTS
  20. 20. # A L T E R Y X 1 9 DRIVE TIME ANALYTICS SITE SELECTION FOR HEALTHCARE WORKFLOW 20 • Calculate drivetime for every patient to their hospital in terms of: • Average Distance in Miles • Average Drivetime in Minutes • Average Drivetime Distance • Use results to set catchment area drivetime boundaries for current hospitals • Results are also used for future site analytics
  21. 21. # A L T E R Y X 1 9 SPATIAL MATCH WITHIN BOUNDARY 21 • Just as important • Determine patients outside of 15 minute drivetime area • Utilize these to help locate new sites for improved service OUTSIDE OF BOUNDARY • 15 minute drivetime area generated around each hospital location to create catchment areas • Based on previous distance analysis • Patient layer is overlaid onto drivetime boundary WITHIN AND WITHOUT
  22. 22. # A L T E R Y X 1 9 APPEND MOSAIC SEGMENTS 22 • Spatially match Census block group level Experian MOSAIC data to drivetime catchment areas • Obtain count of block groups per hospital boundary • Calculate Top 75% of MOSAIC segments per catchment area using Running Total, Multi-Field Formula Tool and Multi-Row Formula Tool • Determine Top Segments per hospital LIFESTYLE DEMOGRAPHICS
  23. 23. # A L T E R Y X 1 9 TARGET MOSAIC SEGMENTS 23 • Analyze all block groups in metroplex to calculate percentage of similar MOSAIC segments • Filter for block groups with 50% or higher target segments • Results can be used to expand locations throughout study area LIFESTYLE DEMOGRAPHICS
  24. 24. # A L T E R Y X 1 9 THEMATIC MAPS OF TARGET AREAS 24 • Create thematic categories for target percentages: • 50-60%, 60-70%, up to 100% target segments per block group • Overlay patient locations and catchment areas to see distribution • Output using Report Map Tool MAPS AND MORE MAPS
  25. 25. # A L T E R Y X 1 9 THEMATIC MAPS OF TARGET AREAS 25 • Visualize patients outside of 15 minute drivetime catchment areas • Note target MOSAIC segments by block group • New optimal locations may be sited where current patients and high target segment counts intersect • Outreach and development can be focused on specific block groups • Now you can better serve existing and future patients!

  27. 27. # A L T E R Y X 1 9 27 The Alteryx Spatial tools can be used to solve simple/generic problems like how to group spatial objects. They can also be used to solve complex/specific problems like how to comprehensively analyze the locations and demographic profiles of thousands of customers and effectively find a new location that will serve them effectively. MICRO AND MACRO FIVE KEY POINTS Consider ‘wrapping’ existing Alteryx tools for dynamic use Iterative macros in combination with the wrapped macros are extremely powerful Alteryx can incorporate site selection best practices and rapidly produce results Seamlessly integrated demographic and drivetime data speed analysis and output Maps can be generated and modified ad hoc! 1 2 4 5 3
