Turns out interstice is a much better M25 viewer - if you select right axial maps. 

1. Compute EMD for M25 London (best EMD comparison)
2. Compute Point synergy M25 London
3. Compute Point intel M25 London
4. Compute Steven Read measure M25 London
5. Compute Choice M25 London
6. Do code for chi test 
7. Try  clustering data for Chi test
8. Compute against the new average radius finding mechansium. 
9. Get comparative pictures for M25 for Bills segmental measures (depthmap - check paper)
10. Might want to compute east end of london as example 
11. Compute new EMD for Boston
12. MIGHT want to code up faster intersection mechanism. 

Export centred  M25 map to Illustrator for test ( might try scale to). Back home by Chirstmas chaps.
