revert damaging changeset 168343415 which added a loop of footway with very restricted connectivity (when sidewalk data is already mapped) and damaged road alignment

revert clumsy addition of footway connected only to school gate and running alongside but never connecting to publich highways, from ch. 168347764. Not beneficial

revert clumsy addition of badly tagged incomplete footways damaging routing on well mapped highways

better colour choice for building (grey)

set a mid grey-brown building colour

add 3d shape for 200 Aldersgate St, from floor counting from road, others by Mapbox-Esri parallax shifts, heights at 4m/flr

improve building and adjacent way alignments. drop multiple overlapping buildings partly representing height - 3d parts to add

refine 1 London Wall 3d shape w. more curves on SE corner, set some grey colour

add some rough est heights where building:levels alone does not give sufficient control. add some missing colour and material values. re-group more of (former) museum roof areas as parts within a larger building

reinstate position of Marble Hall building after dragged out of position in ch. 168576779 (roof line of non vertical non aligned Bing)

adjust former museum area so that 140 London Wall (offices) is a separate building. remove building tag from museum area, add separate buildings and parts, including cut out ground level for roads

Church building alignment. Cut steps and raised area from pedestrian area. Maintain Highwalks relation (small missing bits)

drop demolished bridgeway and stairs, gone in old station building demolition. set certain parts building:material concrete not glass as rest adjacent. Allow Guildhall Sch building to overlap (in 2d) residential block passing above

add taller pillars for Barbican Centre (and set part for roof between them). Tidy alignment.

resolve another malformed 'multipolygon', was 2 adjacent closed loop part areas, replace with actual multipolygon outer + inner. set actual bulding levels 10 not 7 (2 podium + 1 walkways + 7 resid = 10). alignments

resolve another malformed 'multipolygon' (5 adj loop parts listed as outers) at school, with actual school boundary (Cadastral), actual school outer (1 flr base missing), parts as 2/3 flr areas. adjacent alignments.

restore damaged building shapes, de-scramble objects at level -2,-1,surface (eg u/g platform and ground level shop etc), fix alignments to Cadastral aligned Mapbox. connect platforms to footways, correct scale of 'indoor' features

divide large 2 floor podium building into areas actually 2 floors from ground, separating area over road (with min_height), areas actually 1 floor, areas under sep mapped taller buildings. fix some more malformed 'multipolygon' usage. improve shapes

resolve malformed 'multipolygon' for school (was 2x adjacent building parts both as outer) into actual outer way, with improved part areas. remove steps and buildings from adjacent paving area. improve selected alignments

resolve tagging/mapping of 2 buildings with flying building parts. correct malformed multipolygon (as group of adjacent loop building:parts) to actual outer and inner
