Hello Ian Happy and Prosperous New Year Thanks for taking time to quickly check our edits and share feedback.
Here are our observations on the findings - 1 iffy change-set which deleted all roads in Carnasa/Carnaza Island in northern Cebu https://www.openstreetmap.org/changeset/65332385 Roads in this change-set were created by our editor in an island without any connectivity(Isolated), hence, were deleted during our internal validation(Quality check). We were not sure if roads can be created and left in isolation. We have such instances in other cities of Indonesia which could be connected through ferry route, but we are not creating such roads as we are not clear on the connectivity basis satellite imagery. 2. Deleting and re-creating a feature, as what happened to the area around the Magellan Shrine in Lapu-Lapu City - Existing road was partitioned as it was initially created as a loop. <https://lh3.googleusercontent.com/-pccscY1Vgho/XC7FczFQFdI/AAAAAAAACUc/ycj8ggtWHo0f90UKJCqoDNu15msqLmvSACL0BGAYYCw/h473/2019-01-03.png> It infact was not deleted and re-created, but a partition made <https://lh3.googleusercontent.com/-pVAp27Z6zic/XC7FqhBUAVI/AAAAAAAACUc/qtkepcM4I7U68-ftwLZ4Iz7bGBD8OeMwACL0BGAYYCw/h461/2019-01-03.png> which might have led Osmcha to represent it as deleted segment As you rightly mentioned our edits are focused on road geometry - creation and modification(alignment and attribute corrections of existing data as appropriate following OSM guidelines) Kindly suggest if we are missing anything Thanks GrabTeam On Thu, Jan 3, 2019, 19:46 Ian Lopez <[email protected] wrote: > Hello and happy New Year to all. > > In the wake of issues between OpenStreetMap contributors in Thailand and > editors from GlobalLogic [1] I've decided to review a selection of edits > in the Philippines done by the GlobalLogic team over the past 12 months. > > As soon as I started my review, I immediately spotted at least one iffy > changeset [2] which deleted all roads in Carnasa/Carnaza Island in > northern Cebu.
