<div dir="ltr">I have a python script which will analyse all buildings in a bounding box and output those with a large "skew" - where the diagonals don't match (within a tolerance). It uses overpass API and will also output changeset/user info. I'll post a link to it tomorrow once I've finished user options. Might be useful to identify tiles where buildings aren't square. Needs overpass and pygeo to get data and work out distances. jon.</div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, May 5, 2015 at 7:05 AM, kusala nine <span dir="ltr"><<a href="mailto:kusala9@googlemail.com" target="_blank">kusala9@googlemail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>I put the latest extract back into a database last night and extracted just the buildings and the number of sides in them - the list below shows total number of buildings and the number of sides in the polygon.. Of the 190k buildings in the current Nepal extract the vast majority have four sides - There are 58 triangular buildings though! and quite a lot with more sides. I am analysing the 4-sided buildings now and measuring the difference in metres between the diagonals - this is probably the best method of determing the skew. If you want a shapefile of the triangular buildings let me know and I can dropbox it. I'll try and get this working in python/overpass wrapper so it can be run as a validation process... jon.</div><div><br></div><div><font face="monospace, monospace">total | #sides</font></div><div><font face="monospace, monospace"> 160852 | 4</font></div><div><font face="monospace, monospace"> 10940 | 6</font></div><div><font face="monospace, monospace"> 6259 | 5</font></div><div><font face="monospace, monospace"> 5075 | 8</font></div><div><font face="monospace, monospace"> 2404 | 7</font></div><div><font face="monospace, monospace"> 1240 | 10</font></div><div><font face="monospace, monospace"> 875 | 9</font></div><div><font face="monospace, monospace"> 718 | 12</font></div><div><font face="monospace, monospace"> 496 | 11</font></div><div><font face="monospace, monospace"> 231 | 14</font></div><div><font face="monospace, monospace"> 208 | 13</font></div><div><font face="monospace, monospace"> 179 | 16</font></div><div><font face="monospace, monospace"> 128 | 15</font></div><div><font face="monospace, monospace"> 82 | 18</font></div><div><font face="monospace, monospace"> 72 | 19</font></div><div><font face="monospace, monospace"> <b> <font color="#cc0000">58 | 3</font></b></font></div><div><br></div></div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br><div class="gmail_quote">On Mon, May 4, 2015 at 10:23 PM, kusala nine <span dir="ltr"><<a href="mailto:kusala9@googlemail.com" target="_blank">kusala9@googlemail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">hi - will do. back to the day job tomorrow but will keep on it. geometrically it's easy to figure out if something's got right angles - it's just the extract from the database.
