With this light solution, I have no database to maintain. This is also a practical way to compare rapidly any area in the world. This Compare map is used in general for communications about mapping progress. The results are in general satisfactory enough to illustrate the mapping progress. We can provide a more precise measure of progress with statistics of contribution.<br></div><div id="yui_3_16_0_1_1452015743740_17019" dir="ltr"><br></div>The comparizon is in general ok since the FOSM map did not evolve rapidly since the end of 2012, in particular in development countries where HOT and partners have mapping projects. This way we dont need to develop scripts to extract history data end produce map tiles each time we want to make a comparizon for an area. <br><div id="yui_3_16_0_1_1452015743740_12623" class="signature"><span id="yui_3_16_0_1_1452015743740_13616" style="font-style:italic;color:rgb(0, 0, 191);font-weight:bold;"> <br><font id="yui_3_16_0_1_1452015743740_13617" face="garamond, new york, times, serif">Pierre </font><br></span></div><br> <div id="yui_3_16_0_1_1452015743740_12873" class="qtdSeparateBR"><br><br></div><div style="display: block;" id="yui_3_16_0_1_1452015743740_12877" class="yahoo_quoted"> <div id="yui_3_16_0_1_1452015743740_12876" style="font-family: verdana, helvetica, sans-serif; font-size: 13px;"> <div id="yui_3_16_0_1_1452015743740_12875" style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, linéale; font-size: 16px;"> <div id="yui_3_16_0_1_1452015743740_12874" dir="ltr"> <font id="yui_3_16_0_1_1452015743740_12878" face="Arial" size="2"> <hr size="1"> <b><span style="font-weight:bold;">De :</span></b> Andrew Wiseman <awiseman@gmail.com><br> <b><span style="font-weight: bold;">À :</span></b> Pierre Béland <pierzenh@yahoo.fr> <br><b><span style="font-weight: bold;">Cc :</span></b> Pete Masters <pedrito1414@googlemail.com>; "hot@openstreetmap.org" <hot@openstreetmap.org><br> <b><span style="font-weight: bold;">Envoyé le :</span></b> mardi 5 janvier 2016 13h47<br> <b><span style="font-weight: bold;">Objet :</span></b> Re: [HOT] OSM before and after<br> </font> </div> <div id="yui_3_16_0_1_1452015743740_12879" class="y_msg_container"><br><div id="yiv5722049763"><div id="yui_3_16_0_1_1452015743740_12881"><div id="yui_3_16_0_1_1452015743740_12880" dir="ltr">These tools are really cool!
