<ul><li><strong>Priority</strong> changed from <i>Normal</i> to <i>High</i></li></ul><p>Another (more important) reason to solve this (from bug <a class="issue tracker-1 status-5 priority-3 priority- closed" href="https://issues.qgis.org/issues/3825" title="Two decimal places for symbology in map unit is not suited for lat-long data (Closed)">#3825</a> which has been closed as duplicate):</p>
<p>In new symbology, when selecting size, width, offsets etc. in "map unit", the minimum value is either 0.00 or 0.01, because only 2 decimal places are allowed.<br />At 45° North latitude, 0.01 degree=786 meters, which renders symbology based on map unit useless on lat-long data at most scales.<br />It is impossible to chose for instance "0.0001" (about 8 meters) to represent a small road or a track.<br />The resolution should be at least 5 decimal places to support a minimum of "0.00001" (80cm), which makes sense for "street maps" (e.g. with "Open Street-Maps" data in lat-long): sometimes you find a path in very narrow streets, with buildings less than two meters away from each other.</p>
<p>PS: note that OSM data are stored in long lat in decimal degrees with a resoultion of appriximately 1 cm.<br />Because of this bug, currently, it is impossible to create a topographical map on a global scale (i.e. with a global projection system, hence in degrees) with QGIS. Hence I'm raising the priority of this.</p> QGIS Application - Feature request #4217: Allow up to 5 decimal places for Width/Size Scale Fieldhttps://issues.qgis.org/issues/4217?journal_id=277512011-12-16T13:11:24ZGiovanni Manghigiovanni.manghi@gmail.com

<ul></ul><p>From <a class="issue tracker-2 status-5 priority-3 priority- closed" href="https://issues.qgis.org/issues/1238" title="increase the precision of lines/outlines size settings in Symbology (Closed)">#1238</a></p>
<p>_Description</p>
<p>I request that the various Symbology size settings have a precision to at least 4 places to the right of the decimal point, especially the Line width.</p>
<p>Here is why: with only 0.01 precision for Outline width it is impossible to render lines on screen that are exactly one pixel, for example. There will be gaps or two pixel width short segments quite often, which are especially noticeable on straight lines.</p>
<p>I believe that this behavior could cause some annoyance to many users (it annoys me because I can't set a better value that I know would work) and probably complaints.</p>
<p>I know that when a map is rendered to a high resolution printer the precision of the size doesn't make much difference in the result, but it does affect low resolution devices like computer displays.</p>
<p>I have found that a value of approximately 0.26458 for Outline width results in almost no gapping on a typical Windows computer. This may vary depending on platform._</p> QGIS Application - Feature request #4217: Allow up to 5 decimal places for Width/Size Scale Fieldhttps://issues.qgis.org/issues/4217?journal_id=282072011-12-25T11:19:49ZJürgen Fischerjef@norbit.de
