<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d">A bit more background information about the SLD Editor.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d">I’ve been developing the application for about 18 months as a side project. The idea started when we did some consultancy work and put together a proposal for
an organisation to migrate from an Esri system to an OpenLayers/GeoServer stack. When it came to migrating ~1250 layers we didn’t know what number to put down for symbol conversion to SLD. When you looked at the numbers this was a large percentage of the
overall cost and something needed to be done to reduce it if we were going to be competitive in doing migrations to open source GIS systems.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d">One of our long standing large enterprise GIS systems required a change to an SLD symbol which we used QGIS to edit. It turned out there was a known bug that
caused the change to be forgotten. I looked to fix it, I’m very familiar with C++ and Qt but found it difficult to debug and realised the SLD styling data model was not completely implemented.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d">I looked at GeoTools because I knew it could parse SLD files and render them. Another big advantage is that it supports all the GeoServer vendor options, in particular
the labelling. I got something simple working quite quickly and it went from there.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d">Ideally all this functionality should be in QGIS but QGIS would have to be rewritten to use a C++ version of GeoTools to be able to render the GeoServer vendor
options, which will not happen overnight. We know of people that would love this capability and I understand some peoples reluctance for yet another application. I think as long as GeoServer is so heavily used a Java desktop SLD Editor application is acceptable.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d">I’ve had discussions about developing a web-front end for the application, a possibility. However not all GIS systems we deliver are web based and certain projects
I work on and locations I work at, do not allow web access or a web server to be deployed without going through a lot of hoops. If I have a standalone desktop application I can do all my work without having to rely on any other infrastructure. One of the
aims of the application was to be able to work in a connected/disconnected environment, I don’t think all users/developers understand this scenario.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d">The architecture has evolved. I’ve rewritten parts of it several times, sometimes because it didn’t deliver the right functionality or sometimes because I thought
it could be done better (either I had a better idea or trying to improve maintenance), sometimes because I was experimenting. Some parts of the code definitely need to be cleaned up although some frameworks/interfaces I’ve put in-place I think are quite good.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d">There will be some work needed to understand why some symbols don’t display. I’m thinking windbarbs where I believe I’m passing the correct data but the symbol
is not rendered.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Arial","sans-serif";color:#1f497d">I’m also quite keen to progress the GeoPackage standard supporting SLD files. I’m not certain whether the standard supports this yet but GeoTools doesn’t let
me store an SLD file with a vector dataset that I can pass round in one file. The SLD Editor has partially implemented this functionality but it would be better if it was a standard and would probably help increase the adoption of the GeoPackage standard.<u></u><u></u></span></p><span>
