![]() ![]() This map shows some familiar layers from the previous module. Open the project named Chapter_7_Map Composer.qgs in the QGIS for Disaster Management directory. Let’s start with some data in the Sleman regency that has already been symbolised.Apart from the map, you are able to add additional information such as images, labels, legends, and scalebars. If or when I ever decide to do a second edition I’d love to fix the errors that areĬurrently present.The QGIS Map Composer allows you to prepare it for printing. GitHub - The buildings and some of the land use symbology was taken from this amazing repositoryĪ nice part about being able to release my work is getting feedback.OpenData Ottawa - For neighbourhood locations, city parks, and airfield outlines.Natural Resources Canada - CanVec 1:50 000 scale vector data.Data Sourcesĭata for this map was graciously provided by: I may even make it a project to write a simple plugin to help with automating some labelling tasks in the future. Labelling in QGIS has a lot of potential, and I look forward Then you are able to move and rotate your labels (only if you’re not using rule-based labelling, as far as I saw). The current way to manually adjust labels requires you to create attribute fields (X, Y, and rotation), setting the label placement parameters to be data-defined from those fields, If I was able to edit the export in Inkscape or Illustrator this wouldn’t be as big of an issue. It seems I’m not the only person to have this issue. ![]() I ended up taking the image and processing it at work as editing 2 GB images on my lowly home PC was not a lot of fun. To solve this I ended up exporting as a very high resolution (550 ppi) TIFF image, and doing the post-export touch ups in Photoshop, instead of Illustrator or Inkscape like I I discovered that whenever I tried to export a PDF from print composer with the lat/lon graticule visible it would disable exporting vector shapes and force it to export as a raster. These would not render in the QGIS print composer.Ĭreating a new, blank print composer that was significantly smaller in size than my final export fixed this, so I wonder what setting is responsible for this. Symbols I demonstrated in my ArcMap Tips post. I originally planned on using an inner glow effect for the water, similar to the gradient fill While the draw effects I mentioned above are really neat, they’re only useful if they render in the export. The glow effect the water features in the map had in QGIS. Cons of using QGIS My Draw Effects Didn’t Export QGIS is much simpler and faster to build symbols,Īs well as pick and save custom colours. I think I counted up to six to change the line colour of a leader line for a label. If you’ve ever tried to create complex custom symbology in ArcMap you’ve likely decided to count how many windows you have to click through to change These draw effects render fast, and make it easy to add a bit of flair to your map. The bottom layer of a multi-layered line symbol). You can give an effect to an entire layer, or only to certain parts of a symbol (for example giving an outer glow to just Inner glows, and even geometry transformations. QGIS has support for neat draw effects for most vector symbols in your map, including drop shadows, outer glows, Think of sizing my map symbols in metres rather than points. After I got used to the idea, it was much easier and intuitive to The conceptual difference is huge, instead of thinking to size my road labels at 6 pts in aġ:20 000 scale data frame, I need to symbolize them to be 15 metres tall at whatever scale I’m viewing them at. Unlike in ArcMap, where you can set a reference scale for all the layers in yourĭata frame, in QGIS you must symbololize your layers in map units. Pros of using QGIS Map Units vs Reference Scale The final print was done at 42" x 36", mounted on 2" x 1" oak boards and hung in my office. The high quality PDF, which can be printed at 42” x 36”, or a lower quality JPEG below. It’s displayed below using the OpenLayers web mapping library. Geo-referenced web mapping tiles, or raw image tiles. I scaled down the final export and ran it through gdal2tiles, which takes an input image and transforms it into either ![]() For school and work I had exclusively used ArcMap, so trying out and getting used to the many differences Since I started learning about GIS in 2011 I had only read the odd news article or experimented once or twice with QGIS, aįree and open source GIS suite. Over the winter my girlfriend and I got a place together, and I wanted to create a nice map to put up on our wall. ![]()
