QGIS for Mac 3.8.3 Short Description QGIS supports vector, raster, and database formats and lets you browse and create map data on your computer. QGIS supports many common spatial data formats (e.g. ESRI ShapeFile, geotiff). This vignette guides you through the installation process of QGIS, GRASS- and SAGA-GIS on three different platforms (Windows, Mac, Linux). Please use the long-term release QGIS 2.18. So far, RQGIS does not work with QGIS 3. Following our instructions should ensure that RQGIS will work properly. As many probably know, the MacOS installer for QGIS is not as turnkey as the windows version. You have to basically install 3-4 sets of packages, only one of which end up in the Mac apps directory (e.g., GDAL). If I want to completely uninstall QGIS, how do I go about uninstalling the packages like GDAL?
As of QGIS v. 1.5 (2010) the stand-alone ‘all in one’ bundle for Mac OS X is no longer supported. Installation requires dependent frameworks, each with their own requirements, to be installed in order before the installation of QGIS.
- QGIS is an official project of the Open Source Geospatial Foundation (OSGeo) and is a volunteer driven project. It runs on Linux, Unix, Mac OSX, and Windows and supports numerous vector, raster, and database formats and functionalities.
- QGIS is an open source option for GIS software. There are many benefits to using QGIS including: The software is free. QGIS is easy to learn if users are familiar with ArcGIS or with GIS concepts. QGIS can be used on a Mac OS X because the software is multiplatform.QGIS can also be used on Windows, Linux, BSD Unix, and Android.

Here are revised (2015) instructions for installing QGIS on a Mac
A while back I reviewed MyWorldGIS, indicating my disappointment with the analysis capabilities of other available free or low-cost GIS for the Mac. Well, no longer. Since its birth in 2002, Quantum GIS (qGIS) has grown to be an impressively powerful application in its own right.
qGIS is an Open Source Geographic Information System (GIS) licensed under the GNU General Public License. QGIS is an official project of the Open Source Geospatial Foundation (OSGeo) and is a volunteer driven project. It runs on Linux, Unix, Mac OSX, and Windows and supports numerous vector, raster, and database formats and functionalities. In this review I’ve chosen to highlight its Mac-ness, both because I am a Mac user and I am often asked about Mac GIS options.
Over its life-cycle, qGIS has dished out a continously growing number of capabilities provided by core functions and plugins – and appears to be still growing strong. You can visualize, manage, edit, analyze data, and compose printable maps. Best of all (in my opinion) is a robust set of vector data analysis, geoprocessing, geometry, and data management tools and functionality now available. Sometimes open-source software gets a bad wrap for being too complicated, particularly in the graphical user interface (GUI) department. It is what it is – made by techies for techies, qGIS is a growing powerhouse of geospatial tools, though it might not win GUI awards for simplicity. Did I mention it is also free?

Overview of qGIS Features
First let’s get acquainted. A summary of features include:
- View and overlay vector and raster data in different formats (including GIS shapefiles) and projections without conversion to an internal or common format.
- Create maps and interactively explore spatial data, including on the fly projection, spatial bookmarks, identify/select features, feature labeling, change vector and raster symbology, and more.
- Create, edit and export spatial data, including GPS tools to import and export GPX format, convert other GPS formats to GPX, or down/upload directly to a GPS unit.
- Perform spatial analysis using the fTools plugin for Shapefiles.
- Publish your map on the internet using the export to Mapfile capability (requires a webserver with UMN MapServer installed) Omnisphere 2 crash when activating.
These Are a Few of My Favorite Things
As a disclaimer, I typically use qGIS to explore shapefile data, manipulate data, and save selections of shapefiles to prepare them for import into our Ortelius cartography software (to which I am affiliated). My review is clearly influenced by these uses and by the questions we get from our own users wanting to do more with GIS.
qGIS Stand-Alone Installation
On the downside (or upside – depending on your point of view), there are a lot of download options. First, there are separate downloads for each operating system. Each also has a variety of dependancy frameworks with their own requirements. The standalone Qgis does not include GRASS support at all, if you want it you must use the standard Qgis package + frameworks + GRASS if you need GRASS features (GRASS is a GIS used for geospatial data management and analysis, image processing, graphics/map production, spatial modelling, and visualization – it is not required for qGIS though can provide added functionality). Wowza. This might leave many potential casual users puzzled before they even have the software!
Have no fear – a stand-alone installation ‘all in one’ bundle for Mac OS X is provided for “new users.” In fact, I highly recommend it for all but very technically-minded and advanced users.
Analysis With fTools qGIS Plugin
Do you need to count the points of one layer in polygons of another layer? Select by location? Buffer or intersect features? Convert feature geometry?Join attributes with an external table? Or more? If so, you definitely need analysis tools. Choose Plugins > Manage Plugins… from the main menu and enable the fTools plugin for data management and analysis. Doing so will add “Vector” to the main menu and provide a variety of tools for manipulating your vector GIS data.
I am often asked about software to join external spreadsheet data with GIS data. To do this, you need a common data field, such as country name, in both data sets. Choose Vector > Data Management Tools > Join Attributes from the main menu to identify your target GIS layer, join field, and database file to join. Note that you cannot directly link to Pages® or Excel® spreadsheets, rather you must link to a DBF file. This is especially a pain since Excel (Mac 2008) stopped having a DBF export option. I have turned to using open-source software NeoOffice to convert my spreadsheet data to DBF to prepare for linking attribute tables. It is an inconvenient step, so if you have a better solution for Mac users, please share! Once you’re done, the automatic save of the output shapefile makes things especially easy.
X,Y Data to Shapefile
Lots of people have X,Y coordinate data (e.g., latitude/longitude data) in spreadsheet format that they want to display on a map. In fact, if you have a simple address list, you can use a service such as BatchGeocode.com to generate your X,Y data for you, then use the results to create shapefiles in qGIS. First choose Plugins > Manage Plugins… from the main menu and enable the Add Delimited Text Layer plugin. In the main menu, the Plugins menu will now list “Delimited Text” among its options. Use the GUI to import your tab delimited X,Y data.
Vector Editing
qGIS supports editing the points, lines and polygons of shapefile map data. Choose Layer > Toggle Editing to activate the editing toolbar. qGIS has a suite of editing tools to cut and add features. https://newic892.weebly.com/mac-os-high-sierra-windows-download.html.
Save Selection as Shapefile
Perhaps I use this most – I simply love the ease of which you can select features in a layer and save them as a new shapefile. Use the Select Features tool from the toolbar to directly select features on your map, or open Attribute Table and select features from the table view. Then, simply choose Layer > Save Selection As Shapefile form the main menu. It’s as easy as that and a powerful tool when pairing down large shapefiles to your area of interest.
Conclusion
While there are a plethora other features that could be mentioned, these are among the ones I use the most. On the down-side, the cartographic rendering in qGIS is typical of a low- to mid-range GIS programs (unfortunately which can easily produce ugly GIS-looking maps). Although packed with features, the program can be overwhelming for new users who are just getting started with GIS. If you are in that lot, the provided Users Manuals are required reading. I find the GUI a bit cluttered with buttons, such as the five different buttons for importing a layer when one might suffice. Organization in the GUI might also be improved by consistently locating active plugins – either by adding active plugins to the Plugin menu or as separate menu items, but not both – it can be confusing when you activate a plugin and it isn’t where you expect it to be.
Overall, qGIS is a strong performer with a dedicated volunteer development base. Kudos to the development team for continuing development on this much needed application. It gets high marks in analysis and data management and I recommend it for Mac GIS users.
There are unlimited uses of GIS software in general, and qGIS specifically, that I haven’t covered. Do you have experience with qGIS you’d like to share? Do you have experience with other GIS for Mac tools? If so, I’d love to hear from you.
This tutorial presupposes you have installed QGIS for Mac. If not, full instructions and downloads are available on the KyngChaos page. Obtaining a GIS package from a website called “kyngchaos” sounds dodgy, rest assured that it is the method approved by the QGIS developers themselves.
Qgis For Mac Os Sierra
You may have already performed some of these steps; there is no need to repeat them if you have done so. Windows 10 pro lite x86 iso download.
- Install Homebrew for mac if you have not done so already. Homebrew has great utility beyond QGIS.
- Install wine using homebrew
brew install wine
- Install XQuartz. XQuartz is a windowing system (if you know unix, it’s X) for Mac. If you are using an old Mac, it is probably already installed, but updating to the new version will not hurt. XQuartz is required because it is used as the windowing system for Microsoft Windows and Linux applications.
- Download and unzip lastools. Remember where you unzipped it.
- You’re almost done. Start QGIS. Select Processing/Options. In the Providers section scroll to “Tools for LiDAR Data”. Fill out the blanks:
- LASTools folder:
pathtolastoolsdirectory
- Wine Folder:
usrlocalbin
Note: this is the default directory for the homebrew wine installation. If you want to check to make sure it’s correct, open a terminal (ie, Terminal app) and type:
which wine
The output will tell you what to type in the box. Remove the ‘wine’ part of the entry.- Restart QGIS. When you open the toolbox, you should have all the LAStools available in your toolbox.
https://keenmother.weebly.com/odbc-administrator-for-mac-os-x.html. Note: When you open one of the LAStools for the first time you will see a large number of error messages, etc. These are from wine and can be safely ignored.
Qgis For Mac 10.10.5
Subsequent tool usage will be faster and have fewer errors, but there may still be some. If there are errors, they can be safely ignored as long as the LAStools are functioning.
Another note: When using some of the LAStools (like lasviewer), you will note that the processing toolbox dialogue does not disappear, making it look like QGIS has crashed. This is not the case – the wine window (ie, that which is displaying the lidar data) is part of the tool, and the processing dialogue box will close once you close the lidar window.
New for QGIS 3.x
LASTools are no longer enabled by default. To enable LASTools, follow these steps:
- Go to Plugins/Manage and Install Plugins
- Search for LASTools and install the plugin
- Once that’s done, LASTools (as opposed to “Tools for LiDAR Data”) will appear in the Processing Options, where you must check the “enable” button and follow the steps above.
