QGIS Reviews and Ratings

Use Cases and Deployment Scope

I work constantly with geoprocessing products, and QGIS is fundamental for all phases of this work, from data collection to the final result. Displaying originally textual data (albeit with a spatial reference) on maps, and then analyzing (quantitatively and qualitatively) those maps are the main reasons to use this software here at GISMarxev.

Finally, the possibility of printing and exporting the map to various formats (PDF, JPEG, SVG) with the help of tools that add even more information (scale rulers, wind roses, titles and legends, etc.) free and open source, are decisive for choosing QGIS.

Use Cases and Deployment Scope

QGIS is open-source software that can create, edit, store, analyze, visualize geospatial data. In our organization, we used QGIS for the interpretation and analysis of the satellite images for the application related to Climate Change, Mangroves analysis, Land Use, and Landcover Analysis, Watershed analysis. QGIS software is also used for network planning, route optimization, and creation of Vector data. QGIS software can be used for various applications such as Urban Planning, Environment Conversation, Hydrographic Analysis, Transportation planning, etc.

Likelihood to Recommend

QGIS is well suited to create, analyze and interpret, visualize and store Geospatial Data. It can be used for multiple applications from Urban Planning, Climate Change Analysis, Forest Mapping, Site Selection, Risk Analysis, etc. QGIS is not suited when data doesn't have location information. Although users can add location data into their data using QGIS.

Use Cases and Deployment Scope

Similar to RStudio, QGIS allows any user within our organization with an interest in map-making and spatial analysis to explore data and produce results without needed to go through corporate hoops to get access to commercial software. It allows for the democratization of GIS skills across the organization, without the need to silo it to a few people that would make the most of a commercial license.

Whenever I need to produce a presentation-ready map I will use QGIS and either produce a full layout from it or just export the map as a bitmap. I often hear back from colleagues asking how I made such a nice map as many don't have experience with GIS software. QGIS is not a "wizard-type" tool, and the number of options can be overwhelming to a number of users. This being said the same could be said of most GIS applications, Google Earth being maybe the one with the lowest barrier of entry, but also the most limited in terms of producing polished outputs.

Use Cases and Deployment Scope

We use QGIS to do spatial analysis of large property datasets, develop styling for thematic layers, convert the styling into SLD format to use in Geoserver, and build monthly reports for our clients of the results of their spatial analytics. QGIS is our go-to tool for working with spatial data. We also recommend it to local government/municipalities who are our clients, as a functional and cost-effective replacement for other proprietary GIS packages. By reducing licensing costs, organizations can spend the budget on appointing more spatial analysts or even developers to customize the application to suit their unique requirements.

Likelihood to Recommend

QGIS should be the tool of choice for any taxpayer-funded institution, like a municipality of a governmental department. The GIS budget can be spent on employing developers and GIS analysts rather than just siphoning it out to multinational corporations. The staff can then work on improving the product for all users globally, and pretty soon we'll have an unbelievable product that does great good for management.

QGIS is perfect if you don't use GIS absolutely every day, because it is free software, and offers pretty much anything that you can do with proprietary software.

I don't think QGIS has such amazing 3D capabilities yet (although it does exist, and maybe I'm just not proficient enough in its use yet).

Use Cases and Deployment Scope

QGIS is the go-to tool for us to work with the spatial files. It is being used to create and modify shapefiles, generate spatial data, and create maps. We have been using it to add or remove layers in the shapefiles and extract data to and from SQL Server.

Likelihood to Recommend

QGIS is very well suited for simpler operations like editing, modifying shapefiles, labeling and coloring it, changing projections. But if you want to export or import data to and from SQL databases, you need to OGR and that's a bit of a hit and miss because of the version incompatibility and whatnot.

Use Cases and Deployment Scope

We use QGIS to visualize US election data sets. We are focused on Florida, and Congressional District 17. We publish maps of registered voter demographic data such as age groups, race, gender, and turnout. We also use QGIS for strategic mapping of voter precincts to better target volunteers and canvassing. The majority of our maps are proprietary.

Likelihood to Recommend

If you don't have access to ArcGIS, QGIS is great. It's cross-platform, open source, and free to download. For our purposes it gets the job done. If we had the money we would seriously consider upgrading to the ESRI products for more features. The QGIS ecosystem is widely supported online in forums. We are not professional cartographers, but we were able to figure it out and produce professional-looking maps for our clients.

Use Cases and Deployment Scope

Within my department, we do a lot of GIS. About half of my coworkers use ArcGIS and half use QGIS. QGIS addresses the problems associated with licensing. It is open source software, so no licensing is required. It is also much easier to install than ArcGIS and (in my experience) crashes less often than ArcGIS. Less crashing and faster install times result in more efficiency and productivity.

Likelihood to Recommend

QGIS is great for companies or individuals who are on a budget but still need powerful GIS software. QGIS is excellent in that it can consume many data formats and basically has all the same capabilities as ArcGIS. In addition, since QGIS is cross-platform it is Linux and Mac friendly, making it more versatile than ArcMap, which only works on Windows machines. In my opinion, it is a little less beginner friendly, so I'd recommend it more to those who have some previous experience with GIS. I would, however, not recommend it for those who mainly want to create maps. I found the map making feature in QGIS very cumbersome.

Use Cases and Deployment Scope

QGIS was used by select researchers who utilized the mapping software for social and economic data visualization in line with our organization's mission and views on children and adolescent health. This is a low cost/free option for us to create reports and tools for grantors and funders, as well as legislators.

Likelihood to Recommend

QGIS is a great alternative to expensive GIS software for non-profits and new users who are looking to enhance their data visualization and reports to stakeholders. Organizations who are afraid to make a jump and invest in comprehensive GIS software should feel safe and comfortable giving QGIS a try and introducing employees to GIS information software to help improve how they use and learn from data.

Use Cases and Deployment Scope

QGIS is a very complete tool for spatial analysis as well as the elaboration of topographic and thematic cartography. It seems to me an excellent advantage that QGIS allows the connection with R, which is also open source statistical software, allowing to directly relate the data of the various variables with their spatial location.

Likelihood to Recommend

It's a very good GIS tool. It is a free software that has had a rapid development, it can even be compared with other GIS proprietary software of world reknown.

QGIS allows you to download a large number of add-ons developed by other expert users, which are available to all for free.

In addition QGIS accepts multiple formats such as shapefile, mapinfo layers, binary coverage, raster, among others, which gives the user the facilities and ability to work with the information available.

Use Cases and Deployment Scope

QGIS has helped us to make all the cartography and maps to do the spatial analysis or urban areas, with the tools for edit, create, customize and print, we have build maps of the entire city emphasizing the maintenance of the highways, sidewalks, and recreational spaces. The software is used only in the planning area with some implications in others spaces like administration or any office who needs gathering information some particular place or of a specific category of urban space. Qgis it is a really good tool to makes plans, organizes information, manages spatial data, makes maps, and for explaining the people who work in the company or general public which are the places where we need to act and how these are distributed in the city.

QGIS can be a tool for beginners or for users who are not familiar with a private software, the interphase it is very easy to manage, and you can have no problems working with a variety of files like cad, shape or tab because the software allows all. For people who it is starting with GIS this the best to get a basic knowledge and start to develop their abilities.

The users, especially the new ones have to be aware of the dysfunction of the free software, some versions can be very unstable and bring some complications in the middle of a job, you have to be aware of the data and where that data comes from, that data can be wrong or have so many mistakes. Another consideration is related to the basic knowledge of programming language if you do not know a little you can have some troubles because to do a modification in the software you have to know a little about programming.
