Qgis is the main option we have as GIS software users for the development of our daily work activities. Qgis offers a wide range of tools and options for the generation of thematic cartography, spatial analysis, and image analysis from remote sensors. Qgis, being a GNU program, allows generating links with many software, so that information can be generated in a different software and then linked and visualized with Qgis. The tools are quite intuitive, and in addition to that, the software allows the use of multiple formats such as shapefile, prj, mapinfo layers, binary coverage, raster, tab-delimited text, and many more, which considerably broadens the spectrum of information that can be handled with this tool.

The software has a major disadvantage, which is that in many cases it can be very unstable, meaning it can close suddenly, generate errors in the processes, or simply not address problems adequately. In addition to that, the initial opening of the program can be somewhat overwhelming, as all the tools appear displayed, and that can be a bit unsettling, given that a user does not necessarily need all the tools the program presents. Some tools like the Open Layer are excessively heavy and require a high-speed internet connection to be used. Review collected by and hosted on G2.com.

The Open Source Geographical Information System that has evolved the most, has more compatibility, adaptability and better output design.

GRASS, SAGA, OPENLAYER and OPENSTREETMAP are compatible with QGIS

QGIS presents a set of very complete vector and raster analysis tools and gives identical results to the analysis packages of the private software, with the difference that QGIS allows to see and manipulate the mathematical models that support these formulas.

You can do TIM, program in Phyton, create a web map, link GRASS or SAGA processes Review collected by and hosted on G2.com.

In some opportunities, the software can hang by managing localized databases with many records Review collected by and hosted on G2.com.

It is free, it has awesome plugins. It has a big community of developer and users. Review collected by and hosted on G2.com.

Processing large raster data is a pain and it crashes very often. Review collected by and hosted on G2.com.

In my opinion, i'ts the best free GIS on the market. Not as powerful as ESRI tools but very useful and with a variety of tools and processes. Review collected by and hosted on G2.com.

Its working environment looks a little childish, what can make your work looks similar. Review collected by and hosted on G2.com.

QGIS has the ability to use practically any data format that can handle spatial data, the program allows the use of shapefiles, tab files, CAD files, raster files, and many other file extensions that enable compatibility with any software available in the market, and allows the user to perform tasks in QGIS and manipulate or modify them in other programs. QGIS has a great capacity for adaptation, given that it is licensed under GNU, it is possible to manipulate the program's functionality and adapt it to the needs of each company or user, so that each person using QGIS can manipulate the interface and activate the tools that are truly useful and discard those that are not necessary. Additionally, the user can add their own tools that can be very useful for their daily tasks. Review collected by and hosted on G2.com.

Being free software has many advantages, but also a large number of disadvantages, the main one being the instability of the program; on many occasions, it can close or stop working suddenly, which can be quite annoying and can also slow down work significantly. Additionally, there is no direct technical support, but rather collaborators who ensure the program works and remains operational. However, many questions the user must resolve on their own, which can be quite complicated in some cases. Review collected by and hosted on G2.com.

I love that it’s free and easy to use if you already know arcGIS. Mapping software can cost a lot of money so it’s awesome that this is 100% free. It can be difficult to navigate if you aren’t familiar with arcgis. I also enjoy that you are able to geocode using google maps right through a plugin. Review collected by and hosted on G2.com.

While it’s easy to figure out it does differ significantly from arcMap. Review collected by and hosted on G2.com.

The open source aspect, and the fact that it's free! Review collected by and hosted on G2.com.

Because of the fact that it's open source, it has a little less support, and crashes a bit more than ArcMap. Review collected by and hosted on G2.com.

Adding different data types with different extensions is very easy. QGIS provides various basemaps with the OpenLayers plugin. Review collected by and hosted on G2.com.

Vector analysis tools processing takes very long compared to other GIS softwares. On Review collected by and hosted on G2.com.

I like that the software is accessible to all price ranges Review collected by and hosted on G2.com.

It isn't quite as streamlined as ESRI products. Review collected by and hosted on G2.com.

Free, easy to use if you've already used ArcGIS before Review collected by and hosted on G2.com.

Not always stable, sometimes shuts down suddenly for no apparent reason. It's a lot quicker to create maps in Tableau if you have it. Review collected by and hosted on G2.com.
