QGIS (formerly Quantum GIS) is a free and open source geographic information system.https://dudodiprj2sv7.cloudfront.net/product-logos/MH/oo/FW9N3U8H9T3U.PNGOpen SourceFree, powerful software for GIS2018-09-18T20:13:11.515ZWithin 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.,QGIS is free and very easy to install, and no license is required. Not having to deal with licensing issues has saved me considerable time and frustration.
The QGIS help community is very active, and it is easy to find answers. Although QGIS does not offer support in the way that ArcMap does, I was always able to google my question and find either a tutorial or website that solved my problem.
QGIS seems to crash less often than ArcMap. It is super annoying to have a program crash when you are in the middle of a project, but I have not had any issues with QGIS. Also, QGIS is updated frequently.,Making maps in QGIS is a bit clunky. I also find it to be extremely unintuitive. For basic GIS, it is great, but I would much rather make maps (for publication purposes) in ArcGIS.
Editing and adding feature layers is not very intuitive. Changing colors of added point or line features is a rather convoluted process.
ArcGIS has a huge selection of online courses, and if you have the appropriate license, you can access most for free. I found these to be very helpful when dealing with map projections and other issues. However, QGIS does not have a large library of courses specifically made for that program.,8,Because QGIS is free, it saves our organization money.
QGIS is easy to install on Windows/Linux/Mac platforms. Our department uses Linux servers, but many of the employees use PCs or Macs. Since QGIS works on all these systems, we can open QGIS projects on any of these systems and continue our work.
The one negative point I have about QGIS is its cartography tools. I frequently have to make maps that are suitable for publication. I spent an inordinate amount of time attempting to make a few maps in QGIS, but I ended up making them in ArcGIS because it was much faster that way. Thus, the use of QGIS sometimes results in a loss of work efficiency due to troubleshooting.,ArcGIS,Eclipse, Skype, Zoom Video WebinarMaike HolthuijzenQGIS gives you a world of options for space processing from the beginning and for free2018-09-05T15:49:51.066ZWe use QGis as a tool aimed at facilitating the management of geographic information for the territorial development of the Bolivarian University of Venezuela. It does this through monitoring, analysis, development and assessment of academic, sociopolitical, administrative and territorial processes in correspondence with regional geopolitical axes. This type of Geographic Information Systems (GIS) structure is an effective tool that allows superimposing geographically referenced information, and visualizes the relationships between the data obtained and the evaluation of the spatial interaction between the information layers represented. In this way, we can reflect, relate and describe geographic phenomena of any kind and their interrelation with the Bolivarian University of Venezuela at the national level.,Documentation and technical support. With this software you will receive all the help you need, if you get stuck in a function you can ask in forums dedicated to QGIS, help manuals including interacting with the help staff.
It is updatable. As some developers share their new creations , the ones that already exist will be updated along with the new, so we know that this software will never be obsolete.
It has support for PostgreSQL and PostGIS extensions. It also allows a file management in vector formats like Grass, Mapinfo, Shapefile, and others, and can also read several raster files in JPG, TIFF GeoTiff, Mapinfo and Grass.
It can be used as a graphical environment for Sig Grass, which uses a large amount of analysis power, using an environment that is easier to understand and use.,The Raster data management is surpassed by ArcGIS, its main competitor. Although QGIS + GRASS put up a good fight, there is always some way in which ArcGIS makes it easier; if not for added values, then due to the difficulty of compatibility of plugins with respect to recent versions.
An online data arsenal for QGIS. With the OpenLayers plugin it allows many background layers but there is not much more.
Have a more friendly and comprehensive tool for accessing plugins, something like a Marketplace, would make things easier, because there are solutions for everything with a specialization focus and should be easier to find.
Statistical tools should be more educational,10,Price: QGIS is available for free for Windows, Mac OS and Linux. It can even be installed on Android.
Cost in employee training: The edition in QGIS is very simple and easy to use.
New functions available in the community: In QGIS you can add new functions through plugins that try to solve multiple daily problems of our own organization.,ArcGIS,PostgreSQL, CartoDB, ArcGISEduardo GuillénQGIS a great solution for nonprofit organizations2018-06-14T17:35:39.848ZQGIS 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.,Demonstrates geographic-centric data for all levels of readers
Makes complicated data more easily digestible and reviewable
Increases the ability to explain data to funders, grantors, and stakeholders,QGIS is hard to use for beginners. A better tutorial and clearer online tutorials could improve this.
Labeling interface is overly complicated. Allowing users to manually add labels to relevant items could be helpful.
QGIS should have more "wizards" that can easily import common data points (median income, population density, etc) and cross tabulate that with other categories easily from uploaded data.,7,QGIS gives us more impactful data on children and maternal health issues, which in turn has helped us establish more programs, relationships, and funding opportunities because of the excellent data presentations we can give.
QGIS has allowed our staff to improve their data analysis skills, improving our workforce across the board, with or without the direct use of geographic data.
QGIS has required a lot of staff time to learn, but the ROI on time spent vs the reports we produced afterward has been well worth it.,ArcGIS,LastPass, IBM SPSS, ArcGISEmber Urbach, LMSWA Great Option for Users of GIS2018-01-19T17:18:06.677ZQGIS 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 manage virtually any kind of spatial data that means you can manage shapefiles, tab files, raster files, cad files, and so many other formats that can help you to make the maps and analyze data in the best way.
With QGIS you can add or modify the tools, for example, if you know some programming experience you can modify the software and include your own tool or extension, this can be very useful if you are an entrepreneur who it is starting to involve in the GIS world.
QGIScome GNU license and that means that anybody can easily download the software on his computer and manage all the information available on the internet of spatial data or share information with other people who manage the software or has some interest of build some applications or extensions to it.,Being an GNU software has some limitations and one of them it is the instability of the software, it can be closed randomly or without any warning and this can be so annoying if you are doing a very hard work, this happens because you do not have any professional customer support, you only have it from other users.
The continuous actualizations can be very annoying because the series bring to fast and you can manage the version 2.14 a little and quickly you can have available, who has not so many modifications and the most of time if not even necessary.
You have to be aware of the data, with GNU license the data that you download can be wrong or cannot have all the information that you need, sometimes you could find errors in "datum" o coordinates you have to be aware because the data that it uses is made all over the world without any supervision, virtually anyone can put wrong data for the users, and you do not know until you work with it.,7,QGIS it is a very useful software to work with spatial data in the way the software helps us to make the plans for maintenance of the urban spaces of the city, we can build this by adding data to the shapefiles and later, selecting which area needs to be prioritized and in what order we have to send the workers to their jobs, and the data bring us the opportunity to do a better use of our personal and budget.
The software is very useful making models of any kind of situation that happens in a city, in our case with the Tranus extension we can see which are the roads with more traffic and can choose which one has to have a regular or continuous maintenance or which one has to be used only two or three times per month, making it more effective for the uses of our resources.
In the planning area QGIS can be so useful because it allows to select which areas of the city has the major budget allocation and why that happens, with this data we can define which areas that need more money to keep in the best possible condition and which ones do not need so much attention from the government, because the actual condition of them it is really good.,,ArcGIS, AutoCAD, MapInfo ProCesar A Siso LPowerful GIS in development2018-03-16T01:19:45.495ZQGIS 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.,QGIS is an excellent open source GIS tool that has been strengthening over the years.
It is not necessary to pay an expensive license to use all the options that it offers us and that is a great benefit, especially to professionals who use the GIS for the development of our work and research
It has a friendly interface, it is very easy to use, especially if you have previously handled a GIS tool.
I also like the great variety of functions that it offers us and that allows us to solve almost any problem.,This software unfortunately tends to be unstable, because sometimes unexpected closures occur.
At times I have had problems because I do not execute certain actions and I must restart the program in order to execute the action satisfactorily.
On the other hand, the quality of the cartographic output is weak compared to other software.,8,You have to invest time in the training of the staff, both for the beginners, as for the users of other GIS software
Improved our response times, which is a benefit for the company
It does not require investing a large sum of money, being a free software
This program tends to be a bit unstable. With large amount of data tends to be slow.,ArcGIS,ArcGISIsabel Huamani
