Free and easy to use

Commentaires : Qgis is one of the most complete geographic information processing software out there today.

Avantages :

It is an open access software with regular updates available to everyone. Its compatibility with various graphic and semantic information input formats make it a powerful tool for managing geographic information. The management of information in raster and vector formats make Qgis a versatile system, suitable for applications in many themes. The possibility of using web maps as a base or in the representation of the results allows a better visualization of the information.

Inconvénients :

Some initial training is needed, once the first steps are taken it is easy to use.

Best open-source software for geospatial mapping!!

Commentaires : QGIS is open-source software that can easily download and deploy. It consists of a variety of plugins and tools to work with geospatial data.

Avantages :

QGIS is totally free software that helps us to perform spatial analysis, data management, geospatial data preparation, satellite data interpretation, etc. This software is updating day by day and adding very important plugins and features to it. QGIS has plugins to connect with other platforms too. For example, Send2GoogleEarth plugin can join with Google Earth Pro, Google Earth Engine Plugin can work with GEE platform. This software provides plugins and tools for quick land use classifications compared to other GIS platforms. Digitization of spatial elements like buildings, roads, streams, and land cover is very comfortable with QGIS. QGIS has the facility to load base maps such as OpenStreetMap, Google Hybrid, Google Satellite, Google Road, and Bing Arial by adding the URL. This service is very valuable for those who are working with base data preparation and interpretation.

Inconvénients :

QGIS doesn’t support adding data from file geodatabases. Sometimes QGIS is unexpectedly ended due to crash reporting. Especially at the time, we are doing digitization activities using google satellite images.

new user 6 month

Commentaires : My somewhat recent experience with the program is to solve the problems of the layers that I used to export to and from other expensive programs, which I am doing now with the free program

Avantages :

The program is completely free, light and easy to handle with features

Inconvénients :

The permanent development of the program and keep abreast of the development that occurs with all programs and devices, and it is free

Best GIS software for beginners

Commentaires : A great GIS software that is available to download free of cost. It provides large number of third party tools and plugins for faster data manipulation and analysis.

Avantages :

Best software for beginners and easy to install. QGIS is a powerful tool for custom geoprocessing to identify trends within the spatial dataset and create professional looking maps, free of cost. Able to handle complicated datasets easily. Allows easy task automation to schedule jobs on a daily basis.

Inconvénients :

The software can be a bit unstable and slow while performing heavy tasks, and fails to efficiently manage raster data unlike other GIS software available.

Powerful, reliable, easy to use, extendable... and free (as in free beer and free speech)

Avantages :

It is extremely powerful: it has plenty of built-in algorithms that range from data analysis, visualization, vector, raster... and it has thousands of 3rd party plug-ins that extend their base functionallities. Furthermore, if everything fails, it can be extended through python scripting. As result it can be used for any purpose that include geospatial data. Furthermore, it is reliable, meaning that it does not hang when working with large datasets or doing complex calculations. The fact that can be used in any major Operating System (GNU/Linux, Windows, Mac, Android) and can read and write a number of file formats (including, but not limited to, all open standards) makes it excellent for sharing your work with others, preventing any kind of platform lock-in.

Inconvénients :

It might be not well-known as Arcgis, even though it can do everything Arcgis can do plus more, at a fraction of its cost (0).

Review of QGIS

Commentaires : QGIS is very useful software in the Geoinformatics field.

Avantages :

QGIS is free and open-source software. QGIS supports all possible formats such as raster, vector, point clouds of GIS, and Remote Sensing. QGIS is highly customizable and the Developer can develop various plugins as per requirements.

Inconvénients :

QGIS sometimes encounters a bug and immediate Support is not available. QGIS needs more tools for raster data processing.

Great software in what it proposes

Commentaires : I have been using the program for more than 6 months and even then I have no interest in changing software, as it perfectly meets my map creation demands. I can create everything from less complex maps for personal use, to maps for professional use.

Avantages :

The main benefit of QGIS in relation to competitors is related to cost-benefit. The software is compatible with the most popular operating systems such as Windowns, Linux and Mac. A few months ago I started a course to become professional and 4 months ago I got a new job opportunity thanks to my knowledge and skill with the tool. In addition, QGIS support is very complete, where I can solve problems in a short time. It is possible to download different versions of the program, depending on each demand.

Inconvénients :

Comparing QGIS with some similar but paid programs, it is possible to notice that some problems happen more frequently, where the software proves to be more unstable and sometimes the program closes for no apparent reason, however, these are quite sporadic situations and do not affect my Yield.

A fantastic open source replacement for expensive proprietary solutions

Avantages :

If you need a GIS Desktop tool, QGIS is the way to go. It is rich of features, open source, and easily customizable using Python. And has a vibrant community!

Inconvénients :

I like everything from this fantastic software

Excellent GIS tool

Commentaires : a positive experience is easy to use and the elements are available to the user

Avantages :

a quality software and it is also free for all users

Inconvénients :

which is available to all users for free and has a large number of tools to work with

Still the best Open Source GIS Software

Commentaires : IT has most features on it for GeoSpatial use along with added Geoprocessing tools and plugins, surprisingly found it a first choice for maybe handling with rasters imagery for simpler work. QGIS does everything I need for professional mapping & analysis.
The software is updated on time and regularly. easily connectable to other applications even including hardware GPS devices through plugins and has an easy integration with Excel Databases and supports most Excel Database formats. User Friendly GIS option.

Avantages :

Its pretty useful options if you want to convert from on format to another such as GDAL files having formats of Raster imagery such as converting grid files, image files to ASCII files etc including numerous other formats. Budget friendly option for Geospatial professionals plus easy to use tools for other professionals in the field of Environment or planning for their mapping work. Add on's are another useful feature, recently used and add on for adding surveys for data point collection of reviewing of data points, many developers are able to make add on plugins for QGIS.

Inconvénients :

There can arise issues such as lag or time taken for some geoprocessing tools, installation loading times, time taken for bulk tasks, in general using ArcGIS is more easier and better. Tool bar graphics can be out of date.

QGIS is my swiss army knife

Commentaires : I needed a program that could quickly extract topographic contours from a DSM tiff file, and do it at different resolutions. I've been using QGIS for this purpose for 2 years now.

Avantages :

The reason I sought out QGIS was to extract topographic contours from DSM tiff files. I have since found a dozen other uses for this very robust GIS program. Convert files, extract data, interpolate DSM files, analyze aerial data...the features are endless.

Inconvénients :

The learning curve can be a little steep at first, but there is an in depth wiki page that details every feature.

Very complete GIS software

Avantages :

This is a great open-source GIS software and is equipped with plenty of features and customization options for projecting and analyzing spatial data. Its interface with online maps from services like Google and Bing, which makes it easy to work with different basemaps. It's also a great alternative to ArcGIS, particularly for those who are looking for a free and open-source solution.

Inconvénients :

The software can be a bit tricky to navigate for those who are new to GIS or have limited experience with similar tools.

QGIS is great!

Commentaires : It's not that welcoming to new users, but once you get into it, it's really good. QGIS should enable you to get most of your GIS-related work done - and all of that for the price you can't beat.

Avantages :

Great GIS software. It is evolving constantly, it's free and it does the job well no matter if you just want to take a look at a shapefile or you want to deliver more complex projects - it's there and it works. On top of that you've got access to a number of plugins which should bring all the functionality you need.

Inconvénients :

There are a lot of software/libraries dependencies and backward compatibility is not always a guarantee for your projects. Even if it's not ideal it causes the extended use of older version of QGIS when working on a specific project for longer.

the best mapping software

Avantages :

this software is extremely important in the design of location maps, improving work efficiency. It is easy to use and allows the creation of maps in a short period of time. I use it in my work mainly to locate an area where a new company building is intended to be established in order to know the access spans to the site and the water availability .

Inconvénients :

I think that QGIS is simple to use and efficient in map making, but it is more difficult to install and use on computers with 32-bit capacity, thus making it difficult for many individuals to use it. in the company where i work most of those using computer with 32bit capability are unable to use QGIS due to this incompatibility.

Fully Featured Open Source GIS

Commentaires : Very positive experience with QGIS considering this is a free software. When compared to the paid options with similar features, there is little to complain about this product.

Avantages :

QGIS is open source with constant updates that continue to improve the software. Though some of the features may not be as robust as paid options, it is a great tool for anyone using GIS data regularly

Inconvénients :

The user interface is outdated and needs revamping. Some features are either difficult to find or sometimes buggy/not working.
