The friends of GISGeography.com have made an invaluable article in which they compare GQIS with ArcGIS, in nothing less than 27 topics.
It is clear that the life of both platforms is abysmal, considering that the origins of QGIS go back to 2002, just when it came out the last stable version of ArcView 3x ... that already included enough route.
Undoubtedly, we have never seen the maturity and obsession of the Geospatial theme as experienced by users of these two solutions. On the one hand ESRI supported by a private trajectory of a company with more than 40 years in the market, with the merit of being the means that came to popularize the spatial vision from a marketing and non-specialized public perspective; While QGIS is the most temporary initiative within the GIS approach, which managed to take advantage of the full potential of the OpenSource model, orchestrating a community that has a leadership not only of volunteering but of a high professional level.
In general, the comparison gives us interesting insights into aspects such as:
- 1. QGIS has a focus on being open to any kind of data.
- 2. Both seek to simplify the presentation layer before the end user, although with QGIS is not so simple if we consider that the wealth are the plugins.
- 3. The exploration of data between QGIS Browser and ArcCatalog are interesting, but they fall short as long as they depend on the existence of metadata. It is always difficult to search through the data.
- 4. Union of tables are fuoncionales in both, with slight advantages QGSIS.
- 5. Reproject and change coordinate system. Both are acceptable in handling native and on-the-fly projection, although the gain has been that QGIS has finally been able to read without error a projection of a .PRJ file.
- 6 The vast arsenal of online data from ArcGIS Online is a pending issue for QGIS that with the OpenLayers plugin allows many background layers but there is not much more.
- 7. The geoprocess is overcome by QGIS, but not because ArcMap does not have it, but because it depends on the type of license that is available, so you can use the different functionalities. Of course, among so many tools it is possible to get lost before trying them all, if we consider all the geoprocess routines that GRASS and SAGA have, of which we would like to have a single kit.
- Of course, this is a situation that no longer has to do with software capability but with the business model. Being a GPL license, everything is available.
- 8 The world of plugins is broad on both platforms. Although QGIS is very broad in this, where there are plugins for almost every thing, the difficult thing is what ArcGIS Marektplace makes easy, because there are solutions for everything with a focus of specialization easier to find. Of course, you have to pay.
- Although AGIS is a robust geoprocessing machine, it does not have the full range of specialized ESRI tools.
- 9 Raster data management is surpassed by ArcGIS. Although QGIS + GRASS offer battle, there is always something in which ArcGIS makes it easier; if not for added values, due to the difficulty of compatibility of plugins with respect to recent versions.
- 10 The ArcGIS Geostatistics tools can not be compared. They are not only functional, but educational.
- 11 With LiDAR data, one should think, because while some suggest that ArcGIS has gone overboard, others say that ESRI is thinking of imposing its own remote sensing format.
I suggest you give it a look and add it to your collection, since the article beyond wanting to defend a tool (which would be the most obvious), compares 27 similarities in aspects such as:
- Network Analysis
- Workflow Management (Model Builder)
- Final cartographic products
- Annotations and Labels
- Automation of continuous maps
- 3D Navigation
- Animated Maps
- Advanced Edition
- Topological cleaning
- Editing Tabular Data
- XY Coordinates and Coding
- Transformation of geometry types
- Support Documentation
In short, it is an arduous job that has led to this article. In many ways it surely requires more depth, which only knows who has used all the functionalities of ArcGIS and the guts of the QGIS plugins. However, something is satisfactory:
Never before have we seen an epic battle in GIS software like the one we are now seeing.
