This post almost didn’t happen. For over seven years I’ve been comparing GIS software in the hope that someone would be reading and take it upon themselves to fix a few of the issues that we all run into on a daily basis. With the new releases someone told me something, and it almost stopped it all from happening …

“Esri is the Apple Inc., and QGIS is the Google.”

As painful as it is to hear, it’s true. Even though I’ve been a hardcore user of QGIS for over five years, I find myself falling back into using the ArcMap tools just to save myself rummaging through lists of plugins, and I especially like that I can just drag and drop my data into the data frame and it just works.

As powerful as ArcMap/Arcscene/ArcGIS Pro/ArcGlobe/ArcGIS Explorer/ArcServer/Arc*add your own term here* is, it feels old and a little clunky, like using Windows XP. For a decade it has had the same comfy interface, the same basic functions, and the same symbology. This is by no means a bad thing, but the cartographic capabilities of QGIS are far superior, and let’s not mention the true 64bit processing.

This year, there is a new contender from Esri that I feel I need to discuss, ArcGIS Pro 1.2. Although it is in beta, it is already proving itself a worthy successor to ArcMap. Unfortunately, until it is out of beta, I won’t be testing it as I feel it is unfair to compare an unfinished software.

Before we get to the crux of things, I’d just like to add that there have been no major interface changes to either software, and I am GIS neutral. I just want a GIS that works and is reliable; I have no bias as to one or the other.

What is new in QGIS 2.14?

The most talked-about is the inclusion of a 2.5D renderer (covered in earlier blogs), but what you may not have noticed are the subtle changes, changes to the processing, caching, labeling, and legend. Here is a full list that links to the QGIS changelog

What’s new in ArcMap 10.4?

There are quite a few new raster types available for the software, some of which I have to admit that I had never heard of, but it’s interesting to see that you can now export topology errors in the ArcMap Basic license. For those wondering why I haven’t listed all the changes, please remember that this is a comparison of the basic GIS software.

Data Management toolbox

Editing toolbox New tools Transform Features

Multidimension toolbox New tools Make OPeNDAP Raster Layer

Python and ArcPy ArcGIS 10.4 has been upgraded to include Python 2.7.10. Additional third-party libraries including SciPy, pandas, Sympy, and nose have been included, and existing third-party libraries including NumPy and matplotlib have been upgraded to more current releases. The GetPackageInfo function has been added to return a dictionary about packages.

Editing The topology edit tool now supports additional commands and keyboard shortcuts for selecting and moving nodes and edges. Press the N key to select topology nodes.

key to select topology nodes. Press the E key to select topology edges.

key to select topology edges. Move and Move To commands are now available on the topology edit tool context menu. Parcel editing Parcel merge The parcel Merge dialog box now has additional options for managing parent parcels. Parent parcels can be deleted, flagged as historic, or remain as current, active parcels. Parcel division When dividing parcels into equal areas, the number of parts on the Parcel Division dialog box can be set to 1. Set the number of equal area parts to 1 when a deed calls for a specific area to be divided from the parcel, leaving a remainder parcel. Mean points Performance improvements have been made to the Mean Points tool. Furthermore, the tool now always stays active and can be used repeatedly without the need to specify a tolerance. Least-squares adjustment Collinear line sequences in the same plan are straightened during adjustment postprocessing if they lie within the specified Straighten Collinear Line Sequences tolerances. These tolerances are available on the Adjust Coordinates dialog box. Geodata Geodatabases and databases A new advanced option—All records for Tables—has been added to the Create Replica wizard. Checking this option allows you to designate the inclusion of all data from all tables in your replica. In earlier releases, you had to set the option to include data for each table individually.

wizard. Checking this option allows you to designate the inclusion of all data from all tables in your replica. In earlier releases, you had to set the option to include data for each table individually. Beginning with ArcGIS 10.4, you must set an additional option (Return Output Parameters As ResultSet) when you configure the ODBC driver to connect to Teradata.

ArcGIS now supports connections to Dameng databases. You can connect to view and analyze data in ArcMap. You can also publish map and feature services to ArcGIS for Server .

. If you use SAP HANA 1.0 SPS10, you can now use ArcGIS to load data that contains z and m values and you can view and analyze existing data that contains z and m values. LAS Dataset There is a new scrollable LAS point profile view. Using the mouse/keyboard keys the area-of-interest profile window will move or rotate and update immediately in the profile window.

Location of the cursor in point profile window is displayed in ArcMap inside the profile area-of-interest.

Elevation is now displayed and updated when moving cursor around in point profile window Raster There have been five improvements for raster types. The SPOT-7 raster type is now supported.

The UAV/UAS raster type is now supported.

The WorldView-3 raster type now supports the SWIR bands.

Support netCDF and HDF data stored as irregularly spaced arrays is now supported.

There have also been improvements within Chinese raster types. There are several improvements with raster geoprocessing. The Segmentation and Classification toolset has a new Train Random Trees Classifier tool. New parameters were added to the Train ISO Cluster Classifier tool.

The Add Rasters To Mosaic Dataset tool supports two new parameters: Auxiliary input and Estimate mosaic dataset statistics .

and . The Copy Raster tool supports two new parameters: Format and Apply transformation .

and . The Compute Tie Points and Compute Control Points tools both have two new parameters: Point Distribution and Point Density .

and . The Make Mosaic Layer tool supports the Processing template.

The Generate Tile Cache Tiling Scheme tool now supports LERC compression.

There are two new geoprocessing environment settings added: LERC compression and parallel processing server . The Georeferencing toolbar now has three new first-order transformations available: Only rotation and shift, Only shift and scale, Only rotation and scale.

Testing

A lot has changed since I last ran this; I no longer have the 8 core 32GB RAM “beast” anymore for starters. I expect that times will be changed, but by how much?

For those who want the spec of the machine I am using:

Although it is more home computer spec, I am reliably told that this is should be more than adequate for running ArcMap and QGIS.

1. Load Time As this is a comparison of the two new updates. Rather that witter on about my personal views, I thought it better to provide some test results. To make the test equal, the method I use was to start up the software being tested, leave it for 10 minutes (to ensure all elements have loaded), and the add ALL 2010 AIS from a folder in the root – C:\GIS\. If you wish to test the data yourself, it can be downloaded from here. The timer was started from the moment that the data is added to the data frame (through the add data button). The timer is stopped when all data has finished loading, indicated in ArcGIS by the globe in the bottom right not spinning and in QGIS by watching the windows processes and seeing when the CPU demand dropped to zero again. For those who wish to go further down the rabbit hole, I categorized the data for both QGIS and ArcGIS and saved the styles. The AIS was categorized using standard deviation (n0) with eight categories. Data was loaded directly from the qml/lyr. The time given is the average of the five runs which were made. Results: ArcGIS 10.2 = 27.27 seconds ArcGIS 10.3 = 38.5 seconds ArcGIS 10.4 = 24.04 seconds QGIS 2.6 = 9.103 seconds QGIS 2.8 = 8.201 seconds QGIS 2.14 = 5.08 seconds On average QGIS was 20 seconds faster to load the data; furthermore, there was a slight speed increase for QGIS from 2.8 to the newer 2.14 2. Testing – Analysis What use is your software if you spend your days waiting for it to finish a process? The amount of time I must have lost due to running processes is immense, so what if I could save some time? Because of this, I ran a viewshed test. I put a single point down. Then, using standard settings (and OS Terrain50), I ran a viewshed (ensuring the output raster resolutions are identical). ArcGIS 10.2 = 42 minutes ArcGIS 10.3 = 4 failed attempts & gave up* ArcGIS 10.4 = 12m 55s QGIS 2.6 = 58 minutes QGIS 2.8 = 1hr 16min QGIS 2.14 = 26.86s It looks like either this machine is far superior to the old desktop OR both software has made significant improvements in its calculation algorithms. To confirm, both outputs were identical and can be obtained through the link at the end of the article. 5. Testing – Map Export *To eradicate any issues with the data input or user error, the ArcGIS 10.2 map was saved and then opened in 10.3; the exact same parameters were used with no success. I seem to lose days exporting PDF files from GIS, so for me, this test is one of the most relevant so that I can compare the amount of time consumed by the simple “PDF Export.” For this test, the same EFH shapefiles used previously were loaded, no styles applied, then the bathymetric contours (also from the Marine Cadastre website) and the Esri world countries shapefile. I then opened the layout/composer and set the orientation to landscape and the size to A3. Scale was set to 1:50000,000 then centered on the EFH data. Once loaded and left to settle of 10mins, I set the PDF export to 500dpi and then made sure that both the QGIS and ArcGIS settings were the same* (no layers, no georeferencing etc). This is the average times for five runs. The results were as follows: ArcGIS 10.2 = 3mins 18s – File size 795MB ArcGIS 10.3 = 3mins 30s – File size 903MB ArcGIS 10.4 = 7.04s – File size 1.9MB QGIS 2.6 = 37.4s – File size 72MB QGIS 2.8 = 35.5s – File size 69MB QGIS 2.14 = 10.3s – File size 18.16MB *Just to be clear, ArcGIS and QGIS were run separately 6. Stability This is a new category, as a few comments I have had asked how many crashes I have had whilst testing. I am please to say on this occasion NONE. 6. Niggles As I worked through, I must say that both software were pretty much as expected; nothing has really changed. The ONLY thing I would pick up on is that QGIS needs to add layers to their browser. When looking for data, QML and SLD are not visible in their relative folders.
