ESRI software naming is confusing, however logical. I did think about how their ArcGIS Desktop products could be name more appropriately never know who is reading your blog , and I think a good solution would be to offer all licensing levels as a network and as a standalone edition. This would introduce one new product, ArcInfo Standalone. I am sure there is a market for an ArcInfo Standalone!

Have you ever tried to assemble furniture without the instruction manual? Practically impossible, right? When you run tools in the ArcGIS Geostatistics Toolbox, the instructions and output explanations are so clear that a child could understand the results.
You know if your data is auto-correlated or not. In QGIS, you need a good understanding of the tool beforehand. The exploratory regression tools in ArcGIS are well-made because the outputs allow users to connect statistics with their data. This saves time for analysts. The columns are your statistics types average, minimum, variance, etc. Rows are categorical fields such as place names or watersheds. Add a value field and push calculate.
Voila, your pivot table is generated. When you can make difficult concepts straight-forward, you become a winner in my book. And ArcGIS is best at teaching geostatistics. Silently, satellites collect data of our planet with active and passive remote sensing. Satellites like Sentinel 2 and Landsat 8 are the exciting ones making data more ubiquitous to GIS analysts.
Some of these are like hand tools , like a chisel. Others are like power tools , like an electric drill. When ArcGIS 10 added the image analysis toolbar, it instantly provided remote sensing analysts with the necessary tools to create samples and perform unsupervised and supervised classification. Pansharpen, perform NDVI , orthorectify and interactively change the brightness, contrast and transparency.
It still gets the job done. A Guide to Earth Observation. In ArcGIS, flick on the network analyst switch. Add your data to a network data set. Building a clean topological road dataset is the challenge.
When you run redundant tasks as a scheduled model, you can sit at home in your bathrobe all day long and still get work done. You string together sets of tools in Model Builder to automate processes. Drop tools in your Model Builder Diagram and connect them. ArcGIS scripting is almost all run through the Arcpy module. Automate everything. You will also be using a bunch of other modules as needed for different projects. It can be difficult to figure out what to use and where it all is.
But QGIS is a viable option to create cartographic masterpieces. It acts almost like another application. ArcGIS layout view is how to set up map templates and export map products. The ArcGIS layout view is practical. It has tools to pinpoint your labels, set up mapbooks, and link data frames with easy extent rectangles.
ArcGIS is loaded with stunning symbology on startup. We like the symbology by discipline transportation, real estate, soils, weather, etc. The existing symbology in ArcMap is beautiful, useful and plentiful.
QGIS misses the beat on pre-existing choices. Life would be easier in QGIS if it came equipped with symbology like railways and hatched polygons. Keep in mind: you can download and load them to your symbology palette. It has more blending options than a symbology bakery: lighten, screen, dodge, addition, darken, multiply, burn, overlay, soft light, hard light, and difference. You can create simple gradients with two or multiple colors.
Add the different types-linear, radial, conical. You no longer have to write an RGB code again. QGIS has some really advanced symbology. ArcGIS is practical and puts symbols in the hands of the cartographer. Both are winners in my books. Gain full control of exactly how and where you want to label features.
Set label location and scale dependency. Curved and parallel labeling is easy in ArcGIS. The drawing toolbar is how to control annotation groups in ArcGIS. Make a separate toolbar for annotations. But with a little practice, you can control which annotation group labels belong to. It is your complete arsenal for automated map production. The index layer is used to create each page. The Cartographer Toolbox is how to create strip maps.
If your map spans multiple projections, use the Calculate UTM zone tool. For each geometry in the coverage layer, a new output will be generated. Fields associated with this geometry can be used within text labels. A page will be generated for each feature. ArcGlobe and ArcScene are stand-alone programs using the 3D analyst extension. These applications give you a chance like no other to enter a world in 3D.
ArcScene is for small study area scenes. Extrude objects with amazing vertical exaggeration. Z-factor is your friend. ArcGlobe is for data that spans the whole globe. Make your data come to life. Perform wicked fly-throughs. QGIS lacks decent 3D support. The Qgis2threejs plugin can catapult you in three dimensions. The Qgis2threejs plugin exports terrain data, map canvas image and vector data to your web browser.
Web maps are on the uptrend. The news industry, governments, and businesses are using web maps because they tell a story.
Web mapping is easy in ArcGIS. A cool trend are ArcGIS story maps because everyone has a story to tell. With ArcGIS, you can harness the power of maps to tell yours. Watch polar ice caps melt over time. Display global time-aware weather patterns. ArcGIS makes it an easy process to go from static to dynamic with its animation toolbar. When you have a time-enabled field, scroll the time slider left-to-right. Watch your data change over time. A little preparation is necessary but nothing too painful.
Export as an AVI and impress your boss. Using time controls, you animate vector features based on time attributes. There is also an experimental raster layer support and interpolation between point geometries.
You can create animations directly in the map window and export image series. Social scientists often construct thematic maps because they show a particular theme connected with a specific geographic area. For thematic mapping in QGIS, cartographers have a range of options. For example, there are graduated colors, proportional symbols and dot density. One of the unique tools in QGIS is the heatmap display.
Take a point data set and instantly create a heat map without raster conversion. Adjust the radius, color ramp, transparency, and blending mode. In the end, the heat map renderer delivers live dynamic heatmaps for point layers. Dot density maps and stacked charts are unique qualities to ArcMap. Not the legend you see on a map, of course.
But not all editing tools are created equal. You right-click to end a sketch in QGIS. You double-click to end a sketch in ArcGIS. QGIS offers a range of tools for editing like reshaping, splitting and tracing with the AutoTrace plugin.
Delete rings from features and create donuts with simplicity. You snap features using snapping options. One of the bright features is rolling back edits in QGIS.
This can only be done in the vertex sketch properties in ArcMap. Every vertex can be moved and removed. ArcGIS has more options for advanced editing. You create features by setting up feature templates. The trace tool in ArcMap was sent from heaven. This is a genius toolbar. Inspect your topology with over 30 rules with the error inspector. Resolve topology issues with automatic or manual fixes.
Once your data is in a geodatabase, you can start creating topology rules. You validate your geometry based on these rules, but how do you fix it? They both provide similar functionality. When you create a shapefile in QGIS, you are prompted to set up your fields text, whole, decimal number, or date. You probably thought in ArcGIS, you have to create a new field and copy the contents over to the new field.
But the Alter Field Data Management can accomplish this. In geodatabases , users can set up subtypes, domains and default data entry. When users start entering attribute information, they can select from drop-down lists. This is how to steer clear from invalid entries when GIS analysts start going rogue.
Selection by location has been improved with its interactive selection tool. When records are selected, they can be filtered even more so selected from, added to, removed from.
The field calculator supports Python and VB to execute code. What is geocoding? Geocoding is the process of giving XY values to street addresses. This is a paid service requiring credits to use. ArcGIS Desktop has its own way to geocode using your own data. To do this, you create an address locator. Find addresses using the Geocoding Toolbar. Type the location and add a labeled point. If you want to avoid credit systems of any form, then you have two options in QGIS.
Both are good options. This plugin takes a spreadsheet CSV containing multiple addresses and adds them to the map canvas as points.
The GeoCode plugin requires an address as input. Type an address.
