The text below touches briefly on these automation options, in order from requiring the least coding skill to the most. These options differ in the amount of skill required to produce the automated solution and in the range of scenarios that each can address. The ArcGIS platform provides several ways for users to automate their geoprocessing tasks. In contrast, once an automated task is configured, a computer can be trusted to perform the same sequence of steps every time for a potentially endless number of cycles. The chance multiplies with the number and complexity of the steps in your analysis, as well as the fatigue incurred by repeating the task many times.

Any time you perform a manual task on a computer, there is a chance for error. A computer can open and execute tools in sequence much faster than you can accomplish the same task by pointing and clicking. Once you automate a process, you don't have to put in as much effort remembering which tools to use or the proper sequence in which they should be run. There are several major benefits to automating tasks like this: Because this scenario involves running the same sequence of tools for several areas, it is one that lends itself well to automation. However, let’s suppose you’re responsible for carrying out the same analysis for several areas around the country. If this selection process were limited to a small area, it would probably make sense to perform the work manually. You might use one tool to select land parcels along a major thoroughfare, another tool to select parcels no smaller than 0.25 acres, and other tools for other selection criteria. Suppose you’re responsible for selecting sites for a chain restaurant. You pick the tools you need and run them in the proper order to make your finished product. ArcGIS uses a toolbox metaphor to organize its suite of tools. Successful GIS analysis requires selecting the most appropriate tools to operate on your data.

In the ArcGIS software used in this course, these operations are known as geoprocessing and they are performed using tools. This includes clipping, reprojecting, buffering, merging, mosaicking, extracting subsets of the data, and hundreds of other operations. GIS analysts perform all kinds of operations on data to make it useful for solving a focused problem. A geographic information system (GIS) can manipulate and analyze spatial datasets with the purpose of solving geographic problems.
