Select analysis methods and tools to perform analysis checks and optimize the results.
Step 1: Formulate the problem.
This step seems easy, because you are usually assigned a project to perform specific information. obtain.Some items contain answers to various questions arising from the overall question.The wording of the question will help determine which GIS tools and techniques will be used for analysis. Where are the sanitary facilities? What is the population distribution in the study? Do the most densely populated areas have the most convenient facilities?
Step 2: Check and prepare the data.
This step may take longer. If you don’t have all the data needed to analyze the project, you need to collect it. The ArcGIS World Atlas is an excellent source of high-quality spatial data.For each data set, check the geography, attributes, and metadata of the features to determine whether the data is useful for your analysis and what kind of preparation. Is the geometry of the object suitable (ie point, line, polygon)?
For analysis? Do they have the attributes you need? Does the data have access or use restrictions? First, you need to determine the data format to be used. The project data does not have to be in the same format, but it can make your work easier. It is important to ensure that the analysis tools you need to use accept your data format. Also, consider disseminating the data generated by the analysis. Organizing data in project folders can simplify your analysis tasks (you can specify a standard input workspace for all geoprocessing tools).
For projects, you need to create a folder to organize the shapefile.If you want to use feature classes stored in different geodatabases, you can copy or import them into a single geodatabase in your project.
Step 3: Selecting tools and analysis methods
In order to select the appropriate tools and methods for your analysis project, please consider the following: The questions asked in step 1, and record the methods and tools that can be answered in each case.
Step 4: Perform analysis
After the process is established in step 3, in this step, you only need to follow the diagrams and perform each task in turn. You can create a model in ModelBuilder to automate the process. The model also allows you to quickly change the parameters, and then run the model again to check different scenarios.
The fifth step :
Check and refine the results.
This is a five-step process to complete a GIS analysis project using ArcMap. The same analysis can be easily done in ArcGIS Pro).
