WSU - Analysis



The Esri ArcMap Analysis toolbox contains a powerful set of tools that perform the most fundamental GIS operations. With the tools in this toolbox, you can perform overlays, create buffers, calculate statistics, perform proximity analysis, and much more. Esri breaks the Analysis toolbox into five toolsets: Extract, Overlay, Pairwise Overlay, Proximity, and Statistics. The Analysis toolbox contains many of the first tools/operations one will learn when beginning in GIS. Below provides an overview of many of the most used tools from the Analysis toolbox.

     Spatial Join
     Attribute Join

Analysis - Spatial Join
Joins attributes from one feature to another based on the spatial relationship. The target features and the joined attributes from the join features are written to the output feature class. 
SEidwV2Pclean spatially joined with SoutheastStatesWGS.

AnalysisAttribute Join
Joins a table of data to a layer based on the value of a field that can be found in both tables. The name of the field does not have to be the same, but the data type has to be the same; you join numbers to numbers, strings to strings, and so on.
Ran the Attribute Join process to join COStores to the table generated with Near Table, chose the two TestStores that fell within the 5 mile buffer. Join was based on ObjectID = In_FID and keeping only matching records.

Analysis - Union
Computes a geometric union of the input features. All features and their attributes will be written to the output feature class. 
Joined a created Canada/Mexico shapefile with StatesWGS1984 shapefile (created so they have the same projection - required) to have a new North America shapefile that is US States + Canada + Mexico.

Analysis - Merge
Combines multiple input datasets of the same data type into a single, new output dataset. This tool can combine point, line, or polygon feature classes or tables. Use the Append tool to combine input datasets with an existing dataset.

Analysis - Dissolve
Aggregates features based on specified attributes.
Dissolve states shapefile into a region specific shapefile.

Analysis - Clip
Extracts input features that overlay the clip features. Use this tool to cut out a piece of one feature class using one or more of the features in another feature class as a cookie cutter. This is particularly useful for creating a new feature class—also referred to as study area or area of interest (AOI)—that contains a geographic subset of the features in another, larger feature class. 
Clip fishnet points to Atlanta City boundary from ATLmetroarea.

Analysis - Buffer
Creates buffer polygons around input features to a specified distance. important feature of the Buffer tool is the Method parameter which determines how buffers are constructed. There are two basic methods for constructing buffers: Euclidean and geodesic. 
Did a 5 mile buffer around the RetailStores with the buffer tool.

Analysis - Select
Extracts features from an input feature class or input feature layer, typically using a select or Structured Query Language (SQL) expression and stores them in an output feature class. 
Select ATLmetro (stores) by city = Atlanta.

Analysis - Create Fishnet
Creates a fishnet of rectangular cells. The output can be polyline or polygon features.
Created sampling points over Atlanta City limits.

Analysis - Create shapefile
Create new feature by drawing polygons for new shapefile (ATL metro area and ATL city).
