Analysis Tools

1. The 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. Whenever you need to solve a spatial or statistical problem, you should always look in the Analysis toolbox:
2. The analysis toolbox consists of groups of tools, they will be explained with an explanation of all the tools as follows:

Extract Toolset:

1. Datasets often contain databases
2. Geolocation contains more data than you need, these (extraction) tools allow you to select
3. Landmarks or what is meant by geographic phenomena of any kind in layers or tables based on
4. Query SQL expression or spatial extraction These geographical features or phenomena are stored in a new layer or layers or as a table.

• Geographical phenomena in a new layer or layers or in the form of a table:

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.

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.

Split

Splits an input with overlaying features to create a subset of output feature classes.

The Split Field parameter's unique values form the names of the output feature classes. These are saved in the target workspace.

Split By Attributes

Splits an input dataset by unique attributes.

Table Select

Selects table records matching a Structured Query Language (SQL) expression and writes them to an output table.

Overlay Toolset:

1. The Overlay Toolset contains tools for superimposing phenomena
2. geographic features or multiple features to combine, erase, modify, or update spatial features;
3. Resulting in a new layer, new information is created when overlapping a set of geographical phenomena

• With another set, there are six types of superpositions, all of which involve joining two existing sets of features into one set of layers to determine the spatial relationships between the input layers:

Erase

Creates a feature class by overlaying the Input Features with the polygons of the Erase Features. Only those portions of the input features falling outside the erase features outside boundaries are copied to the output feature class.

Identity

Computes a geometric intersection of the input features and identity features. The input features or portions thereof that overlap identity features will get the attributes of those identity features.

Intersect

Computes a geometric intersection of the input features. Features or portions of features which overlap in all layers and/or feature classes will be written to the output feature class.

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.

Symmetrical Difference

Features or portions of features in the input and update features that do not overlap will be written to the output feature class.

Union

Computes a geometric union of the input features. All features and their attributes will be written to the output feature class.

Update

Computes a geometric intersection of the Input Features and Update Features. The attributes and geometry of the input features are updated by the update features in the output feature class.

Proximity Toolset:

• The Proximity Toolset contains tools to determine the proximity of geographical phenomena within one or more categories of geographical phenomena or between two categories of features. These tools can determine the features that are closest to each other or calculate the distances between or around them:

Buffer

Creates buffer polygons around input features to a specified distance.

Create Thiessen Polygons

Creates Thiessen polygons from point features.

Each Thiessen polygon contains only a single point input feature. Any location within a Thiessen polygon is closer to its associated point than to any other point input feature.

Generate Near Table

Calculates distances and other proximity information between features in one or more feature class or layer. Unlike the Near tool, which modifies the input, Generate Near Table writes results to a new stand-alone table and supports finding more than one near feature.

Graphic Buffer

Creates buffer polygons around input features to a specified distance. A number of cartographic shapes are available for buffer ends (caps) and corners (joins) when the buffer is generated around the feature.

Multiple Ring Buffer

Creates multiple buffers at specified distances around the input features. These buffers can optionally be merged and dissolved using the buffer distance values to create non-overlapping buffers.

Near

Calculates distance and additional proximity information between the input features and the closest feature in another layer or feature class.

Point Distance

Determines the distances from input point features to all points in the near features within a specified search radius. 

Polygon Neighbors

Creates a table with statistics based on polygon contiguity (overlaps, coincident edges, or nodes).

Statistics Toolset:

The Statistics Toolset contains the spreadsheet as well as tools that calculate area, typography, interference, and adjacent features statistics:

Frequency

Reads a table and a set of fields and creates a new table containing unique field values and the number of occurrences of each unique field value.

Summary Statistics

Calculates summary statistics for field(s) in a table.

Tabulate Intersection

Computes the intersection between two feature classes and cross-tabulates the area, length, or count of the intersecting features.

In the same way, as described through this site. Watch the video first, then you can search for any tool by writing its name in the search, the language of the video is Arabic, but English subtitles and any language in the world are available. Good luck and God bless you.
