Description

Arc Map is basically designed for GIS, but we can also use it for remote sensing purpose. There are mainly two types of data that are Raster data (images) and Vector data (shape layer) . In Arc map we can process both datasets. In Arc map the “Table of Content” shows the layer information within it and the “Catalog” bar keeps all the functions with the dataset. In the video we perform the following analysis.

Add Data

The very basic thing to perform any analysis we need to add the data can be vector or raster. We can add the data from the “Add data” tool or we can add the data from the catalog view. We can use both, but the catalog view made not only to add the data but also to modify, analysis and various other purpose.

Rename the Layer

From the catalog view we can directly rename the layer by right clicking and after that remove the layer from the view bar and again open it. We can also Copy a layer from the catalog and also paste the layer into another folder directly. The most important note, if we delete something from the catalog it will delete the thing permanently, so always keep in mind while deleting an object in catalog.

Knowing the Information

The “identify” tool is made to give all information of the existing layer (both vector and raster) in the view bar. If we want to know any information of the data from the tool, we can easily get to know the basic information and also the projection information which data contains within it. For vector data we can also know the information by opening up the “Attribute Table” . We can see the existing information and also add information as per our necessity.

Labeling the Data

If a vector data contains information in it, we can display the information on the data set and also can modify as per our necessity.

Layout of a Data

Preparing a map is simply known as Layout. After performing all the analysis part, we prepare a map and then give it a layout view to read the map easily. The layout purpose is all about to express the information content to a general person who can easily understand it.

Export a Map

After preparing the layout of the data it is generally exported in our needed format for a non-GIS person to a readable format. We can also say it the final product of the mapping purpose.
