Create Feature Dataset in ArcGIS

A feature dataset is a collection of related feature classes that share a common coordinate system. Feature datasets are used to spatially or thematically integrate related feature classes. Their primary purpose is for organizing related feature classes into a common dataset for building a topology, a network dataset, a terrain dataset, or a geometric network.


Step 1,

Right click on the Geodatabase --- New --- Feature Dataset

Step 2 -

Give a name as you wish --- Next

Step 3, 

Assign a coordinate system to feature dataset,

Step 4,

after assigning the coordinate system just press next till its finish... Done

Create GeoDatabase in ArcGIS

Create GeoDatabase in ArcGIS

The geodatabase is the common data storage and management framework for ArcGIS. It combines "geo" (spatial data) with "database" (data repository) to create a central data repository for spatial data storage and management.

Three types of Geo Databases available with ArcGIS

1. Enterprise GeoDatabase
2. File  GeoDatabase
3. Personal GeoDatabase

following are the steps to create Personal GeoDatabase..

Step 1,

select location to create GeoDatabase

Step 2,

Right click on the location --- New --- Personal  GeoDatabase

Step 3,

Give a name as you wish and the format will be .mdb Done..

Creating Maps in ArcGIS

Creating Maps in ArcGIS

Creating maps using ArcGIS including extended indicator, legend, etc...

Step 1,

Add shape file of a area you need

 Select layout view,

 Select "Insert" then select options you need,

How to select "Title",

Select "Dynamic Text" ,

Select "Neatline" to add boraders, background colors etc...

How to add "Legend" to your map

 Add "North Arrow"

 Add "Extended Indicator" to you map

Export Maps 

Add Hyperlinks

Hyperlinks allow you to access documents or web pages related to features.

Step 1, 

In the Attribute table provide some URLs, Scripts, Documents you need..

Step 2,

Right click on the layer -- Properties -- Display -- Hyperlinks -- Tick on the "Support Hyperlinks using fields ". the select either Document, URL or Script.

If you select document in your field you have to give the path to you document ex - F:\Blog Image\Hyperlink

If you select URL then you have to give the URL's

 If you choose to use a script, use the Edit button to write your script using JScript or VBScript.

Step 3,

Select the field you have given the URL's, Documents paths....

 Step 4,

Then select Hyperlink Button,

 Step 5,

You can see the hyperlinks, and just click on the desired place, it will direct you to given URL or Documents...

Spatial Selection

Select by Location in ArcGIS

In ArcGIS we can use Spatial selection to select features which are related to another layer, as a example in the province layer what are the cities effect by the highway road,  try following example,

Step 1,

Add city or province layer you want to select,

Step 2, 

Add another layer you need to intercept, (here I'm using a road layer)

Step 3,

Then in the tool bar select "Selection" tool, and select "Select by Location", 

Step 4,

Then in "Selection Method" select "Select Features From" option, then in the "Target Layer(s)" you have to select layer you need to get the out put, for this example I have selected "Anuradhapura_gnd", then for the "Source Layer" you have to select next layer using for this operation, 

Step 5, 

finally in the "Spatial Selection Method" we have to select " Target Layer(s) features Intersect the Source Layers features" (normally it is the first option to be select) then "apply" and "ok"

Step 6, 

You can see now it has been selected intersect features,  

Step 7,

If you open the attribute table you can check the selected data, 

Step 8,
If you need to export selected data as a shape file you can follow below steps,

Thematic Mapping / Symbology

                                                   

                                     Thematic Mapping

In previous post we have given different colors to the different polygons, here we are doing something like same but here we are doing  analytic process, so this maps can be use for analytic tasks, 

Step 1 , 

  

Just add a your shape file in to layer

Step 2,

Then "right click" on the layer and go to properties then select "Symbology" tab.

Step 3,

Then select "Graduated Colors" under "Quantities".

Step 4, 

After that from "Value" select field you need, I have select "Male" filed for this task.

Step 5,

from "Classification" we can select how many breaks we need (number of range), 

Step 6, 

Then from the "Color Ramp" select color range you required. 

Step 7,

Then you can see the result by just click on "Apply" and "ok". Left hand side you can see the ranges and the colors as we given.
