ADD XY DATA TOOLTakes a table containing XY data & Creates a layer from it. The table must alreadty contain two separate fields containing X & Y ( these X & Y fields must be Numeric data type ) coordinate data. The new layer will contain one point for each record in the table.

• Exercise : - Provided RO details along with the Coordinates. Plot these RO locations

Open Arcmap Go to Tools & click Add XY data tool. Add XY window appears

FILE HAVING THE COORDINATES

SELECT THE FIELDS HAVING X & Y COORDINATE

DEFINE PROJECTION OF THE COORDINATE AVAILABLE IN THE FILE

BUFFERING A distance analysis tool for points, lines, and areas Create new polygon representing specified distance Answer questions based on proximity

Buffer 50 meters Buffer by attribute values

Buffer 100 meters, do not dissolve interior borders

Go to Customize In Customize windows Commands Tab

1. Choose the features 2. Choose the distances

3. Choose the output type & output file 4. Display output layer or graphic

• Exercise : - Provided a Road & Building Layer. All the roads are going to be widened by the distance mentioned in N_WIDTH field in the Road shape file. Identify the number of Buildings affected.

TOPOLOGY

Topologies maintain high-quality spatial data by ensuring that your features conform to simple rules. When you set up a geodatabase with a topology, you specify which feature classes participate in the topology and define rules that control when and how features can share geometry. For example, in a geodatabase of states and coastlines, you might have a rule stating that polygons cannot overlap each other and another rule that the coastline must coincide with the boundaries of the states. These rules would help you ensure, when updating the state boundaries to match the coastline, that you don't inadvertently create places where the states overlap or where a state's coastal edge doesn't match the shape of the coastline.

For Using this option all the layers must be in Featureclasses & should be inside a dataset.

This option is not available in ARCVIEW license.

Right click on the dataset having the layers for which the topology is to be checked.

Go to New topology option.

TOPOLOGY – DEFINE RULES

ENTER TOPOLOGY NAME & DEFINE THE TOLERENCE ( GENERALLY KEEP THE TOLERENCE AS THE DEFAULT VALUE )

SELECT THE LAYERS FOR WHICH THE TOPOLOGY IS TO BE CHECKED

ASSIGN RANKS TO THE LAYERS ( FOR OUR PURPOSE DON’T CHANGE THE RANK, KEEP THE DEFAULT VALUES )

CLICK ON THE ADD RULE BUTTON TO ADD THE TOPOLOGICAL RULES

ONCE THE ADD RULE BUTTON IS CLICKED THE WINDOW SHOWN ABOVE APPEARS & THE USER CAN DEFINE THEIR RULES ON THE LAYERS. ONCE RULES ARE DEFINED CLICK NEXT & FINISH BUTTON.

THE USER WILL RECEIVE A MESSAGE AS SHOWN ABOVE. CLICK ON YES BUTTON

TOPOLOGY – VIEWING THE TOPOLOGICAL ERRORS

ONCE THE PROCESS IS COMPLETE, A TOPOLOGY LAYER IS CREATED INSIDE THE DATASET.

GEOMETRIC NETWORK

A geometric network is a connectivity relationship between a collection of feature classes in a feature dataset. Each feature has a role in the geometric network of either an edge or a junction. Multiple feature classes may have the same role in a single geometric network.

Create in ArcCatalog Edit in ArcMap Analyze in ArcMap

Up and downstream tracing Find connected features Find the most efficient path

For Building Geometric Network the Layer must be featureclass inside a Dataset

This option is not available in ARCVIEW license.

Right click on the dataset having the layers for which GEOMETRIC Network is to be created.

Go to New Geometric Network option.
