APPEND - Geo-Processing

APPEND

Combines two or more adjacent layers into a single layer 

 In simple terms combine two or more layers together in to a single layer.

Now we are going to Append two provinces in Sri Lanka,

Steps

1. Open ArcMap and add data you are going to use for this project,

2. Then you can go to "search" and find "Append" or ArcTool Box Window> Data Management Tool > General> Append,

 

3. Now we are going to append "Central" province with "North-Central" province,

4. Now you can see "North-Central" layer have appended the "Central1" layer,

GEOPROCESSING

GEOPROCESSING

Geoprocessing allows you to analyze and combine layers in different  ways based on the spatial relationships among features. 

  

 Following are the operations in Geoprocessing, 

• Dissolve - Aggregates features in a single layer that have the same attribute values.
• Append - Combines two or more adjacent layers into a single layer.
• Clip - Reduces the spatial extent of one layer based on the extent of another.
• Intersect - Finds those features falling within the spatial extent common to two layers
• Union - Combines two polygon layers.
