CHAPTER 3

Objective:

 To convert the coverage into shapefle

 To examine the data structure.

 To create a geodatabase and import shapefle in to it.

 To coverage with built-in regions and route subclass.

 To convert data into a digital elevation model (TIN).

Task 1: Examine the data file structure f cvera!e and sha"efile

#ummar$

For task 1, it shows the data layers such as label, polygon, arc and tic. It also ask to convert the

coverage into a shapefile and examine the shapefile’s data structure.

Task &: Create !edatabase' feature dataset and feature class

#ummar$

For task #, it ask to create a file geodatabase and a feature dataset. $eodatabase is created and

name as Task2.gdb and for new feature dataset, we named it as  Area_1 and the pro%ected

coordinate system is &!', ()* 1+#, -( 11. !his coordinate system is shared by all feature

class in  Area_1.  (ext, import the shapefile intointo the feature dataset as feature classes and

examine their data file structure. ) standalone feature class and feature class in a feature dataset

cannot use the same name and the name must be uni/ue.

Task 3: Cnvert a sha"efile t a "ersnal !edatabase feature class

#ummar$

In task 0, the data will be update the area and perimeters value of shapefile by converting it into a

feature class in a personal geodatabase. !he personal geodatabase is rename as task3.mdb.

Task (: Examine "l$lines )ith measures

#ummar$

In task , we need to identify the route location or we need to examine the polyline shapefile.

2hen we click the route, the coordinate will appear.

For task 3, it ask to view the regions and route subclasses that reside in hydrography coverage.

 (ew data frame is created and named as 4nhd15 and 4nhd#5 then add shapefile data into the

frame. !he layer can be converted in nhd which is known as coverage layer into a shapefile or 

geodatabase feature class.
