====== GIS Editor Lesson 6: Viewing, Querying and Selecting Data ======

===== Viewing, Query, and Selecting Data =====

In this lesson we are going to introduce the “Select Features” Tab and how to help show relative data when needed.  Open your project from lesson five where we created label styles for the sales amount.  Our goal today is to show and highlight data that we determine.  

Begin by opening the project from Lesson 5.  First thing we want to do is view our data.  Under the home tab, find the “View Data” button.  After clicking this, the data from our “Data Join” layer is displayed.

In this screen you can sort your data to display certain types of information.  To do this you can click the filter button and add conditions such as greater than, equal to, etc.  If you want to sort your data you can click on the column headings, this switches the data from ascending to descending depending on what you choose.  Exit the “View Data” screen and select the “Selected Features” tab.


===== Selected Features Tab and Filtering Data =====
This tab allows you to manipulate your data to help adequately display it.  This tab offers a “Find/Query” option that allows us to specify a range or filtered set of data to be show on our map.

Now we will build our query, and make it display and highlight only those features that we want.  To do this begin by clicking the “Find/Query” button under the “Selected Features” tab.  This will display the “Find Features” dialog box.

To query our data we will add a condition.  Click the “Add Condition” button to display the “Query Builder” in the builder we will set our conditions and restraints.

For this lesson we want to only view those states who have sales greater than or equal to $100,000.00.  To do this we want to set the Column to “SALES_AMOU” Operation to “Greater than or equal to” and value=”100000”.  After all of the constraints have been filled click “OK” the map should now have the State that meet our criteria highlighted with yellow boundaries.  The next lesson will be over “Geoprocessing” where we can break up our sales data into sales territory.  Before you exit your application make sure to save your work.
