## Introduction to LandView 6

- A Viewer for EPA, U.S. Census Bureau, and U.S. Geological Survey Data and Maps

## What is LandView 6?

- A database management software & MARPLOT mapping software that displays:
- Census 2000 demographic data
- EPA regulated site locations
- US Geological Survey’s Geo  Names and Info System (GNIS)
- Census 2000 legal and statistical features
- TIGER/Line 2000 roads and hydrography

## What’s new in LandView 6?

- Entire Census 2000 Demographic Profile
- 108th Congressional district map layer
- Demo profiles for urban areas and urban clusters
- Expansion of the POP estimator to include demographic profile data
- Updated versions of the USGS and EPA data

## LandView consists of two software programs:

-  	The LandView 6 data viewer that provides a detailed data record for map objects and performs database queries.
-  	The MARPLOT map engine that displays individual map layers and results of LandView database queries.
- These programs work together to create an easy to use computer database retrieval and mapping system.

## Getting to know LandView Home

**Getting to know LandView Home**

- We will cover the following functions of LandView

- Learning these major functions provides a basis for discovering other LandView options on your own.

##      Getting to Know MARPLOT

**     ****Getting to Know MARPLOT**

- The MARPLOT Program will open.

## Marplot Navigational Tools

- The **Hand Tool** is used to make adjustments to your map display

- Clicking on the map with the  **Zoom-In** or **Zoom-Out **Tools will change the scale of the map by a factor of 2, and the click point becomes the center of the new display.

- The **Tape Measure Tool** measures distance and compass degrees, displayed at the bottom of the screen.

- In addition, clicking and dragging with the **Zoom-In Tool** opens a new map window that zooms to the dragged area.

## Use the Zoom-In Tool, click and drag around Arizona.

- A new window will open zoomed-in to the dragged area around Arizona.

## Use the Zoom-In Tool, click and drag around Maricopa County.

- The use of multiple layers shows too much detail at this level to be useful.
- However, we can adjust the layers  to our liking.

## List/Layer List

- In the Windows Menu Bar, open **List** and select **Layer List**.

- Three of the Headings,
- are self-explanatory.

- 	is an option that will show or hide layers automatically.

## Scroll down to “Census TIGER/Line 2000 Layers” and “EPA” and Hide everything except the major roads layer.

- Then, click **OK**

## The resulting map shows only county boundaries and roads. This process of Hiding and Showing Layers is used repeatedly to achieve the optimal look for your specific

- project.
- Please note that the MARPLOT mapping software is designed and best suited for creating

- large scale maps. A large scale map shows a great amount of detail for a small area

## Determine Census 2000 population and housing statisticswithin a one-mile radius of :	1789 West Jefferson Street	Phoenix, AZ 85007

- Determine Census 2000 population and housing statistics**w**ithin a one-mile radius of :	1789 West Jefferson Street	Phoenix, AZ 85007
