Viewing LandView® Data


When first opening a LandView database-either Census, EPA or USGS GNIS-records display in an unsorted format in Form view.

A Menu command, Records/Sort . . . , opens a dialogue box that will place records in sort order by an appropriate data Field. Often, this is sufficient to meaningfully examine a dataset.

A Roladex-type icon to the left of the LandView data screen, in an area known as the Status Area, allows scrolling through individual data records. A slide lever at the right of the icon permits rapid scrolling. Message displays in the Status Area tells whether All Records are available for viewing or whether the displayed records represent a Found Set. In either event, the number of records available for viewing is shown.

The data set in Form View can be viewed as a table by using the View as a List button at the top of the data screen.

In List View, at the left of each record is a small check box. Clicking here selects an individual record. When in List View, the View as a List button is replaced by View as a Form. Clicking on View as a Form returns the user to Form View with the selected record in display.

In LandView 6, the Census dataset has expanded dramatically from the 2000 Decennial Census data available for publication in LandView 5. In LandView 5, Census data was limited the demographic data known as Table DP-1 (a sub-set of data available in Census Summary File 1-SF1). In addition to the DP-1 table, LandView 6 adds the data in Tables DP-2 through DP-4-social, economic and housing data (a sub-set of the data in Census Sumary File 3). A set of tables DP-1 throught DP-4 summarized for the 50 States and the District of Columbia is known as the National Profile. A National Profile button at the top of each Census geography permits viewing the current dataset in relation to the National Profile.

The U.S. EPA database of regulated facilities show only limited data for each facility-facility name, locational information, assigned identifiers and the various EPA media programs under which each facility is regulated. However, with Internet access, much additional information is available for each facility. The Web Link button takes the user to EPA's EnviroFacts Warehouse to display a detailed regulation history for the displayed facility.

The USGS's Geographic Names Information System provides information on a broad database of geographic features, including feature names and feature types. The GNIS, however, is a relational database, and buttons provide additional descriptive and historical information, when available.

MARPLOT® Mapping Expands the Data in LandView

Each LandView record links to a geographic feature in MARPLOT. Identify one or more records in a LandView database and their geographic locations can display on a map. Similarly, MARPLOT map objects can be identified in a MARPLOT Search. Once identified, the information attributes of the Search Collection can be displayed in LandView.

However, this is only part of the LandView/MARPLOT story. Once map objects are identified either throught a LandView record search or a MARPLOT map search, their location vis-á-vis other map objects provides broad new information. What is the population living withing three miles of your home? Are there hazardous waste sites in proximity to your children's schools? What neighborhoods in your city, county or state meet a defined demographic profile?
