Browsing

NJGIN Explorer is your tool for searching and browsing the contents of a metadata service—a central repository for metadata. Search by geographic extent, content type, content theme or keyword, or browse through all of the available metadata documents. Use the metadata you find to decide whether the data it describes fits your needs. It's that simple!

Click the Browse tab to browse through an alphabetical list of datasets by content theme. Click the Search tab to search for data based on specific criteria. Scroll through the browse or search results in the right panel.

  BROWSING
 

Metadata cataloged on NJGIN can be browsed by content theme. Themes appear in the left panel of the browse window. Click on a theme and metadata records cataloged by that content theme will appear in the right panel of the window.

When you click a content theme, a list of records appears in the right panel. Each record summary includes the name of the publisher and the content title. Often the record summary also includes the coverage area and map scale of the dataset. In many cases, a thumbnail image of the data also appears.

Each record is followed by at least one of the following buttons: View Details, View Map, Add to ArcMap, if the session is from arcmap. See Viewing Content for more information about these tools.

  SEARCHING
 

Many searches begin with defining the search area. There are two ways to define the search area—by typing a place name or by interactively selecting an area on the map. Once you have defined the search area, you can define additional search criteria including content type, content theme, and keywords. You only need to define one parameter of your search (geographic extent, content type, content theme or keyword). However, each additional search parameter helps you narrow your search. Use some or all of the search parameters, depending on the broadness of your search.

Once you have defined the search parameters, execute your search by clicking Start Search. Datasets matching the criteria you specified are listed in the right panel.

  DEFINING THE SEARCH AREA
 

There are two ways to define the search area - by typing in a place name or by interactively selecting an area on the map. If you know the name of the area for which you want data, Somerset County for example, it maybe easier to type in the place name and press Find. If you know where the area for which you need data is located, but do not know the exact name of the area or the area cannot be defined by a single place name, you can zoom in and select it on the map.

TYPING A PLACE NAME

When you type a place name and click Find, NJGIN Explorer returns a list of matching place names. For example, you may want data on the town of Cape May, but your search results also include Cape May Point, Cape May Courthouse and Cape May County. Just click on the correct name and the map of New Jersey zooms in on the selected location.

SELECTING AN AREA ON THE MAP

Use the Zoom In, Zoom Out, and Pan tools to find an area on the map. Once you are zoomed in enough to see the area, use the Select Search Area tool to select it on the map.

Zoom In
 Zoom In

Click the Zoom In button, move the mouse pointer to the desired location, then click and drag a box around an area of the map. When you release the mouse button, the map zooms in to the selected area.

Zoom Out
 Zoom Out

  DEFINING SEARCH CRITERIA
CONTENT TYPE

To Search by type of content, click the Choose content type dropdown arrow and click one of the following categories:

Data:
This category includes live, downloadable and offline data.

Live Data and Maps are dynamic services that allow direct interaction with map content, generally via client GIS mapping software. They are delivered in one of two ways: as a cartographic image or “snapshot” of a map, or as compressed vector features that are streamed to you. Streamed features allow for greater client-side interaction including dynamic labelling, feature symbolization, and map tip creation. You do not need to download anything to use live data—just add it to your map and begin exploring.

This content type also includes data that can be accessed via database connections. This data access mechanism is usually available only to a limited audience. Please read metadata carefully.

Downloadable Data includes downloadable files containing map features. After the data has been downloaded to your computer, it can be added to your map.

Offline Data can be ordered on CD or in some other format. Offline data cannot be downloaded directly to your computer.

Documents:
This category includes map files, static map images, and other documents used in conjunction with geographic data.

Map Files are digital maps that can be readily viewed in a mapping application. Maps created for ArcReader and ArcMap are examples of digital maps that fit into this category.

Static Map Images are map image files. You cannot directly interact with static map images as you do with live data and maps, but you can view them and download them to your own computer.

Other Documents include text files, spreadsheets, and other files containing geographic information used in conjunction with geographic data.

Resources:
This category includes clearinghouses, GIS applications, geographic services, and geographic activities.

Clearinghouses are Web sites that either provide links to free geographic data or allow you to directly download data.

Applications are custom-built GIS applications served over the Internet, usually with a complete user interface. Many require only a web browser for use.

Geographic Services are Internet services that perform basic geoprocessing tasks on map features, such as address matching and buffering. Geographic Services are sometimes referred to as GeoServices.

Geographic Activities are an event or set of events that are geographic in nature. This includes activities such as land surveys, geographic explorations, GIS conferences, and more. The information about these events can be presented in many forms, such as a Web site.

CONTENT THEME
