How to Use the Interactive GIS Mapping Tool
The ARCVIEW Internet Map Server (IMS) is a program for displaying and querying maps over the Internet. The maps are interactive - a user can zoom in and out of maps, with different amounts of detail being presented at different spatial scales. IMS allows different kinds of map layers (roads, land use, water bodies) to be turned on or off, so customized maps may be created. A user can also perform interactive queries to collect information about different items on the map. It is thus a fairly powerful way to distribute GIS data over the Internet.
The following primer covers the basics of using IMS - how to get and retrieve information. In the few minutes it takes to read this, you'll learn all you need to know to interact with the Lower Cape Fear River maps.
Getting to the IMS
Clicking on one of the links causes a lot of things to happen: 1) it accesses a live copy of ARCVIEW residing on the UNCW GIS server, 2) it loads all the appropriate data, and 3) it delivers the data over the Internet to the web browser on your computer. As a result, these links can be slower than most web links, although in most cases the maps will be delivered in under a minute.
The IMS Display
The IMS display
has three primary sections: A toolbar for performing various map operations,
an interactive legend that allows different layers to be turned on or
off, and map viewing frame, that shows the map itself. The status bar
shown at the bottom of the screen provides information on map coordinates,
a map scale, and information on the status of current operations.
The toolbar at the top of the display contains a number of icons that allow you to manipulate the map. Their functions are described below:Using IMS
Most of the tasks you can perform involve interacting with either the legend or buttons along the top of the map. You can also use the Identify tool to retrieve information on map objects. The Identify tool returns information in a data table that opens to the right of the map window.
