Tall al-Umayri Regional Survey

GIS Data Sets

These pages contain web enabled views of data from the Tall al-Umayri geographic information system (GIS). To view the maps, select a theme from the list at the left. The map you select will appear in this window. Certain themes in the maps will be hot. This means that objects in these themes are linked to data about the objects. These data can be accessed by clicking on the object, or by using the search tool. If you want additional information about specific archaeological sites from the Umayri hinterland survey, visit the Site Summary report.

Information about individual data sets can be obtained by clicking on Metadata in the list to the left.

Data sets can be downloaded by following the links to the download section. The downloaded data is in a GIS format and can be used only by software that can read the ESRI interchange data format (i.e. *.e00).

Different browsers behave differently when viewing the maps, recent versions of Internet Explorer and Netscape Navigator work best.

There are a number of tools that will help you navigate the maps. These are listed and described below.

Tool	Description
	The Cursor tool can be used to query objects in the map. Normally an arrow shape, when it is passed over an object in the map that is hot, it will change to a hand. The hand can be held over the object and a simple identification of the object will appear (for example, holding it over an archaeological site will cause the site number to appear). If you use the cursor to click on a hot object, a summary from the database will open in a new window.
	The zoom tool allows you to zoom in to get a closer look at portions of the map.
	On the sides and corners of the border surrounding the map there are arrows that allow you to pan around the map.
	As you pan around the map, a locator window keeps track of your movements around the map. You can also click in the locator window to pan to particular locations. If the locator window interferes with your view of the map, you can click on the locator icon to the left of the map and it will disappear.
	If you click on the legend button to the left of the map, a legend for the map will open in a new window.
	Clicking on the print button will print the map as it appears in your browser window. Note that the map will print at the bit depth of the screen image (usually somewhere between 72 - 96 dpi) so the quality will be marginal.
	The find button opens a query dialog that allows you to search for particular objects in the map. The query capabilities of this application are limited. You can search for the first word in a record or for exact phrases, but not for any word in a record. You can use wildcards to help you search for words that are not the first words in the record, or to construct or statments. For example, if you are searching for Wadi Bisharat in the hydrography cover: Typing Wadi in the search dialog will return a list of all wadis, from which you can select Wadi Bisharat. If you click the "exact phrase" box and type Wadi Bisharat, only those records containing Wadi Bisharat will appear. If you type Bisharat, nothing will appear because it is neither the first word in the record nor the exact phrase. Use * to represent any character. If you type *Bisharat all records containing Wadi Bisharat will appear. Use | to construct or statements. If you type *Bisharat|*Mashur, all records containing either Wadi Bisharat or Wadi el-Mashur will be returned.
