Another way to view various areas of interest is to save these views with an option called a Bookmark. The bookmark facility is available in most GIS software. You are given the option of naming the bookmark when you create it or leaving it with a default name. Either way, you can quickly return to that map view by selecting the book mark option from a menu option.
Once you are in your area of interest you may wish to find out further information about the data within your map. Various selection tools including an information tool will enable you interrogate your map without having to create expressions with an SQL facility. In case SQL is new to you this stands for the Standard Query Language which is used within GIS software to ask questions about the attribute data associated with the map. These questions can be about subjects as diverse as population size, crime statistics and rainfall data or whatever data is present within the attribute data of the layers within the map.
Behind each layer in your map is at least one attribute table which can contain information which can be displayed within the map. In some cases several attribute tables can be joined to further enhance the information that can be obtained and presented through the map options. This presentation of results is often achieved by creating thematic maps from the attribute data. Additionally you can use the information tool to quickly view attribute information from the points, lines or polygons within the map. You can click on a single vector object or use a variety of selection tools to highlight multiple features. The data highlighted in the map is also automatically highlighted within the attribute table. This table may or may not be open within the mapping software. However, this does not stop the data in the attribute table from being highlighted. In the same way as data can be highlighted through the map window, information can be highlighted by clicking on rows within the attribute table window. Clicking on one or more rows within the table will highlight the same vector objects within the map. Normally there will be an option within the GIS software to zoom in to the selected data on the map by pressing on an option button within the attribute table.
