Changing the number of classes will update the range intervals. Shown below is the same Contour example, but this time with eight classes being created instead of four. Note: currently both the Legend and the Print Menu legend will not display the colours and attributes of the edited selected symbology. (the selected feature symbology does appear in the Print Menu map) Quick Search To quickly find a specific map feature, use the Quick Search function. For example, to zoom to Bendigo, just type Bendigo in the Quick Search data entry box. As you type this name, map features that have been linked to what is typed will automatically appear in a paged listing. When the whole word is entered, the page listing will display those map features that have the word 'Bendigo' associated with them. Map features that best match the typed name appear first in the page listing. The Quick Search function also accepts wild card characters. Use an asterisk (*) to replace zero or more characters in a search word. Use a question mark (?) to replace exactly one character in a search word While you type into the Quick Search data entry box, GeoVic 3 first tries to find an exact match. If an exact match is found, them that record is displayed to you. If no exact match is found, then possible matches are displayed for you to choose from. Because GeoVic 3 has access to more than 800 layers, only a small selection of layers have been made available for the Quick Search utility. The layers that Quick Search uses are shown in the Layers (Key and Quick Search) section. (see the Table of Contents) 2. Main Tools and Buttons Zoom In The Zoom In tool allows you to interactively zoom to a specific location. This is done by first clicking and making the Zoom In tool active. The Zoom In function can then be used in either of two ways. 1. Use the mouse and click anywhere on the map. This will decrease your map scale by half. Or 2. Click and hold the mouse down on the Main Map Display. You will see a box being created which represents the desired zoom location. When you have defined the area of interest, release the mouse button and the Main Map Display will zoom to the area defined. See below.
Also note in the above polyline that there is a orange dot in the centre of the polyline, and another at the bottom right corner Once a polyline is selected you can change the polyline’s appearance by clicking the arrow next to the Line tool. Text can also be added to a selected polyline. The position of the text will be in the centre of the polyline The shape of a selected polyline can also be adjusted. Position the mouse over one of the orange dots that appear overlapping a polyline vertex, until the mouse cursor changes to . When this occurs, a vertex of the polyline has been selected. Click the mouse, and drag the selected vertex to a new position. To change the position of a polyline, grab with the mouse the orange dot that appears in the centre of the polyline. To change the size of a polyline, grab with the mouse the orange dot that appears in the right bottom corner of the polyline. Markup / Redline Tools - Rectangle Rectangles can be added to the Main Map Display by first clicking the Rectangle button. Then click the mouse on the Main Map Display and drag the mouse. As you drag the mouse, a red rectangle will be generated, outlining the current shape. Clicking the mouse again, will cause a rectangle symbol to appear on the Main Map Display. The default appearance of a rectangle symbol will be solid yellow fill, with a black outline. Use the Modify button , together with the Fill and Line buttons to change the rectangle’s appearance. Text can also be added to the rectangle, and is placed in the center of the rectangle. The Modify button can be used to change the rectangle’s size and position. Markup / Redline Tools - Polygon The polygon symbol is very similar in operation to the rectangle symbol. To add a polygon element to the Main Map Display, first click the Polygon tool button. Then with the mouse on the Main Map Display, click in three different locations. An yellow shape will then appear on the map. Continue clicking till the desired shape is obtained, then double click to stop the operation. The outlined shape will then appear (if the default colours and lines types are not changed) as a solid yellow filled polygon with a black outline. As with the rectangle symbol, use the Modify button to add text, change position, change shape or alter the appearance of the polygon.
To delete a callout symbol, you first need to select the element using the Modify button. When a symbol is selected, the Delete button will become activated. Pressing this button will then delete the selected symbol from the Main Map Display. Markup / Redline Tools - Delete All By pressing the Delete All button, all redline symbology is removed from the Main Map Display. Markup / Redline Tools - Export features as shapefile Redline elements on the Main Map Display can be exported – but the results are not what you might be expected. In the example below, the following redline symbology is exported as shapefiles using the Export button. When the Export button is pressed, a popup display shown below will appear, asking for projection type. Currently, the shapefile projection parameters are not being exported correctly (this is a known bug), so leave the projection type as the default value – Geographic GDA 94. Hit the Export button. A zip file will be created, containing from one to three shape files. The shape files are simply named “Point”, “LineString” or “Polygon”. Shown below is the result of exporting the above redline symbology (using a GIS application named Arcmap). The redline point, point with coordinates and markers are simply captured as points. The redline polyline symbol is captured as a polyline shapefile, while the redline polygon and rectangle elements are captured as polygons. The redline callout symbol is only captured as a point – the point being the start (anchor) position of the callout. Note that no text, colour, line style, line thickness or fill colour is captured. No attributes exist in the shapefile’s attribute tables Markup / Redline Tools - Save and Load Functions NOTE: These functions are only available for Registered users. (i.e., you need to login) You can save redline elements in a web browser session. Simply click the Save button to capture the current redline elements. A popup window will appear, asking you to enter a name to the selected set of elements. Add a name into the textbox and hit OK. The elements will be saved under the name you typed in. ( and are saved under your registered identity on the GeoVic server)
