In this panel you will find different options to modify the appearance of the objects of the active layer, create object groups, select fill, border, labels, etc.
Create Object Classes
You can select if you want the to layer work as a unique class or with multiple classes.
When the layer works as Unique Class, all the objects have the same appearance: same fill color, same border color, etc.
The classes are groups of elements defined by a user-defined expression.
Once the classes are defined, it is possible to assign them an appearance (color, contour, labels, etc.) to visually distinguish them.
GeoAgro GIS can automatically generate the classes using the Wizard.
If there is numeric information, the software will take the minimum and maximum values and it divides them in equal parts, and assign them to ranges according to No. of Classes.
If there is alphanumeric information the system identifies the individual values and automatically generates the classes.
1. Click on the option Add new Class.
2. A new class will appear. Select it and assign a name to it in the Class Name column.
3. In the Filter column, define the attribute, condition and value using the wizard.
4. To add more classes, repeat the process.
Modify the the objects and classes appearance
Once you defined the classes, you can select them individually and modify their appearance with the Fill, Border and Layer tools.
Select the class that you want to modify.
In the Fill group you can select the styles and color to fill the objects.
1. Color: allows to select the fill color for the object.
2. Design: to select the texture of the fill: transparent (without fill), solid, striped, vertical lines, horizontal lines, etc.
4. Style: when the layer is lines, you can decide if you want it to be a line, a set of lines and dots, dots only, etc. When the layer is points, you can choose their shape between square, circle, cross, etc.
If you click on More Options you will see the following window:
In this form you can choose the style of the fill.
When the layer is lines, you can decide if you want it to be a line, a set of lines and dots, dots only, etc. When the layer is points, you can choose their shape between square, circle, cross, etc.
In the Border group you can define the characteristics of the object contours.
1. Color: it allows to select the color of the border.
2. Size: it allows to select the thickness of the border line.
3. Style: it allows to choose the appearance of the border line, dots only, dashed, etc.
If you click on More Options you will see the same options as for the fill panel, and you can select the style of the border.
In the Label group you can select the attributes of the layer structure that will be show in the map, above the objects.
1. Attribute: select the attribute of the associated structure that you want to show.
2. Font: select the font, font size and color for the label.
If you click on Apply these parameters to all the classes, these characteristics will the copied to all the existing classes.
If you click on More options, you can select more options for the layers.
1. Position: choose the position of the layer in relation to the object.
2. Separator: select the separator in case you select to show two or more attributes.
3. Duplicates: there are labels that are repeated for two or more objects. If you check this option, you will see one label per object, otherwise just one label will be shown for those objects.
4. Overlap: it allows to overlap the labels.
5. Angle: select the angle of the text.
Export and import of symbology configuration files
You can export the symbology of a layer for later use in other layers. Once the configuration of symbols is finished (and saved the changes) you can export it to a configuration file by clicking on the Export symbology button located at the bottom-left of the symbology tab.
Then a window opens asking if where you want to save the .sim file
In this panel you will find different options to modify the objects appearance of the active layer, assign them fills, borders and labels, create elements groups, etc.
Create objects classes
Contents: You can select to work with layers as unique class or various classes.
If you select “Unique Class”, all the layer objects will have the same appearance: the same fill color, the same border color and size, etc.
The “Classes” are elements groups based on a wording predefined by the user. For example: “Perimeter > 300”, FarmID = 1, etc.
Once the classes are defined, you can assign an appearance (color, label, border, etc.) in order to make a visual difference.
Identifier: The objects will be grouped in classes taking as a reference the information included in the associated structure, so firstly you need to define the attribute you want to consider.
GeoAgro GIS can do the classification automatically if the identifier contains numerical information. The application calculates the minimum and maximum values and divides them by the number that the user defined in “No. of Classes”.
If the data is alphanumerical, the application identifies the unique values and creates the classes automatically.
If you want, you can customize the classes:
1. Click on the “Create New Class” icon.
2. The new class will appear. Select it and enter a name in the “Class Name” field.
3. In “Wording” define the attribute, condition and value of interest.
4. If you want to add more classes, repeat the procedure.
Modify the objects and classes appearance.
Once the classes are listed, you can select them individually and modify their appearance setting the options “Fill”, “Border”, “Label” and “Color Ramp” (if it is a point layer).
1. Select the layer whose appearance you want to modify.
In the “Fill Tab” you can select styles and colors to fill or paint objects.
Color: It allows selecting a color to paint the objects.
Pattern: It allows choosing the way the fill will be shown: transparent (without fill), solid, crossed, vertical, horizontal, etc.
Size: When the layer contains points, you can modify the size of them.
Style: This option is available only for line and point layers.
For line layers, you can define the line type, for example: solid, line dot, line dot dot, etc.
For point layers you can define the points form, for example: square, circle, cross, etc.
If you click on “Apply to all classes”, the fill settings will be for all the existing classes.
In the “Border Tab” you can define the layer objects contour.
Color: It allows selecting a border color.
Size: You can set the border line size.
Style: It allows you to define the border line type, for example: line, line dot, point, etc.
If you click on “Apply to all classes”, the border settings will be for all the existing classes.
In the “Label Tab” you can select a structure attribute to show on the map, over the objects.
Attribute: Select the associated structure attribute that you want to show.
Position: You can determine where to show the label on the object.
Font: You can select the label typography.
Size: It allows setting the text size.
Color: Select a text color in this field.
Background Color: It allows assign a background color to the labels.
Duplicates: Certain labels have the same description for two or more objects. If you check the option “Duplicates”, every object will have a label, although those labels are identical.
If you uncheck the option, only one label will appear, although this label belongs to various objects.
Visible: If you created some classes, you will be able to select which of the classes to show on the map by checking or unchecking this option.
If you click on “Apply to all classes”, the label settings will be applied to all the existing classes.
When you modify the appearance of points layers, it will also appear the “Color Ramp” option that allows generating classes.
Zones: Here you establish the number of classes to create.
Wording: The attribute you will use for the classification.
Minimum and maximum values: Here you define numerical limits for the classification.
Size: You can establish the variation of the points size.
Color: You can define the variation of the points color.
Export and import of simbology configuration files
You can export the symbology of a layer for later use in other layers. Once the configuration of symbols is finished (and saved the changes) you can export it to a configuration file by clicking on the button Export symbology , located at the bottom-left of the symbology tab.
Then a window opens asking if where you want to save the .sim file
