Version 2.3.9

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.

Image:GIS_Symbology_2.3.9_03.jpg


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.


Image:GIS_Symbology_2.3.9_05.JPG


If there is alphanumeric information the system identifies the individual values and automatically generates the classes.

If you want you can also define the classes according to your own criteria:
Image:GIS_Symbology_2.3.9_06.JPG


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.

5. To erase a class, click on the Delete Class button.

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.


Image:GIS_Symbology_2.3.9_14.JPG


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 Image:GIS_gis_Edit_03b_19.png located at the bottom-left of the symbology tab.

Then a window opens asking if where you want to save the .sim file

Later, to use this class file you only need to do the reverse process using the Import symbology button Image:GIS_gis_Edit_03b_18.png located at the bottom-center of the Symbology tab.

Previous Versions

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.


Image:GIS_gis_Edit_03b_01.jpg


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.


Image:GIS_gis_Edit_03b_02.jpg


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.


Image:GIS_gis_Edit_03b_03.jpg


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”.


Image:GIS_gis_Edit_03b_04.jpg


If the data is alphanumerical, the application identifies the unique values and creates the classes automatically.


Image:GIS_gis_Edit_03b_05.jpg


If you want, you can customize the classes:


Image:GIS_gis_Edit_03b_06.jpg


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.

Image:GIS_gis_Edit_03b_07.jpg To delete a class, click on the “Delete Class” icon.


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.

Size: When the layer contains points, you can modify the size of them.


Image:GIS_gis_Edit_03b_12.jpg


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.

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.

Color ramp

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.

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 Image:GIS_gis_Edit_03b_19.png, located at the bottom-left of the symbology tab.

Then a window opens asking if where you want to save the .sim file

Later, to use this class file you only need to do the reverse process using the Import symbology Image:GIS_gis_Edit_03b_18.png button located at the bottom-center of the Symbology tab
