Teaches how to draw Circle, Rectangle, Square, Special Polygon, Arc and Ellipse on a Map
Category : WEB GIS Education Documents
To create special geometric shapes in the GISLayer Software, the Layer Box should have a vector layer.
If you don’t have a vector layer Click on Data -> New Layer buttons to open panel and create a new layer using this panel.
The following screenshot shows the position of the Create Vector Layer Panel.
Step 1: Activating the Vector Layer
The vector layers that you create within the GISLayer Software or insert into the map using files are also layers that enable you to create and edit. To work on a layer, you must first activate the layer. For this, the radio button next to the layer name should be selected and the layer should be activated.
The following screenshot shows the location of the radio button.
Step 2: Enable Editing on Vector Layer
To enable editing of a vector layer in the GISLayer Software, click on the pencil icon in the top button group of the Layer Box panel. A click on the pencil icon will show the pencil icon in the right button group of the corresponding layer. Simultaneously, the Edit menu opens, which also contains drawing tools, and the layer can now be edited.
Special drawings are generally polygon drawings.
The following screenshot shows the active edit mode of the layer due to the numbered steps.
Step 3: Introducing the Special Drawing Tools in the Edit Panel
After you have enabled editing in the GISLayer software, the Edit panel will open automatically. Special drawings tool in this panel has 6 main geometry types to create. These can be listed as follows;
Draw Custom Polygon – (Triangle and polygon with any number of edges)
In the Draw Custom Polygon tool, the user can enter the number of edges. For example, if you want to draw an octagon, the number of edges is entered as 8.
The following screenshot shows the locations of these tools.
If the drawing is finished, the user can change the editing mode by clicking Stop button.
The following screenshot shows examples of Special Geometric Shapes.
