Edition Tools

Tools for vectorial editions and classification process. These tools are displayed on the main interface only when the user opens the edition mode.

Tools effective on Direct Edition are identified with DE and tools effective on Edition Through Project are with ETP.

Select geometry. Click on the desired geometry to select it. Hold the Ctrl key to select more than one geometry. (DE, ETP)

Select by Drawing Area. Click and hold anywhere in the visualization area and move the mouse to cover the area that contains the desired geometries. Every geometry touched by the tool will be selected when the click is released. (DE, ETP)

Select cell. Activate the tool and click on the cell to select it. Click on a selected cell to release it. Cells that have been previously selected by a user are said to be “locked cells” and cannot be selected by anybody else working on any of the projects from that database. After selecting the desired cells, click once again in the tool to release it and resume the data visualization. The number of cells that can be selected using this tool will depend on the project´s configuration. It is only possible to select cells that are completely or partly within the Area of Interest defined by the started process. (ETP)

Select cells in the box. Click on the tool and TerraAmazon will select as may cell as possible among the cells displayed in the drawing area. The number of cells that can be selected using this tool will depend on the project´s configuration. It is only possible to select cells that are completely or partly within the Area of Interest defined by the stared process. (ETP)

Unselect all cells. Click on the tool and all of your selected cells will be released. However, it does not release the cells you have selected in a different project. (ETP)

Delete geometries. Use one of the selection tools to select the geometries you wish to remove and click on this tool to delete. Deletion is permanent. (DE, ETP)

Move geometries. Use one of the selection tools to select the geometry to be moved. Then, use this tool to move the geometry. Save the changes with the right-click or with the tool . (DE)

Create polygon. Click to insert points to the polygon and right-click to finish the polygon. Every polygon created is automatically selected when finished. Visualization tools can be used while creating polygons without releasing this tool. (DE, ETP)

Clear current class. Use the same way as the Clear classification tool. The difference is that this too affects only the polygons in the output layer that stores the class currently selected in the class box. If the project has only one output layer for all of it´s classes, then both clear tools will ha the same final result. (ETP)

Clear classification. Removes the areas of the output polygons that are overlapped by the input polygons. Use one of the tools to draw the input polygons on the area you wish to clear, drawing over previously classified polygons, if necessary. Click on this tool to clear. You can also use one of the selection tools to select either polygon from the draft layer (input polygons) or from the output layer itself and then click on this tool to clear. Affects only the polygons in the output layers. (ETP)

Classify geometries. Create new input polygons, using one of the provided tools, or select existing polygons, by using one of the selection tools and chose the new class to be applied to them. Click on this tool to trigger the classification process and apply the class to the polygons. (ETP)

Clear Class Classification. Removes the class classification of the output polygons that are overlapped by the input polygons. (ETP)

Reclasify. Changes the classification applied to previously classified polygons. Use one of the selection tools to select the desired polygons and chose the new class to be applied to them. Click on this tool to reclassify. It is also possible to draw new input polygons, using the drawing tools, and then click on this tool to reclassify. (ETP)

Select multi-layer. Select geometries from the output layers that are visible in the drawing area. Click on the desired polygon to select it. Hold the Ctrl key to select more than one geometry. (ETP)

Select multi output layer. Select geometries from the output layers that are visible in the drawing area. Click and hold anywhere in the visualization area and move the mouse to cover the area that contains the desired polygons. Every polygon touched by the tool will be selected when the click is released. (ETP)

Insert vertex. Insert a new vertex in a geometry. Click on the Insert Vertex tool and double click on the line where the vertex must be inserted. Available for lines and polygons. (DE)

Move vertex. Move a vertex of the geometry. Click on the Move Vertex tool and drag the desired vertex to the new position. Available for lines and polygons. (DE)

Delete vertex. Delete a vertex of the geometry. Click on the Delete Vertex tool, press SHIFT key and click at the vertex to remove it. Available for lines and polygons. (DE)

Aggregate Geometry. Adds a new area to the polygon. Use one of the selection tools to select the geometry that will be modified. Click on the Aggregate Area tool, draw the additional area. The new area must intercept the selected polygon. It is necessary to save the change using the save tool . (DE)

Subtract Geometry Area. Remove a determined area from the polygon. Use one of the selection tools to select the geometry that will be modified. Click on the Remove Area tool, draw the area that will be removed. The drawn area must intercept the selected polygon. It is necessary to save the change using the save tool . (DE)

Merge Geometries. Attach two or more polygons keeping the attribute of one of them. Use one of the selection tools to select the geometries that will be united. Click on Unite polygons tool, select the Id of the polygon whose attributes will be kept. It is necessary to save the change using the save tool . (DE)

Save. Saves the changes made in existing polygons using one of the tools: Aggregate Area, Remove Area and Unite Polygons. In some tools, Save has the same effect as a right-click. (DE)

Cancel editions. Click on this tool to remove unfinished polygons, that is, polygons that were not yet finished by a right-click. This tool does not alter polygons already finished or classified. (DE, ETP)


Class box. Shows the classes available for the active project. Select the desired class in this box and then use one of the classification tools to attribute it to the outcoming polygons of the classification process. (ETP)

Snap tool. Attracts the cursor to vertexes and edges of existing polygons. Click on this tool to turn it on and then select one of the tools to create polygons. When the cursor is attracted
