Mapas

Introdución

“Map” type documents allow you to design and combine all the elements you wish to have on a printed map.

Acceso a mapas

You can access “Map” type documents via gvSIG's "Project manager".

Click on “New” to create a new map. When you have created the document (it will appear by default as “Untitled– 0”), you will be able to insert elements, rename the map, delete it or access its properties and modify them. When the map is open, it will appear in gvSIG as shown below:

Configurar las propiedades de un nuevo mapa

You can access the map properties window from the “Project manager” by clicking on the “Properties” button or from the view by going to the “Map” menu and then to “Properties”.

You can use the properties window to rename the map, change its creation date, add an owner and comments. You can select some default characteristics by activating the corresponding check boxes:

• Active grid: Activating the grid means that any element inserted in the map will be adjusted to the grid. Remember the following two points if you enable “Active grid”:
  1. The horizontal and vertical grid spacing defines the distance between the different points which make up the grid. This can be modified by inserting new values in the text boxes.
  2. Output size of the chosen document (A2, A3, A4,...). The zoom tools may need to be used to be able to view the grid when you open the document.
• Visualise grid: If this box is disabled, the grid will not be viewed when you open the newly created document.
• Enable ruler: By enabling this check box a ruler appears which can be used as a drawing aid.
• Editable: If you do not enable this option, the objects that make up the map will be blocked, thus preventing modifications.

Preparar página del mapa

You can use this tool to define the working area, i.e. the size and properties of the page to be used for the map layout. You can access this tool by clicking on the “Configure page” button in the tool bar or from the menu bar by selecting the “Map” option and then “Prepare page”.

When you have selected the tool a new window will appear:

Page size: The pull-down menu allows you to define the source and size of the paper to be used to print the map. You can select a standard size or define your own.

Measuring units: You can select the units of measurement for the page Height and Width. Orientation: This defines whether the paper will be printed horizontally or vertically.

Margins: This allows you to define the page’s four margins. The ruler is adjusted to fit in with the page margins.

Resolution of the result: You can choose between high, low and normal resolution. When you have finished configuring the page, click on the “Ok” button.

Elementos que se pueden insertar en un mapa

Introducción

gvSIG can be used to add the following cartographic elements to a map:

• Views
• Images
• Scale bars
• Legends
• Graphic objects
• North
• Texts
• Boxes

Many of these cartographic elements are closely linked to the “View” document, so that when changes are made in the view, they are shown in the map (changes in zooms, panning, legend modifications, layer organisation, etc.). You can access the different options from the tool bar or by going to the “Map” menu and then to “Insert”.

Insertar una vista

You can insert a view in the map by clicking on the “Insert View” button in the tool bar.

Place the mouse pointer on one of the vertexes of the rectangle which define the view area, left click and drag the pointer to the opposite vertex and drop. A dialogue box appears in which you can define the view-type element properties you have just inserted.

View: You can use the text box to select the view you wish to insert, if there is more than one.

Active link: If this check box is enabled, any changes made in the view (changing colour, adding a layer…) will be shown in the map. Remember that scale changes will not be affected by this check box, because these modifications are regulated by the scale pull-down menu which appears below.

Scale: Select one of the following three scale types: Automatic: If this option is chosen, any scale change made in the view will automatically be shown on the map.

Keep visualisation scale: In this case, although you change the view frame in the map, the layer associated with the view will not resize itself and will keep the same size it has in the view.

User-defined: This option allows you to define a specific scale.

Quality: This defines the visualisation, as either presentation or draft quality.

Degrees: This allows you to specify a degree of rotation when the view is inserted in the map. This option also appears in the rest of the elements that can be inserted: images, scales, legends and texts.

Insertar una leyenda

The legend represents the visible layers of the ToC in the selected view. If a legend is inserted, it is added in the same order as it appears in the ToC.

In the view frame, select the view the legend is associated with. The order in which the legends in the ToC will be added appears in the panel on the right.

Insertar escala

This tool allows you to insert a scale (associated with the view) in the map.

The scale bar dialogue box is shown below:

View frame: Select the view, if there is more than one, the inserted scale is related to.

Bar: Select the type of scale you wish to insert (numeric or graphic). By clicking on the pull-down menu, you can see the different options with which the scale to be inserted in the map can be shown.

Intervals: Select the number of intervals, what each one represents and the number of divisions to the left of the 0 that you require in the interval.

Scale: You can use this section to make the numeric scale appear above the bar.

Units: This defines the graphic scale units of measurement (metres, Km., etc.).

Labels: You can use this box to select the label colour, font and location (numeric scale, units…).

Insertar el símbolo Norte

If you click on the “Insert “North” button in the tool bar, you can insert a “North” symbol in the map. Place the mouse pointer on one of the vertexes of the rectangle which define the space to be occupied by the symbol, left click, then drag the pointer to the opposite vertexes and drop. A dialogue box appears in which you can choose between several default North symbols.

You can add new symbols by copying them in the folder:

bin/gvSIG/extensiones/com.iver.cit.gvsig/northimages of the folder you have installed gvSIG in.

The acceptable format for North symbols is SVG (Scalable Vector Graphics). To add a new North symbol you will need to use an external application (such as Inkscape http://www.inkscape.org). Moreover, in order to ensure that the new North symbol will be correctly processed by gvSIG, it is better to base it on one of the default symbols suggested by gvSIG.

Insertar un cajetín

gvSIG has a tool which allows you to insert a box in the map.

If you wish to insert a box, select the following button from the tool bar:

Left click on the map area you wish to insert the object in and drag it to create a frame which will define the future box size.

When you drop it, a window will automatically appear for you to define some of the box properties.

Insertar imagen

You can use this tool to insert an image in the map.

You can access this tool by clicking on the “Insert image” button or by going to the “Map” menu bar, then to “Insert” and then to “Image”. If you activate this tool and create the frame to insert the image on the map (similar to “Insert view”), the following dialogue box will appear:

If you click on the “Browse” button, you can select the file path of the image to be inserted. You can insert an image in any of the following formats: jpeg, jpg, gif, png and bmp.

From gvSIG version 0.4 onwards, you can add vector files in SVG format to the map.

Insertar un texto

Texts, which can also be inserted by clicking on the corresponding button in the tool bar or by selecting “Maps” then “Insert” and then “Text”, are defined in the following dialogue box.

You can write the text you wish to appear in the map in the text box.

Align: This can be used to select the alignment type (left, centred or right respectively).

Font: This can be used to select the font type. You can also set the font size by activating the corresponding check box and specifying the required size in the text box.

Degrees: This defines the text slope, from the horizontal axis.

Frame: This allows you to define a border around the text you are using.

Text field title: You can also define a title for the corresponding border.

Gráficos

Insertar un gráfico

You can insert the following types of graphic elements:

• Points
• Rectangles
• Circles
• Lines
• Polylines
• Polygons

All these elements can be inserted by going to “Insert” in the “Map” menu or by clicking on the corresponding button in the tool bar.

If you wish to insert a graphic element, left click on the map in the place you wish the graphic element to be inserted in.

Editar los vértices de un gráfico

When you have inserted a graphic element, you can edit its vertexes. You can access this tool by going to the "Map" menu, then to "Edit" and then to “Edit vertexes” or from the following tool bar button.

If you wish to edit a vertex in a graphic element, select the element from the map and go to the tool.

Deshacer/rehacer acciones al crear un mapa

These tools allow you to undo actions you have taken on the map or redo the actions you have previously undone.

You can access these tools by clicking on the “Undo” (left-facing arrow) or “Redo” (right-facing arrow) buttons

or by going to the menu bar and selecting the “Map” option.

You can also undo several actions by using the command stack. This tool allows you to view the actions you have carried out on the map and decide which point you wish to continue working from.

The advantage of this tool is that you can undo or redo several actions at the same time. However, you cannot undo a specific action, i.e. if you take six actions, you cannot undo just the fourth one. The sixth and the fifth action will also be undone.

You can also access this tool by clicking on the command stack button in the tool bar

or by going to the “Map” menu bar and then to “Command stack”.

Borrar un elemento seleccionado en el mapa

You can delete any of the elements selected in the “Map” by clicking on the “Delete selection” button in the tool bar.

Maquetar un mapa

Introducción

Propiedades de un elemento insertado en el mapa

When the elements have been inserted in a map, you can access its properties.

Select the element. Right click to show its contextual menu and select "Properties".

Alinear elementos

You can access this tool by going to the “Map” menu, then to “Graphics” and to “Align”.

This tool can be used to modify the alignment, distribution and size of the map elements selected.

In the layout: If this button is enabled, the tools in the "Align" menu will use the map limits as a reference. If it is disabled, the selection will be used as the reference.

Alignment: The tools in this section allow you to align the selected graphics (place a series of objects on the same axis) according to your needs (left, horizontally centred, right, top, vertically centred and bottom).

Distribution: This allows you to space out objects at equal distances over a specific area. Match size: This allows you to modify the size of a selected object, using another object as a reference. The adjustments are made based on the largest object in the selection.

The object sizes can be made to coincide in width, height or both.

Space: This allows the selected elements to be “spatially distributed”.

If, for example, you decide to spatially distribute two selected elements in the map (using the active "In the layout" button), the objects will be moved to the same distance from the map’s left and right-hand margins when you click on the first option.

If we click on the second button, the images will be moved to the same distance from the top and bottom margins.

Agrupar y desagrupar

You can access this tool from the tool bar by clicking on the buttons

or by going to the “Map” menu, then to “Graphics” and to “Group” or “Ungroup”.

Colocar delante y detrás

You can access this tool by going to the “Map” menu then to “Graphics” and then to “Bring to front” or “Send to back” respectively or from the tool bar by clicking on the following buttons:

You can use this option to change the viewing order of the selected elements in the map by bringing them to the front or sending them to the back.

Enmarcar elementos

This tool draws a frame around a selected element or elements.

You can access this tool from the tool bar by clicking on the following button

or by going to the “Map” menu and then to “Graphics” and "Graphic line".

The available options are shown in the following dialogue box:

The different options include a check box which allows you to group the graphic line and the object you have inserted in the map so that they make one single element and not two separate ones.

If you click on the “Configure” button, another dialogue box appears which can be used to define the properties of the graphic line or frame to be inserted.

Select the properties and click on the “Ok” button if you wish to use the new configuration or "Cancel" if you wish to maintain the default values.

Modificar tamaño y posición

You can access this tool by going to the tool bar and clicking on the following button

or by going to the “Map” menu then to “Graphics” and to “Size/Position”.

This tool opens a dialogue box which allows you to specify the size and position of the selected element.

You can edit the different text fields and modify and specify the object’s size and position.

Herramientas de navegación por el mapa

You can use these tools to move around and zoom in and out of the maps page.

You can access the tool from the tool bar or by going to the “Map” menu and then to “Navigation”.

Zoom in: This allows you to zoom into the page.

Zoom out: This allows you to zoom out of the page.

Panning (Frame): This allows you to move the map page.

Full extent: This carries out a full zoom of the page.

Scale 1:1 zoom: This carries out a “real” size zoom of the configured page.

Zoom in: This zooms into the centre of the page.

Zoom out: This zooms away from the centre of the page.

Herramientas de navegación por la vista

There are several tools you can use to navigate around the view.

Zoom in: Enlarges a particular area of the view.

Zoom out: Reduces a particular area of the view.

Full extent: Full zoom of the total area included in all the layers of the view.

Panning: This allows you to change the view zoom by dragging the viewing field all over the view with the mouse. Click and hold down the left button of the mouse then move the mouse in the direction you require.

Crear una plantilla

Saving templates gvSIG allows the configuration of a map to be saved as a template.

This can then be used at a later date with different data sources.

The element distribution and properties from a map can be saved.

If you click on the “File” menu then on “Save as template”

a dialogue box appears so you can save your .gvt file which can be recovered at a later date and will allow you to reconstruct the map configuration.

Herramientas de exportación a postScript y pdf

You can use these tools to export a layout to a postScript and/or pdf file by going to the "File" menu and then selecting "Export to ps" or "Export to pdf" respectively

or by clicking on the following buttons in the tool bar:

This opens a dialogue box in which you are asked to specify a file to save the resulting postscript file (with the .ps extension) or pdf file (with the .pdf extension). When you have selected where you wish to save the document, click on “Save”.

Imprimir un mapa

This option opens the printing dialogue box from which you can select the printing options (selecting printer, quality, etc.).

N.B.: The specifications which are not enabled depend on the type of printer installed.
