| - | ====== Load a map ====== | ||
| - | |||
| - | Using map viewer, there are actually four ways you can load a map (or a group of maps, by using the CTRL key on file selection dialog):\\ | ||
| - | \\ | ||
| - | {{ :map_viewer:load_menu.png?nolink& |}}\\ | ||
| - | Load map (cleaning map list). | ||
| - | Will erase the current map stack (label "Maps" on main dialog). | ||
| - | \\ | ||
| - | Load map (keeping map list). | ||
| - | Will *NOT* change current map stack, the new loaded map will be on top of the stack and *visible*. | ||
| - | Every incompatible map (different number of lines or columns) will be turned off (invisible). | ||
| - | Keep in mind that if you open a incompatible map, the current transformation will be erased and the | ||
| - | default transformation (which renders to full screen) restored. | ||
| - | \\ | ||
| - | Load map on selection | ||
| - | Will load the new map replacing the selected map. This option is only available if there is a map loaded. | ||
| - | All transformations (histogram, palette, pan, zoom) will be untouched. The new map will try to match the | ||
| - | active map layer selection. | ||
| - | \\ | ||
| - | Load viewer state | ||
| - | Will load a entirely new viewer state, replacing the map stack, the background color, loaded palettes, histogram | ||
| - | transformations and everything else. | ||
| - | \\ | ||
| - | \\ | ||
| - | ---- | ||
| - | ==== Map loaded, so what? ==== | ||
| - | After your map is loaded, you can see it on the "Maps" stack on the right.\\ | ||
| - | \\ | ||
| - | {{ :map_viewer:loaded_map.png?nolink& |}}\\ | ||
| - | Initially, your map will be loaded **Collapsed**. We do this because the functionality of **each** map | ||
| - | is contained inside its "row" in the map stack. To expand, just click on the expand arrow.\\ | ||
| - | {{ :map_viewer:map_arrow_expand.png?nolink& |}}\\ | ||
| - | \\ | ||
| - | After expanding, your map will look like this on the map stack:\\ | ||
| - | {{ :map_viewer:loaded_map_expanded.png?nolink& |}}\\ | ||
| - | For maps with category information bundled, it will look like this.\\ | ||
| - | {{ :map_viewer:loaded_map_category.png?nolink& |}}\\ | ||
| - | You can see a new button, this is just a toggle between "normal" mode and "category" mode. Inside the category mode, the map transformation is ignored and the category colors | ||
| - | are used instead. Also, when showing legends in category mode, category colors and names are shown instead of the legend range. | ||
| - | \\ | ||
| - | \\ | ||
| - | ---- | ||
| - | ==== Map information ==== | ||
| - | |||
| - | You can retrieve map information by clicking on the icon {{:map_viewer:info_icon.png?nolink&|}} | ||
| - | |||
| - | {{ :map_viewer:map_info.png?nolink& |}} | ||
| - | |||
| - | This information comes from Dinamica EGO itself, the available rows can vary from map to map. | ||
| - | |||
| - | <note tip> | ||
| - | Tip: It is possible to assign aliases to maps and map groups. You can set the alias on the top part of the information dialog. | ||
| - | </note> | ||
| - | |||
| - | ---- | ||
| - | ==== Map functions ==== | ||
| - | The functions you have for **each** map are described below:\\ | ||
| - | \\ | ||
| - | {{:map_viewer:loaded_map_buttons.png?nolink& |}} | ||
| - | 1) Change map layer. If your map has many layers, you can select the active layer to be shown. Only one layer can be use at time.\\ | ||
| - | 2) Change map [[color_palette|palette]].\\ | ||
| - | 3) Opacity (by default, viewer show opaque maps, but you can set a transparency threshold and adjust stack to combine maps).\\ | ||
| - | 4) [[Viewer Image Expression|Image Expression]] (calculate expression - just like calculate map on Dinamica EGO - for map values).\\ | ||
| - | 5) [[histogram|Histogram]] transformation.\\ | ||
| - | 6) Edit color [[color_palette|palette]] selected on the left combo box (2).\\ | ||
| - | 7) Toggle category view (only available for maps with category information).\\ | ||
| - | 8) Toggle map visibility.\\ | ||
| - | 9) Remove map from [[map_viewer_interface|stack]]\\ | ||
