The Wyoming Public Land Initiative (WPLI) Resource Mapping Tool is a powerful but simple tool for displaying and exploring geospatial data. Among the features this application offers are the capability to overlay multiple "layers" of data on a basemap, view attribute information associated with features in those layers, explore the map by zooming and panning, and save or share user-designed maps as a PDF or URL. The various tools and features of this application are explained in this help document.
`Zooming in` is equivalent to decreasing the scale of the map -- you can see less of the overall map, but the region in your view will be "closer," i.e. will have more detail. `Zooming out` is equivalent to increasing the scale of the map -- you can see more of the overall map, but the region in your view will have less detail. This is an important concept in map-based applications.
There are five basic ways to change the scale of the map by zooming in and out:
Panning allows you to move around the map laterally and vertically. There are two basic ways to pan the map:
The "Home" button allows you to return to the map's default extent (i.e. resetting the zoom and position of the map).
In this application, a search bar is available to quickly locate and zoom to a number of important regions. Important or user-defined regions are often referred to as "Areas of Interest" (or AOIs). To use the search bar to locate an AOI, first click the top drop-down menu field ("Select category...") and select the areal category you wish to search by. After selecting a category, click on the second drop down menu field ("Search by name...") to select a specific feature to locate. You must choose a category before searching by name.
Note that you can type text into these drop-down menu fields. The menu will automatically complete your input from the available options as you type. Typing a partial name is also possible. For example, typing "canyon" would select all entries containing that string of characters (e.g., "Roger Canyon", "Canyons of Laramie", etc.).
A key component of this application is the ability to toggle various data-layers on and off. Layers contain data that are represented on the map as features. For example, a layer may show the locations of coal power plants, or the different types of vegetative ground cover for a region. Layers are "drawn" (or represented) on the map as points, lines, polygons, or symbols. A legend is integrated into the Table-of-Contents (TOC) to elucidate the map symbology.
The basemap is the default background (or "bottom") layer that is always turned on. There are several basemaps to choose from, and these are typically simple, and not accompanied by a legend. Data layers are overlaid on the basemap. Note that only one basemap may be displayed at any time.
When you first load the WPLI Resource Mapping Tool, the default basemap will be automatically be shown in the map. To display a different basemap, simply click the "Switch Basemap" button located in the top-right corner of the map. The panel shown in the graphic above will open with a variety of basemaps to choose from. Click one of these to change the current basemap. Note that this will have NO effect on the data layers or settings you are currently using, so it is "safe" to change basemaps at any time.
To turn on a data layer, simply click the checkbox next to the layer's name, or click on the layer name itself. The map will automatically update to display the selected layer.
Some layers will not be available at all display scales. When this happens, the layer name will change color and the checkbox will be "grayed" out -- in this case, the layer represents data that can only be viewed at specific zoom levels. Simply zoom in or out until the layer becomes available, then click on it in the TOC. Note that to turn this type of layer off, you must also be at a zoom level where the layer is visible.
To turn off a data layer, you can follow the same procedure outlined above. Once you have clicked on the layer checkbox or name, the map will automatically update to remove the selected layer.
Optionally, you may click the "Clear Layers" button. This will turn OFF all the layers, including any layers that are ON but not visible at the current zoom level. Note that this action does not apply to the basemap, and cannot be undone.
The TOC represents all data layers available to the user. These layers are grouped by category (or theme). Each category may have sub-categories containing their own data layers. Figure 2 (below) is an example of a category ("Land Divisions") and its data layers: "National Parks," "Cattle Pastures," and "Vegetation Type".
Figure 2. Anexample of a TOC category and its data layers.
To collapse or expand the contents of a category, simply click on the category name. For example, in Figure 2, clicking on "Land Divisions" would collapse this category's contents, hiding the three data layers within the TOC. Note that this does not turn off these layers on the map -- it simply hides them in the TOC.
To turn on or off ALL the active layers within a category (and any sub-sections within that category), simply click on the checkbox next to the desired category. Note that individual layers retain their state during this operation -- i.e., if all the layers within a category are unchecked, checking the category will not actually "turn on" those layers. In other words, a layer must already be "ON" for this action to take effect.
When this application loads, the default is such that all layers are OFF, and all sections are ON and COLLAPSED. Again, note that simply collapsing a category in the TOC has no effect on how the layers are displayed on the map.
To the left of each layer name in the TOC, you will find a small icon. This icon corresponds to the symbology (i.e., point, line, or polygon) used to draw the layer on the map. A collection of such symbols and their meanings is referred to as a "key" or "legend." Referring to the example in Figure 2 (above), you can see that the "National Parks" layer will be represented by a polygon with a green outline. The "Cattle Pastures" layer is a polgyon with a dark-red outline and a light-red fill.
A layer that represents more complex data may require multiple symbols. Notice the small box with a "+" symbol in it next to the "Vegetation Type" layer in Figure 2. Clicking on the "+" symbol will expand that data layer's legend, revealing all the symbols used in representing that data layer on the basemap. Once expanded, the "+" symbols becomes a "-" symbol that may be clicked on to collapse the legend.
Each layer has metadata ascribed to it. Metadata contains useful information about the type of data contained in the layer (e.g. where the data came from, when it was generated, or the entity in stewarding the data). To view the metadata for a layer, click on the small circle labeled "i" next to the on/off checkbox for the layer. This icon is visible in Figure 2 (above) at the far-left of each layer. Once the icon is clicked, a popup will appear with the layer's pertinent meta-data, along with any available links to additional information about that layer.
Every layer on the map is comprised of one or more individual features. You may see features represented as points, lines, polygons, or symbols. The capability to inspect a map feature allows you to highlight it and view any data associated with that feature. To inspect a feature, simply click on its representation on the map. A popup will appear, and you will see the feature highlighted on the map. Multiple features will be selected if they are overlapping or adjacent to one another at the point where you click.
Note that you must first turn on at least one layer before you can see OR inspect any features.
The draw tools panel is located below the "Select Basemaps" button in the top-right corner of the map. Click on the button labeled "Draw Tools" to open the draw tools panel. You may then choose from a number of tools that can be used to mark-up and annotate the map. Any points, lines, polygons, or text you draw on the map will be shown in your PDF map when you "Print to PDF."
Points are simple point-markers that represent or emphasize a single x-y (latitude/longitude) coordinate on the map. To draw points on the map, first click on the "Point" button in the "Draw Tools" panel. Then click on the map at the point where you wish to place the marker.
Polylines are lines that may be drawn "freehand" to represent curvilinear shapes. To use the line tool, click the "Freehand Polyline" button in the "Draw Tools" panel. Then, click on the map at the point where you wish to begin drawing. With your mouse-button still depressed, move the cursor to draw the desired shape. Release your mouse-button to end the line and complete the drawing action.
Polygons are shapes composed of multiple, coterminous, line segments that form a solid, two-dimensional, bounded region. Polygons are similar to lines, except that they will always `close` to form a solid shape. To draw a polygon, click "Freehand Polygon" in the "Draw Tools" panel. Then, click on the map at the point where you wish to begin drawing. With your mouse-button still depressed, move the cursor to draw the desired shape. Release your mouse-button to complete the drawing action. A line segment will automatically be added joining the start- and end-points to `close` the polygon.
Repeat the respective procedures outlined above to create multiple points, lines, and polygons on your map.
Sometimes, it is useful to add labels or other notes to the map using text. This is commonly referred to as "annotating" the map. To annotate the map with text, first open the "Draw Tools" panel, and then type the desired text into the box labeled "Text for the Map." Click the "Add Text" button underneath the text you have entered. Then, click anywhere on the map to place your text at that point. Similar to the other draw tools, annotations will "Print to PDF."
The "Undo" and "Redo" buttons allow us to step backwards or forwards through our actions, in order to undo or redo whatever modifications you have just made.
Undo allows you to remove the last symbol you placed on the map with "Draw Tools." To use the undo feature, simply open the "Draw Tools" panel and click the "Undo" button. You may undo multiple steps by clicking the "Undo" button multiple times.
To reverse this action (or 'undo the undo'), it is possible to use Redo. The "Redo" button is located adjacent to the "Undo" button inside the "Draw Tools" panel. Once you have undone an action using the "Undo" button, you may then use the "Redo" button. Similar to the "Undo" button, you may to "Redo" multiple steps by continuing to click the button.
Clear enables you to remove all user-generated points, lines, polygons, and annotations on the map at once. The clear operation also clears the AOI defined by the "Find Area of Interest" tool. To clear all user-generated graphics and annotations, click the "Clear" button inside the "Draw Tools" panel. This operation is analogous to the "Clear Layers" button in the TOC panel, except that it will only clear user-generated graphics, annotations, and the AOI.
Note that if you have not drawn anything on the map using the "Draw Tools," there will be nothing to undo, redo, or clear.
Saving your map is a useful way to share your map or store it for later use. Once you have created a map of interest, you will have two basic options to save and share it. Saving (or 'printing') as a PDF provides you with a digital file that can be viewed, physically printed, emailed, and stored on any digital storage medium (such as your computer hard-drive). Generating a Hyperlink creates a web address (or URL) that can be easily bookmarked in your browser, or copied and pasted. Note that graphics added using the draw tools are not saved via Hyperlink.
This tool allows you to easily save or print your map as an Adobe PDF file. First, click on the "Print" button. A message will appear notifying you know that your PDF file is being created. When your PDF is ready, a new window will open as a popup (note: if you have popups disabled for this website, your popup may be blocked. Most browsers will alert you of blocked popups in the top-right of the browser window).
After the popup is created, you may print your document or save it to the medium of your choice (computer hard-drive, USB drive, cloud storage, etc.). Note that in the popup, you are only viewing the PDF. You must choose to print or save it via the options provided by your browser. In most cases, simply hovering over the PDF with your mouse will bring up a menu of these options. For further help with these options, consult your browser's help documentation.
A convenient way to rapidly share your map may be to generate a hyperlink. This "hyperlink" is analogous to the text you type into the top of your browser (i.e., a URL). To generate a hyperlink for your map, click on the "hyperlink" button. A popup containing your link will appear. Clicking the blue hyperlink will open your generated URL in a new browser window. This link can be bookmarked for later use, or copied-and-pasted in an email to share your map with a colleague. The URL is also displayed as a plain text in the popup.
