The Map page is where you can visualize point clouds, rasters, and vector data. You have access to the datasets in your catalog, but also have the option to upload local and/or web data, save your workspace as a scene, and build interactive stories. Note that while on this page, the left navigation menu will collapse into an icon-only view.
Map Page User Interface¶
(1) Map Workbench: A secondary left-hand navigation menu for the Map page. It can be used to search through data, add data to the map, and select which layers you want to visualize in your scene.
(2) Location Search Bar: Allows you to type in the name of a country, city, street name, and coordinates. Once you click on one of the search results, the map will zoom to the extent of the searched location.
(3) Add Data Button: Brings you to a window that allows you to access your catalog, which includes all of your datasets. You have the ability to add your data in the form of Point Clouds, Rasters, Vectors, and upload local or web data under My Data. Web Services can be used to add data from other sources, such as US Government Services.
(4) My Data Button: Brings you to the My Data window, where you can add local data via drag and drop or click on Add Local Data to select the file(s). You can also choose to Add Web Data using geospatial web services and servers.
(5) Scene Name: Displays the name of the current scene, if any. An asterisk indicates that the scene is not saved. For more information, refer to the Scenes page in the product manual.
(6) Markups: If markups are generated, each markup type will be grouped under a layer and can be toggled and/or zoomed to.
(7) Layers: The number within the brackets indicates how many layers have been added to the map, and can be enabled or disabled for visualization. In addition, clicking the expand arrow on each layer will allow you to see what options are available, such as zooming to the extent of that layer.
Please note: If your raster layer does not have the ‘Zoom To Extent’ option, it’s possible that it was created before this feature was enabled. In order to access it, the raster will need to be reuploaded/recreated.
(8) Remove All Option: Removes all of the Layers loaded in the map with one simple click.
(9) Markup Editor: Opens a panel in which you can create and/or delete markups on your map view. These markups can also be downloaded.
(10) Story Editor: Allows you to create a visual and interactive narrative using the map to tell a story located anywhere in the world.
(11) Map View: Allows you to toggle between different types of 3D or 2D maps, and a selection of basemaps. There are two 3D map options available: 3D Terrain and 3D Smooth.
The 3D Terrain option uses a built-in DEM, whereas 3D Smooth uses a flat ground model with the globe at 0 elevation. The datasets used to build the 3D Terrain model range from 1m to 20m DEMs, and therefore some areas will provide more accurate terrain than others. Please see example images below of 3D Terrain (left) and 3D Smooth (right).
(12) Share/Print Button: Gives you two options: first to share the URL so that anyone can access the map, and second to print the map. There are also advanced options in an expandable menu within the share/print menu to embed the map into an HTML code.
(13) Save: Allows you to save your workspace as a scene using the Save Scene As option. If a scene is already open, you can update your layers with the Save Scene option, or edit the name with the Rename option.
(14) 3D Navigation Tool: Use this interactive tool with your mouse to change the 3D perspective on your dataset.
(15) Zoom Tool: Use your mouse cursor to zoom in, reset zoom, or zoom out. If no data is loaded, the button will zoom to the extent of North America. If you have data loaded, the button will zoom to the extent of the visible layers.
(16) Center Map at Current Location: Centers the map extent around your current location. This function accesses your computer’s geolocation information, so ensure it’s enabled.
(17) Side-by-Side Comparison Tool: Enables a visual comparison between two different datasets using a slider that can be dragged left and right across the map.
(18) Measurement Tool: Allows you to click two or more points to make linear distance and area measurements. Linear distances are provided in meters and kilometers. Area measurements are provided in meters squared.
(19) Latitude/Longitude/Elevation: Displays the XYZ coordinates of the map data where your mouse cursor is hovering.
(20) Scale: Displays map scale in meters.
You can click anywhere on the map to see the Feature Information window, which displays information contained within the layer data. If there is no data loaded, it will show the coordinates of the location that was clicked on the map. In the example below, the Land Surface Forms layer data in South America is loaded into the map. A point is clicked somewhere in Venezuela and is found to be in the Coastal Plains class in the layer, along with other feature information.
At the bottom of the Feature Information window, to the right of the coordinates, there is a Location Marker icon. If you click on it, the Location Marker icon will turn blue (enabled) and a marker will be placed on the map at the selected coordinates.
Once this feature is enabled, it will remain enabled and place a Location Marker anywhere you click on the map. Only one can be placed on the map at a time, and clicking on a new location will move it to the selected location. To disable the Location Marker, simply click on the icon again in the Feature Information window and it will turn white to indicate that it has been disabled.
There is also an option to download the feature information table. You can do this by clicking Download this Table in the Feature Information window.
Adding Data within the Map Page¶
You can be brought to the Map page one of three ways:
- Click Map in the left navigation panel, which will open a blank map page.
- To view a particular dataset, go into the Dataset Overview and click the blue extent in the map preview.
- To view a particular scene, go to the Scenes page and select the View Scene icon under the Actions column.
If you enter the Map page before selecting a dataset, the map workbench to the left of the map will prompt you to add data. This workbench can also be collapsed using the Collapse Workbench arrow to the right of the Search for locations search bar.
The Add Data button in the map’s workbench brings you to a window that allows you to access your catalog. Your datasets will be listed by type under the associated tab. Note that the Rasters tab includes your uploaded raster datasets and two types of additional raster products if created: Hillshade, and the Topo Change output named Change 2D Color. Additionally, this window gives you the ability to add local or web data under My Data, and provides additional sources under Web Services.
Please note: Rasters are draped over the basemap terrain. To learn more about the types of basemaps available, refer to Map View under the Map Page User Interface.
To add point cloud data, click on the Point Clouds tab if not already selected. Click on a dataset to expand the folder and list the available classes. For point clouds, both the source classification and the reclassification are visible if applicable. Plus signs indicate which layers can be added to the Map page, and minus signs indicate loaded layers that can be removed.
The above example shows the Catalonia, Spain (Survey 2) dataset where all of the layers except Before Classification have been selected.
Click Done when you’ve completed your data selection, and your data will appear on the map with the selected layers listed in the workbench to the left.
This button brings you to the My Data tab in the Add Data window.
In the My Data tab, you can add local data via drag and drop or click on Add Local Data. Additionally, you can choose to Add Web Data using geospatial web services and servers.
If you want to add local data using the button, the Add local file window appears. You are given the option to select the file type, and can click the drop-down menu to view the list of accepted types. However, it is recommended to allow the tool to auto-detect the file type and you can skip this selection. Please refer to the image below.
You can upload shapefiles (.shp), but the shapefile and associated files need to be zipped together, but not zipped as a folder — rather as multiple files in a zip file. You can allow Enview Explore to auto-detect the zipped shapefile, or you can select Other (use conversion service).
Once you select the zipped shapefile, you will be asked to use a conversion tool. Click Yes. The zipped file may not appear as a supported file type when you’re browsing to add data to your map. If you encounter this issue, please ensure you change the file extension to All files when loading data.
Please note: GeoJSON and CSV files need to be in EPSG 4326 or 3857.
If you would like to add web data, click on the Add Web Data option and the relevant page will open. Similar to the Add local file window, you can skip Step 1 or you can manually select the file type or which server you would like to add from the web. In Step 2, please enter the URL of the data file or web service.
There are additional 3D terrain settings available for visualization if you have 3D Terrain enabled under Maps. The Terrain Settings available for visualization are No Shading, Elevation, Slope, Aspect, Hillshade, and the ability to Enable Contour Lines.
Enview Explore can render 3D terrain on a global scale, and you can customize it by using the Terrain Settings module. To access it, click on the Map button, then select Terrain Settings.
Please note: The Terrain Settings visualization is a feature that must be toggled manually for the current user. If the current user (you) would like to share the scene, other users will only receive the location of the scene and will need to manually enable Terrain Settings to visualize on their end.
The No Shading setting (the default setting) is clear of any Terrain Settings, and simply shows the data prior to enabling any Terrain Settings.
The Elevation setting includes the ability to select the Time of Day from 1:00 to 24:00, and to colorize the elevation with the color ramp.
The Slope setting includes the ability to select the Time of Day from 1:00 to 24:00, and includes default coloring to display areas of varying slope values. Slope describes the steepness or degree of incline of a surface. Cooler colors such as blue have less slope, and warmer colors such as red have a larger slope value.
The Aspect setting includes the ability to select the Time of Day from 1:00 to 24:00, and includes default coloring to display the aspect of the surface. Aspect is the orientation of Slope, and measured clockwise from 0 to 360 degrees, with 0 degrees representing north-facing (dark purple), 90 degrees east-facing (yellow), 180 degrees south-facing (orange), and 270 degrees west-facing (red).
The Hillshade setting includes the ability to select the Time of Day from 1:00 to 24:00. This feature is a grayscale 3D layer of the surface that takes the relative position of the sun into consideration for the shading. The Time of Day setting determines the sun’s altitude and azimuth in the sky, affecting the hillshade visualization.
The Enable Contour Lines setting is available for every Terrain Setting. Contour lines mark areas of equal elevation above a certain level on a map. Once the contour lines feature is enabled, there are options to adjust the Contour Line Spacing if you’d like more or less frequency of contour lines, Contour Line Width to make the contour lines thinner or thicker, and the ability to adjust the color of the contour lines.
Click on the Measurement Tool icon to start measuring the distance between two points or obtaining the area in a user-created shape.
Once you click the icon, a Measure Tool window will appear to let you know that you can start clicking to add points to the map for distance measurement.
You can create two points to measure a linear distance, or you can click multiple points to create and measure an area.
Once you have finished clicking two or more points, click Done.
Click on the side-by-side comparison tool located on the right side of the Map page to start a comparison between two different datasets.
Please note: This is a 2D data feature only.
Expand the layer options, and click on Split on the two layers of interest. This will populate more options for opacity, and whether you want that particular dataset to be on the left side, right side, or on both sides of the comparison.
In this example, we chose a 60% opacity for both datasets, and placed one on the left side of the slider and the other on the right.
Drag the slider left and right to adjust the views and compare the results.
Markups are used to manually add areas of interest to your map, which can then be saved as a part of your scene and/or downloaded. In order to generate new markups, click on the Markup Editor icon at the top of the Map page and you will see tabs along the top of the panel for various markup types. Currently the markup editor supports points, lines, and polygons.
To begin, select the markup type at the top of the editor and click Create. Your cursor will change and allow you to click anywhere on the map to create a feature, either before or after adding a Title and/or Description. When creating point markups you may also enter your own coordinates, after which the marker location can be confirmed with the Validate Coordinates button. Once the form is complete, click Save.
All of your generated markups will be listed in the Markup Editor panel. Options to Delete All or Download All as a .kml are located at the top. Selecting the Title will expand the box, displaying the Description, coordinates, and the options to Delete or Download the individual feature.
You may also select the markup in the map view to bring up the Feature Information box. It displays the markup type, Title, Description, coordinates, and the option to download the table as a .csv or .json.
Please note: In this section, the term ‘scenes’ refers strictly to the Story Editor interface.
The building blocks of a story are scenes. Scenes are created by adding data and framing your map how you would like your audience to see it, and then adding narrative text. You can add multiple scenes in a story using the Story Editor tool to create a visual and interactive narrative. All data types can be displayed in stories, including markups. The workflow for story generation and sharing is depicted below.
First, load in layers of interest that you would like to add to your story. A story can move from one location to another, and can be as simple as showing one layer with text, to comparing two layers using the side-by-side comparison tool, and more.
In our example, we will be using open source data from US Government Services. We first loaded in data on Topographic position and Bioclimates, and later we will add data on 2019 Fires.
The first story we want to show is the correlation between Topographic position and Bioclimates in California, so we enabled those two layers and also enabled the side-by-side comparison tool.
To start creating a story, click the Story Editor icon located in the top right corner of the map.
A tertiary right-hand navigation menu will appear for story editing.
Once you’ve framed the map the way you’d like your audience to see it, click the Capture Scene button in the Story Editor menu.
A story editing window will appear, where you can enter in a title and content for that particular map.
Once you’re done editing the narrative, click Save. You should then see the story added to your menu under Scenes.
To exit the editing menu, click the Story Editor icon again.
Now you want to add another scene to your story. Grabbing the 2019 fire data from the US Government Services, keep the Topographic Position layer enabled, and disable the Bioclimates layer. Ensure the side-by-side comparison tool is enabled. This time, you have one layer displayed on both sides of the slider and another layer displayed only on the right.
To add this scene to the story, click on the Story Editor icon again.
You will still see the previous story that you made, and now you want to capture this scene to add to the story. Click on the Capture Scene button for the story editing window to appear. You can add a title and content for this scene.
After clicking Save, you will see that there are now multiple scenes in the story.
You can use the 3 dotted icon to move one scene above or below another scene; this adjusts which scenes show up first in the story starting from the top.
Click the Story Editor icon to exit the story editor and return to the map.
If you want to play your story, go back into the Story Editor and click on the Play Story button. It will begin playing your story scenes in the order that you have placed them in the story editor menu. This works by bringing you to the spot where the map content and text narrative for that scene is.
Once your story starts playing, you will see a new window appear near the bottom of your map with the title and narration of each scene. You can click the left and right arrows to move from one scene to the next.
If you want to share your story, click on the Share/Print icon located at the top-right corner of the Map page. There, you can copy the URL to share with anyone, or embed the code into an HTML page under Advanced options. To view the shared URL, individuals will be required to create an account.
