GIS Visualization

GIS is a visualization that displays the data in Geographical Information System. It uses data that is attached to a unique location. GIS is a computer-based tool used to store, visualize, and interpret geographic data that identifies the geographic location of features with the help of Latitude and Longitude data.

In the example below, GIS is created with “Latitude and Longitude” as columns, to analyse Global data.

To create a GIS

• Right-click on the ‘Component(s)’ column > Select View> Change>GIS.
  

Refer here to learn more about creating a visualization.

The following figure shows the resulting GIS:

Latitude #

You can specify the column to be displayed as Latitude in GIS.

To change the column:

1. Click on the icon to remove the existing column.

2. Drag the desired column from the Data Panel and drop it onto the Visualizations Panel’s “Latitude” section.

Note: You can also type the column name in the Data Panel to quickly find it.

Longitude #

Here, you can specify the column to be displayed as Longitude in GIS.

To change the column:

1. Click on the icon to remove the existing column.

2. Drag the desired column from the Data Panel and drop it onto the Visualizations Panel’s “Longitude” section.

Note: You can also type the column name in the Data Panel to quickly find it.

LatLong Or LangLat #

Here you can provide column where it contains geographic coordinates in the form of latitude and longitude. You drag and drop the column from your dataset in LatLong or LongLat data configuration.

Latitude, Longitude and Latlong or Longlat support for Multivalued Fields in GIS #

Gathr Analytics supports multi-value inputs for latitude, Longitude and Latlong or Longlat fields allowing you to input multiple geographic coordinates from your data set.

These formats represented in the illustration shows multi value support for multiple sets of coordinates.

Entity #

It denotes individual geographic entities such as points, lines, or polygons. You can drag and drop appropriate column from your dataset.

Entity Movement #

Entity movement refers to the dynamic tracking and visualization of the paths or trajectories of geographical entites (such as vehicles, animals, or weather systems) over time, illustrating their changes in location on the map.

• Data Configuration

To plot the entity movement, input Latitude, Logitude, Entity and Timestamp fields in data configuration tab, ensuring with relevant columns present in your data.

• Visual Configuration

In Visual Configuration tab, you can configure Entity Movement by enabling the legend with the toggle switch. To provide view controls to the app user toggle on the settings for entity movement and entity legend.

Let’s understand entity movement with the following illustration:

We have sample data containing location information for two vehicles (Vehicle1 & Vehicle 2) between January 1st, 2024 and April 30, 2024.

To plot entity movement visualizations for Vehicle 1 and Vehicle 2, drag and drop relavant columns available in your data to the latitude, longitude, entity and timestamp columns available in Data Configuration tab as shown in the image below.

Additionally, there is a short video created to show entity movement.

Timestamp #

It defines the geometric shape of geographic features, such as polygons for areas or lines for routes.

Visual Configuration #

• Click the icon for visual configuration settings.

GIS Settings #

GIS settings allows users to configure features such as Heat Maps, Markers, Labels to customize visual representations of geagraphical data on maps.

To configure, click on GIS Setting to expand configuration options.

• Heat Map lets you customize the representation of data in which values are represented by colors.

• To turn Heat Map on or off, select the toggle switch next to Heat Map.

• Marker settings toggles the display of specific points or locations on the map.

• To turn Marker on or off, select the toggle switch next to Marker.

• Label setting toggles the visibility of text labels associated with map features of data points.

• To turn Label on or off, select the toggle switch next to Label.

View Controls #

Entity Movement stimulates movement of individual entities on a map. We can denote an movement of an entity from Distance Unit, Distance Decimal Places, toggle to Show Time and Show Average Speed.

Geoshape #

Under Geoshape visual configuration you have following settings:

• Distance Unit: It specifies the unit of measurement for distances within the geoshape, such as kilometers, meters, or miles.
• Distance Decimal Places: It determines the number of decimal places displayed in distance measurements, offering precision control.
• Coordinate Precision: It sets the level of detail for coordinates defining the geoshape, affecting accuracy and rendering smoothness.
• Radius Limit: It establishes a maximum allowable radius for circular geoshapes, limiting their size within the visualization.
• Length limit: It defines the maximum permissible length for line-shaped geoshapes, restricting their extent in the visualization.
• Breadth limit: It specifies the maximum width for polygon geoshapes, constraining their breadth within the visualization.
