After plotting the points, if some points need to be moved from one location to another, that can be done by clicking on the point and just moving to any desired location.

Note: If the Drop Points option is active for dropping pins, it should be unselected for selecting the plotted pins to open the attribute popup.

After the locations of desired slum locations are plotted and necessary changes are applied, click Save and Publish option to publish the slum locations in the name Slum.

Review and edit the datatable of the slum data

After the user clicks on the Save and Publish option, the Show/Edit Datatable section will open. Attribute fields and attribute values of each location can be edited, updated or deleted in section.

In this option, we can edit the Slum locations and also make the necessary changes in the attribute data. If some user wants to add data to this existing datatable that can be done using the upload datatable option. Download datatable wil help the user to save the necessary information added for the reference.

Here the option for Back is present, which can help users to go back at adding points or Next option to proceed further.

Styling the slum location points

A map will become more meaningful if appropriate icons and colors are used to visualize the spatial features of the map. In IGISMap styling options, Bubble Style and Icon Style are provided for point GIS data.

In Icon Styling, IGISMap provides two more options – Basic and Category styling. For now, let’s make it simple by providing an appropriate pin icon for styling the ATM location points and apply it on the Slums data as follows.

Another style is the categorial style, where users can select the category on the basis of which styling is added to the point data. For example, if the user selects Supply attribute as a categorical option, style is changed to symbol using those items.

Bubble style is used to visualize the data quantitatively based on the numerical fields in the datatable. We can assign the size and color of the bubble for each class of values.

Click on Save Style option to save the Styling options of added points.

It’s done! Now if the user wants to add more points, click on Create more points on the layer option, which will then direct you back to the Add Points section.

If the user wants to create a new layer, select Create New Layer option.

Embed your slum locations map in a website

As the data is created completely and styles appropriately, let’s embed the map of Slums in a website. For this, click the button at the top right, where you will reach the UI to control the sharing of this map.

After the share map components are enabled and disabled as desired, click Next button to proceed to the step for copying the iframe link to embed in a website.

Copy the link from the popup and attach it to your website. Thus the map will be available as interactive as below.

Map habitat locations of endangered animals & keep track of their living

“ Wilderness without wildlife is just scenery”
-Lois Crisler

The International Union for Conservation of Nature (IUCN) states that endangered species are the species of plant or animal that are seriously at the risk of extinction. In this time of data revolution, data analytics plays a huge role in the field of environmental science and atmospheric studies. Keeping the record of the habitat locations of endangered species and observing the variations in their environmental factors will help the authorities to study the causes that threaten the life of these species. These observations can be further useful to prevent global extinction by rehabilitating their populations and restoring habitats. In the article we create point vector data in GIS tool.

GIS technology is an effective tool for managing, analyzing, and visualizing wildlife data to target areas where monitoring and managing is required. GIS technology helps in tracking the migration patterns, mapping biodiversity, and habitat suitability models which provide analysis for animals to locate their habitat locations in suitable environmental conditions.

There are a lot of GIS applications available but IGISMap meets the requirements of the user to perform various GIS operations such as creating point, line, or polygon data; point to polygon conversion; splitting and merging the polygon; conversion between different file formats and much more. Consider a wildlife conservationist who wants to map the habitat locations of endangered animals in India and keep track of their numbers and other environmental factors of their living such as temperature, precipitation, food, water, etc. Create Point Data tool of IGISMap can be used to plot locations and point objects as a point vector data model.

Map habitat locations of endangered species

Users can rely on the Create Point data tool of IGISMap application to plot the habitat locations of endangered animals, like the following.

Final Map of Habitat Locations - Create Point Vector Data — Final Map of Habitat Locations

More information based on these locations can be added as attributes in the datatable. Attribute information in the datatable can be queried using the Proximity Analysis tool of IGISMap. Let’s look into the steps on how the habitat location map can be created and further used for the protection of endangered animals.

To navigate to the IGISMap Create Point Vector Data tool, click the below link

https://map.igismap.com/add-points

Add the Name and Attribute Fields for Your GIS Data

In this section, users can add the name of the data as “Endangered animals”. Next step is to add attribute fields to store other information about the habitat location point. Here lets add Animal, Place and Number as the attribute fields.

The default value added for the field Number can be given as Null. Thus if the attribute value to this field is left blank for any location, Null will be saved. Click Save to add the data information of habitat locations of tigers.

Adding the points of habitat locations of endangered animals

After saving the data information, the adding point option will pop up.The points in the IGISMap can be added in three different ways: (1) Drop points, (2) Search Address, (3) Lat-Long values.

Drop points can add habitat locations of tigers in the form of pins. Zoom to the location on the base map. And add the specific point by left clicking on the mouse and the point gets plotted.

Everytime when a point gets plotted, a popup will open to enter the attribute values in each attribute field of the habitat locations. Click the Submit button to Submit and save the attribute entries. You can choose to delete the point you plotted by clicking the Delete Point button. Else you can click Skip to close the popup. You can disable the default opening of this popup using the toggle button.

Next way of adding point data is using the Search Address option, for example, search uttarakhand in the search box and click the plot option.

Third option is using the Latitude Longitude values to add the habitat location of the endangered animals in Karnataka. Add the latitude and longitude value in the boxes and the point gets added to the base map.

Enter Latitude and Longitude - Create Point Vector Data — Enter Coordinate of the Location

After plotting the points, if some points need to be shifted/moved from one location to another that can be done by clicking on the point and just moving to any desired location.

Note: If the Drop Points option is active for dropping pins, it should be unselected for selecting the plotted pins to open the attribute popup.

After making all the changes, click on the Save and Publish button to publish the GIS data of habitat locations.

Review and Edit the Datatable of the Slum Data

After the user clicks on the Save and Publish option, the Show/Edit Datatable section opens. Attribute fields and attribute values of each location can be edited, updated or deleted in section.

Option to update the data table as bulk is available in this section. Here the whole datatable can be downloaded in Excel format using Download Datatable button. And to make the changes outside IGISMap, then upload the edited/updated spreadsheet file using Upload Datatable button. Further, integrate with the same point data of habitat locations.

Here the Back button is present for going back to the Add Points section to add more points or click Next option to proceed further.

Styling The Habitat Location Points Of Endangered Species

In this section, users can use different styling options for the pin. The Basic Icon styling options are shown below, where the user can select any of the styles.

Another style is the Category Icon styling, where users can select the category on the basis of which styling is added to the point data. For example, if the user selects Supply attribute as a categorical option, style is changed to symbol using those items.

Bubble style is used to visualize the data quantitatively based on the numerical fields in the datatable. We can assign the size and color of the bubble for each class of values.

It’s done! Now if the user wants to add more points, click on Create more points on the layer option. If the user wants to create a new layer, select Create New Layer option.

After the point GIS data of habitat location is published in the name Endangered animals, More option beside the data provides list of other features. They can be used to adding more points, show the legend in the map, editing the style and more.

Embedding Map In Your Website

As the data is created completely and styled appropriately, let’s embed the map of habitat locations on a website. For this, click the button at the top right, where you will reach the UI to control the sharing of this map.

After the share map components are enabled and disabled as desired. Click Next button to proceed to the step for copying the iframe link to embed in a website.
