Search Address option opens a search address box, where you can enter an address and choose the right location address from the dropdown and click the Plot button to plot a point on that location.

Lat Lon Values will open two boxes to enter latitude and longitude values of the location you want to plot, Plot Location button in this option will plot a pin at the location you have entered.

Also, a popup will open for entering attribute values in each attribute field for that telephone pole locations when a point is plotting. Click the Submit button to submit the save the attribute entries. You can choose to delete the point you plotted by clicking the Delete Point button. You can disable the default opening of this popup using the toggle button.

But we can open this popup anytime while plotting, by simply clicking on an existing pin.

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 plotting every desired slum locations for our data, click the Save and Publish button to publish your data in the map.

Review and edit the datatable

After publishing Telephone poles, Show/Edit Datatable section will be opened. Here you can edit the attribute values entered for each point location after clicking button in the datatable along each row in the datatable. You can also choose to delete a point by clicking button.

Options to edit or delete the attribute fields are also available in this step along with the option to add new attribute fields to this data. If you thought of adding more points to the data of ATM Locations, select the Back button to go to the Add Points section, where you can add more points and make changes to the already published data.

Option to update the data table as bulk is available in this section. Where the whole data table can be downloaded in Excel format using Download Datatable button.
