Overview:

  • This tool is useful if the user wants to measure an area in the map.

f)    Print

·         Arrange a view on the map as desired and turn on/off data layers as desired.

·         Activate the Print tool by clicking it.

·         A pop-up will appear where the user needs to enter Title and Comments if any on the displayed output.

·         The scale chosen determines the size of the bounding box which will encompass the map’s print boundary. The bounding box can be dragged as required.

·         The paper size, DPI, and orientation can also be set as desired, then Click Print.

g)    Find Nearest Road

·         Toggle on building, road, and containment layers with an underlying base layer.

·         Activate the Find Nearest Road tool.

·         Click any point on the map. The nearest Road will be shown with a Marker. Use the Info tool to get information about the Nearest Road, if needed. Use the Measure Distance tool to get distance information between clicked location and the nearest road, if needed.

·         Click the Remove Markers tool to get rid of markers from the map.

Overview 

  • User can find the nearest road from the desired location.

h)    Find Buildings Connected to Containment

·         Activate the tool. 

·         Select the containment for which user want to search the building for the building found is outlined.

·         Click the ‘Remove Markers’ tool to get rid of markers from the map.

·         If the user wants to navigate to a specific location (E.g., specific road, specific building based on Holding No.) in the map, search tools are extremely beneficial.

  • The search tool provides a criterion to search for a specific building based on criteria such as BIN, Holding No, Tax Code, Landmarks, or Road code. 

 

18.3.2 Layers TAB

The Layers TAB in IMIS provides a map-based interface where users can visualize information from various modules and submodules. It also allows users to select their preferred base layer (e.g., Google, Bing, OSM) for viewing the map. In the 'Overlays' section of the Layers tab, users can choose specific layers to display on the map. These layers represent data maintained in the various submodules and modules of IMIS and the styles present in the individual dropdowns are based on the attribute information maintained in their respective sub modules. For example, if a user selects the ‘Buildings’ layer, the attributes of the ‘Buildings’ sub module will be listed in the dropdown, and the user can select the attribute they want to visualize in the map. User can also select Summarized Grids layer (0.5 km grid) to view the spatial status of the Municipality based on specific criteria, e.g., No. of Buildings, Wards, etc.

Note: The list of data layers available to a user is government by their login credentials.

·         Click the nearby checkbox to toggle ON/OFF a specific data layer.

Figure 18- 16 Visualization of different Layers based on two different criteria

Overview:

·         If a data layer has multiple visualization options, a drop-down list will appear.

  • Change the options in the list to change visualization based on different attributes of the data layer.

18.3.3 Tools TAB

Tools TAB enlists different specialized tools developed specifically to cater to the needs of various users of IMIS. There are altogether 20 different tools categorized under different headings such as Service Delivery Tools, General Tools, Data Export Tools, Decision Tools, and Summary Information. The availability of tools will be governed by the login credentials of the user.
