Highlighting Policy Maps using Effects | Esri India

Policy maps are essential tools for bridging the spatial data gap crucial for policymaking, especially in countries like India. These maps encompass key themes such as population density, demographics, building density in major cities, and transportation networks.

To enhance the effectiveness of these maps, advanced visualization techniques available in ArcGIS Online can be employed. This blog discusses applying these techniques to a policy map for Bengaluru, focusing specifically on percentage impervious surface data aggregated at the ward level from sources like the Ulandsat Global Man-made Impervious Surface (GMIS) dataset.










Highlighting Policy Maps Using Effects

Thematic maps can be significantly enhanced through techniques like Effects, Blending, and Filtering. The latest updates to ArcGIS Online introduce the Effects capability, similar to features found in image editing software. These effects can be applied to entire layers or specific features within layers, allowing for dynamic adjustments that update in real-time.

  • Effects Panel: Users can activate the Effects panel by selecting a layer and enabling the Effects button. Options such as Drop Shadow, Bloom, and Blur can be adjusted via sliders or input values to customize visual properties.
  • Feature-Specific Effects: For more targeted emphasis, effects can be applied based on specific data attributes using expressions. This allows users to highlight features that meet certain criteria, enhancing the narrative conveyed by the map.
























           









 
Map Blending

Another powerful technique discussed in the blog is Map Blending, which is applicable to both vector data and thematic rasters. Blend modes control how layers interact visually, influencing color blending and texture display between layers.

  • Blend Modes: By grouping layers and applying blend modes (e.g., Destination In, Destination Atop), users can create nuanced visualizations that emphasize thematic patterns while maintaining clarity and context.
  • Enhancing Blended Maps: After blending layers, further effects can be applied to refine the visual presentation. Techniques such as Invert, Drop Shadow, and adjustments to Brightness & Contrast help focus attention on specific areas of interest within the map.
