CONTEXT and CHALLENGES
Hybrid visualization between maps and imagery
![Page 3: Color and Texture Interpolation between Imagery and Vector Data](https://reader030.vdocument.in/reader030/viewer/2022020301/58e8d1be1a28abb3398b5741/html5/thumbnails/3.jpg)

Long term purpose
Modelisation of the cartographic style
Style navigation between cartographic representations
→ Design method to create Cartographic Continuum
Topographic Map Imagery
![Page 4: Color and Texture Interpolation between Imagery and Vector Data](https://reader030.vdocument.in/reader030/viewer/2022020301/58e8d1be1a28abb3398b5741/html5/thumbnails/4.jpg)
4C. Hoarau, S. Christophe GeoVIS – ISPRS GeoSpatial Week
Design challenges
Create efficient hybrid visualizations
→ Avoid global image blending by transparency
→ Understand the perception of conveyed information
→ Create smooth transition to help cognitive tasks(such as feature recognition, territory comprehension, etc.)

6C. Hoarau, S. Christophe GeoVIS – ISPRS GeoSpatial Week
Abstract representation of the real world
“All maps are abstractions of the reality”
[Robinson et Al. 95]
Information is identified, interpreted, structured and hierarchised
Abstraction steps in the cartographic process
Data selection
Data generalization
Data symbolization
Topographic map perception
![Page 7: Color and Texture Interpolation between Imagery and Vector Data](https://reader030.vdocument.in/reader030/viewer/2022020301/58e8d1be1a28abb3398b5741/html5/thumbnails/7.jpg)
7C. Hoarau, S. Christophe GeoVIS – ISPRS GeoSpatial Week
Imagery perception
Realistic representation from the sky
Photo-realism effect
Automated acquisition
Continuous representation
Non encoded information
Increased credibility in a “ground truth”
Difficult to interpret as “raw” data
![Page 8: Color and Texture Interpolation between Imagery and Vector Data](https://reader030.vdocument.in/reader030/viewer/2022020301/58e8d1be1a28abb3398b5741/html5/thumbnails/8.jpg)
