Application of Adobe Illustrator auxiliary software for improving ArcGIS thematic mapping in urban geological surveys

Thematic mapping in urban geological surveys is based on huge amounts of data, and such mapping is important as urban areas expand and intensify. To improve the quality of geological maps and to develop new ways of expressing geological data, this study examines vector drawing software as a professional drawing tool, and discusses the techniques and methods involved in producing thematic maps based on geological data. The use of Adobe Illustrator in conjunction with ArcGIS software not only retains the accuracy of spatial data but also provides geological maps with a variety of functionalities and improves the visual properties of such maps.
