description Dana Tomlin Overview
Dana Tomlin is an American geographer and GIS scholar known for developing map algebra, a formal framework for manipulating raster-based geographic data. He presented the approach systematically in Geographic Information Systems and Cartographic Modeling, published in 1990. Map algebra organizes local, focal, zonal, and global operations on map layers and remains foundational for students, researchers, and practitioners performing raster analysis in GIS software.
help Dana Tomlin FAQ
What is Dana Tomlin famous for in the field of GIS?
Dana Tomlin is an American geographer renowned for developing 'map algebra,' a formal framework for manipulating raster-based geographic data. His innovation allows users to perform complex spatial analysis on gridded data layers.
What major book did Dana Tomlin publish?
Tomlin presented his systematic approach to spatial data in the 1990 book 'Geographic Information Systems and Cartographic Modeling.' This text remains a foundational read in modern GIS studies.
Where does Dana Tomlin teach?
Tomlin has spent his academic career teaching at the University of Pennsylvania. He holds a position in the landscape architecture and regional planning departments.
What is cartographic modeling in GIS?
Cartographic modeling, as defined by Dana Tomlin, is the process of using map algebra to solve spatial problems. It relies on overlaying and mathematically combining different raster layers to create new geographic information.
