AUTHORS: Jenna Ducharme, RPS ASA

ABSTRACT: Presenting spatial information through maps and figures is a common task performed by the GIS community. Often, there is a need to create dozens of maps to accurately relay information on the topic of interest. This presentation demonstrates an approach to automating the task of creating maps in ArcGIS using Python. Following the generation of a template map in ArcGIS, a python script can be used to manipulate the data sources for each layer in the template, the titles and text, map extent, definition queries on data layers, and the locations of graphical elements. This approach allows the user to export hundreds of maps and change elements in each map without opening ArcGIS, and with limited manual effort. Automating map generation reduces human error and increases efficiency. A demonstration of the capabilities of map generation using Python will be held during this presentation, as well a high-level description of the code written to perform such tasks. Finally, other advantages of automated map generation will be highlighted, including the ability to use several standalone maps to create videos (AVIs), to show a time series of an oil spill over a number of hours.
