Selected Presentations

Using Multiprocessing in Python to Decrease Map Production Time
  • Presentation Type: Oral Presentation
  • Date: 6/28/2016
  • Abstract: The National Drought Mitigation Center produces hundreds of maps on a weekly basis for the U.S. Drought Monitor and other drought related products. These maps are mainly generated using a combination of Python and ArcGIS. Previously this process has taken several hours to run from start to finish. Multiprocessing has been implemented in order to be able to create and export multiple maps at the same time. Doing so has greatly decreased the necessary processing time.

Using ArcGIS 10 to Estimate the U.S. Population Affected by Drought
  • Presentation Type: Oral Presentation
  • Date: 7/22/2015
  • Abstract: Drought has become an increasingly serious problem for heavily populated urban areas, and as a result there have been numerous requests for estimates of the number of people affected. The U.S. Drought Monitor production process uses ArcGIS 10 and Python and because of this, a methodology for creating these population estimates was able to be easily implemented as part of the production process. This has also made it possible to deliver these estimates to the public in a timely manner.

Improvements to the U.S. Drought Monitor Production Process
  • Presentation Type: Oral Presentation
  • Date: 4/14/2015
  • Abstract: The U.S. Drought Monitor is produced by a joint effort of four agencies including the National Drought Mitigation Center. The NDMC is responsible for the production of a series of maps, statistics and other datasets on a weekly basis. This process was updated to a series of Python scripts in 2013 in order to increase production speed and efficiency. After a year of running the new process, a number of improvements were deemed necessary. The goal is to reduce production time, reduce the required number of input files, and increase the flexibility of the process to allow for the creation of more maps and datasets.
