**NEW** Release of LandScan Global 2018
The LandScan Team is pleased to announce that LandScan Global 2018, which is the latest version of this dataset, will be released to the educational community through this portal on Monday, November 25, 2019.
When this newest dataset is posted to the website, all users will be required to go through the process of confirming their educational institution email in order to access any datasets that were previously licensed. However, once confirmed and approved you will have access to your previously licensed datasets as well as the option to download the LandScan Global 2018 dataset.
In the future, users will be able to access any datasets they’ve licensed without the step of reconfirming their information. Although we would have liked to make this the standard for the release of LandScan Global 2018, changes to the system would have further delayed providing the dataset to the user community. We appreciate your patience while we work through this update.
ORNL’s LandScan™ is a community standard for global population distribution data. At approximately 1 km (30″ X 30″) spatial resolution, it represents an ambient population (average over 24 hours) distribution. The database is refreshed annually and released to the broader user community around October.
LandScan™ is now available at no cost to the educational community. The latest LandScan™ dataset available is LandScan Global 2017. Older LandScan Global data sets (LandScan 1998, 2000-2016) are available through site. These data set can be licensed for commercial and other applications through multiple third-party vendors.
LandScan is developed using best available demographic (Census) and geographic data, remote sensing imagery analysis techniques within a multivariate dasymetric modeling framework to disaggregate census counts within an administrative boundary. Since no single population distribution model can account for the differences in spatial data availability, quality, scale, and accuracy as well as the differences in cultural settlement practices, LandScan population distribution is essentially a combination of locally adoptive models that are tailored to match the data conditions and geographical nature of each individual country and region.
