U.S. Department of Agriculture (USDA) Pomological Watercolor Collection

The USDA Pomological Watercolor Collection is a collection of original watercolors, lithographs, and photographs documenting fruit and nut varieties developed by growers, including USDA plant explorers, around the turn of the 20th century. Technically accurate paintings were used to create lithographs illustrating USDA bulletins, yearbooks, and other series distributed to growers and gardeners across America.

U.S. Forest Service National Insect and Disease Risk Maps

The National Insect and Disease Risk Maps (NDRM) assess the potential hazard for tree mortality due to major forest insects and diseases across the United States. The NIDRM can summarize landscape-level patterns of potential insect and disease activity. This could help prioritize investment for areas where both hazard is significant and effective treatment can be efficiently implemented. The NIDRM page hosts many up to date supporting documents that describe this project. Numerous Zip files with downloadable GIS raster data (ArcINFO GRID format) and downloadable tabular summaries (MS Excel format) are hosted on the site.

Sample of Mandan, North Dakota Aerial Image Dataset

Originally produced by the Farm Security Administration, these are georeferenced aerial images from Morton County, North Dakota. Historic print images housed at the Mandan, North Dakota ARS Long-Term Agricultural Research facility were digitized, georeferenced, and processed for use in both professional and consumer level GIS applications, or in photo-editing applications. The original images were produced by the Farm Security Administration to monitor government compliance for farm land agreements. Current applications include assessing land use change over time with regard to erosion, land cover, and natural and man-made structures. Not for use in high precision applications.
