University of Hawaii Manoa air photo viewer

The University of Hawaii, Manoa Library's Maps, Aerial Photographs, and GIS (MAGIS) program has made over 7,000 air photos of the Hawaiian Islands available online via its Aerial Photographs Viewer. The MAGIS program created basic metadata for each image and georeferenced the flight diagrams and mosaics. The interface uses imagery from Google as a base layer with open source software from Desktop Network Services (DNS).

Users can choose up to six flight paths to view and can access thumbnails of individual images directly in the viewer. High resolution images are also available. For more information, see the library's About Online Aerial Photographs page.

Ranchos of California

During the Spanish colonization of California, three main types of land claims were made by the Spanish crown: missions (for religious use), presidios (for military use), and pueblos (for civilian use). Land outside of these jurisdictions was granted to individuals by the Spanish and eventually, Mexican governments. These individual land grants were known as ranchos in California.

While ranchos are sometimes overlooked during this period in California history, they provide an interesting view of the changes that took place in California during the early 19th century. The Earth Sciences and Map Library, Bancroft Library, The Online Archive of California, and Calisphere all have a wealth of resources that pertain to the ranchos.

The Bancroft Library holds the U.S. District Court's (San Francisco) collection of land grant maps which were used in the Court's Land Case decisions. While access to the original maps is restricted, they are all digitized and available online.

The Earth Sciences & Map Library's collection contains many reproductions of these manuscript maps, as well as other rancho maps not involved in the land case court decisions. More information about the ranchos can be found in the online document "Ranchos of California."

Calisphere has 10 texts and over 300 images related to the California ranchos available for use online.

Project Dataweb image

The United States Bureau of Reclamation has made a broad range of data concerning dams around the United States available online. Project Dataweb is a source for data and information regarding activities related to the Bureau's projects, facilities. The site contains information and data about projects, power plants, and dams. Other resources include interactive maps with facilities listed by state, congressional district, and watershed. A search tool is also available for Project Dataweb. Users can search for a specific location or characteristic (e.g. gravity dams).

From the site's FAQ: "Project Dataweb is the new and greatly expanded version of the 1979 Project Databook. We have Project Databook 1979 information for each project online. The project narratives provide basic facility information, with links to reservoir data, engineering data, and other more specific information. Facilities such as embankment, concrete, and diversion dams have their own pages with expanded information. Many of the projects have online histories from D-5300, the historians in the Technical Service Center. We have been updating each project description by consulting a variety of sources."
