Angela Gibson, GIS Specialist, recently attended the Annual
The Indiana GIS Conference included workshops centered on changes in the 2010 U.S. Census, the updated National Hydrology dataset, digital elevation and digital surface models, and the Public Land Survey System tie-card project. Shorter sessions were offered for a variety of subjects, such as the new oblique aerial photography, library-based interdisciplinary GIS, development of the GIS Atlas for
So exactly what is oblique photography? Oblique is the technical term used to describe an aerial photograph that is taken at an angle. This means that a feature such as a house, a building or an overpass can be viewed in its entirety. This does not just mean the user can see one side of the building; rather, the image can be rotated to view the front door, back door, and both sides as well. This view is familiar to most users and provides for almost instant 3-D modeling. An oblique image can also be geo-referenced, so that GIS data such as streets, hydrology, and parcels can by layered over it.
As always, the Annual Indiana GIS Conference was a hotbed of new ideas with conversations about trends that are occurring in the GIS world. There was also exciting news about powerful new resources for GIS professionals and persons who use GIS media tools. This exciting new information about available GIS datasets and their applications will prove to be very useful for the students and faculty who use the Geospatial Center & Map Collection, located in Bracken Library on the second floor.
