Title: "Storage and access of spatial data - what works and what does not"
Location: Huggins Science Hall, Room 336, 12:30 p.m.
Abstract:
Many people save pictures every day without thinking about it. In fact, pictures can be saved in many different formats depending on their intended use. JPG files are the most common, but not the best solution in many cases. Thinking about how to save pictures for the intended use requires the same mindset as storing spatial data. Shapefiles, geodatabases, and spatial databases are all useful ways to store spatial data. Shapefiles are useful for transfer and space, but not useful for large amounts of data. Geodatabases come in three forms, and are useful for large data and performance, but not useful as a file structure format. Databases centralize data storage and promote data consistency, but they are often complex and difficult to design. Accessing the stored spatial data is also an important consideration. Many GIS softwares are available for accessing spatial data, such as ArcMap, MapBox, and QGIS, as well as web-based solutions like HTML, JavaScript, and ArcGIS Online. Viewing spatial data allows users to view and interpret information. With so many options available, it is important that we consider them when we use spatial data to better understand the world around us.
