GIS Data Frequently Asked Questions
The BIGGEST hurdle of any GIS project is obtaining data. Data can be very expensive and more often in various formats, types, projections. Some figures I have heard run the GIS project timeline with 75 % of the time used for data collection & preparation.
Where can I obtain GIS Data?
Because most all information has a geographical location we can display the location within a map. For example, customer addresess can be displayed by address, zipcode, state or other geographic representation. However, simple locating an address without background such as streets, zipcode outlines, ocean, etc needs some orientation. Fortunately, there is a vast supply of GIS data basemap material avaiable. However, free data comes with problems such as projections, scale and even languages. The campus software license fortunately is accompanied with many gigabytes of GIS data including the ESRI Digital Library
Where can I obtain Local GIS Data?
GIS data searching (often referfed to as mining) is a big task. The GIS Services provided by the Libraries of The Claremont Colleges is prepared to assist you in your search. However, we have data (geodatabase) for the local area that can be made avaiable to you such as demographic, political, business, crime data and surface layers (dem). This data is regularly used in the free GIS workshops regulalrly scheduled in the Keck Lab.
