Step 1: Data options

The first step is to determine which data sets you want to display and distribute. This process will generate a list of your initial design decisions for the RDMS staff. Please select from the data sources below.

RDMS-supplied data

RDMS-supplied data represents data available from RDMS. These include common data sets in the public domain, data from national and international data consortia to which RDMS has access, and data provided to UD for educational purposes. RDMS staff can help you navigate and explore these collections.

• ESRI Data and Maps 2006

  Provided by ESRI for educational use only. A 10-Gigabyte collection of vector data (e.g., boundaries, roads, waterways, elevation contours) and satellite imagery at all geographic levels. [http://maps.rdms.udel.edu/gis/esridata.html]

• Delaware Basemap Data

  Commonly used spatial data sets for Delaware, including the Delaware Spatial Data Framework available via the Delaware DataMIL. [http://maps.rdms.udel.edu/gis/debasemap.html]

• Census

  RDMS is a coordinating member of the US Census State Data Center program. We provide access to census data from 1790 to the present in several ways. You can use interactive web sites such as our Delaware Census 2000 web site or the U.S. Census Bureau's American FactFinder. Additional resources include several networked data consortia collections and use of data extraction software in the RDMS Research Computing Lab (002C Smith Hall).

• Delaware Imagery

  Aerial and satellite imagery for Delaware. The RDMS Delaware imagery inventory is at http://maps.rdms.udel.edu/gis/delorthos.html.

• Additional Map Serviecs

  You can integrate many existing map services into your web site. Commonly used map services are accessible from ESRI's Geography Network, the U.S. Geological Survey, and the Delaware DataMIL.

User-supplied data

User-supplied data may include tabular data as well as spatial data. Examples might include GPS coordinates of locations, tables of numerical and text information that you've created, and data that you have acquired with the legal right to use it on a web site.

You may supply RDMS with your own spatial data sets (points, lines, polygons, rasters, TINs) as long as the data is in a format supported by ESRI products. Your data should have the same geographic extent and coordinate system as the other data sets in your site.

You may supply your own tabular data.
Tabular data may be linked to spatial data sets by a common field or may contain their own location information (e.g., mailing addresses.) For example, a spreadsheet of US electoral votes might use the USPS state code as the common linking field. The field you use must match a state identifier field in the spatial data set containing the state boundary information.

As always, RDMS staff are available to work with you on data extraction and modification tasks to prepare the data for the web site.
