Data Inventory Report and Revised Plan

Place your report on your web site by October 19th, 10am, and be prepared to show your ArcView Project in class. Projects in which there is still a large amount of data development to be done should contact me if it will be impossible to meet the due date for this assignment.

The purpose of this assignment is to present your revised project plan, organize your project database and to present a final report on its contents and structure.


Revised Project Plan

Please briefly report on your project plan as it now stands.  Include:

  • Revised description of your project purpose
  • What you have achieved to date
  • A list of steps you expect to follow with tentative dates
  • Expected final products
  • A revised list of bibliographic and/or internet sources relating to the project topic

Your plan should include a bibliography that uses accepted APA or MLA style citation formats for both paper and electronic sources.  For more information on correct citation of electronic resources, go to the Community and Regional Planning Program home page (http://www.ar.utexas.edu/planning), and then to Student Resources. There you will find a Guide to the Proper Citation of Electronic Information.


Database Report

You should now be able to complete to the best of your knowledge the metadata information you have been developing, both for existing data and data you have created (graphics and attributes). If the metadata already exists on the web, you may link to the metadata, but please supply any additional helpful information you can obtain. If you have not been able to find all the information, indicate "unknown".

  • layer (theme) name (e.g., parcels)
  • short description
  • type of feature (e.g., point, line, or polygon; raster grid; TIN; image)
  • Include a small image of the data theme as an example of what it looks like (see the Texas Natural Resource Conservation Commission GIS - Regulated and Monitoring Sites web page as an example)
    (hint: in ArcView, with a theme open in a view, choose File-Export - in the dialog box, choose jpeg from "list files of type" and then navigate to a folder to save this image file - if you want a small image, make sure your view is also small - the image will be the same size as the view)
  • data source (include web site if applicable)
  • original data source format (e.g., shape file, .e00 file, .dxf, .tiff)
  • original source scale or resolution if known (e.g., 1:24,000)
  • source date if known (when was the data set created?)
  • map projection and map units
  • attribute items (include any code descriptions if applicable)
  • attribute item source if known
  • any related attribute tables required (e.g., for a parcels theme, a related table containing tax assessor information by parcel)
  • quality assessment - assess as well as you can the quality of the data theme, including comments on the following:
    1. quantitative assessment of positional accuracy if possible (e.g., +/- 20 feet )
    2. qualitative assessment of positional accuracy (your comments/warnings about positional accuracy)
    3. completeness (Does it cover the area you need and is all information for the entire area present?)
    4. currency (Is it up to date? If not, how will that affect your project? What will you need to do to bring it up to date?
    5. qualitative assessment of attribute accuracy for critical attribute items (e.g., land use codes, street address ranges, street names, etc.)
    6. logical consistency if applicable (E.g., for roads , streams or sewer lines - do they connect?)
  • Brief description about what, if anything, you have done to correct, update, or expand on existing data themes (E.g., do you have to edit stream lines so that they fit an orthophoto of higher accuracy? Do you need to add attribute items?)


Project Database

Each project should have an ArcView Project File that will display all the data themes and tables for your project database. You may have all themes in one view, or in separate views or in any combination of views.  Each view should have an informative name (e.g., not View1), and each theme should have an informative name (e.g., not cenline.shp).  Themes should be displayed so as to provide useful but not overwhelming information for a user taking a brief look at the database.

Please be prepared to briefly (5 minutes) bring up your project file in class.
