Geodata Archive Owner’s Manual

A geographic information system is not built entirely from scratch. Invariably, new work incorporates pre-existing datasets chosen for their robustness and relevance to the topic under investigation. The work of rounding up reference-quality spatial data is the geospatial technology equivalent of an academic literature review. Unfortunately, we need to confront the “rounding up data” learning curve before moving on to the actual construction of a geographic information system. Let’s use a hypothetical situation to illustrate the process. Assumptions:

  • We’re using a workstation attached to the UWGB Network and running ArcGIS Desktop.
  • We have a bunch of Wisconsin data points and one of our project objectives is county-level analysis of the data.
That means our data hunt needs to include a feature class which will allow us to overlay county boundaries on our input data. We aren’t necessarily going to be able to use the first dataset we find. Characteristics such as accuracy, resolution and up-to-dateness need to be considered. We also need to consider the technology that we will use to add the data to our map document.

Find A Feature Class

The most direct way to make the necessary accomplish this is to find an Esri shapefile or geodatabase feature class from a reputable source and copy it into the project workspace. The upside of this approach is that the components of our GIS are being gathered in one location and the hassle of finding individual pieces later is reduced.
Data Files Accessed “In Place” – The local storage approach described above has a huge downside. It’s a given that the project workspace is on rigorously backed up local hard drives or shared network drives. This kind of space is often scarce and expensive. To the extent possible it should be reserved for files created specifically for the project. with automaticdd backed up on drives can result in chewing up disk space needed for project workspace needs to be on a disk is scarce

The Biodiversity Center's Geodata Library (K Drive Subset) The so-called "K-drive" is a share on the UWGB network configured for static storage. Mapping the share enables the user to add spatial databases stored there to an ArcMap map document open on his/her machine.
Map the campus computer network's K drive
In Windows File Explorer:

  • Right-click on This PC, then select Map network drive... from the popup menu.

  • Select the drive letter for the Geodata share. Using any letter other than K: will result in future problems connecting to individual datasets on the drive (red exclamation points).

  • The folder name for the Geodata share is \\fstorea\geodata$

Internet download portalsSay we are building a geographic information system and we've identified a specific dataset that's essential to the tasks we want to accomplish with our GIS. is needed for the that is under construction may be via download portals. Standard Internet search tools are used to find the specific datasets that meets the needs of s needed to round out need, one approach There are thousands of download portals. Finding the ones that serve up the particular datasets needed for the GIS that is being constructed can be quite a challenge. Once found, the needed datasets are downloaded to local or network drives. Check out our Selected Download Portals web page for a list of sites that we've found useful in our work.

Network Library - Locate the needed data file(s) on a local network drive such as UW Green Bay's Geodata Drive. "Frozen" data files stored on a network drive
Local Data Collection - Locate the needed data file(s) in a local collection such as the GEODATAFIX Section of UW Green Bays Geodata Archive. DIY

Finding and Vetting Reference Data – Knowing where to look – government hosted download portals and services. Knowing what to look for – Does metadata exist? What does it say about the robustness and timeliness and Reviewing Metadata The “old-fashioned” approach to collecting the reference data needed for a particular geographic information system is to take possession of the datafiles and store them on a local or network drive connected to the author’s workstation. More recently, many databases have been published as streaming map services.

Reference Data Held and Curated At UW-Green Bay – In response to the needs of natural sciences faculty and students, the Cofrin Center for Biodiversity has been collecting and storing spatial data since 2003. The scope and design of the CCB’s spatial data library has evolved over time and it is currently referred to as the “Geodata Archive”.

Note that this material (web page section titled “Reference Data Held and Curated At UW-Green Bay” and its linked articles) constitute the best available owner’s manual for the Geodata Archive. Technically the material belongs on a Biodiversity Center-owned website and that is where it was developed and published until early 2016. Unfortunately that option became unavailable at the same time the content needed a substantial update. To make sure the most recent information was available to users of the archive, we recreated the owner’s manual here on ottergeospatial.info. I know that the Biodiversity Center leadership is strongly committed to documenting their work and have a strategy in mind for getting this content back on to a Biodiversity Center-owned website. In the meantime we’ll maintain the information on our site and try to keep up with new developments.
